Future change records for background processing exist for order &

What causes this issue?

There are still future change records from the confirmation processes
(automatic goods receipt, backflushing, actual cost determination) for
the confirmation that you want to delete or the order you want to
change. Therefore, the action you have planned cannot be executed.
To execute the action you first have to post the future change records.

How to fix this error?

To post future change records you have the following options:
Dispatch a background job (program CORUPROC).
Process the future change records manually.
