Our application consultant came to me wanting to update custom fields which had been added to the InventSerial table.
He could pull the data down to Excel, but couldn’t push it back up to AX.
The first step (with thanks to http://dynamicsuser.net/forums/p/57272/307667.aspx#307667) was to add parm methods to the AxBC table class.
Yet that didn’t solve it, so I researched further and found that InventSerial table is part of the InventASNService.
Then I added an inbound port using that service’s operations (click screenshot) and activated the port.
Then I published data from excel to ax.
