Maintaining Variant Planning Item Rules
Use Variant Planning Item Rule Maintenance to define variant planning item selection rules for non-kit configurable items. Variant planning items are used to consume forecast when confirmed sales orders are created for variant items. For configurable items that are physical or phantom kits, when you generate variant items from them, the system adds components of their variant items to the mrp_det table so that they also consume forecasts upon sales order confirm.
When you create a variant item by either creating a new configuration or modifying an existing one, the system runs the variant planning item rule to add the variant item to the product structure of the planning item as a component with the following values:
Structure Type = “P” (planning)
Forecast Percent = zero to prevent MRP from generating planned orders for the components of the variant item from the forecast of the planning item.
Quantity Per = 1
As Structure Type is P, the system consumes the forecast of the planning item with the variant item order quantity on the sales order line.
When the variant is put on a sales order line and confirmed, the forecast of the planning item, if set up, is consumed by the variant order quantity.
For a multi-level product structure, there can be multiple configurable items with their own planning items and selection rules.
1 Specify an existing configurable item and press Enter. The item cannot be a physical or phantom kit. The system validates the item number and displays an error message when:
The item does not exist.
The item is not a configurable item.
The configurable item is a physical or phantom kit.
2 Click the New icon to create a planning item and define selection rule for it. The selection rule in Variant Planning Item Rule Maintenance is optional and if it is left blank, the system always adds variant items to the planning bill of the specified planning item.
To edit a selection rule:
You can either manually type the rule by directly typing the statements in the Rule box or use the Rule Assistant to assist you in the process. See Using the Rule Assistant.
Click Check Syntax to validate the rule syntax. If syntax errors are found, error messages appear. The Status becomes Failed.
Click Save to save the rule. On saving the rule, the system performs a syntax check on the rule. If syntax errors are found, error messages display.
