Usage of Subqueries in Internal Table as Condition in SAP ABAP

Note that if you specify an OPTIONS parameter with parenthesis, it will show an error. When you use Where (itab)

In this case, itab has only one field with type C and shouldn’t be longer than 72 characters. “Itab” must be specified in parenthesis without any space between parenthesis and table name.

You should use the same condition in the internal table as a condition in ABAP source code.
