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.
