• What is the cause and solution for SAP error message M2790 - Function group & already exists! ?

  The SAP error message M2790 ("Function group & already exists!") typically occurs when you attempt to create a new function group in the SAP system with a name that already exists. Function groups are used in SAP to group related function modules together, and each function group must have a unique name.
  Cause:
  The error is caused by trying to create a function group with a name that is already in use. This can happen if:
  
  You are trying to create a function group with a name that has already been defined in the system.
  There may be a typo in the function group name you are trying to create.
  You are working in a development environment where the function group was created previously.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Function Groups:
  
  Use transaction code SE80 (Object Navigator) or SE37 (Function Builder) to search for the function group by name.
  If the function group already exists, you can either use it or modify it as needed.
  
  
  
  Choose a Different Name:
  
  If you need to create a new function group, choose a different name that does not conflict with existing function groups.
  
  
  
  Review Naming Conventions:
  
  Ensure that you are following the naming conventions for function groups in your organization. This may include prefixes or specific patterns that help avoid naming conflicts.
  
  
  
  Transport Requests:
  
  If you are working in a development environment and the function group was created in another system (like a quality or production system), ensure that you have the correct transport requests and that the function group is not being transported or modified by another developer.
  
  
  
  Check for Deletion:
  
  If you believe the function group should not exist, check if it was deleted in the system. You can use transaction SE80 to look for deleted objects.
