Planned independent requirements are created for the production plan. The material number of the "planning" material is entered. The expected total requirements for all variants are created. For information on how to create planned independent requirements, see Creatin g Planned Independent Requirements with Re ference or Creating Planned Independent Requirements Withou t a Reference .

The system finds requirements type VSEV because the strategy group has been set to 63. See the Table of Planning Strategy Assignments .

The requirements are passed on to MRP. The stock/requirements list (  Logistics Production MRP Evaluations Stock/reqmts list) displays the following information for the planning material.

Procurement requisitions are created in the MRP run (  Logistics Production MRP Total planning ). The stock/requirements list of the planning material displays the following information:

These procurement requisitions are the starting point for production or external procurement. Various possibilities exist for handling the actual production process. The following factors, however, are important for this strategy:

Stock is not taken into account.

The planned orders are not yet "real," because the variant product cannot be produced until after receipt of the sales order.Technically speaking, the planned orders have order type (VP).It is impossible to convert these (VP) planned orders into production orders, or to use them in a repetitive manufacturing environment.The Conversion field in the display of the planned order is not set, which indicates that it is not possible to produce this planned order.

The MRP run also creates procurement requisitions for the components. The stock/requirements list for the component ROH63A, for example, is as follows:

The main objective of this strategy has now been reached: procurement for the components has been triggered, even without sales orders, based on the sales forecast from Demand Management only. Procurement of the components can occur in a variety of ways. Here we are assuming that a goods receipt (for a purchase order, for example) takes place. The stock/requirements list for all components of the planning material displays the following information:

Stage 3: Sales Order and Allocation

A sales order for a variant material is entered

Suppose that, for this example, an order with a quantity of 90 pieces is entered with a required delivery date of today. This order can be confirmed after the first planned independent requirement date <reqdat1>, if :

The consumption parameters have been maintained correctly ( Consumption mode, Bwd consumption per., Fwd consumption per. ) in the planning material.

This date and the planned independent requirements can be found.

For more information, see Consumption Strategies and Logic .

After the sales order has been entered, the stock/requirements list of the variant material looks like this:

At component level, the requirement from the planning material has been switched to a requirement from the variant material ( SZ-63 in this example). The sum of the requirements stays the same.

Stage 4: Procurement After Sales

After a second planning run, the stock/requirements list of the variant material is as follows:

After creation and release of the production order (for the variant product) the stock/requirements situation remains the same. This means that the planned order is replaced by a production order.

Perform a Goods Receipt for the "variant" material, after production.Note the increase in available stock in the stock requirements list of the variant material.

Stage 5: Goods Issue for Delivery and Reduction of Planned Independent Requirements
