Create a custom code to upload data using idoc.
1. How to validate the data using lsmw - idoc -
When ever I upload the flat file data using lsmw idoc , it creates the same entry , thereby overwriting the previous entry. What I want is that whenever I execute the session it should give an error in case the same entry exists before.
2. Is there some other alternative as I have already tried direct/batch input and bapi and they both don't appear to solve my issue.
3. Can I create some custom code to upload the data using idoc?
