Diagnosis
The attribute &V2& was changed in batch &V3&.
The sender attribute &V2&, however, was sent in derivation (no. &V1&).
Changing the sender attribute &V2& does not guarantee that anotherderivation would be consistent with derivation &V1&.

System Response
The status of derivation no. &V1& is set to a statusthat indicates that the derivation is no longer up-to-date.

Procedure
Check the derivation and the values of the receiving batch.
Correct the receiving batch if necessary.
You can then reconvert the status of the derivation in the derivationmonitor.
