Hello all, I just wanted to reach out again in case other folks also come across this thread. I am able to clarify that we can confirm that there is currently private functionality that was made available in February of this year that may help with the above use-case. However, at the moment it is only available to select ERP integration partners and we are unable to provide any further information about whether/when it will be released publicly at this time.
In the meantime, we’d recommend reaching out to your ERP providers directly for further information like @Daelan_Wood and @Graham78 mentioned above. Hope this helps.
