• What is the cause and solution for SAP error message SV659 - There are too many function modules in function group & ?

  The SAP error message SV659 indicates that there are too many function modules defined in a particular function group. This is a limitation within the SAP system, where a function group can only contain a certain number of function modules. When this limit is exceeded, the system generates this error message.
  Cause:
  The primary cause of this error is that the function group has reached its maximum limit of function modules. Each function group in SAP has a predefined limit on the number of function modules it can contain, and exceeding this limit will trigger the error.
  Solution:
  To resolve the SV659 error, you can consider the following solutions:
  
  
  Review Function Group Design:
  
  Analyze the function group to determine if it can be split into multiple function groups. If there are too many function modules, it may be beneficial to reorganize the code into smaller, more manageable function groups.
  
  
  
  Remove Unused Function Modules:
  
  Check for any function modules that are no longer in use or are obsolete. If you find any, consider deleting them to free up space within the function group.
  
  
  
  Refactor Code:
  
  If possible, refactor the code to combine related functionality into fewer function modules. This can help reduce the total number of function modules in the group.
  
  
  
  Create New Function Groups:
  
  If the function group is still needed but has reached its limit, you can create a new function group and move some of the function modules to the new group.
  
  
  
  Consult SAP Documentation:
  
  Review SAP documentation or notes related to function group limitations for any specific guidelines or recommendations.
  
  
  
  Contact SAP Support:
