How To Fix JIT00450 - Error during backflush; Note messages

SAP Error Message - Details

• Message type: E = Error

• Message class: JIT00 - JIT: Messages for JIT Process

• Message number: 450

• Message text: Error during backflush; Note messages

What causes this issue?

The confirmation of call components within repetitive manufacturing has
failed.

System Response

The confirmation has not been carried out.

How to fix this error?

Please check all settings that are necessary to carry out the
repetitive manufacturing backflush (see the relevant documentation). If
problems occur, you are recommended to carry out the backflush in the
foreground as a test, using the relevant repetitive manufacturing
transactions, in order to be able to recognize errors better. In
addition, the JIT basic data must be maintained correspondingly (JIT
customer, JIT components group, JIT material). In the JIT material the
backflush indicator must be set for the materials to be backflushed
(manual maintenance with transaction JITL). It is also possible that
you cannot backflush temporarily because of access conflicts. Please
try again later. If the material is not confirmed in the sequenced JIT
call process, then please delete the backflush indicator in the
sequenced JIT call material data (transaction JITL).
