Update target button is disabled after schema comparison

Question

I have created database project using VS 2012. Once the schema comparison is done, the update target button should be enabled to sync with target.

But it\'s not get

Answer 1

Typically the update button is grayed out when the database objects are available in the separate sql files physically inside the database project but are not included in the database project itself. I simply added those sql scripts into the project and the update button got enabled after comparing the schema.
