• What is the cause and solution for SAP error message WN779 - The function group & does not exist ?

  The SAP error message WN779 indicates that the function group specified in the error message does not exist in the SAP system. This can occur for various reasons, such as a missing or incorrectly named function group, or issues with the transport of objects between different SAP systems.
  Cause:
  
  Non-existent Function Group: The function group you are trying to access or use has not been created or has been deleted.
  Incorrect Naming: There may be a typo or incorrect naming in the function group reference.
  Transport Issues: If the function group was recently transported from another system, it may not have been transported correctly or may not exist in the target system.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to access the function group, leading to the perception that it does not exist.
  
  Solution:

  Authorization Check:
  
  Ensure that the user has the necessary authorizations to access the function group. You may need to consult with your SAP security team to verify this.
