Hi Scholars,

When I'm trying to create a database diagram for my tables., First it prompts me saying that - "This database does not have one or more of the supported objects... Do you wish to create them? I know this is normal when you don't have any diagrams. But after clicking "Yes", I get the following error which is attached.

I tried changing the database Owner to "sa". But, still the same error. Interestingly, other databases that are already having the database diagrams (created by others), are allowing me to create new diagrams in those databases. 

The only difference is, I created this database where I'm trying to create diagrams on. 

Please suggest me how do I get this working.

Thanks in advance
