Hello,
I have downloaded the SDK for Sage50 to import an invoice into the ERP. While I am able to find the function to code a batch invoice, I am unable to find a way to create an invoice that's linked to a PO through SDK. In the ERP, the PO invoicing is done via the "Update Ledgers" function, but how do I replicate the same in SDK. For context, the PO and Delivery note are created in ERP, all I want to do is create an invoice in an external system against the Delivery note and then send it to the ERP, such that the PO is automatically updated to reflect the posting.
