Same Values unable to be inserted in SAP table

I have made two keys in the table in SAP, mandt and subject values of subject have to be repetitive. But I'm unable to insert same values. Error being shown is:

an entry already exists with the same key

This error persists even after I remove subject as the key. This may be a silly question, but I'm new to world of SAP.

Solution

  • The fact that those values are keys is the issue. You must use any other field that make them non-unique.

    I don't know your case but you can use another field, a sequence or a guid value.

    Hope it helps.
