The batch input program is based on the recording, it is clear. However I am not sure on which fields to code at the code side.
SAPMMPKR 0091 X
SAPMMPKR 0093 X
BDC_SUBSCR SAPMMPKR 0815INCLUDE8XX
Such a recording which fields are to be coded?
PKHD-NKDYN,BDC_CURSOR, BDC_OKCODE are required to code?
In fact what is the thumb of rule in bdc?
