  A custom enhancement or process expects this BAdI to be implemented.
  
  
  
  
  Solution
  
  
  Check if the BAdI is implemented:
  
  Go to transaction SE18 (BAdI Builder).
  Enter POS_EX_REC as the BAdI name.
  Check if there is any active implementation under the "Implementations" tab.
  
  
  
  Create an implementation if none exists:
  
  If no implementation exists, create a new one:
  
  Click on "Create Implementation".
  Provide a name and description.
  Implement the required methods as per your business requirements.
  Activate the implementation.
  
  
  
  
  
  Activate existing implementation:
