Cannot find the object "tblFin" because it does not exist

Hi,

 

I am writing very basic query.

 

The same query is executing properly in new database.

 

use Finance

alter table tblFin

Add ComPurpose Varchar(100);

 

Error:

 

Cannot find the object "tblFin" because it does not exist or you do not have permissions.

 

Note: If i manually try to create column by right clicking on Table and then from design option Add column, Column gets added properly.
