Use of Components from the Subcontract Order You can determine the following for the phase of a phase structure:
Whether the phase in the work order is to use components from the subcontract order
This includes subcontracting components, co-products, and the product from the subcontract order item. A subcontracting component is a component in the subcontract order with a positive requirement value. A co-product has a negative requirement value.
Whether the phase uses these components as input or output components
One option is available in which the phase copies the input/output classification from the subcontract order. Other options allow you to model the component flow more flexibly.
A phase can use the components from the subcontract order in addition to the components that you assigned directly to the phase in the phase structure. In particular, you can also assign no component at all to the phase in the phase structure, and just use the components from the subcontract order.
Note
If you use components from the production data structure (PDS) or from the production process model, you cannot use any components from the subcontract order.
The following options are available (see also the graphic below):
Do not use components from the subcontract order
With this option, the phase does not use any components from the subcontract order.
Assign subcontracting components, co-products, and product using the component assignment rule (option X)
With this option, the phase uses the subcontracting components as input components, and uses the co-products and product from the subcontract order item as output components. If you choose this option for several phases of the phase structure, the system assigns the components to the phases as follows:
The system assigns the subcontracting components as input components to the first phase for which you selected the option.
The system assigns the co-products and the product as output components to the last phase for which you selected the option.
If you would like a different assignment, you have to define a component assignment rule. In the component assignment rule , you assign the components to the phases for which you configured option X.
Use subcontracting components as input and output (option C)
With this option, the phase uses the subcontracting components as input and output components.
You cannot use a component assignment rule with this option.
Use product and co-products as input and output (option F)
With this option, the phase uses the following products as input and output components:
Product from the subcontract order item
Co-products
You cannot use a component assignment rule with this option.
Use subcontracting components as input, product and co-products as output (option S)
With this option, the phase uses the subcontracting components as input components and the following products as output components:
Product from the subcontract order item
Co-products
You cannot use a component assignment rule with this option.
Use subcontracting components as input (option I)
With this option, the phase uses the subcontracting components as input components.
You cannot use a component assignment rule with this option.
Use product and co-products as output (option O)
With this option, the phase uses the following products as output components:
Product from the subcontract order item
Co-products
You cannot use a component assignment rule with this option.
The following graphic displays the different options:

Within a phase structure, you can only combine the following options for the different phases:
You can combine the following options:
Do not use components from the subcontract order
Assign subcontracting components, co-products, and product using the component assignment rule (option X)
You can combine the following options for which you cannot use component assignment rules:
Use subcontracting components as input and output (option C)
Use product and co-products as input and output (option F)
Use subcontracting components as input, product and co-products as output (option S)
Use subcontracting components as input (option I)
Use product and co-products as output (option O)
You can use the following options in addition to or instead of the components that are assigned directly for a phase. When you configure the component assignment, note the following rules:
In the resulting work order, every phase must have at least one input component and one output component. If you use subcontracting components, the consistency check cannot check this rule because the components from the subcontract order are only known when the work order is created.
If you assign input or output components to a phase directly, you also have to assign the primary product to this phase or to another phase directly. This is the only way you can determine the quantity ratios between the components and the primary product.
