Matthias Mekschrat h_DA WS 2011Logistical applications and optimizationsSlide 8 Functionality of purchase and supply processes, Part 1 Integration of purchase processes into the supply chain results in lower costs by reducing stocks and delivery time Problems and potentials Delivery „just in time“ is one major demand for an optimal supply chain. This is only possible with the integration of purchase processes into the total supply chain process in order to provide appropriate informations

17. Matthias Mekschrat h_DA WS 2011Logistical applications and optimizationsSlide 17 Purchase execution processes Generated automatically by the MRP Internal planned purchase according to disposition needs Purchase requirements Material, due date and quantities are known Supplier is still not named at this phase Quantities are calculated according to the given demand and the lot sizes in the master data Lot sizes can be customized by giving a fixed size or by calculating a dynamic lot according to defined rules Purchase requirements are transfered to purchase orders by decision of the purchase department

18. Matthias Mekschrat h_DA WS 2011Logistical applications and optimizationsSlide 18 Purchase execution processes Potential suppliers are requested to place an offer for a certain potential purchase order Bidding Material, due date and quantities are known (usually equal to the purchase requirement) Potential supplier offer a certain price and certain conditions An offer usually has a period af validity If an offer is accepted by the customer, the supplier is bound to that offer Purchase requirements and offerd conditions are jointly transfered to purchase orders

19. Matthias Mekschrat h_DA WS 2011Logistical applications and optimizationsSlide 19 Purchase execution processes Generated in the purchasing department by transferring the purchase requirement Purchase orders Material, due date and quantities are clear according to the purchase requirement The actual supplier has to be named according to the best offer or other restrictions ( Availability, „A-Supplier“ or contingents) Material availability at favoured suppliers might lead to splitted purchase orders Supplier‘s lot sizes or delivery schedules might lead to a change in the purchase order Purchase orders are transfered to the choosen supplier by different ways of communication

20. Matthias Mekschrat h_DA WS 2011Logistical applications and optimizationsSlide 20 Purchase execution processes The ordered material is physically delivered to the requested point of receipt Delivery The received amount - if still subject to an incoming goods inspection - is booked into a special check inventory The received amount - if accepted - is booked into the customers inventory The material will become customers property with the booking into the inventory The purchase order will be closed or partly closed depending on the received amount an the rules to accept variations

21. Matthias Mekschrat h_DA WS 2011Logistical applications and optimizationsSlide 21 Purchase execution processes This step is only needed, if no agreements are made with the supplier that quality checks are done at the suppliers plant Quality checks on delivered material Normally the customer only receives a certificate together with the delivered material Quality ckecks can be done permantly for each delivery, at random according to a check plan in the master data or only in certain cases (e.g. damaged package) If a quality check is required, the delivered material will only be taken into the customers stock and property, if all requirements are fullfilled according to the customized check plan

22. Matthias Mekschrat h_DA WS 2011Logistical applications and optimizationsSlide 22 Purchase execution processes After the material was accepted by the customer, the supllier gets a material receipt Payment The supplier than sends his invoice to the customer The invoice is compared with the purchase order data and the results of the quality checks If the invoice is accepted, payment will be activated Material receipts and invoices are transfered to the choosen supplier and to the customer by different ways of communication The purchase process than is completed
