Save button is disabled on UI for Custom object - MDG 8

Hi,

I have created Single-Object processing UI for custom object by copying application configuration

USMD_GEN_OVP_TEMPLATE of the component FPM_OVP_COMPONENT.

Configuration ID for both UI and Communicator is same. After launch of UI, Change request Section with tabs General, Notes, Attachments and buttons Save, Submit, Refresh and Check appear on the UI.

All buttons are enabled only Save button is disabled.

Please guide me if there is any configuration missing or I need to write the code to enable the Save button.

Thanks,

Fattesingh Gaikwad
