I am working on an in terface for upload of data in journal ledger(FB50)
Actually i need to validate a field which has been included in transaction FB50 as an enhancement based on customer need .
a function module was created as suggested in note 487722 earlier but now we require to validate that field(transaction type) as i am using this BAPI in an interface for journal ledger posting FB50 for data validation of the file data.
this field has been populated as a part of the extension parameter in the bapi -
field values for this field have been passed in the business transaction.
but i am not sure where to code the validation for this field .
could anybody suggest if we need to do it in include ZXACCU15 .
if so then how do we populate the values for the return parameter.
i am post ing document using IDOC and need to generate the for the errors generated.
it already shows for all the standard fields of the transaction.
Its a bit urgent,
