Dear SAP Experts,
Some companies have not prepared the documentation for the user guide of SAP Purchase Order but this document should always be in your folder.
Every company has a different system with their custom developments but the below fields might be familiar.

For Account Assignment, if the item is purchased from domestic market (Standard PO), “Asset” field is set as “DUMMY” or any dummy code which is your company used. If this is an import subject, an asset number is obtained from Accounting Department and then this number is entered in “Asset” field.

1.2. Creating PO Via Requisition (PR) Assignment List
This way of creating PO is the mostly used one. It is the way to create PO with assigned PR documents. Many of the information comes from the assigned PR.
Following SAP Menu | Logistics -> Materials Management -> Purchasing -> Purchase Order -> Create -> Via Requisition Assignment List |
Transaction Code | ME58 |
By following the above path or directly typing the transaction code ME58 in transaction box, below screen will be opened:
In this screen, it is possible to filter assigned PRs with respect to different parameter. After filtering and executing this selection(s) with 
button , we will reach below screen view on which requested PRs are displayed.
By double clicking on the expression “W/o Outl. Agmt” below window is opened. Proper PO document type is choosen and purchasing group and purchasing organization fields are entered properly if not filled. Then, by clicking
button, our settings are brought into PO creation screen.
By picking the PR request on the left side and moving it into the basket, all information in the PR are brought into PO document:
WARNING: It is strictly recommended that after bringing PR into PO, currency, prices, payment terms, delivery terms and other data coming from vendor master data to be checked specifically for the new PO. This is because those information are master data but one can create a PO for the selected vendor with different terms and conditions.
If we want to change the delivery date, it is required to change the in the “Statistical Delivery Date” field under “Delivery Schedule” section. For import POs, this date represents the delivery date of the vendor with respect to delivery terms. For example, if this would be a FCA delivery, then, the date in “Statistical Delivery Date” represents the date that vendor will deliver the goods at the delivery point. However, date in the “Delivery Date” field represents the date that the item will be in your company’s stocks.
Generally, “Delivery Date” should not be changed. Instead, one can manage delivery date of the item to your company’s stocks by changing confirmations. Confirmations will be shown later.
After completing all necessary fields, PO is checked for any problem message by clicking
button . Then, PO is saved by clicking
button. A PO number is generated by system.
2. Changing PO
This transaction is used to make changes in a previously created PO.
Following SAP Menu | Logistics -> Materials Management -> Purchasing -> Purchase Order -> Change |
Transaction Code | ME22N |
By clicking the transaction on the list, below screen is opened:
Always, last created/saved PO will be brought in the screen. To display a different PO, by clicking
button, required PO number is written and
button is clicked.
After completing all changes, PO is checked for any problem message by clicking 
button . Then, PO is saved by clicking
button.
3. Confirmations
After forwarding PO document to the vendor, confirmation data received from the vendor is stored in the system. For this action, again, PO change transaction is used. Confirmations are seen by planning department via “Stock/Requirements List” screen (MD04) and production plans are made according to confirmed delivery date(s) and quantities.
Following SAP Menu | Logistics -> Materials Management -> Purchasing -> Purchase Order -> Change |
Transaction Code | ME22N |
Before saving the confirmation information, planning departments will see PO item stock availability date as 29.07.2015 (29.07.2015 + 0 days for material quality control (this data is defined in material master data)).
By default, Confirmation Control Key is selected; it is defined in vendor master data. To enter confirmation data, first, under “Confirmations” section, “AB-Order Acknowledgment” is chosen in CC (Confirmation Category) field. Then, delivery date confirmed by vendor is typed in “Delivery Date” field and quantity is entered in “Quantity” field. And, by pressing enter (skipping yellow warning messages), confirmation information are set.
After entering confirmation data, planning will see the PO item as below:
It turns out that item will be available for production on 10.08.2015 (01.11.2012 + 0 days for material checks). Since this will affect production plans, it is important to inform planning department about such change before or just after entering the confirmation data. For import PO, confirmation data which are stored in this way again represents the item’s delivery date to Evyap stocks. But, this time this date is an estimated date because it depends on freight period, custom clearance operations and in-land freight periods.
After all, if all confirmation data is set, then by clicking
button, changes are saved.
4. Displaying PO
This transaction is used to display a previously created PO.
Following SAP Menu | Logistics -> Materials Management -> Purchasing -> Purchase Order -> Display |

Always, last created/saved PO will be brought in the screen. To display a different PO, by clicking
