How To Fix SV326 - Function group is too big. Use another function group if possible.

SV326 - Overview

• Message type: E = Error

• Message class: SV - View Maintenance: Customize Messages

• Message number: 326

• Message text: Function group is too big. Use another function group if possible.

What causes this issue?

The function group already contains so many function modules that there
may not be enough memory available at run time for the extended table
maintenance. This causes termination.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Delete some views from the function group and put them in another,
possibly new, function group.
Note that your changes, e.g. maintenance screen modifications, are lost
when you delete. User-defined source code and user-defined interface
control information is not copied into the new function group.
Before a view can be created in anoter function group, it must be
deleted from the previous function group, and the associated entry must
be deleted from the table/view catalog.

  Solutions:
  
  Create a New Function Group: If possible, create a new function group to distribute the function modules. This is the most straightforward solution.
  Refactor Code: Review the existing function modules and see if you
