Inventory And Profit/Loss

I have a workbook that contains several worksheets. The 2 important sheets are Imports and Sales.

In reading the MS KB, the help screens and this forum, I found a way to create a pivot table from 2 sheets using Data>Pivot Table>Multiple Consolidation Ranges. While that PT will provide a basic inventory and profit picture, it only allows 4 selects.

When these products are imported there are several SKU's. What gums up the works is there are several vendors for the same SKU's. Each vendor has a different price. The selling price is constant so the profit made on each particular item varies.

I would like to be able to keep track of inventory by vendor as well as profit by vendor.

Using the Consolidation PT does not seem to work.

I also tried making one sheet to hold all the data. i.e. data showing imports and sales. However, each entry is driven by the date. So while item A was received on 1/1/07, it was not sold until 1/2/07. The necessary columns for imports are filled in while the columns for sales remain blank until it is their row entry indicating a particular sale. At which point all the columns regarding Imports are blank. I swear, looking at the data sheet with all those blanks (actually0's) is like looking at a mouth full of broken teeth. The resulting PT is also not attractive.

I can not imagine I am the first person to have this problem. How do others handle figuring inventory and profits when you have two sheets. Are Pivot Tables the wrong solution? What would be better?
