SAP Transaction and BAPI Knowledgebase

The SAP GUI is the default application for updating and viewing SAP data. While it is aimed at business and power users, it is quite an inaccesable rich client windows application with limited search functionality and the requirement to know many SAP "transaction codes" off the top of your head.

To help me (and you) a little, below is a list of some of the most useful transactions available in the SAP GUI Tool (pictured below). I've had to use them all more than once in my current SharePoint to SAP Integration Project and especially in writing combined SAP/SAP BPM/SharePoint technical specifications:

SAP Transactions (enter through SAP GUI transaction area in the top left hand side)

Note that you can prefix a transaction with /o (instead of /n) which will open the transaction up in a new window in the SAP GUI e.g. /ose11 for the ABAP dictionary
  1. /nse11 = ABAP Dictionary (for maintenance of tables and table data)
  2. /nse16 = Data Browser for Tables
  3. /nbapi = official UI for looking for built-in BAPIs with full documentation.
  4. /nse37 = Function Builder (for searching for custom BAPIs not in /nbapi)
  5. /ose24 - to find SAP classes (not BAPIs). Look here if you cannot find a BAPI that will do the job e.g. Vendor creation
  6. /soamanager = SOA manager
  7. /nsicf = Maintain web services
  8. /nswf_bam = Business Activity Monitoring (for SAP BPM)
  9. /nse80 = object explorer
  10. /nse10 = Transport Organizer (to see what is in a transport)
  11. /nXK02 = Change Vendor
  12. /nxk01 = create vendor
  13. /nme23n = Official Display Purchase Order, click “Other purchase order”
  14. /ncj03 = Display Project (NB. typically, any business object transaction ending in 01 is for create, 02 is update, 03 is for display)
  15. /h - turn on ABAP debugging (so you can work out what SAP GUI screens are doing in the background). Also allows you to write to tables directly with a workaround.
  16. /ncat2 - Timesheet entry
  17. /ncat7 - Transfer to Controlling (FICO).
  18. /ncats_da - Display Working Times
  19. /npa30 - Maintain HR Master Data.
  20. /nsu01 - User maintenance - so you can unlock users in SAP
  21. /nsxmb_moni - (For PI Server) - Integration Monitoring
Commonly Used Tables
  1. LFA1 - Vendor Master
  2. LFM1 - Vendor master record purchasing organization data
  3. EKKO - Purchasing Document Header
  4. EKPO - Purchasing Document Item (aka Line Items in your Purchase Order)
  5. T016 - List of Industries
  6. T000 - Clients
  7. T001 - Company Codes
  8. T005 - Countries
  9. T005 - Unit of Measurement (e.g. EA, Square Metres)
  10. PROJ - Projects
  11. PRPS - Work Breakdown structure (WBS) - basically project line items
  12. SKA1 - General Ledger Account master (aka Chart of Accounts)
Enterprise Services Additional Notes
  1. AccountDeterminationExpenseGroupCode is synonymous with GL (General Ledger) Code when working with Purchase Order Enterprise services.

    The SAP GUI - definitely not an intuitive application
