This should be implemented as a standard feature. Many Business Central users frequently question why they cannot use the international RF reference number format. Creditors commonly issue invoices with RF reference numbers, but these cannot be used directly in Business Central. As a workaround, users must manually remove the first four characters to extract a usable reference number.Given that the RF reference number has been an ISO standard since 2008, the lack of support for it in Business Central is a notable gap.
Additional details: Potential root cause identified I've been investigating this issue and found a specific cause for the margin behaviour in the Editor.The .inlineFrame class on one of the container elements uses display: flex. This prevents CSS margin collapsing from working in Design mode.When I removed display: flex from .inlineFrame, margins started collapsing again in the Editor — matching what you see in Preview/Test and in email clients like Outlook and Gmail. Steps to reproduce:Add two stacked sections or text blocks with top/bottom margins in the Email Editor.In Design mode, notice the extra spacing between them (margins are not collapsing).Inspect the container and find the .inlineFrame class with display: flex.Remove display: flex from that class.Margins now collapse correctly in the Editor, matching Preview/Test output.This suggests the issue is not just a visual limitation of the editor — it may be a specific CSS property that can be adjusted without affecting drag-and-drop functionality.
