Perform the following:
To map a user to a CCG you must be logged in as the user you want to map.
1. Open the Code Control Groups window (Toad menu bar|Team Coding|Code Control Groups).
2. Select the appropriate CCG.
3. Click the Map Current User button on the toolbar.
4. If the CCG contains object masks for multiple schemas, follow the prompts to select the schema you want.
5. If required, perform an Import to update the objects in your schema.

OR check Toad's Help file.
You can associate a developer's schema to a particular Code Control Group (CCG). This means, if you are the developer, that when you open an object in your own schema, Toad searches for the object in the mapped CCG and locks it as if you had opened it from the original schema. When you check an object out, the archive for the original schema is checked out and the object is locked in both your schema and the original schema.
This can be useful in cases where you often work in your own schema, but on projects containing objects that actually exist in another schema. So when you map a user to a CCG, you basically create a new CCG identical to the first, but with all object masks referring to a particular user schema. The same VCS archive is shared between the user schema and the schema contained in the original CCG.
