How To Fix UD705 - You modeled a loop in the generalizations; resolve the loop

SAP Error Message - Details

• Message type: E = Error

• Message class: UD - EDM - Enterprise Data Model

• Message number: 705

• Message text: You modeled a loop in the generalizations; resolve the loop

What causes this issue?

You generated a loop when modelling generalizations, i.e. you
encounter an entity type twice on the generalization path. Therefore
you cannot inherit attributes.

System Response

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?

Check you model and remove the loop.

• What is the cause and solution for SAP error message UD705 - You modeled a loop in the generalizations; resolve the loop ?

  The SAP error message UD705 indicates that there is a loop in the generalization hierarchy of your data model. This typically occurs in the context of SAP Business Warehouse (BW) or SAP HANA when you are working with data modeling, particularly when defining hierarchies or relationships between different entities.
  
  Cause:
  The loop in generalizations usually arises when:
  
  Circular References: There are circular references in the hierarchy where an entity indirectly refers back to itself through a series of relationships.
  Incorrect Hierarchy Definition: The hierarchy is not defined correctly, leading to multiple paths to the same node.
  Multiple Generalizations: There are multiple generalizations that create a loop, making it impossible for the system to determine a clear path for data aggregation or reporting.
  
  
  Solution:
  To resolve the UD705 error, you can take the following steps:
  
  
  Review the Hierarchy: Examine the generalization hierarchy to identify where the loop occurs. Look for entities that reference each other in a circular manner.
