PM01 - Custom Infotype Creation

Go to SM30 - V_T591A and maintain subtypes for the custom infotype.

If you want the subtype to be mandatory, then select "Subtype mandatory" from V_T582A.

Then go to V_T777D and for that specific infotype fill subtype field as SUBTY and subtype table as T591A.

User Exits - PBO and PAI (ZXPADU01) and (ZXPADU02)

The standard way to implement Process before output (PBO) - Defaulting of fields and Process After Input (PAI) is to write your code into two programs:-

ZXPADU01 - For PBO
ZXPADU02 - For PAI

In SAP FM EXIT_SAPFP50M_002 and EXIT_SAPFP50M_001 it will trigger the includes ZXPADU01 and ZXPADU02

Some code snippets that may be useful is as below. Use this to convert structure into a variable and convert it back at the end of the code

 DATA: i0011 TYPE p0011.

   WHEN '0011'.      "ext bank transfers
     CALL METHOD cl_hr_pnnnn_type_cast=>prelp_to_pnnnn
