After copying an invoice - the system is clearing out the post date that was already keyed in or auto-filled. The other info keyed remains for the new invoice like invoice date, due date, and amount. Why it's clearing the post date? Leave it with the new info just like the other fields.
We use the copy feature mostly for the description (to stay consistent) and the distribution, but then have to go back and retype the post date every time. It's frustrating.
I find it unlikely that a business would want to copy the post date of an invoice so I'm confused at why that would be a "copied" field on a new invoice.
