When is a purchase requisition typically created automatically?

A purchase requisition is typically created automatically when stock levels fall below minimum requirements. This is a crucial aspect of inventory management and procurement processes within SAP S/4HANA. The system continuously monitors inventory levels and, upon determining that the stock quantity has fallen below predefined thresholds, it triggers the creation of a purchase requisition. This automated process ensures that materials and goods are reordered in a timely manner, helping to avoid stockouts and ensuring that operations can continue without interruption.

Automatically generating purchase requisitions based on stock levels is part of the material requirements planning (MRP) functionality in SAP. MRP evaluates the demand and supply situation of materials, leading to efficient management of inventory and procurement processes.

The other scenarios provided do not typically result in automatic purchase requisition creation. Selecting an external vendor generally involves a more manual and decision-oriented process, while placing an order is a subsequent action that is initiated after a purchase requisition has already been created. Generating a forecast is more about predicting future demand rather than triggering immediate procurement actions, so it does not directly lead to the automatic creation of purchase requisitions.
