SAP Fiori Updatable App from gateway service

Hi,

1. I have created updatable project from Tcode SEGW in SAP.

2. Implemented the service UPDATE_ENTITY.

3. Activated the service to be consumed any where.

4. Using local sapwebide, created SAP Fiori Master Detail application.

But unable to trigger an update from App. Please help.

Thanks,

Suraj Pabbathi
