Hi,

     We did a custom enhancement on LIS standard datasource: 2LIS_11_VAITM.  After doing such enhancement, data load to psa is getting failed with the following error message from BW

"

I have searched other threads of similar error message but couldn't find any solution there.

Could you please help us on how to resolve this problem?

Did you check in RSA3 whether your code is running properly or not.

It might be the issue with the datatype of the enhanced field or might be because of junk data.

Please check the same and also try to load data for one sales order or so.
