RE: Email Body for a custom report in Business Central
To my knowledge only WORD layouts can be used in the email body, RDLC layouts are not supported. (Why I have no idea...)
Set up email in Business Central (contains video) - Business Central | Microsoft Docs
Technically there are several ways to 'change' behavior and customize what needs to happen:
ALAppExtensions/Modules/System/Email at main · microsoft/ALAppExtensions · GitHub
ALAppExtensions/Modules/System/Word Templates at main · microsoft/ALAppExtensions · GitHub
ALAppExtensions/Other/EmailAddressLookupDemo at main · microsoft/ALAppExtensions · GitHub
Issues · microsoft/ALAppExtensions · GitHub
