I just created a bunch of new invoices from Recurring Sales Invoice “templates”. Everything worked as expected. However, I notice that the resulting Invoice headers when viewed from the sales invoice screen or emailed, all have space taken up in the header for Sales Quote# and Purchase Order# of which there are neither.
When I create a manual invoice (not from a recurring template) these fields do not appear in the header so it seems to be inconsistent. Anyway they could not appear if (respectively) there was no PO# actually entered or were not created from a sales quote? I do not have sales orders or sales quotes even turned on.
