How do I Use Stock Formulae?

Summary
This article explains the stock calculation formulae used in Platinum and how to configure them.
More Information
When items are added to a Stock Invoice or Stock Sales Order the system can use a formula to determine if the item's stock level is within certain limits.
If you are using the Platinum Web Shop, you can also use a formula to choose what to display when a real time stock check is carried out.
The Reordering option can calculate Reorder and Maximum levels, what needs to be ordered and the quantity to order based on formula.

Applying Formula
Insufficient Stock
When an item is added to a stock invoice in Invoicing and Customer Orders and/or a sales Order in Sales Order Processing the system can perform a calculation to determine if the stock level is within the required limits. To configure this formula :
Go to " Reports & Settings Maintenance Options System Administrator Platinum Settings" and search for 'insuf stock'.
 | Each module has it's own setting. |
- Select the relevant module: Stock Control or Sales Order Processing.
- Select "Insufficient stock formula" and click [Edit].
- Enter the formula code or press <Ctrl+F1> to select from a list of available formula.
A suggested formula to use is 'NOSTK' 'S+O-A-Q1<0' This will take account of the Current Stock, plus the quantity on Purchase Orders, less quantity on Sales Orders, less the quantity on the current sale and if this is less than 0 you will be shown a warning.
Calculating Reorder and Maximum Levels
- See How do I Set Maximum and Reorder levels on Stock? to explain how to calculate levels using a formula.
- See An In Depth Guide to Reordering to explain how to reorder stock and how to calculate Reorder and Maximum Levels using formula.
You may also apply specific formula to individual stock items.
- Go to " Stock Control Add or Edit Stock Items"
- Either enter in the stock code if you know it or search for the item.
- Click on the [Depots] tab.
- In the "Max Formula" and/or "Min Formula" enter the code of your formula to calculate the Maximum and Reorder Levels for this specific item. If this field is left blank the system will use the default formula.
