Restricting Range in Selection Option

SAP Restricting Range

Generally, we use NO INTERVALS keyword to restrict range for select option in Selection Screen. This seems to be fine, but if someone press Select Ranges tab, then user can still enter the range, which we don't want. 

To address this issue, we can use the FM SELECT_OPTIONS_RESTRICT, which does the job for us by removing the ranges tab and therefore completely restricting the range in Select Option.
