  • What causes this issue?

    In an allocation table was generated for a promotion item, the sources
    of supply for the item cannot be changed.
    The sources of supply assigned in the promotion are used in the
    allocation table when data is stored. A subsequent change to the
    sources of supply would lead to inconsistencies in the promotion. As a
    result, the system does not permit you to change this data once
    allocation tables have been activated/generated.

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