BADI`S

What kind of enhancements are possible?

Depending on your release there a lot of ways to enhance your system.

  • BAdI
    • classic BAdIs
    • kernel-based BAdIs from Enhancement Framework since Netweaver 2004s
  • User Exits (also known as CMODs/SMODs)
  • Appends to structures and database tables
  • additional values in fixed-value domains

What is a BADI?

BADI stands for Business Add-In. These are like user exits but are implemented using ABAP Objects. BADI's can be implemented in every stage of the systems landscape. That means there are more than SAP and Customer specific views, but also country or language specific views.

How to Search BADI for a Transaction?

?Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
Go to the Transaction, for which we want to find the BADI,
Get the Program Name of Corresponding Transaction.
(Click on System->Status. Double Click on Program Name)
Once inside the program search for 'CL_EXITHANDLER=>GET_INSTANCE'.
Make sure the radio button "In main program" is checked.
A list of all the programs with call to the BADI's will be listed.
The export parameter 'EXIT_NAME' for the method GET_INSTANCE of class CL_EXITHANDLER will give you the BADI name for the Transaction.

?Finding BADI Using SQL Trace (TCODE-ST05).


HOW TO FIND BADI`S?


Introduction

There are multiple ways of searching for BAdIs. My favorite one is using the Performance Trace (formerly known as SQL trace) transaction code ST05.

This analyzing technique is based on the fact that all BAdIs are registrated in SAP database tables. So for each BAdI call these database tables will be accessed. The BAdI database tables are SXS_INTER, SXC_EXIT, SXC_CLASS and SXC_ATTR. These tables are always accessed by the views V_EXT_IMP and V_EXT_ACT. So these two ABAP views (T: SE11) will be the basis for the trace.

BADI

The procedure to discover BAdIs by a Performance Trace will be explained by using the example used below.

Example case

I want to know which BAdIs are called in the transaction "Maintain Business Partners" transaction code BP.

Pre checks

  • Check if no other users (T:SM04) or batch jobs (T: SM50) are using the same user as you do.

    • Trace Actions

    Start the Performance trace

  • Start transaction ST05 (Performance Analysis)
  • Set flag field "Buffer trace"

    • Remark: We need to trace also the buffer calls, because BAdI database tables are buffered. (especially view V_EXT_IMP and V_EXT_ACT)

  • Push button "Activate Trace"

    • Execute the Business transaction

  • Start transaction BP in a new GUI session
  • Push button "Organization"
  • Fill in your test data
    • Name NL4B
    Street Olympia
    House number 1a/1b
    Postal code 1213 NS
    City Hilversum
    Country NL
  • Push button Save

    • Performance trace

  • Go back to the Performance trace session
  • Push button "Deactivate Trace"

    • Analyzing the Trace List

    Showing the Trace List

  • Push button "Display Trace"

    • The popup screen "Set Restrictions for Displaying Trace" appears

    Now we are going to filter the trace on Objects: V_EXT_IMP and V_EXT_ACT.

  • Push button "Multiple selections" button behind field Objects
  • Fill: V_EXT_IMP and V_EXT_ACT

    • image

  • Push button "Copy (F8)"
  • Fill Operations: OPEN
  • Push button Enter
    See the result:

    • image

    Interpreting the Trace list

    All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BAdI class interfaces. The BAdI name is after the IF_EX_.

    So the BAdI name of IF_EX_ADDR_LANGU_TO_VERS is ADDR_LANGU_TO_VERS.

    In transaction SE18 you can see the BAdI definition.

    (If you can’t find the BAdI definition name, search in table SXS_INTER.)

    Exporting the Trace list

    If you’d like to keep your analysis, you can export it to Excel file format.

    Actually the file will be saved in tab separated file format, but giving the file the extension .xls it will automatically be opened by Excel.

  • Start menu: List > Save > Local File
  • Select Spreadsheet
  • Push Enter
  • Fill your preferred file location and file name

    • image

  • Push button "Generate"
  • Open the file (in Excel)

    • image

  • Delete the columns and rows you don’t need and the result looks like:

    • image

    View V_EXT_IMP and V_EXT_ACT

    The reason for filtering the result not only on the view V_EXT_IMP but also on V_EXT_ACT is necessary, because not all BAdIs are implemented in the same way.

    For example:

    V_EXT_IMP catches BAdI BPTIME_BP001.

    V_EXT_ACT catches BAdI ADDRESS_SEARCH

    Tips

  • Make a full test entry in the Business transaction before starting the Performance analysis.
    So during the Performance trace you won’t make mistakes. Making mistakes during the recording will cause extra trace lines in your trace list.
  • Try to start with an empty Business transaction screen.
    This tip is best explained by an example.
    When I restart transaction BP after I have created, displayed or changed a business partner, the last opened business partner will be displayed automatically. This means also I will get extra trace lines in my trace list.
    To start again with an empty business partner screen you have to close all GUI sessions and login again.
  • In the Business transaction you need to fill all required fields so all BAdIs will be called.
