Hey Guys, how can I show the email history in the Communication tab (Invoice) of the Custom button "Email"?

somehow, might require you to either load message records linked to the transaction that you are currently working with or might as well do a search for the linked transaction and use the search results. but either ways, you still have to work on the HTML component since it would most likely by text values returned

might want to better explain what you mean. dont know what you mean by show email history when its already show in the communication subtab

@battk I created a custom button that sends an email to the customer. But the history, which shows in communication, only for standard email button, not for a custom button.

set the RelatedRecords of email.send(options)

Thanks @battk for your help. Now I am able to show the history in Communication tab. Thanks Again.
