The command for SP2 places the string into SP1 field. SP2 should be separate and has a "+" to the right of it/usually timeshares with ac_typ but it can differ from site to site. Here is an example of what SP2 should look like when displayed in data tag:
VICE1
ILS+B737
I tested some more. It appears if I enter MULTI FUNC, Y,+ABC that is does go to SP2 but missing the +at the end. If I do implied +ABC, slew and click, it goes to SP1.
