Within SAP R/3 and ECC, the values on purchase order (PO) header status tab are not stored in table‐fields on the database, but are instead determined dynamically, which makes it difficult to develop custom purchasing reports that match the PO header information. The function module (FM) replicates the logic used within the PO program to ensure consistent matching of transactional information. Utilizing the asset can greatly shorten the development time for custom purchasing reports. The fields that are calculated bythis asset, include: PO delivered quantity, quantity Still‐to‐be‐delivered, and the quantity invoiced.
