Approve/ Submit Button missing

Hi All,

I've enhanced the Data Model 'MM' and followed steps as given from Page 31 till 111 but I'm unable to see Tabs in create Request Pages, refer below -

The Data Model also is 'Inactive', please refer below -

Though Data Mapping says it's already completed -

I'm unable to see any Approve/Submit button as well -

I feel all these are linked together and buttons would reflect once UIBB is visible. Please help me where could I refer or rectify to get these correct.

Thanks a lot.

Regards,

Kumar Saurav.
