• What is the cause and solution for SAP error message /SAPAPO/MC01307 - Check the class and char. definition in the OLTP and planning system ?

  The SAP error message /SAPAPO/MC01307 typically indicates an issue related to the characteristics and class definitions in the SAP Advanced Planning and Optimization (APO) system. This error often arises when there is a mismatch or inconsistency between the definitions in the OLTP (Online Transaction Processing) system and the APO system.
  Cause:
  
  Mismatch in Class Definitions: The characteristics or classes defined in the OLTP system do not match those in the APO system. This can happen if changes were made in one system but not replicated in the other.
  Missing Characteristics: The characteristics that are expected in the APO system may not exist in the OLTP system or vice versa.
  Inconsistent Data: There may be inconsistencies in the data related to the characteristics or classes, such as incorrect data types or missing values.
  Transport Issues: If changes were transported from one system to another, there may have been issues during the transport process that led to incomplete or incorrect data.
  
  Solution:
  
  
  Check Class and Characteristic Definitions:
  
  Go to the OLTP system and check the class and characteristic definitions. Ensure that they are correctly defined and match what is expected in the APO system.
  Use transaction codes like CL02 (Change Class) and CT04 (Change Characteristic) to review the definitions.
  
  
  
  Synchronize Definitions:
  
  If you find discrepancies, update the definitions in either the OLTP or APO system to ensure they match.
  If changes were made in the OLTP system, ensure they are transported to the APO system correctly.
  
  
  
  Check Transport Logs:
  
  If the issue arose after a transport, check the transport logs for any errors or warnings that might indicate what went wrong during the transport process.
  
  
  
  Recreate Characteristics:
  
  In some cases, it may be necessary to delete and recreate the characteristics or classes in the APO system to ensure they are correctly aligned with the OLTP system.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to this error message for any specific guidance or patches that may address the issue.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the error no longer occurs and that the system behaves as expected.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CL02, CT04, SCC1 (for client copy), and SCC3 (for transport logs).
  SAP Notes: Check SAP Notes for any known issues or fixes related to this error message.
  APO Configuration: Ensure that the APO configuration is correctly set up to handle the characteristics and classes as defined in the OLTP system.
