• What is the cause and solution for SAP error message /SAPAPO/MC01350 - Change not possible; block fixed ?

  The SAP error message /SAPAPO/MC01350 Change not possible; block fixed typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a user attempts to make changes to a planning object (like a planning book or a key figure) that is currently locked or blocked for editing. This can happen for various reasons, such as:
  Causes:
  
  Locking Mechanism: The planning object is locked by another user or process. This can happen if another user is currently editing the same object or if a background job is running that locks the object.
  Planning Version: The planning version you are trying to edit may be set to "fixed" or "blocked" for changes, preventing any modifications.
  Authorization Issues: The user may not have the necessary authorizations to make changes to the planning object.
  System Configuration: Certain configurations in the system may prevent changes to specific planning objects during certain periods (e.g., during a planning cycle).
  
  Solutions:
  
  Check Locks: Use transaction code SM12 to check for any locks on the object. If you find that another user has locked the object, you may need to wait until they release the lock or contact them to coordinate.
  Review Planning Version Settings: Check the settings of the planning version you are working with. If it is set to "fixed," you may need to change it to allow modifications. This can typically be done in the planning version settings in the APO system.
  User Authorizations: Ensure that you have the necessary authorizations to make changes to the planning object. You may need to contact your system administrator to verify your permissions.
  System Configuration: Review any system configurations that may be preventing changes. This may involve checking with your APO configuration team to understand if there are any restrictions in place.
  Wait for Background Jobs: If a background job is running that locks the object, you may need to wait for it to complete before making changes.
  
  Related Information:
