What are the different types of object repositories in QTP?

There are two types of object repositories

1. Per-action object repository (default)
2. Shared Object repository

We can set the default object repository mode, by selecting Test > Settings > Resources tab > choose Object repository types as “Shared” > click on Set as default button > Click apply and click ok.

Note: You can change the object repository type for the test only if the test does not include any steps or any objects and the test does not call any external actions.
