• What is the cause and solution for SAP error message MC364 - The function groups &Q, &0,...,& are already full ?

  The SAP error message MC364, which states "The function groups &Q, &0,...,& are already full," typically occurs when the system has reached the maximum number of function groups that can be created or utilized in a particular context. This can happen in various scenarios, such as during the creation of new function modules or when trying to add new functionality to existing ones.
  Cause:
  
  Function Group Limit: Each function group in SAP has a limit on the number of function modules it can contain. If this limit is reached, you will encounter this error.
  System Configuration: The system may be configured in a way that restricts the number of function groups or modules that can be created.
  Development Environment: In a development environment, if multiple developers are working on the same function group, it can lead to this error if not managed properly.
  
  Solution:
  
  Check Function Group Usage: Review the function groups that are currently in use. You can do this by using transaction SE80 (Object Navigator) or SE37 (Function Builder) to see the existing function groups and their contents.
  Delete Unused Function Modules: If there are function modules that are no longer needed, consider deleting them to free up space within the function group.
  Create a New Function Group: If the current function group is full, you may need to create a new function group to accommodate additional function modules. This can be done using transaction SE80 or SE37.
  Consult SAP Notes: Check for any relevant SAP Notes that may address this issue or provide additional guidance. You can search for notes related to function groups and their limitations.
  System Configuration Review: If you suspect that the system configuration is causing the issue, consult with your SAP Basis team to review the settings and limits for function groups.
