• What is the cause and solution for SAP error message /SAPAPO/MC01402 - Multiple classification: Existing class assignment remains unchanged ?

  The SAP error message /SAPAPO/MC01402 typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is an attempt to change the classification of a material or object that is already assigned to multiple classes. This error indicates that the existing class assignment will remain unchanged due to the constraints of the system.
  Cause:
  The error is generally caused by one of the following reasons:
  
  Multiple Class Assignments: The material or object is already assigned to multiple classes, and the system does not allow changes to the classification that would conflict with existing assignments.
  Inconsistent Data: There may be inconsistencies in the classification data that prevent the system from processing the changes.
  Authorization Issues: The user may not have the necessary authorizations to make changes to the classification of the material or object.

  Check for Inconsistencies:
  
  Ensure that there are no inconsistencies in the classification data. You can use transaction codes like CL01 (Create Class) or CL02 (Change Class) to verify and correct any issues.
