  • What causes this issue?

    You have changed the characteristic values of the order. The order is
    linked to a <DS:GLOS.3559911290FA5063E10000009B38F984>production
    process</> through these characteristic values. The order is in turn
    linked to a <DS:GLOS.3526B6F2AFAB52B9E10000009B38F974>product cost
    collector</> through this production process.
    You want the system to find a product cost collector that corresponds
    to these (changed) characteristic values.

    System Response

    The system does not allow the product cost collector to be changed for
    the following reasons:
    Costs from the order have already been posted to the product cost
    collector (based on the previous characteristic values).
    No product cost collector that corresponds to the (new) characteristic
    values can be found.

    How to fix this error?

    The costs for this order are still posted to the original product cost
    collector.

    Procedure for System Administrators

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