OL519 - Details

• The SAP error message OL519 indicates that there is a recursion issue when trying to reassign an object type in the system. This typically occurs in the context of object management, where the system detects that the reassignment would lead to a circular reference or recursion, which is not allowed.
  
  Cause:
  The error OL519 is usually caused by one of the following scenarios:
  
  
  Circular Reference: The object you are trying to reassign is already linked to another object in a way that would create a loop. For example, if Object A is assigned to Object B, and you try to reassign Object B back to Object A, it creates a recursion.
  
  
  Incorrect Object Relationships: The relationships between the objects may not be correctly defined, leading to a situation where the system cannot process the reassignment without encountering a loop.
  
  
  
  Configuration Issues: There may be issues in the configuration of the object types or their relationships
