  1. 1. LSMW Step by Step Guide to Upload New Customer Master Record Legacy System Migration Workbench (LSMW) Author Satish Kumar Gunda2007/Q3 © satish.gunda@yahoo.com
  2. 2. LSMW Step by Step Guide to Upload New Customer Master Record Legacy System Migration Workbench (LSMW)The LSM Workbench is an R/3-based tool that supports you when transferring data from non-SAP systems ("Legacy Systems") toR/3 once or periodically.The tool supports conversion of data of the legacy system in a convenient way. The data can then be imported into the R/3system via Batch input, Direct input, BAPIs or IDocs. LSM Workbench provides a recording function that allows to generate a"data migration object" in an entry or change transaction. Through LSMW, we can upload Master Data and Transaction Data.The main advantages of the LSM Workbench: Part of R/3 and thus independent of individual platforms A variety of technical possibilities of data conversion Data consistency due to standard import techniques • Batch input • Direct input • BAPIs (Business Application Programming Interfaces) • IDocs (Intermediate Documents)The import technique to be used in an individual case depends on the business object. • Generation of the conversion program on the basis of defined rules • Clear interactive process guide • Interface for data in spreadsheet format • Creation of data migration objects on the basis of recorded transactions • Charge-free for SAP customers and SAP partners2007/Q3 © satish.gunda@yahoo.com 2
  3. 3. LSMW Step by Step Guide to Upload New Customer Master RecordData can be imported from Legacy Data on the PC or from the Legacy Application Server, The imported data will be converted toSAP format, to convert the data we create • Structure Relationships, • Field Assignments and • Conversion Rules,The, converted Data can be exported in SAP through • Batch Input Processing • Direct Input Processing and • Inbound IDoc Processing2007/Q3 © satish.gunda@yahoo.com 3
  4. 4. LSMW Step by Step Guide to Upload New Customer Master RecordLSMW to Upload Customer Master Records with Standard ObjectLet’s see an example of uploading Customer Master Record with Standard Object. Go to transaction code LSMW; create anProject CUSTOMERS , Subproject Object XD01 and Object CUST_NEW as shown below, then click Execute.The main screen of LSMW provides wizard-like step-by-step tasks. To complete your data conversion, you need to execute thesesteps in sequence. Once a step is executed, the cursor is automatically positioned to the next step.2007/Q3 © satish.gunda@yahoo.com 4
  5. 5. LSMW Step by Step Guide to Upload New Customer Master RecordOn the initial screen, you can create a new project, corresponding subprojects and objects via Edit -> Create new entry.• Project : An ID with a maximum of 10 characters to name your data transfer project. If you want to transfer data from several legacy systems, you may create a project e.g. for every legacy system.• Subproject : An ID with a maximum of 10 characters that is used as further structuring attribute.• Object : An ID with a maximum of 10 characters to name the business object.In the initial screen, All objects provides a list of all projects created already. My objects displays a list of all objects you createdpersonally. All objects of the project displays all objects of the selected project as tree structure. Project documentation displaysany documentation written for the individual pop ups and processing steps. you can print the project documentation out, send itand save it in various file formats.Select Documentation to enter your notes. After clicking, a popup is displayed in which you can write down your personaldocumentation. The documentation function is additionally available under Administration and Recordings in the first seven stepsof data migration.Below, you find an example for a project with several subprojects and objects. This representation is displayed by pushing thebutton All objects of the project:Note that these steps may look different depending upon your Personal menu settings. You could make step numbers visible by‘Numbers on’ icon or hidden by ‘Numbers off’ icon. You can execute a step by double-clicking on the row. Toggle icon‘Doubleclick=Display’ or ‘Doubleclick=Edit’, makes the step in ‘display’ mode or ‘change’ mode.2007/Q3 © satish.gunda@yahoo.com 5

  7. 7. LSMW Step by Step Guide to Upload New Customer Master RecordStep 1: Maintain Object attributesYou will be updating the customer master records with the help of Standard Batch Input; therefore, choose radio-button StandardBatch/Direct Input as shown below. Enter Object ‘0050’ for Customer Master records and default method ‘0000’ and click onSave.Step 2: Maintain Source StructureThe source structures (LS structures) are defined with the ID, name, and hierarchical relationships. Start with the highesthierarchy level since only hierarchies with the same level or a lower level can be created.Select Create (Cont+F4) then give description as below.2007/Q3 © satish.gunda@yahoo.com 7
  8. 8. LSMW Step by Step Guide to Upload New Customer Master RecordStep 3. Maintain Source FieldsKeep the cursor on XD01 (our Source Structure) and click on “Table Maintenance” icon.In this step, you need to list the fields are present in the source structure. The easiest way is to click on ‘Table Maintenance’icon to enter Fieldname, Type and Length for each field. If your fields are more, I suggest type them in Excel and Paste themSAP. Now paste it hereStep 4: Maintain Structure RelationsThe Standard Object ‘0050’ we maintained in the first Step requires BGR00, BKN00 and BKNA1 to be maintained irrespective of uneed changes init or not. The only logic for this is, all the top Structures to be assigned to reach up to the bottom. For ourscenario, we need to update BKNA1, BKNB1 and BKNVV. (If you do not maintain Structure relations for mandatory entries, you2007/Q3 © satish.gunda@yahoo.com 8
  9. 9. LSMW Step by Step Guide to Upload New Customer Master Recordmight get a message such as ‘Target structure BKNA1 needs a relation to a source structure’.) Even though you don’t want toupdate any fields in these structures, you NEED to create a relationship with source structures. In all, you need to createrelationship for four target structures. Create relationship between source structures XD01 with these target structures with icon‘Create Relationship .Keep Cursor on these four target structures and click on icon ‘Create Relation’ and structure relations are maintained2007/Q3 © satish.gunda@yahoo.com 9
  10. 10. LSMW Step by Step Guide to Upload New Customer Master RecordStep 5: Maintain field mapping and conversion rulesHere, our Transaction Code is constant throughout the process, so we maintain it as Constant to do this, keep your cursor on‘TCODE’ field and click on ‘Insert Rule’ icon2007/Q3 © satish.gunda@yahoo.com 10
  11. 11. LSMW Step by Step Guide to Upload New Customer Master RecordAssign rules:Initial: This deletes the coding assigned to the target field. In addition, source fields assigned to the target fields are removed as well. Depending on the object type, the target field is assigned the following value: ⎯ For standard batch input/standard direct input: Nodata characters (determined e.g. in session header BGR00, BI000) ⎯ For batch input recording: / as nodata character ⎯ For BAPIs, IDocs: Clear field (i.e.: character field blank; numeric field 00...0)Move: The data is transferred using ABAP command "Move". For source fields that are not of type C or N, this means: Packed field Unpack to target field WRITE...TO... Popup to select e.g. 01.10.1998 - internal format Date field - user format - … YYYYMMDD Batch input/direct input: The amount value is edited according to the format Amount field settings in the user master. BAPIs, IDocs: The amount value keeps the internal calculation format.2007/Q3 © satish.gunda@yahoo.com 11
  12. 12. LSMW Step by Step Guide to Upload New Customer Master RecordConstant: The target field is assigned a fixed value.Fixed value (reusable): A "fixed value object" (variable) named FV_<fixedvalue> is assigned to the target field. This fixed valueobject is filled with an actual value in step "Maintain fixed values, translations and user-written routines".Translation (reusable): The target field is assigned coding carrying out field contents conversion using a translation table. Thevalues of this translation table can be entered in step "Maintain fixed values, translations and user-written routines" see Error!Reference source not found..Prefix: Specify any prefix to precede the contents of the source field.Suffix: Specify any suffix follow the contents of the source field.Concatenation: You can concatenate two or more source fields.Transfer left-justified: Transfers the contents of the source field in left-justified form.ABAP coding: Double-clicking on a target field branches off to the ABAP editor. There you can edit generated ABAP coding orwrite and save your own coding. A large part of the usual standard R/3 editor functions, such as Check (syntax check), PrettyPrinter, etc., are available there.Under Insert you can add the following to your coding:• source fields: all source fields available are displayed for selection• global variable: see 5.7• global functions: see Error! Reference source not found.XFIELD: This is a special function for processing of IDocs. In some cases an ‘X-structure’ exists in addtion to the data transferstructure (where the values for the import can be found); the fields of this ‘X-structure’ have to be filled with ‘X’ or blank to decide ifthe corresponding field in the data transfer structure should be transfered or not.2007/Q3 © satish.gunda@yahoo.com 12
  13. 13. LSMW Step by Step Guide to Upload New Customer Master RecordChoose radio button ‘Constant’ to enter value ‘XD01’ transaction code. In the same way select the fields that you want to maintainconstant values and give values, like company code, currency, etc., Here I have given many constant values like SalesOrganization, Distribution Channel, Division, Customer A/c Group and many other. But I have selected only 7 fields that arevariable from customer to customer, for which we have created in source field. So to assign a source field, keep the cursor on thefiled like NAME1 and select Source Field and select NAME1. And in the same way for all the 7 fields we havemaintained the source. Here exactly match each field with its source field.2007/Q3 © satish.gunda@yahoo.com 13

  17. 17. LSMW Step by Step Guide to Upload New Customer Master RecordStep 6: Maintain fixed values, translations, user-defined routinesYou can also maintain re-usable translations and user-defined routines, which can be used across conversion tasks. In this case,that step is not required.Before continuing to the next step we have to have the source file to upload. First we create it and then will move to next step.First create file Excel like below.And Save as Text (Tab delimited) like below2007/Q3 © satish.gunda@yahoo.com 17
