Diagnosis
No intervals exist for number range object/subobject & &
System Response
You attempted to edit intervals for a number range object with groups (type 2, 3, 5, 6, 7, or 8). This is not possible if no intervals exist yet for this object (restricted to subobjects for types 5, 6, 7, and 8).
Procedure
You can only create intervals for number range objects from group maintenance (Maintain Groups --> Create).
SOLUTION :
STEP 1: Click on Change Group
STEP 2: Click on Create Group
STEP 3: Provide the Group Name and Number Range Interval and SAVE.
Result:
