I changed the configuration names of several assemblyconfigurations used in a drawing. Now each time the drawing is openthe following message is desplayed.

The following component configurations could not be
found.
0308.81 and 0346.81-2 : 0343.81 (CONVEX-SQUARE CORE)
0308.81 and 0346.81-1 : ???????? (CREATERED-ROUND
CORE)
0308.81 and 0346.81-1 : 0353.81 (FLAT-ROUND CORE)
0308.81 and 0346.81-2 : ???????? (CREATERED-SQUARE
CORE)
0308.81 and 0346.81-1 : 0343.81 (Convex-Round Core)
0308.81 and 0346.81-2 : 0353.81 (FLAT-SQUARE CORE)
If the configuration was renamed the same configuration will
be used,
otherwise the last active configuration will be substituted in
each instance.

The drawing opens with no problem and is correct. But this messagekeeps reapearing each time the drawing is opened? How do I get ridof it?

TIA
