Example: Stored procedure critical number

Set up your critical number in the Critical Numbers form.
- Choose a program name for your custom stored procedure.
  We recommend that you create a naming convention for your custom procedures so that they do not conflict with current or future procedures. For example, you can use a prefix that includes your company name.
- Choose the parameters you want to be able to set without changing the values in the code. Careful planning of parameter definitions can make the same program usable for multiple critical numbers you want to retrieve. For example, you can set a specific buyer's ID or make the same program run against three different warehouses.
- Keep in mind that you can override any and all settings on this form in your code.

Open your preferred code editor and create your custom stored procedure. The parameters of every critical number are the same. For example:


CREATE PROCEDURE [dbo].[SSSWBCanCoBookSp] (
  @KPINum    WBKPINumType
, @AsOfDate DateType

) AS

where SSSWBCanCoBookSp is the name of your procedure.

Write the logic to calculate your value and assign it to @Amount. The amount is returned to be displayed to the user.
To retrieve any parameters that you may have set up, you can call a standard function. It is dbo.WBGetParm. Pass in the critical number you are dealing with (@KPINum), and the parameter you want to retrieve. The parameter is looked for first in that specific critical number, and then in the general listing on the Critical Number Parameters form. To retrieve a parameter called "Acct" and set it into a variable in your stored procedure, you must follow use this example:

An example of past due order lines:
