How to Cancel a PO in SAP

If you need to cancel a PO in SAP, you cannot delete the purchase order record itself — instead, you cancel it by deleting its line items and any associated service entries. This guide walks you through how to cancel a PO in SAP using transaction ME22N, including removing service line items and flagging the PO line item for deletion.

Prerequisites

• You must have the necessary authorization in SAP to delete purchase orders and line items.
• Deletions are typically irreversible and may impact downstream processes, so proceed carefully.
• If the PO is in an approved state, you will need to cancel its release before making changes.

Understanding SAP deletion logic

Before you begin, it helps to understand how SAP handles PO cancellations. Purchase orders are not physically deleted from the system. Only the line items within a PO can be deleted, by setting a deletion flag.

If services are maintained against a PO line item, you must delete those services first before you can delete the PO line item itself. After deletion, the PO remains in the system for audit and traceability purposes, but the flagged items are excluded from further processing.

1

Open the SAP Easy Access screen

Launch SAP and make sure you are on the SAP Easy Access main menu. Confirm that you see the navigation tree (Favorites, SAP Menu) along with your organization's welcome screen.

4

Switch to change mode

If the PO opens in display mode, click the Display/Change button (or press F7) to enable editing. Confirm that the button is highlighted and that the editable fields are now active.

5

Cancel the release if the PO is approved

If your PO is in an approved state, use transaction code GenVMP_INI_AMNT to cancel the release. This step is necessary before you can make changes or delete PO line items. Make sure the release is fully cancelled before you proceed.

6

Select the service line items to delete

Click the Services tab under the Item section. Review the list of service line items — for example, Service No. 71000182, Short Text SIM CHARGES, Quantity 1, Gross Price 10.00 INR. Select the checkbox next to the service line(s) you want to delete.

7

Delete the selected service line items

With the relevant service line(s) selected, initiate the delete action, typically by clicking a Delete button or using the menu. The selected line(s) will be highlighted for deletion.

8

Confirm deletion of the service line items

A confirmation dialog appears, stating "Delete Lines – The selected items will be deleted." Click Yes to confirm and proceed with the deletion.

9

Verify that the service lines have been deleted

Click the Services tab under the Item section again. Confirm that all service lines previously associated with the PO line item are now removed — the list should be empty or show zero values for all fields. This confirms that the service lines have been deleted, which is required before you can delete the PO line item.

10

Delete the PO line item

If you need to delete the entire PO line item, select the line item in the header section (for example, Item 10). Mark the deletion flag, or use the delete function according to your organization's SAP configuration.

13

Verify the deletion status

Confirm that the PO line item shows a net price of 0.00 INR and is flagged as deleted. Make sure the Services tab is empty or that all values are zeroed out. The confirmation message "Need Based Order 4200927031 changed" should appear at the bottom of the screen.

Summary

By following these steps, you can cancel a PO in SAP by deleting its service line items and flagging the PO line item for deletion using transaction ME22N. Keep in mind that the purchase order itself remains in the system for audit and traceability, even after cancellation, and that these deletions are typically irreversible.
