• What is the cause and solution for SAP error message M2141 - Different characteristic sequence in definition and generated structure ?

  The SAP error message M2141, which states "Different characteristic sequence in definition and generated structure," typically occurs in the context of SAP's Material Management (MM) module, particularly when dealing with characteristics and class types in classification.
  Cause:
  This error arises when there is a mismatch between the sequence of characteristics defined in a class and the sequence of characteristics in the generated structure. This can happen due to:
  
  Changes in Characteristic Order: If the order of characteristics in the class definition has been changed after the structure was generated, it can lead to this error.
  Inconsistent Data: If there are inconsistencies in the data model or if the characteristics have been modified without regenerating the structure.
  Multiple Class Types: If you are working with multiple class types and there is a mismatch in the characteristic sequence across these classes.
  
  Solution:
  To resolve the M2141 error, you can follow these steps:
  
  
  Check Characteristic Sequence:
  
  Go to the class definition in the SAP system and verify the order of the characteristics.
  Compare this with the generated structure to identify any discrepancies.
  
  
  
  Regenerate the Structure:
  
  If you have made changes to the characteristics, you may need to regenerate the structure. This can typically be done through the transaction code CL02 (Change Class) or CL03 (Display Class).
  After making sure the characteristic order is correct, regenerate the structure by using the appropriate function in the class maintenance screen.
  
  
  
  Consistency Check:
  
  Perform a consistency check on the class and its characteristics to ensure that there are no other underlying issues.
  You can use transaction CL20 (Class Management) to check for inconsistencies.
  
  
  
  Review Documentation:
  
  Review any documentation or change logs to understand if any recent changes might have led to this issue.
