• What is the cause and solution for SAP error message PMMO_BASIS032 - Subclass &1 must have instance generation 'Public' set in its properties ?

  The SAP error message PMMO_BASIS032 indicates that a subclass in the context of the SAP PM (Plant Maintenance) module is not configured correctly. Specifically, it states that the subclass must have the instance generation property set to 'Public'. This error typically arises when you are trying to create or modify a subclass in the SAP system, and the instance generation setting is not aligned with the requirements of the system.
  Cause:
  The primary cause of this error is that the subclass you are working with has not been configured to allow public instance generation. In SAP, instance generation refers to how instances of a class are created and managed. If the subclass is set to a different instance generation type (e.g., 'Private' or 'Protected'), it will not be accessible in the way that the system expects, leading to this error.
  Solution:
  To resolve this error, you need to change the instance generation property of the subclass to 'Public'. Here are the steps to do this:
  
  
  Access the Class Builder:
  
  Go to transaction code SE24 (Class Builder) in your SAP system.
  
  
  
  Find the Subclass:
  
  Enter the name of the subclass that is causing the error and click on the "Display" button.
  
  
  
  Edit the Class:
  
  Click on the "Change" button to edit the class.
  
  
  
  Check Properties:
  
  Navigate to the "Attributes" tab or section where you can see the properties of the class.
  
  
  
  Set Instance Generation:
  
  Look for the property related to "Instance Generation" and set it to 'Public'.
  
  
  
  Save Changes:
  
  After making the change, save the class.
  
  
  
  Test the Changes:
  
  Try to perform the action that previously triggered the error to ensure that it has been resolved.
