You can plan sales, production, purchases, and assembly (disassembly) by pegged demand sources. A pegged demand source ensures connection between plans and orders to fulfill these plans and allows you to control fulfillment of certain orders.
Plan generation by pegged demand sources is available only within the scenario for which planning by assignments is enabled. In the plans, you can specify any pegged objects (orders or lines of business) as an assignment value.
The following methods are used to specify assignments: for the whole document or line by line. The methods are defined in the card of the plan profile within which the plan is generated. Preliminarily, details by assignment are determined in the scenario.
Generation of a single plan by several pegged demand sources is available within the plan profile for which the Joint plan by assignments details are set. With such details, you can specify an assignment in each plan line.
You can specify pegged objects in plans using the following methods:
- Using formula (with filter by assignment from a plan header).
- By sources.
To filter data by a pegged demand source specified in the plan, use operands marked with * (the Edit formula form, the Operands section).

You can also plan semi-finished products and materials by pegged manufactured products. The source of pegged manufactured products is inherited by plans if the Provide on pegging basis method of receiving material is specified in the BOR for the semi-finished product or if the Pegged purchase/sale check box is selected in the product details.
Planning by pegged demands allows you to create orders to fulfill these pegged demands.
Analysis of inventory planning by assignments
To estimate and analyze pegged object inventory, use planning reports generated within the scenario for which planning by assignment is enabled (Budgeting and planning – Budgeting and planning reports – Inventory planning). In that case, the Assignment dimension will be available in planning reports.

If plans are generated by pegged objects, sources of pegged demand for semi-finished products and materials are displayed in context reports of production plans: Demand for semi-finished products and Demand for materials. You can get details of pegged manufactured products from reports on planned demand for materials and semi-finished products.
