What causes this issue?

You have entered a name-plant combination for the
<DS:GLOS.3608C3DABA271348E10000009B38F91F>MPN MRP Set</> that already
exists in this <DS:GLOS.3607AFB8AECD4ABAE10000009B38F9B8>FFF class</>.

System Response

The existing MPN MRP set is usually copied and the remaining materials
in the FFF class completed. However, this completion only takes place
if the materials have been maintained in the plant and MRP area that
have been entered. No further materials of the FFF class could be
determined since these requirements have either not been fulfilled or a
complete MPN MRP set already exists for this plant and MRP area.
