• What is the cause and solution for SAP error message 3G739 - Only one more module can be added to function group &1 ?

  The SAP error message 3G739 indicates that you have reached the limit for the number of modules that can be added to a function group in SAP. In SAP ABAP, a function group is a container for function modules, and there is a limit to how many function modules can be included in a single function group.
  Cause:
  The error occurs when you attempt to add more function modules to a function group that has already reached its maximum capacity. The limit is typically set to 100 function modules per function group.
  Solution:
  To resolve this error, you can consider the following options:
  
  
  Create a New Function Group: If you need to add more function modules, the most straightforward solution is to create a new function group. You can then create additional function modules in this new group.
  
  
  Review Existing Function Modules: Check if there are any function modules in the current function group that are no longer needed. If you find any that can be deleted or moved, you can free up space for new modules.
  
  
  Refactor Code: If possible, refactor your code to consolidate functionality into fewer function modules. This can help you stay within the limits of the function group.
  
  
  Use Function Module Groups: If your function modules are logically related, consider grouping them into a new function group that serves a specific purpose.
