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

SAP Error Message - Details

• 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.

• What is the cause and solution for SAP error message DBMAN977 - No referential integrity set for filter on attribute &1 ?

  The SAP error message DBMAN977 indicates that there is no referential integrity set for a filter on a specific attribute in your database. This typically occurs in the context of database management and data modeling within SAP systems, particularly when working with data sources, InfoProviders, or queries.
  Cause:
  The error arises when:
  
  A filter is applied to an attribute that does not have a defined referential integrity relationship with other attributes or tables.
  The attribute in question is being used in a way that requires a relationship to be established, but such a relationship is missing or not properly configured.
  
  Solution:
  To resolve the DBMAN977 error, you can take the following steps:
  
  
  Check the Data Model:
  
  Review the data model to ensure that the attribute in question has the necessary relationships defined. This may involve checking the InfoObjects, InfoProviders, or any other relevant data structures.
  
  
  
  Define Referential Integrity:
  
  If the attribute is supposed to have referential integrity, you need to define it. This can be done in the data modeling tools within SAP (like SAP BW or SAP HANA).
  Ensure that the foreign key relationships are correctly set up between the tables or attributes involved.
  
  
  
  Adjust Filters:
  
  If the filter applied is not necessary or can be modified, consider adjusting or removing it to avoid the error.
  
  
  
  Data Source Configuration:
  
  If you are working with a data source, ensure that the data source is correctly configured and that all necessary attributes and relationships are included.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on setting up referential integrity for the type of data model you are working with.
  
  
  
  Testing:
  
  After making changes, test the query or data extraction process again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Referential Integrity: This is a database concept that ensures that relationships between tables remain consistent. For example, if a record in one table references a record in another table, referential integrity ensures that the referenced record exists.
  SAP BW: In SAP Business Warehouse (BW), referential integrity is crucial for ensuring that data is accurate and that queries return valid results.
  Data Modeling Tools: Familiarize yourself with the data modeling tools available in your SAP environment, as they provide functionalities to define and manage relationships between data elements.
