• What is the cause and solution for SAP error message SV651 - Dynpro numbers are assigned twice in function group &. ?

  The SAP error message SV651 indicates that there are duplicate Dynpro (dynamic program) numbers assigned within a function group. This typically occurs during the development of SAP programs, particularly when creating or modifying screens in the Screen Painter.
  Cause:
  The error arises when:
  
  Two or more screens within the same function group are assigned the same Dynpro number.
  A screen number is reused or incorrectly referenced in the function group.
  
  Solution:
  To resolve the SV651 error, follow these steps:
  
  
  Identify Duplicate Dynpro Numbers:
  
  Open the function group in the ABAP Workbench (transaction SE80).
  Navigate to the "Screens" section and list all the screens.
  Check the Dynpro numbers assigned to each screen and identify any duplicates.
  
  
  
  Change Dynpro Numbers:
  
  For any screens that have duplicate Dynpro numbers, change the Dynpro number of one of the screens to a unique number.
  Ensure that the new Dynpro number does not conflict with existing numbers in the function group.
  
  
  
  Adjust References:
  
  If you change a Dynpro number, make sure to update any references to that screen in your ABAP code (e.g., in PBO, PAI modules).
  
  
  
  Activate the Function Group:
  
  After making the changes, activate the function group to ensure that the changes take effect.
  
  
  
  Test the Changes:
  
  Execute the program or transaction that uses the function group to verify that the error has been resolved.
