Most requisitions that include only material master items do not require Duke approvals; therefore, SAP quickly creates and sends purchase orders from these requisitions. Users will often not have the opportunity to change these requisitions. The instructions below demonstrate changes for a non-material master item, but they would be the same if you need to change a requisition for a material master item.

Once the requisition is fully approved, SAP will automatically change the Purchasing Group. Once that update occurs, users will no longer be able to make any changes to the requisition. This includes adding attachments.

Enter the transition action name, **ME52N,** in the **Command Field** or find the transaction in the **SAP Users Menu** in the **Purchasing** folder. Select the **Green Check** or **Enter** on the keyboard to launch the transaction.

On the **Change Purchase Requisition** screen, the most recent requisition displays. Select the **Other Purchase Requisition** icon.

In the pop-up that displays, enter the **Purchase Requisition** number of interest and select **Other Document.**

Select the next available line in **Item Details** and enter the new information into the requisition. Please note: you can also modify the existing line if, for example, you need to change the quantity or unit of measure.

If you are adding a line, continue completing the requisition as outlined in the [Create a Purchase Requisition for Items Not in the Material Master.](https://scribehow.com/shared/Create_a_Purchase_Requisition_for_Items_Not_in_the_Material_Master__ME51N__nJRBc_TSSheedoV8T6GuhA) If you are changing an existing line, you can also make changes to information found on the tabs.

Once you've entered all data and attached supporting documentation, select **Save** to create the requisition and launch the necessary approvals defined by your business unit and Duke's standard operating procedure.

Notice that the purchase requisition number displays with a confirmation of the change.

Select the **Approval Details** tab to see the workflow approval. Notice that the first workflow is **Canceled**. SAP created a new workflow that will include your changes. Approvers will need to approve the requisition again, even if it was approved before you made the change. Please note: You may need to use the right scroll bar on the **Approval Details** tab to view the current workflow.
