MRP and Material Purchasing with SAP By now, you have successfully created a production schedule for your LX model Beach Cruisers. In this exercise you will see the effects of the MRP run from the previous exercises, and create a purchase order for some materials to be used in the Beach Cruiser production. Part 1: View Stock/Requirements List You have already seen that your LX Beach Cruisers have been scheduled for production. Now let’s take a look at what the MRP run did for the materials needed for the production of the Beach Cruisers. From the SAP Easy Access User Menu: Logistics Production MRP Evaluations Stock/Requirements List The materials used for Beach Cruiser production are either purchased from an external vendor, or produced by SOS. Let’s look at one of the externally purchased materials. Enter BP-01 (this is the steering controller for the Beach Cruisers) in the material box (your plant should already be entered for you), and click the enter button. Examine the displayed stock/requirements list. You will notice that for every scheduled date, 10 BP-01s are needed. If you think back to the BOM for your LX Beach Cruisers, you will remember that each Beach Cruiser requires 2 steering controllers. You will also recall that for every scheduled production day for your LX Beach Cruisers, 3 will be made. By using these two pieces of information during the MRP run, the system correctly (and automatically) determined that you need 6 steering controllers for each production day. It is important to note that you never had to complete a separate scheduling process for the steering controllers; the MRP function completed the task for you.

Part 2: Vendor Purchasing Information Records As mentioned in part 1, the material BP-01 (steering controllers) are purchased from an external vendor. In SAP, the information regarding individual part vendors are kept in purchasing information records. This record holds information regarding the time it takes a vendor to ship orders, the price a vendor charges, and minimum, maximum, and standard order quantities. In class, you will have calculated an economic order quantity for the steering controllers. Let’s enter that quantity in the purchasing information record for a vendor. From the SAP Easy Access User Menu: Logistics Materials Management Purchasing Master Data Info Record Change Click inside the Vendor box, and click the round gray selection button to the right of the box. Make sure you are on the Vendors (general) tab, and click the enter button to see all available vendors for SOS. When the vendor list displays, you will see that there are several different vendors available for controls. The SOS purchasing employees have contacted the different control vendors, and were able to make a deal with Cable Controls Inc based on the order quantity SOS has determined best fits there needs. The other vendors either could not ship the number of controllers SOS needed, or were too expensive. Double click on Cable Controls Inc to select the vendor. You should see the vendor number in the vendor box. Enter BP-01 in the Material box. The Purchasing org. and Plant boxes should already be filled in. Click the enter button to display the purchasing information record for Cable Controls Inc. Now click the Purch. Org. data 1 button at the top of the screen to see the data relevant to purchasing. Upon examination of the Purch. Organization Data 1 screen, you will learn some important information. It takes 1 day for Cable Controls Inc to deliver an order of steering controllers, as indicated in the Plnd dely time (planned delivery time) box. The Net price box shows the current price paid per steering controller ($20.00). You can also see that there is no minimum, or maximum order quantities set. Currently, the standard order quantity is set a 1 unit. Since SOS has determined that it would be beneficial to order several steering controllers at one time (primarily to save on delivery and receiving costs), enter your economic order quantity of 1033 in the standard qty and minimum qty boxes. By doing this, you are telling SAP to always order 1033 steering controllers instead of going through the added expense of ordering 1 at a time. We will leave the maximum qty box empty for now, just in case we need to order a larger amount due to an unexpected large order. Now click the save button to enter the change in the system. Return the SAP Easy Access User Menu using the green back button. Part 3: Convert Planned Order to Purchase Requisition You will recall from part 1, that the stock/requirements list for the BP-01 material shows several planned orders (PlOrd), one for each production day. Before creating a purchase order from Cable Controls Inc, we need to convert one of the planned orders in the stock/requirements list into a purchase requisition. This conversion is a safeguard placed in the system to allow for unexpected changes. If for some unexpected reason production will not be available on a previously scheduled day, the head scheduling employee will simply refrain from converting the planned order for the steering controllers on that date into a purchase requisition. This will prevent the system from automatically updating inventory which does not need to be ordered. Now let’s create a purchase requisition for some steering controllers. Using the same procedure as before, display the stock/requirements list for the BP-01 material. Locate the planned order (PlOrd) for the date of 12/15/2005. Click on the small magnifying glass located to the left of this row. A small window will appear giving you some information regarding the planned order. You will see that the order will actually be sent to Cable Controls Inc a few days before 12/15/2005. The difference in the dates is to ensure that the steering controllers will be available for production on the date you selected (12/15/2005). It would be somewhat foolish to schedule steering controllers into production on the day they arrive. What would happen if the delivery was late, or if some of the steering controllers were damaged during transport? The Beach Cruiser production for that day would be less that expected. To avoid this very expensive possibility, SOS scheduling has added a few days for delivery, inspection, and receipt of the steering controllers. This is one very important aspect of MRP. At the bottom of the small scheduling window, you will see a -> Pur.req. button. This button will take you to the planned order conversion screen. Click the -> Pur.req. button now. On the Convert planned order to pur. req. screen, click the Assign supply source button. Assigning the supply source (vendor) tells the system which vendor will be used for the order. This in turn allows the system to apply information from the proper purchasing information record. Enter 20 in the Storage location box so that the SOS receiving employees know where the steering controllers should be sent and click save. You will automatically be taken back to the stock/requirements list for the steering controllers. Click the refresh button at the top of the screen, and note that your planned order (PlOrd) has changed to a purchase requisition (PurRqs). Return the SAP Easy Access User Menu using the green back button. Part 4: Convert Purchase Requisition to Purchase Order You have now successfully created a purchase requisition for the steering controllers. This information will become available to the SOS purchasing staff. The purchasing staff will review the purchase requisition, and upon approval, will convert it into a formal purchase order to be sent to Cable Controls Inc. Using the same procedure as before, display the stock/requirements list for the BP-01 material. Locate your purchase requisition (PurRqs), and click the magnifying glass to the left of the row. A small window will appear with a -> Purchase order button at the bottom. Click on the ->Purchase order button to be taken to the create purchase order screen. On the left side of the screen, you will see a Document overview box, which lists your purchase requisition number under the heading “Open requisitions.” Click on the purchase requisition number once to highlight it. Now click the adopt button (looks like two small sheet of paper, and is located near the top of the Document overview box) to copy the requisition information to the purchase order. As the purchase requisition information is copied to the purchase order form, you should see a warning appear at the bottom of the screen. Click on the warning message to see what it says. The warning is reminding you that the purchase requisition was only for 10 steering controllers, but your agreement with Cable Controls Inc is now for the number of steering controllers you entered as the economic order quantity. Close the error message box, and look at the PO quantity (purchase order quantity) on the purchase order form. SAP has automatically adjusted the ordered amount to equal the economic order quantity. In this way, SAP continues to make sure that the information used is always accurate and up to date. Now click the save button. You will see a box asking you if you wish to save. This box is appearing because of the difference in the requisition and order number, and because the system does not have an order output device configured. In an actual business setting, an output device at the Cable Controls Inc office would be configured so that your purchase order would automatically be faxed or e-mailed to the vendor. Click save on the pop-up box. You should automatically be returned to the stock/requirements list for the steering controllers. Click the refresh button (Looks like two blue arrows in a circle near the top of the screen) and note that your purchase requisition (PurRqs) has now changed to the abbreviation for Purchase Order. Click the magnifying glass to the left of the purchase order row, and record the Purchasing doc. Number for next time. Return the SAP Easy Access User Menu using the green back button.
