Message text: Source matrix and target matrix are identical
While trying to copy a matrix you have attempted to copy a matrix onto
itself which is redundantly reduntant.
Keep in mind that the key to matrix is the compensation modifier, the
table ID and the enddate, so changing just the beginning date will also
cause the error that the tables are the same.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Check your source and target matrices and change one or the other. Be
more careful next time, as such copy functions can often be dangerous.

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
