## Tracking Inventory Levels

Hello everyone,

I'm having trouble figuring out how to calculate a running inventory level based on quantity of an item purchased and sold and few other events. In summary, each day purchases, sales, and other events are recorded per product. I got to the point where I created an inventory table with all available dates for the life of a product, a product ID, purchase price and then quantity that was purchased, sold, etc. each day.

Now I'm at a point where I need to create a calculated column that shows quantity of a product that is available in inventory on a given day. It's very simple to do in Excel, but I'm struggling to get the column created in QlikView script. Attached is the app and a sample spreadsheet that I'm working with. Quantity In Stock (Column J) is what I'm trying to create in script.

Does anyone know of a way to get that done?

Thanks,

Mikhail B.

## Re: Tracking Inventory Levels

Solved my own problem. I keep forgetting about Peek function. All that's need to be done here is a preceding load with an IF statement that references previous Quantity In Stock value:

 Inventory: LOAD *, If([Product ID] = Peek([Product ID]),      RangeSum([Quantity Change], Peek([Quantity In Stock])),      [Quantity Change])                                 as [Quantity In Stock]; LOAD Date,      [Product ID],      [Purchase Price],      [Quantity Purchased],      [Quantity Sold],      [Quantity Used],      [Quantity Given],      [Quantity Borrowed],      RangeSum([Quantity Purchased],                -[Quantity Sold],                -[Quantity Used],                -[Quantity Given],                -[Quantity Borrowed])                    as [Quantity Change] FROM [Source-Data\QlikView Community\Inventory.xlsx] (ooxml, embedded labels, table is Inventory);
