What causes this issue?

The confirmation processes "autom. GR", "backflushing" and "actual cost
determination" can be executed asynchronously from the confirmation
online transaction in a background job.
Processing in a background job can take place in parallel, that is,
several portions of the work list are processed at the same time in
separate tasks.
If there are problems when starting such a task then this message is
sent. In addition, you can find out from the job log which task
(sequence number) with what size (size of the portion to be processed)
hit a problem.
