  • What causes this issue?

    The number of key fields in the check table is greater than the number
    of foreign key fields defined.

    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?

    Specify the foreign key completely. If you do not want to check all the
    key fields of the check table, you must set the 'generic' flag in the
    foreign key maintenance routine for the corresponding field.
    This state can also occur during transport and during a release upgrade
    if the key of the check table was shortened. Although the foreign key
    tables were adjusted, the old version of the check table could have
    been used during activation because of the order of activation.
    This state is automatically corrected as soon as the check table is
    activated.
