  Duplicate Posting: The most common cause of this error is that the cash deposit request has already been processed and posted to the system. This can happen if:
  
  The user inadvertently tries to post the same request multiple times.
  There is a system or user error that leads to the same request being submitted again.
  
  
  
  System Configuration: In some cases, the system configuration or customizations may lead to unexpected behavior, causing the system to think a request is still pending when it has already been processed.
  
  
  Solution:
  
  
  Check Existing Requests: 
  
  Verify if the cash deposit request has already been posted by checking the relevant transaction logs or reports in the system. You can use transaction codes like FBL5N (Customer Line Item Display) or FBL1N (Vendor Line Item Display) to see if the request exists.
