• What is the cause and solution for SAP error message ME181 - Please enter the same class for all release groups ?

  The SAP error message ME181, which states "Please enter the same class for all release groups," typically occurs in the context of creating or modifying release strategies for purchase requisitions or purchase orders. This error indicates that there is a mismatch in the classification of the release groups defined in the release strategy.
  Cause:
  The error is caused by the following reasons:
  
  Inconsistent Class Assignment: The release groups in the release strategy are assigned to different classes. Each release group must belong to the same class for the system to process the release strategy correctly.
  Configuration Issues: There may be a misconfiguration in the release strategy settings in the customizing settings of SAP.
  
  Solution:
  To resolve the ME181 error, you can follow these steps:
  
  
  Check Release Strategy Configuration:
  
  Go to the transaction code SPRO (SAP Project Reference Object).
  Navigate to Materials Management > Purchasing > Purchase Order > Release Procedure > Define Release Procedure for Purchase Orders.
  Review the release strategies defined and ensure that all release groups are assigned to the same class.
  
  
  
  Verify Class Assignment:
  
  Check the classification of the release groups. You can do this by going to the transaction code CL02 (Change Class) and reviewing the classes assigned to each release group.
  Ensure that all release groups in the strategy are assigned to the same class.
  
  
  
  Adjust Release Groups:
  
  If you find that the release groups are assigned to different classes, you will need to either change the class of the release groups to match or create a new release strategy that uses consistent classes.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the release strategy again to ensure that the error no longer occurs.
  
  
  
  Related Information:
