Navigate to an Open Service by clicking the Maintenance dropdown (1) and selecting Services (2) from the menu or clicking Services (3) in the sidebar:
Click the Open Service from the table that you want to create the purchase order off of:
In this example we have one Repairer, ‘Example Repairer’ nominated as the Repairer (1):
In the Parts table we have two service parts added, one with no Supplier (1) and the other with the Supplier set as ‘Example Supplier’ (2):
Under the record header (at the top of the page), click the More Information link (1) and click the ‘+’ sign next to Purchase Order # (2):
Once the Loading page has cleared, you will now see two linked Purchase Orders. If you click on P-96 (1) in the example it will take you to the purchase order:
You can see that P-96 has been created with the Supplier as ‘Example Repairer’ (1) and the Items include the Part with the empty supplier (2):
If you go back to the Service and click on P-97, you will be taken to that Purchase Order and see that it has been created with the Supplier as ‘Example Supplier’ (1) and the Items include the Part with the matching Supplier (2):
