When I am trying to create new BP it is throwing an error message that
" Grouping ZEM has external number assignment, enter a number "
and when i am trying to see the Error information, it is showing that
Message no. R1091
The business partner needs a key to identify it. This key was not specified.
The system issues an error message.
Enter a key in the dialog. If it is a background process or an XML message process, contact your system administrator.
So can any one Explain it what is this Issue?
