    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).
