  The SAP error message AD093 indicates that there is a naming conflict in the system. Specifically, it means that the first seven characters of the name you are trying to use for a new object (such as a program, function module, or other development object) are identical to those of an existing object in the MC (Master Control) table. This is a safeguard to prevent naming collisions that could lead to confusion or errors in the system.
