How To Fix L9300 - Error in background processing

L9300 - Overview

• Message type: E = Error

• Message class: L9 - Function Modules

• Message number: 300

• Message text: Error in background processing

What causes this issue?

After you have completed processing data on the screen, the system is
supposed to start background processing.
This processing may include:
Creating a <GL:transfer_order>transfer order</> (TO) immediately as the
result of a material document posting
Creating a material document as the result of processing a TO
Creating a TO immediately from a <GL:transfer_requirement>transfer
requirement</> during <GL:material_staging>staging</> for production
(PP)
Creating a TO immediately for a <GL:delivery>delivery</>
Normally, this background processing is not started until the document
that initiated it has been fully processed and posted and the blocking
entries have been removed. It is possible, however, that the blocking
entries may still exist.
Therefore, when background processing begins, the system sets another
"temporary" block to check whether blocking entries still exist. For
this activity, the "WAIT" parameter is set. This means that the system
waits for a certain time period to set the block in case the first
blocking attempt was not successful. You can set the length of this
waiting period in the system profiles.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If this error situation occurs regularly, increase the length of the
time period for the WAIT parameter in the system profiles.
