Maintaining Variant Item Number Rules
Use Variant Item Number Rule Maintenance to define how QAD Configurator assigns item numbers to new variant items. Define rules for each configurable item from which you intend to create variant items. The configurable items are items for which you run the questionnaire, and all lower level configurable items in the product structure. Variants of these lower-level items are created in the same process.
A variant item number rule can be a combination of the following elements:
Fixed: a string of characters that does not vary with variant item
Character: a separator between elements of the number, such as a hyphen (-)
Current Configurable Item: the number of the current configurable item
Master Configurable Item: the number of the top level configurable item
Field: QAD EA database element field name
Feature: a selected feature for the variant item
Alphanumeric Sequence: alphabetically sequenced character, incremented for each variant item.
Numeric Sequence: a sequential number, incremented for each variant item
Every component except alphanumeric sequence and numeric sequence can be used more than once in a rule, provided that the total length of the number does not exceed 18 character positions.

Variant Item Number Rule Maintenance
To edit a variant item number rule:
1 Specify a configurable item in the Configurable Item field.
2 Select from three different variant item number rules. Each Function option represents the point from which a variant item can be created: item (the Variant Product Structure/Routing Generator), sales quote, or sales order. Each configurable item can have up to three different variant item numbering rules.
3 To copy from an existing rule, click the Copy button. In the Copy Rule window, specify a configurable item and select a function option; then click OK. The system copies the selected rule to the current rule.
4 Edit the rule element list in the Rule Details pane.
To add an element to the list, select an element from the Element drop-down list and click OK. In the pop-up window, supply the value and parameters and click OK. You cannot add more than one numeric sequence and alphanumeric sequence element to a format.
