R1147 - Details

• The SAP error message R1147 indicates that an application object has already been called in the current Logical Unit of Work (LUW). This typically occurs in scenarios where a function module or a method is trying to access or manipulate an object that has already been processed within the same transaction.
  
  Cause:
  
  Duplicate Calls: The most common cause is that the same application object (like a function module, method, or transaction) is being called multiple times within the same LUW.
  Incorrect Logic: There may be a logical error in the program where the same object is unintentionally invoked more than once.
  Concurrency Issues: If multiple processes are trying to access the same object simultaneously, it can lead to this error.
  
  
  Solution:
  
  Check for Duplicate Calls: Review the code to ensure that the application object is not being called multiple times within the same LUW. If it is, refactor the code to avoid this.
