I would like to do the following mapping
ZLIFBANK -> E1LFBKM
BANKSCHL -> BANKN
BANKNR -> BANKN
I would like to map ZLIFBANK -> E1LFBKM only if the field BANKL isn't initial.
The problem at the moment is, if there are no values in the fields of the structure ZLIFBANK, the IDOC in the backend SAP has an empty structure in segment E1LFBKM.
Is there a possible to use a customer function?
