How to Create a Purchase Requisition in SAP ME51N

Start from the SAP Easy Access menu

Open the SAP Easy Access main screen. The left panel displays the SAP menu with expandable folders such as Office, Cross-Application Components, Logistics, Accounting, Human Resources, Student Lifecycle Management, Information Systems, Tools, and WebClient UI Framework. No action is required yet — this is simply your starting point.

Expand the Logistics menu

Expand the Logistics folder in the SAP menu. This reveals subfolders including Materials Management, Sales and Distribution, Logistics Execution, Production, Plant Maintenance, and more.

Navigate to the purchase requisition creation transaction

Within Logistics, expand Materials Management, then Purchasing, then Purchase Requisition. Select ME51N – Create to start the purchase requisition creation process. The status bar at the bottom confirms with the message "Start of application: Create Purchase Requisition."

Open the Create Purchase Requisition screen

Double-click ME51N – Create. The Create Purchase Requisition screen opens, containing:

• A Document Overview panel that you can toggle on or off
• A header note section for entering general notes
• Tabs for Texts and Source Determination
• Item detail fields: Material, Short Text, Quantity, Unit, Delivery Date, Material Group, Plant, Storage Location, and more
• A toolbar with options such as Hold, Personal Setting, Save As Template, Load from Template, and Default Values

Enter a header note (optional)

If needed, enter a header note in the text box under the Texts tab. For example, you can type "This is a test purchase requisition" as the header note. You can use the line editor, SAP script editor, or continuous text data as required.

Enter the material number

Click into the Material field in the item entry grid and enter the material number, for example T-BW02-01. The header note you entered earlier remains filled in at the top.

Enter quantity, plant, and storage location

Continue filling in the remaining key fields:

• Quantity — for example, 10
• Plant — for example, 1000
• Stor. Loc. (Storage Location) — for example, braw

Press Enter to validate your entries. SAP will attempt to populate additional fields automatically.

Resolve a document type error, if it appears

If you see the error message "Document type NB not allowed with doc. category B (Please check input)" at the bottom of the screen, it means the selected document type (NB) is not valid for purchase requisitions. Click the dropdown next to the document type field at the top of the screen and select the correct type, such as zpr - Purch.requis..

Review your entries for spelling mistakes, especially in fields like Short Text or Storage Location, and correct them as needed.

Complete the remaining item details

Make sure all required fields are filled in:

• Short Text — for example, Hollow shaft
• Unit — for example, PC
• Delivery Date — for example, 08.01.2016
• Material Group — for example, 001
• Plant — for example, Hamburg
• Storage Location — for example, Raw Mat- V
• PGr — for example, 001

The lower "Item" details section automatically populates with the material and short text you entered.

Save the purchase requisition

Click the Save icon (diskette) in the toolbar to save your purchase requisition. Wait for the confirmation message indicating that the purchase requisition has been created.

Record the purchase requisition number

After saving, SAP displays a confirmation window with the newly created purchase requisition number, for example "Purchase requisition number 0020012210 created" (Message no. 06402). Record this number for your records or for further processing.

Verify the purchase requisition in ME53N

Navigate to transaction ME53N to display purchase requisitions. On the Display Purchase Req. screen, enter the purchase requisition number you recorded (for example, 0020012210). In the Document Overview panel on the left, find and select this number; the main panel updates to show the details of the selected requisition.

Review the purchase requisition details

Confirm that all entered details match your original entry:

• Header Note: e.g., "This is a Test Purchase Requisition"
• Material: T-BW02-01
• Short Text: Hollow shaft
• Quantity: 10
• Unit: PC
• Delivery Date: 08.01.2016
• Material Group: 001 (Metal processing)
• Plant: Hamburg
• Storage Location: Raw Mat- V
• PGr: 001

Check additional item data

Review the lower section tabs for further confirmation:

• Material Data confirms the material and short text.
• Quantities/Dates shows the quantity, delivery date, request date, and release date.
• Valuation displays the valuation price and total value — for example, Valuation Price 521,26 EUR and Total Value 5.212,60 EUR.

Ensure all values match what you expect.
