USMD1046 - Details

• The SAP error message USMD1046 indicates that there is a recursive relationship defined in the data model for a specific entity type. This means that the entity type is trying to reference itself in a way that creates a loop, which is not allowed in the data model design.
  
  Cause:
  The error typically arises when:
  
  An entity type is defined to have a relationship with itself, leading to a recursive structure.
  The relationship is not properly defined or is incorrectly configured, causing the system to detect a loop.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Data Model: Check the data model configuration for the specified entity type. Look for any relationships that point back to the same entity type.
  
  
  Modify Relationships: If a recursive relationship is not intended, modify the relationship to point to a different entity type or remove the recursive reference.
  
  
  Use Hierarchical Structures: If the recursive relationship is necessary (for
