• Subcontracting
• Stock transfer

Features

The document type is used

• When generating purchase requisitions in the planning run
• When converting planned orders into purchase requisitions

• The system displays the document type from the MRP list or stock/requirements list in the detail screen of the purchase requisition. You have no control function in material requirements planning. The system only displays the information.
• The system always generates purchase requisitions for direct procurement with the document type NB for standard purchase order.You do not normally have to make entries for the document types in Customizing. If you have not defined a document type, the system will always generate purchase requisitions with the document type NB.
