ABAP Date Conversion - DD.MM.YYYY to YYYYMMDD - SAP Function Module


There are two function modules available in SAP but don't get confused.

1. CONVERSION_EXIT_PDATE_INPUT
2. CONVERSION_EXIT_SDATE_INPUT

In SAP both function module shows to be doing the same thing but that's not the case.


 CONVERSION_EXIT_PDATE_INPUT

This FM should be used where there is a need to validate Date of Birth.

So this function module will no doubt convert the date from DD.MM.YYYY to YYYYMMDD, but only for past date.


CONVERSION_EXIT_PDATE_INPUT - Sample -1




CONVERSION_EXIT_SDATE_INPUT

This is the correct function module for date conversion from DD.MM.YYYY to YYYYMMDD.

CONVERSION_EXIT_SDATE_INPUT - Sample -1

CONVERSION_EXIT_SDATE_INPUT - Sample -2


Syntax: 

DATA: lv_dd_mm_yyyy(10) type c,
            lv_yyyymmdd type sy-datum.

CALL FUNCTION 'CONVERSION_EXIT_SDATE_INPUT'
        EXPORTING
          input  = lv_dd_mm_yyyy
        IMPORTING
          output = lv_yyyymmdd.
