Dear D365 Business Central Community, 

Many of our customers would like to have the Copy Document action available on their Sales and Purchase Advance Letters so that they can copy the details from the previously created documents and don't have to manually re-enter the same information every month.

In this case, the only document type available to choose from on the request page of the action would be Sales or Purchase Advance Letter, the Recalculate Lines toggle button wouldn't be available because there are no lines yet created on the advance letters, and the original status of the document would always change to New.
