CL350 - Details

• The SAP error message CL350 indicates that there is a recursive class hierarchy in the classification system. This means that a class is indirectly or directly referencing itself, which creates an inconsistency in the data structure. This can lead to issues in classification and data integrity within the SAP system.
  
  Cause:
  
  Circular References: A class may be assigned as a subclass of itself, either directly or through a chain of subclasses. For example, if Class A is a subclass of Class B, and Class B is a subclass of Class A, this creates a circular reference.
  Incorrect Class Assignments: During the creation or modification of class hierarchies, incorrect assignments may have been made, leading to recursive relationships.
  Data Migration Issues: If data has been migrated from another system or if there have been bulk changes made to class hierarchies, this could inadvertently create recursive relationships.
  
  
  Solution:
  
  Identify the Recursive Class: Use transaction codes like CL02 (Change
