  The SAP error message RX112, which states "No changes are allowed in the left-hand tree," typically occurs in the context of the SAP GUI when users are trying to make changes in a transaction that involves a hierarchical structure, such as the SAP Easy Access menu or other tree structures.
  Cause:
  The error usually arises due to one of the following reasons:
  
  Authorization Issues: The user may not have the necessary authorizations to make changes in the specified area of the SAP system.
  System Configuration: The system may be configured to restrict changes in certain areas, especially in production environments.
  Transaction Mode: The transaction may be in display mode rather than edit mode, preventing any changes from being made.

  Solution:
  To resolve the RX112 error, you can try the following steps:
  
  
  Check Authorizations:

  Check for Locks:
  
  Use transaction codes like SM12 to check for locks on the object you are trying to modify. If another user has locked it, you may need to wait until they release the lock.
