Variant Configuration Overview

VARIANT CONFIGURATION OVERVIEW Prepared by Arun prasad C R *Please place your comments

Variant Configuration Introduction: • Variant Configuration is useful if you have a large number of combination of parts that go into a product. It means different permutations and combinations of the parts for same material. • If you maintain a unique material code for each possible combination of parts, you require a large number of material numbers. • Usually involves Make to Order Production Process Variant Configuration Examples: • A customer ordering a computer can choose different combinations of monitor, CPU, keyboard. • A customer ordering a car can choose different combinations of accessories and color. • In a business involving steel manufacturing, the customer may order steel involving different physical properties like tensile strength, diameter.

Overview of Terms Variant Configuration Source: SAP

Overview of Terms • A configurable material has a special bill of material called the Super BOM in which all possible combinations are stored. • The product is configured in the sales order by choosing the required Characteristic Values. • The requirements are passed on Production Planning. On Explosion of the Bill of Material, the system selects the components assigned to the characteristics values in the order. Variant Configuration • After production, the material is assigned as sales order stock for delivery to customer. Source: SAP

• Sales Order Processing

MTO Process Overview Make-To-Order Production With a Configurable Product: In this process, you create a sales order in SD and transfer the requirements to PP. The requirements are checked using MRP, before a production order is generated. This production order is created in PP. Shipping and billing both occur in SD. Finally, you check the costs and revenues in CO. Variant Configuration Source: SDN

Creating a Sales Order (T Code :VA01) • After entering the sales data, a configuration screen pops up. • Configure the material by selecting the characteristics. • Note that the value of Variant Conditions changes as per selection. Variant Configuration Source: SAP

Creating a Sales Order (VA01) • The system allows analysis of Object Dependencies and Variant Conditions. • Item Category determined in Sales Order is TAC. • Note the Material Availability Date and save the sales order (for test11048 and 11059). Variant Configuration Source: SAP

Classification System: Characteristics CT04: Create characteristics • Data type can be CHAR, NUM, DATE, TIME, CURR Variant Configuration List of values and default value for characteristics can be stored in Value tab. Source: SAP

Reference Characteristics Reference characteristics are characteristics that refer to table fields. Variant Configuration Tables / Structures whose filed values can be changed by dependencies: SDCOM - Communication between SD and Variant Configuration VCSD_UPDATE - Table for Updating Sales Documents from the Configuration MMCOM, STPO, PLPO, PLFH, PLFL Tables / Structures whose filed values can be read by dependencies: VBAK, VBAP, VBKD, VBPA_AG, VBPA_WE, VBPA_RE, VBPA_RG VEDA, MAEPV, MAAPV Source: SAP

Classification System: Characteristics CT04: Create characteristics • Object dependencies like pre conditions, selection condition, action, procedures can be created for characteristics • Object dependencies like pre conditions, action, procedure can be created for characteristic values Variant Configuration Source: SAP

Classification System: Class CL01 /CL02: Create class under class type 300 for Variants Variant Configuration Assign the characteristics to the class. During Material Master creation for Super BoM, this class will be used in the Classification view. Source: SAP

Material Master of Super BoM (MM02) • Basic Data 2 Screen: Set ‘Material is Configurable’ Indicator • To determine item category TAC in sales order, maintain a suitable item category group such as 0002 • MRP 2 View: Procurement type ‘E: In house Production’ • MRP 3 View: Strategy Grp. ’25: Make-to-order for configurable’ used for demo • MRP3 View: Availability Check ’02: Individual Requirement’ • Classification view: Attach the variant class Variant Configuration Source: SAP

Bill of Materials (CS01 / CS02 / CS03) Variant Configuration Source: SAP

Object Dependency in BoM (CS02) Components in Production Order can be selected using Object Dependency type Selection Condition Variant Configuration Source: SAP

Routings (CA02) Operations in Production Order can be selected using Object Dependency type Selection Condition Variant Configuration Source: SAP

Configuration Profile: Process Planned/production Order; explosion indicator None (others Single level or Multiple level) The material has a BOM that is not relevant to the sales order. Only the characteristics that describe the variant are required. The components are determined later during material requirements planning or production, so there is no need to explode the BOM in the sales order. Sales order (SET): See next slide also In the sales order, sales-relevant components are shown as sub-items of the header material. Requirements are transferred and pricing is calculated at component level, not at header material level. Order BOM You create a sales order. In order BoM, you can insert extra items or delete items manually. The Variant Configuration changed BOM is stored as a separate BOM for the sales order. Source: SAP CU42

Configuration Profile: SET This processing form means that in the sales order you can only process sales-relevant BOM items. You can use the item category group like 0004 at configurable material level to define that requirements transfer and pricing are at component level. For example, a PC is made up of the components monitor, CPU, keyboard, and printer. These components are all salable materials that are manufactured separately. In the sales order, you want to see the individual components that make up the computer as order items, as well as the whole computer. In the sales order, these products are grouped together in a SET. For this reason, this type of processing is also referred to as set processing. Variant Configuration Source: SAP

Configuration Profile: Dependencies Dependencies like Actions and Procedure can be assigned to Configuration Profile. Variant Configuration Source: SAP

Configuration Profile: Variant Table • Tables are used to store combinations of values for different characteristics • A table HD_1300_COLOR_PR is created in CU62 transaction. It has 2 fields: HD_COLOR (key field) and SURCHARGE. The selected characteristic will be transferred to HD_COLOR and surcharge to SURCHARGE2. • The table contents are given below (see transaction CU60) Variant Configuration VK30: Has description entries for the surcharge column listed above VK12: Will pick up pricing value based on condition type VA00 Source: SAP

Pricing Check definition of characteristic SURCHARGE2 – Additional data tab -> reference table and field Variant Configuration Simple method to achieve Variant Pricing is given below: • Create multiple value characteristic SURCHARGE2 referring to SDCOM-VKOND. • Put this characteristic in the class HD-000 which was used for the configurable material • Now go to CT04 and change the Characteristic HD_COLOR Go to values tab and select Red. Go to Extras-> Object Dependencies->Editor and then select Procedure. In front of 000010 Enter $self.surcharge2='HD-003_03'. Similarly Select Black to enter $self.surcharge2='HD-003_02‘. Same way 'HD-003_01’ for Silver • VK30: Has description entries for the surcharge column listed above • VK12: Will pick up pricing value based on condition type VA00 Source: SAP

Pricing VK30: Maintain descriptions for variant price conditions (optional step; done while creating dependencies for surcharges; maintains consistencies of configuration) Variant Configuration VK11 / VK12: Maintain actual condition record for variant price surcharges Source: SAP

Pricing Factors Pricing factors can only be maintained on characteristic level. The syntax of pricing factors is as follows: $SET_PRICING_FACTOR ($SELF, <characteristic>, <variant key>, <factor>) This expression contains the following information: • The characteristic that refers to structure SDCOM, in which variant conditions are defined. • The variant key used to infer the condition for a characteristic value. Variant Configuration • The factor by which the surcharge increases. Source: SAP

Material Variant • For variants that are required frequently, create material variants, which can be produced without a sales order and kept in stock. • When a sales order is received, check whether the variant is in stock and deliver immediately. • The material master record of a material variant is linked to the configurable material and configured using the characteristics of the configurable material. Variant Configuration Source: SAP

Summary of day 1 By now, you should be comfortable with the following topics: • Explain what Variant Configuration is and its use in make to order scenario • Using Variant Configuration during sales order processing • Configuration details like item category and condition types • Classification System - Characteristics and Classes • Super BoM, Configuration Profile, Object Dependencies • Pricing Surcharges in sales order processing Variant Configuration • Using Material Variants for make to stock scenario Source: SAP

• Day 2: Understanding Object Dependencies in detail

Dependency Types Variant Configuration Source: SAP

Pre Condition Variant Configuration Only if the model specified is racing, the bicycle can have 21 gears. 1. Create a precondition with the following source code: MODEL eq 'Racing' and Specified MODEL 2. Allocate the precondition to value 21 of characteristic GEARS Source: SAP

Selection Condition A selection condition is allocated to each component and each operation. This selection condition determines which components and operations are selected for a variant. Variant Configuration Source: SAP

Changing Master Data with Dependencies In variant configuration, you can use reference characteristics with dependencies to change field values of tables for bills of material (BOMs), task lists, and master recipes. Table names and fields are given below for reference. Table STPO field MENGE can be used to change component quantities of BoM. Table PLPOD field VGW01 can be used to change setup time of Operation. Variant Configuration Source: SAP

Procedures Procedures can set default values for a characteristic (can be overwritten by the user) Variant Configuration Source: SAP

Procedures • Set default values: $SET_DEFAULT ($SELF, <characteristic>, <term>) For example: ( $SET_DEFAULT ($SELF, COLOR_CHAR, 'BLUE'), $SET_DEFAULT ($SELF, GLOSS_CHAR, 'NONE') ) IF $root.PC_CASING_CHAR = 'TOWER' • Delete default values: $DEL_DEFAULT ($SELF, <characteristic>, <term>) Variant Configuration Produce a sum of the values for a characteristic in a multi-level configuration: $SUM_PARTS ($SELF, <characteristic>) It can be used to calculate the weight of components and transfer the same to structure VCSD_UPDATE, gross weight field BRGEW • Add the components of a BOM together: $COUNT_PARTS (<$SELF>) • Surcharge for variant conditions in Pricing: $SET_PRICING_FACTOR ($SELF, <characteristic>, <variant key>, <factor>) Source: SAP

Constraints and Dependency Net The main purpose of a constraint is to monitor the consistency of a configuration. There are four sections in a constraint. 1. OBJECTS: Declaration of all classes and objects used. 2. CONDITION: Pre requisite for processing the constraint. 3. RESTRICTIONS: For interdependencies and consistency check; check and set values. 4. INFERENCES: Enter the characteristics for which characteristic values are to be inferred. Variant Configuration Constraints are grouped together in dependency nets. The dependency net can be allocated to a configuration profile. Example: The hard disk can only have the value ‘1620’ for a tower, or ‘850’ for a mini tower. OBJECTS: PC IS_A (300) PC RESTRICTIONS: PC.HARD_DISK = ‘1620’ if PC.CASING = ‘Tower’, PC.HARD_DISK = ‘850’ if PC.CASING = ‘Mini tower’. Source: SAP

Actions Actions can be used to infer values for characteristics. Actions can also be used to change field values in BOM items or operations in routings. Procedures can set default values for a characteristic, which can be overwritten by the user. The user cannot overwrite values that are set by an action. For new developments, use Procedures rather than Actions (to become obsolete) Variant Configuration Source: SAP

Object Variables used in Multi level configurations Variant Configuration Source: SAP

Allowed Dependency Types • Preconditions are allowed for characteristics and characteristic values. • Selection conditions are allowed for characteristics, BOM items, operations, and production resources/tools. • Procedures & Actions are allowed for characteristics, characteristic values, BOM items, operations, and configuration profiles. • Constraints can only be linked to a configuration profile via dependency nets. Variant Configuration Source: SAP

Processing Sequence for Dependencies • Each time you enter a value for a characteristic on the value assignment screen and confirm the value, the system processes all the dependencies. • The dependencies are processed in the following sequence: 1. All actions several times, until no more values can be inferred. 2. All procedures exactly once in the following sequence: a) Procedures for the configuration profile in the order you defined b) Procedures for characteristics Variant Configuration c) Procedures for characteristic values The procedures for each characteristic or value are processed in the order you defined. 3. Actions Values set by procedures can also trigger actions. For this reason, all actions are processed again. 4. Preconditions 5. Selection conditions for characteristics Constraints are processed in parallel with points 1–3, if all the objects in the OBJECTS section are present, and if all the conditions in the CONDITIONS section are fulfilled Source: SAP

• Transfer to Production Planning (Demo)

2. Checking Requirements Using MRP (T Code :MD04) Step1 to create sales order has already been discussed earlier. 2. Stock Requirements List: • The sales order is displayed as a separate planning segment (sales order stock required on material availability date and sales order). Variant Configuration Source: SAP

3. Requirements Planning (T Code :MD50) The sales order will now be converted into a planned order. Planned Orders represent the first step toward an actual production schedule for the Shop Floor. Variant Configuration Source: SAP

4. Convert the Planned Order into a Production Order (MD04) • Planned Orders are a result of MRP run and serve to provide an initial Production Schedule. • Production Orders contain comprehensive information to support a shop floor schedule and provide a method to confirm operations performed. • Production orders can be created with reference to a Planned Order. Variant Configuration Source: SAP

4. Convert the Planned Order into a Production Order (MD04) Object Dependency: BoM Selection Condition ensures only necessary material components are taken. Variant Configuration Source: SAP

4. Convert the Planned Order into a Production Order (MD04) Object Dependency: Routing Selection Condition ensures only necessary operations are taken. Variant Configuration Source: SAP

4. Convert the Planned Order into a Production Order (MD04) Prior to release of order, it is not possible for anyone to enter confirmations for the operations in the order. Release the Order and Save it. Display the operation scheduling overview, choose Goto  Graphic  Gantt chart. Variant Configuration Source: SAP

4. Convert the Planned Order into a Production Order (MD04) Display the planned costs, choose Goto  Costs  Analysis Variant Configuration Source: SAP

5. Confirming Production Order (CO11N) Production Control  Confirmation  Enter  For Operation  Time Ticket Variant Configuration Source: SAP

5. Confirming Production Order (CO11N) • Back flushing (posting of an issue of components or material withdrawals) • Storage of the finished product in the warehouse to sales order stock • Goods Movements are posted (errors if any can be corrected in COGI) • Actual costs are calculated • Just in case, to close the order without yielding a product, perform Restrict Processing -> Technical Completion for Production Order in CO02. Variant Configuration Source: SAP

5. Confirming Production Order (CO11N) • Sample Material Document and FI document entries are shown below Variant Configuration Source: SAP

6. Checking the Settlement of the Production Order From the Production Control node, choose Period-End Closing  Settlement  Individual Processing (KO88) Perform order settlement to transfer the costs of the production order to sales order. Analyze the current cost situation for the Production Order Variant Configuration Source: SAP

7. Creating a Delivery (VL10G for delivery due list, VL01N for single delivery) Assign a serial number to the material. Pick and post the goods issue. Movement type will be 601 E indicating delivery from sales order stock. Accounting document will be generated to capture the change in inventory. Variant Configuration Source: SAP

8. Creating Billing Document (VF04/VF06 for due list, VF01 for single invoice) VF01: Create the invoice – sample accounting entries (without tax) are shown below F-28: Receive the payment from the customer Variant Configuration Source: SAP

Other Information • CRM: It is possible to have configurable products among your Online Store offerings using the IPC (Internet Pricing and Configurator). It allows customers to interactively choose product options via an easy-to-use interface. Customers can mix- and-match these options to build the exact product they wish to purchase. • ECC 5.0: Single transaction PMEVC – Modeling Environment for VC Variant Configuration Source: SAP

Summary By now, you should be comfortable with the object dependencies and the following topics: • Pre conditions • Selection conditions • Procedures • Actions • Constraints and Dependency Net Variant Configuration • Transfer of sales order requirements to PP • Delivery from sales order stock • Invoicing the customer Source: SAP
