To allow a specific user to delete a purchase requisition, you need to grant that user the appropriate permissions.
Here are the steps you can follow:
Go to the "Users" page in Dynamics 365.
Select the user you want to grant permission to.
Click on the "Permissions" tab.
Scroll down to the "Purchase Requisition" section and check the "Delete Purchase Requisition" permission.
Save your changes.
After these steps, the user should be able to delete purchase requisitions.
