Apps cannot use External Content Types defined in the Business Data Connectivity Shared Service Application metadata catalog

Question

My issue is getting Unauthoraized exception while accessing external data in workflow 2013 context throw REST call (HttpSend).

I read several posts suggests to create BDC model inside App package, but it doesn't solve the problem. I created propriate model and achived possibility to view external data via web interface. (External list was created manually). But still Unauthoraized exception is there:

"Apps cannot use External Content Types defined in the Business Data Connectivity Shared Service Application metadata catalog. Apps should package any External Content Type definitions in a BDC model file which is packaged and deployed as part of the SharePoint App"

Appreciate any suggests.

Answer 1

After weeks of labour this issue decided to import external data direct to SharePoint internal lists using MS SQL SSIS adapters.
