DTW: Cannot insert the value NULL in column ‘Name’

Hello

I’ve a big DTW issue with the ContactEmployees on BusinessPartner. I hope someone can help me out.

I generated a new DTW sheet because we’ve UDF fields on ContactPersons.

Save the sheet as Text/ Tab delimited with three records.

After import I receive the error: Cannot insert the value NULL in column ‘Name’. Of course this field is filled by me. Also checked or UDF fields aer mandatory.

I’ve check the answers on the other post in the forum and the SAP notes but none has results.

Has someone experience / solutions for this issue?
