Workaround (if update isn’t possible immediately):
This is a known issue in Dynamics GP 18.3.1245 when emailing SOP documents with multiple attachments — only the main document (e.g., Invoice PDF) is sent, while additional attachments are ignored, even if selected.
Solution:
Install the latest GP hotfix or year-end update (ideally GP October 2021 Patch or later, which includes a fix for this attachment issue). This update resolves the problem with missing attachments in SOP emails.
