Hello, is it possible to get a calculated field to show the quantity remaining vendor bill created from a po? our users would like to see for each line whats is the quantity that can be billed. thank you.

like quantity - quantity billed = remaining to be billed?

can you display that value on the bill itself?

In a custom field it's likely yes. But why not look at the purchase order?

our a/p team sometimes copies a bill and would like to see the amount remaining
