Hi Arun,

You shouldn't have to start a Scope yourself, the framework will take care of that for you.

If you use the regular `Repository<Product>` interface instead of using the repository which gives you the `LockAwareAggregate`, you should be fine.

The `Aggregate<Product>` you'd pull from that has a `invoke(Function<T, R> invocation)` function with which you can call your `depreciateStock()`, which the framework will correctly wrap in a Scope.

Apart from that, I'd suggest to have your `@CommandHandler` annotated functions on the Aggregate directly instead of in a separate component, as the format you're using more so resembles Axon 1 than 2 or 3. Additionally, don't forget to use the `@AggregateRoot` (or `@Aggregate` if you're on Spring) annotation on your Aggregate class.

Hope this helps!

Cheers,

Steven
