Everyone knows you can export grid data to Excel. And most people know you can paste back into a grid for entry. Did you know you can copy a field in a grid or multiple fields in a grid to paste back into JDE? The two most common single-field copies I use are the purchase order number and account number. For example, drilling into a journal entry from Batch Review to do some research, I see this. I can click on the account number field and hit Ctrl+C:

Then I can go to One View GL Detail (P09219) or Trial Balance Ledger Comparison (P09210A) and paste with Ctrl+V in the account:

In that same journal entry, there was a purchase order number, too - 00000698. Clicking on that field, I can copy that via Ctrl+C and paste it into the receipt inquiry (P43214), PO inquiry (P4310), etc.

I can even highlight/copy MANY rows like this:

Then paste into the same screen or anywhere I'd like - maybe even an email:
