That is not possible with a "Derived from Table" input parameter. But you can reach your goal using an input parameter of type "Derived from Procedure/Scalar Function" (available since SPS10) (Create Input Parameters - SAP HANA Modeling Guide - SAP Library). The procedure or scalar function can have an input parameter to which another input parameter can be mapped in the view mapping section. Within the procedure or function you can then determine the relevant value out of your table depending on the other input parameter value.
