I need to make a vlookup function based on two unique IDs. So far the Internet has told me that a combined match index will do the trick. Unfortunately are my excels skills limiting me.
Basically I have 3 different tabs. In tab1 I have a col with dates and one with quantities. These are the cols I need to lookup. In tab2 I have dates and a supplier name, while Im in tab3 got quantity information and a supplier name.
So I wish to match the information in tab2 and tab3 with tab1 so I can see when a supplier delivered a given quantity.
