Hi Expert,
I want to chnage Vat code for IDOC basic type INVOIC01 . I found user exit EXIT_SAPLMRMH_012 but here I am not getting proper validating data.
So I found EXIT_SAPLMRMH_012 and EXIT_SAPLMRMH_014 . here I am modifying T_IDOC_DATA with new tax code. but at the end it is not replicating.
Regards,
Asing
