Default Inventory - 03-08-2007 , 01:46 PM






Hello,

A friend of mine who has a clothing shop for children asked me to write
an application for him which should allow him to track his inventory.

I have a Purchase Orders file (with a line items file) and a Sales
Orders file (with a line items file).

What is the best way to calculate stock? The easiest way to do this is
through the line items files and calculate the sum of quantities
purchased an quantities sold for each item.

Won't this slow down the application? Is there a better way to do this?

Thank you in advance,
Kind regards,
Hans

Yes, it will. I wouldn't advise setting it up with live calculations.

I would use scripts that perform functions like "Mark item received"
or "Mark PO received" and "Mark Sales Order Shipped" such that they
perform the correct additions and subtractions to your inventory
records which will have fields for "quantity on hand" "quantity
reserved" "quantity on order" etc.

Yep, a scripts approach is much better.

Even if you've got a fast computer, eventually trying to calculate
sales and additions on the fly is going to get slower and slower as
more records are added.

Using a script means you can avoid this and it alos makes it easier to
"archive off" old sales records no longer needed without affecting the
stock amounts.

Thanks for your help. Your answers somehow confirmed what I thought
would be the best solution. More work, but less trouble later on ...
