Hello Ezra,
Regarding adding cross-referenced item numbers on Purchase Orders: At this time I was unable to add the cross-referenced item number to a purchase order, but we have a feature request documented for the ability to add additional fields to reports. I will update Development letting them know you are looking for this field on this report so they are aware of this request.
Here are the steps for modifying a report if you wanted to make any changes to an existing report:
1. In the search type Report Layout Selection and scroll down until you see Report ID 1322 or you can also search for purchase.
2. The default report that prints when you are printing PO's is the report with the description name 'US Purchase Order - Default Email Body', click on this report so it's highlighted.
3. Go to ACTIONS and select New.
4. For Report ID choose 1322
5. Check "Insert Word Layout".
6. You should now have a copy of the 1322 report ID with the description of Copy of Built-in Layout in your Customer Reports Layout list.
7. You can then export the layout, make changes and then import the layout.
8. To designate which format you want to use when printing Purchase Orders you can go to Report Selections Purchase and select Order...you can then click on the Email Body Layout Description and that will bring you to a list of reports which will include the Copy of Built-in Layout.
Regarding multiple warehouse locations: This functionality is currently in development. If you go to the following site: https://roadmap.dynamics.com/ and choose Edition as Business you can then click In Development and you will see Multiple Locations listed here as something that is in development.

Jennifer Reinhardt
