Duplicate attachment to another record

[abidoss]

How can I copy (duplicate) an attachment via a flowchart or workflow, without keeping the same ID when copying it to another record?

You need to create a new Attachment record with 'sourceId' set to the sourceId of the Attachment record you copy or the id of the sourceId is empty.

$sourceId = $attachmentAttributes['sourceId'] ?? $attachmentAttributes['id'];

I didn’t quite understand how this works — is it possible through a formula or a script before launching the BPM?

In Workflows, when using UI for copying field, copying File and Image field was not implemented (it was only for Attachment-Multiple). I'll add it the next hotfix version.

It's also possible to use formula to copy attachment – in Create/Update record actions.
