I am working on PowerApps with Flow connection to Business Central (on cloud). However, the API for the table that I want to use is not provided by Flow (I need to use PurchaseOrder, Flow only provides purchaseInvoices). I did some research and found out that I need create a custom connector which is a bit tricky for me. Is there any other ways to enable me to use that table? Or if not, can somebody please show me the easiest way to build the custom connector?
