System Response

The derivation is assigned with the status 'Carried out with error'. If
the derivation is static, it is saved anyway, but the receiving batch
or its class characteristics are not changed.

How to fix this error?

Check that the batch where-used list is complete:
Have all batches been assigned in the orders?
Have the goods receipts and goods issues been posted?
Check also that the condition records for the sending batches have been
created correctly.
If the derivation is static, repeat it if necessary or correct the
derived values in the receiving batch manually.
