• Message class: RSUQ - SAP Query Connection for BW

• Message number: 105

• Message text: Fields from parallel branches of the structure used in functional area

What causes this issue?

The functional area is defined using a logical database. Not all the
fields selected in the functional area are in a single common path from
the nodes to the leaves of the tree. This means there are fields that
have been selected from the parallel branches of the tree.
This functional area cannot be used as a basis for an InfoSource.

• What is the cause and solution for SAP error message RSUQ105 - Fields from parallel branches of the structure used in functional area ?

  The SAP error message RSUQ105 typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the data flow in a query or when using a structure that has fields from parallel branches. This error indicates that there are fields from different branches of a structure that cannot be processed together in the functional area of the query.
  Cause:
  
  Parallel Branches: The error arises when the query attempts to use fields from different branches of a structure that are not compatible. This often happens when the data model has been designed with multiple hierarchies or branches that are not aligned correctly.
  Inconsistent Data Model: The data model may have inconsistencies, such as fields that are not properly defined or linked, leading to conflicts when the query is executed.
  Query Design: The design of the query may be attempting to pull data from multiple sources that are not meant to be combined, leading to this error.
  
  Solution:
  
  Review Query Design: Check the query design in the Query Designer. Ensure that you are not mixing fields from different branches of the structure that are not compatible. If necessary, separate the fields into different queries or use a different approach to combine the data.
  Adjust Data Model: If the data model is causing the issue, consider adjusting the structure to ensure that fields from different branches can be used together. This may involve redefining hierarchies or relationships in the data model.
  Use Key Figures: If applicable, use key figures that are designed to work across the branches instead of using individual fields that may cause conflicts.
  Check for Updates: Ensure that your SAP BW system is up to date with the latest patches and updates, as some issues may have been resolved in newer versions.
