How To Fix RSRV089 - Check foreign key relationship between fact and dimension tables

SAP Error Message - Details

• Message type: E = Error

• Message class: RSRV -

• Message number: 089

• Message text: Check foreign key relationship between fact and dimension tables

Description:
This elementary test checks the foreign key relationship between a fact
table and a dimensions table. It checks whether the dimension keys that
appear in the fact table in the column for the specified dimension are
the same keys that appear in the dimensions table (as key fields).
Note that there is no point in applying this test to the compressed
fact table of an InfoCube and its package dimensions, because all the
keys in the package dimension are set to the initial value zero in the
(compressed) fact table as a result of the compression process.
Parameters:
The test expects you to specify the following parameters: the name of
an InfoCube, the type of fact table (E or F table), and the name of the
dimension.

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

Repairs:
Repairs cannot be made. If you cannot eliminate this inconsistency
yourself, please send an error message to SAP.
