Hi,
I have a trouble. Here is the table structure.
PERNR - personnal number
REINR - trip key
BELNR - Document No
Above three are composite keys. I am trying to add C_DOC which is a credit card document no as a another keys to this table.
I am trying PERNR, REINR,BELNR, C_DOC has a composite key. But I am getting this error.
Key is already defined.Field C_DOC cannot be in the key.
New or non-key field C_DOC is a key field now.
Please suggest how to include C_DOC as a composite key to this table.
Thanks.
