Loading of Master Data

Hi,

When i am loading master data in Quality i am getting an error like assign an LANGU field to the data source otherwise it will lead to a short dump. But i am loading data from a Sap Defined datasource. Why it was asking for a field. SAP as not given a field in the data souce.

Could u please refer me wheather i want to enhance a field LANGU to the data source is it compulsory.

Regards,

Mahesh.
