  The SAP error message I4647, which states "Call transaction &1, do not display screen, new internal session," typically occurs when there is an issue with the way a transaction is being called in an ABAP program or a custom report. This error is related to the use of the CALL TRANSACTION statement in ABAP.
  Cause:
  
  Incorrect Parameters: The parameters passed to the CALL TRANSACTION statement may not be set correctly. Specifically, the USING clause may not be properly defined.
  Session Management: The error can occur if the system is trying to open a new session but is unable to do so due to session management settings or limitations.
  Transaction Not Allowed: The transaction being called may not be allowed to run in the background or in a new session.
  Authorization Issues: The user may not have the necessary authorizations to execute the transaction in the specified mode.
  
  Solution:
  
  
  Check the CALL TRANSACTION Syntax: Ensure that the syntax of the CALL TRANSACTION statement is correct. For example:
  CALL TRANSACTION 'transaction_code' USING it_data.

  Use the Correct Mode: If you want to suppress the screen display, ensure you are using the MODE parameter correctly. For example:
  CALL TRANSACTION 'transaction_code' USING it_data MODE 'N'.
  The 'N' mode indicates that the transaction should run in the background without displaying the screen.
  
  
  Check User Authorizations: Verify that the user executing the transaction has the necessary authorizations to run the transaction in the specified mode.
  
  
  Review Session Settings: Check the system settings related to session management. If there are restrictions on the number of sessions a user can open, this may need to be adjusted.
