I've inherited an old .NET application that uses the ACCPAC.COMAPI to create orders in ACCPAC.
Since the client has upgraded to Sage 300 2018, the application is returning a 'Error HRESULT E_FAIL has been returned from a call to a COM component' error. The application is able to create the header record, but during the detail creation it returns that error, specifically when it tries to set_value for the ITEM.
Any advice or suggestions on why this is happening?
Thanks
