Update a query based view Access 2013 Web App (1 Viewer)

I have just begun playing with Web Apps.

All is well with one issue bugging me to no end

I have a view (Based on a query involving two tables) that will not permit updates

All looks good, but my Edit option is grayed out.

Documentation is horrible. Can anyone suggest where I might begin to resolve this?

"Documentation is horrible.." thanks for the confirmation.
Will take a stab on this based on watching a couple of demos.
The recordset (so I am told) is limited so it doesn't swamp the network.
Kind of like running a Top 50 Query. That would seem concerning to me regarding updates.
My suggestion is to make sure the query only returns a single unique record for both tables. Then, use an update SQL statement rather than a recordset object.

Please be sure to let us know what you find. Your discovery would be valuable in the absence of real documentation.
