How To Fix DI803 - Join condition for secondary table & conflicts with the hierarchy

SAP Error Message - Details

• Message type: E = Error

• Message class: DI - Dictionary messages: Indexes

• Message number: 803

• Message text: Join condition for secondary table & conflicts with the hierarchy

What causes this issue?

Each secondary table of a lock object must be connected to a base table
above it in the hierarchy with a join condition. This join condition
must be implemented via a foreign key. This foreign key must have the
secondary table as foreign key table and the base table higher in the
hierarchy as check table. The following must be true for all foreign
key fields of this foreign key relationship which are in base table:
the relevant base tables must be below the test tables in the
hierarchy.
This requirement is not met by the join condition named.

System Response

The action is terminated.

How to fix this error?

Build the hierarchy of the lock object correctly. Observe the

• What is the cause and solution for SAP error message DI803 - Join condition for secondary table & conflicts with the hierarchy ?

  The SAP error message DI803 indicates that there is a conflict in the join condition for a secondary table in a data source, particularly when dealing with hierarchies. This error typically arises in the context of data extraction or reporting, especially when using SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  
  Join Condition Conflict: The error occurs when the join condition defined for a secondary table conflicts with the hierarchy defined in the primary table. This can happen if the join keys do not align properly with the hierarchy structure.
  Hierarchy Structure: If the hierarchy is not properly defined or if the data in the secondary table does not match the expected structure of the hierarchy, it can lead to this error.
  Data Inconsistency: Inconsistent data between the primary and secondary tables can also trigger this error, especially if the secondary table contains values that do not exist in the hierarchy of the primary table.
  
  Solution:
  
  Review Join Conditions: Check the join conditions defined for the secondary table. Ensure that they are correctly aligned with the hierarchy of the primary table.
  Validate Hierarchy: Ensure that the hierarchy is correctly defined and that all necessary nodes and relationships are present. If there are missing nodes or incorrect relationships, update the hierarchy accordingly.
  Data Consistency Check: Perform a data consistency check between the primary and secondary tables. Ensure that the data in the secondary table matches the expected values in the hierarchy of the primary table.
  Adjust Data Model: If necessary, adjust the data model to ensure that the join conditions and hierarchy are compatible. This may involve modifying the data source or the way data is extracted.
  Testing: After making changes, test the data extraction or reporting process again to ensure that the error is resolved.
