Hi All, I'm facing an issue where sales invoices created via a restlet by a multi-threaded integration get stamped with the same document number (tranid), because of being created in the same split-second. Has anyone experienced anything similar? Thanks!

No but regardless you should report that - it should not be possible I would say, so maybe a bug?

Auto-Generated Document Numbers tells the configuration required for allowing duplicated document numbers and a suggested field to use to prevent it

Yes, I have seen that.

@battk - I found it - it's a "field" on the form, which instructs the system to generate the document number on save, rather than on load. There is also an official article about this: https://suiteanswers.custhelp.com/app/answers/detail/a_id/94171/loc/en_us
