What controls the field selection of purchase requisitions?

The field selection of purchase requisitions is primarily controlled by the document type. In SAP, the document type acts as a classification tool for different transactions, defining how they behave and what fields are available for input. For purchase requisitions, the document type determines which fields are mandatory, optional, or hidden, tailoring the purchasing process to meet organizational needs or specific situations.

This functionality allows organizations to customize their procurement processes based on factors such as the nature of the purchase, supplier relationships, or internal policies. Different document types can represent various procurement scenarios such as stock items, consignment, or contract-based purchases. By adjusting the field selection through document types, an organization can streamline the requisition process, ensuring that users only interact with relevant fields, which can help minimize errors and enhance efficiency.

Other potential controls, such as plant, material group, or purchasing organization, might influence certain aspects of the purchasing process but do not directly dictate the field selection in the same way that the document type does. These elements pertain more to categorization, reporting, or validation within the broader procurement workflow rather than controlling the specific details of the data entry fields within the requisition.
