Where to delete the Variant assignment to a user for KO04 transaction

Hi,

We enhanced the table AUFK to have one new field in place of one additional data. The data type is a different compared to the standard one.

After this , one of the user is getting error that the variant "ABC" has incorrect field data type. I deleted the variant "ABC". After that the system gives error for that user in tcode KO04, that the variant "ABC" does not exist.

I created a new variant with the same name "ABC" in the program "RKOSEL00".

Even though the program has the variant "ABC", the user is getting the same error that "The variant ABC does not exist".

Where to delete the assignment between the User and variant.

Some users who does not use the old default variant are not affected.

Regards
