  1. 1. Functional Spec?Functional Spec is mainly prepared for the purpose of developing the new reports (this happens onlywhen SAP standard report not achieve the client purpose) using the ABAP Program. for ABAPers youneed to give the details of the Tables , Fields and the logic how to pick the value and get the report.The information contains in the functional specs are:a)Document segment (BSEG): which contains the company code,posting keys, vendors,etc.b)the line items(BKPF) consists of document type, etc.for example: from BSEG table you have to go to the field of BUKRS for company code, BSCHL forPosting Keys.From BKPF table you have to go to the field of BELNR for document Number, etc.Based on your functional specification the Abaper will design the report using his technical specifications.The above are examples only to understand. There are plenty of tables & fields for FI, CO and Assetsseparately.Please assign points, if the above are useful.Functional spec are based on the business requirment and contains details of end userexpectations of the product Functionality document describes requested properties of inputs and outputs the blueprint for how you want a particular application to look and work it details what the finished product will do who a user will interact with it and what it will look likethe key benefit of writing up a funtional spec is streamlining the development process. timeand productivity are saved during development stage because the programmers canprogram instead of also working out the logic of the user experienceS/W or program will be developed based on the functional specsit consist of 1. business requirments- brief detail about the business process and the need of your cutomized program/report 2. security consideration- who all can have access to this program and level of security whether it is at co.code level or country level 3. business dependences- whether is there any other process / program should have been completed before the execution of this program 4. Data requirement 5. priority- whether the failure lead to production stoppage or any work around 6. error management
  2. 2. 7. how the program retrieve the data if it is a report programEg:-1The requirement was to add the vendor name to the fbl3n screen, we couldn’t add this so we went for anew report with all the fbl3n fields + vendor name. This is a spec for the program.DEV ID; Sales tax reportFunctional Team ;Zaid Azam(phone)SAP Dev. Team (lead) Zaid Azam (phone #)(member) (phone #)Phase / Priority Phase 1MediumThe above part is just a header, which system the report is, in what report is it i.e sales report, materialreprot etc, then the consultants name, lead name etc.how important it is medium , low, highRevisionsRev.

  3. 3. 2.Functional RequirementsFunctional RequirementsSelection Posting Date, G/l accountNarrative flow; The report should list the all the transactions of the G/l account( all items i.e open andcleared) selected on the initial screen. It should list the vendor name and number when a G/l transactionis of a vendorAssumptions / issues;Should have the capability of being exported to excelThis is the important parthere you tell what are the fields on the selection screen.Then in the narrative flow you should tell the abapper what thre report should do like its mentioned above,eg ;apart from above get the sales for customers who reside in California between the date rangespecified on the selection screen3.Processing logicProcessing logicStep 1 Enter g/l account (HKONT) on the selection screen and run with or without a date range Or run bya date range only without specifying a G/LStep 2 Get the G/L number from BSIS that was selected on the initial screen Or get all the G/ls that hadpostings in the posting date ( BUDAT) specified on the initial screen.Step 3 Get the amount ( WRBTR) from BSIS ( Open and cleared both are in BSIS)Step 4 Take the Document Number (BELNR) from BSIS and get the vendor number for that doc numberfrom BSIK ( open item), from BSAK ( cleared) if item is paid.Step 8 Should get the vendor name from LFA1 for the vendor number from BSIK or BSAKStep 9Step 10Processing Logic tells him in detail about which fields should come and from which table( not necessaryto give technical names and tables, he could find that out, depends on the abbapper)4.OutputOutput4.1 LayoutFORMATG/L Posting date Amount Doc type Text Doc number Pk Vendor # Name650100 12/03/2006 500 SA Test for report 19000042342 4010229 GMCIn the format i put an excel view of how the final report should look like

Both header and line items are specified.Additional topicsUnit Test Suggestions: Same as the standard SAP report FBL3N. Only addition is the vendor name andnumberSecurity/ Authorizations:Error handlingDependenciesReferencesOut of scope requirements NA2. EgI need one new report like in the output i need only company code, Vendor number and recon. Accountassigned. like as below:Company Code Vendor Recon account1000 90000001 1560011000 90000002 1560012000 90000001 156002for the above requirement with the input selection criteria like as belowCompany Code ( ) ( )Vendor ( ) ( )if you give input selection as above as required you will get the output as given aboveLogic should be as below:for input selectionCompany Code - BUKRS is the ABAP field for the company codeVendor - LIFNRfor the outputCompany Code - LFB1-BUKRS
  5. 5. Vendor - LFB1-LIFNRRecon account - LFB1-HKONTYou will get the recon account details in the LFB1 table , if you give the logic as above , ABAP er will writethe program for the same.
