• What is the cause and solution for SAP error message /SAPAPO/MC01054 - Class & is being used in active objects - (limited changes only) ?

  The SAP error message /SAPAPO/MC01054 indicates that a class is being used in active objects, which restricts the ability to make certain changes to that class. This is a common issue in SAP Advanced Planning and Optimization (APO) when trying to modify or delete a class that is currently in use.
  Cause:
  The error occurs because the class you are trying to modify or delete is associated with active objects in the system. Active objects could include planning objects, master data, or any other entities that are currently being utilized in the system. SAP restricts changes to ensure data integrity and consistency.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Active Objects: Determine which active objects are using the class. You can do this by checking the relevant planning areas, master data, or any other components that might be linked to the class.
  
  
  Deactivate or Remove Dependencies: If possible, deactivate or remove the dependencies of the class from the active objects. This may involve:
  
  Changing the planning area settings.
  Modifying or deleting the master data that references the class.
  Ensuring that no active planning runs are using the class.
  
  
  
  Use Limited Changes: If you only need to make limited changes, consider using the "limited changes" option provided by SAP. This allows you to make certain modifications without fully deactivating the class.
  
  
  Check for Locks: Ensure that there are no locks on the objects that might prevent changes. You can use transaction codes like SM12 to check for locks.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific class and its usage to understand any additional constraints or requirements.
  
  
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance. They can provide guidance based on the specific context of your system.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/MC62 (for class management) and /SAPAPO/MC65 (for planning area settings).
  SAP Notes: Check for any SAP Notes that might address this specific error or provide additional context.
  System Documentation: Review your system's documentation for any customizations or configurations that might affect class usage.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to modify or delete the class as needed.
