Question

hi folks,
I am working on the user exit (ZXPADU02) and I was trying locate the main program that was calling this include program.
This is what I got.
program name: SAPLXPAD - it is a Function Pool program
that has the include program LXPADUXX (has a group of function modules) that has the include 'LXPADU02' the FM  'EXIT_SAPFP50M_002' that contains the include program of the user exit 'zxpadu02'.
My question is. is the Function Pool program the main program or the enhancement name for the user exit or the starting point of the user exit OR is there a main report program (executable program) that calls this userexit?
Can anyone explain on this?
Thanks
Vinu.

    The function exit EXIT_SAPFP50M_001 allows you to enter Defaultvalues in
    the single screen when you are creating or copying infotypes.
    The following are available for determining these default values:
    o   TCLAS    the transaction class (A= employees, B= applicants)
    o   INNNN    the infotype created
    o   IPSYST   workfields for dialog control and selected fields for
        organizational assignment (IT 0001) that are valid on the start date
        of the current record (INNNN-BEGDA).
    o   I001P    Table T001P (Personnel Subareas) determined with the
        current organizational assignment (IPSYST-WERKS, IPSYST-BTRTL),
    o   I503     Table T503 (Employee Subgroups) determined with the current
        organizational assignment (IPSYST-PERSG, IPSYST-PERSK).
o   IPREF    Assignment values for HR objects
Read the field documentation for structure PSYST.
Based on this data, the additional data can be returned to parameter
INNNN.
Error messages or exceptions are not provided for in this function exit.
Note the following:
o   The function exit is executed when you Create or Copy a record.
o   As long as the enhancement is active, the function exit is called up
     for every infotype, as the following steps are necessary:
     -   declaration of structure with desired infotype structure (I0008
         LIKE P0008)
     -   infotype query in CASE statement
     -   temporary storage of transfer parameter INNNN in infotype
         structure
     -   an example of the coding for this function exit is stored in
         include LXPADF01.
o   You can use function module HR_READ_INFOTYPE to read further
     infotype data.
