Allow only a possible set of values to choose from while setting value in SAP ABAP
If you need to place a restriction as you said, you can go ahead with using predefined domains on the column or text field.
Select Table Field -> Data Element -> Specify Domain
While specifying the domain you can set the permissible set of values which you want the table field to be set.
However please don’t consider as a constraint that we place in database tables, the domain login can still be broken through code.
