Having said all that, there is a way to issue the corrective invoice via Vince using a couple of workflows:

1. Export or populate the invoice lines with errors into excel worksheet, from an invoice # in OSBSTD or ODLINE
2. Create a CO credit order type that matches the lines you want to correct
3. Manually correct credit prices & discount in Excel
4. Push back a new CO type credit but to rebill with new prices

It's a couple of workflows and  Read more...clicks but still probably quicker than doing it manually, particularly if you have a lot of them! Show less...

To my recollection there isn't a way to do this via the existing APIs, though there is an enhancement request to enable this feature (please vote!) - https://mingle-portal.us2.prd3.inforcloudsuite.com/v2/CONCIERGE_PRD/?LogicalId=lid://infor.cxp.1&Tab=ERS&ERId=119987

Do you know what APIs would be required to do so? If not, I would also post this in the general MUGA forum.
