Subcontracting is also possible in conjunction with sales order stocks and project stocks. The subcontracting orders are account-assigned to a sales order or a WBS element. Thus, the components are not transferred (using a transfer posting) to the "stock of material provided to vendor" but are directly withdrawn from the sales order stock or the project stock at the time of the goods receipt. The material manufactured is also posted to the sales order stock or to the project stock. The cost of subcontracting is then debited to the sales order or WBS element.

For components that are managed in sales order stock or project stock, you can define whether the components are to be withdrawn directly from each sales order/project stock or from the stock of material provided to vendor. You manage this via the dependent requirements indicator for individual customer requirements and collective requirements (MARC-SBDKZ).

You can maintain this indicator in the following places:

• in the MRP view of the material master record (MRP 4)

• in the explosion types for the BOM item (in Customizing for Production in the step Basic Data -> Bill of Material -> Item Data -> Define explosion types)

Configuring the explosion types has priority over the configuration in Inventory Management.

If the indicator is set at Collective requirements only (2), the materials are withdrawn from the stock of material provided to vendor. If this indicator is set any other way, the system withdraws materials from sales order stock or project stock.
