How To Fix DBMAN977 - No referential integrity set for filter on attribute &1

DBMAN977 - Overview

• Message type: E = Error

• Message class: DBMAN - Data Manager Message Class

• Message number: 977

• Message text: No referential integrity set for filter on attribute &1

What causes this issue?

Currently, it cannot be guaranteed that master data exists for all
characteristic values of the InfoProvider to be read. Referential
Integrity is turned off for the attribute-carrying characteristic.
There is a restriction on a navigation attribute of the listed
characteristic in the query. This filters all characteristic values of
the master-data bearing characteristic for which there is not yet master
data out of the result.
For performance reasons, this filtering is unavoidable.

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?

In case of doubt, find other restrictions directly on the characteristic
values of the characteristics contained in the InfoProvider.
