Selection from different tables

Hello Everyone,

I have a situation where I have 15 fields in the selection screen.

The selection is dependent on three or more tables.

First I have selected from two tables but if the user enters values in the selection screen then how to make the selection.

Tables dont have common fields between them. LIKP, LIPS, VTTK, VBUK and VEKP are the tables.

Can you guys guide me.

Thank you.
