Reuse Data model - Activation error

Hi Experts,

     Activating a custom data model - Reuse mode, throws up a error stating " Table /1MD/MD______04A (Error adjusting the database)"

So i Followed by adjusting the database using (tcode se11), adjust and activated the database. This throws up warning that index id 01 could not be created in the database. although index exists for the table. The index shows up as activated but a warning 'Doesnt not exist in the database.'

An image of the data model entities attached. All

I searched in SDN community but couldnt get any answer or clue as to why data model is throwing up error while activation. Any clue will be helpful . Thanks in advance.

Regards
