This process describes how you determine, when materials are to be made available in your production process.
The following data already exists in the system:
According to the item category of the assigned components you make further decisions about their processing (for example, backflushing of stock items).
You can assign a routing material components from several BOMs or alternative BOMs, by repeating this process. In this case when you create a production order, you select the BOM and thus which material components are to be assigned in the production order. The system can do this automatically, depending on the settings
Material components in a BOM that are not assigned to an operation in the routing are automatically assigned to the first operation when you create a production order.
If you have assigned a phantom assembly to an operation in a routing, the system automatically assigns all of the material components in the phantom assembly to the same operation as the phantom assembly when you create a production order.
If you have assigned individual material components from the phantom assembly to various operations without also allocating the phantom assembly, the system assigns the material components that have not been assigned and the phantom assembly to the beginning of the first operation when you create a production order.
