Read Component controller from another component

Hi,

I have a requirement where I need to populate certain Date fields for Items.

For this purpose, I need to read the component controller of one of the components that is being used as a Usage in the current component (BT120H_CPL).

My Idea is to -

1. Get the component usage BTComp1Item (Component: BT160I_CPL)

2. Read the Component controller of BT160I_CPL

3. Get the usage BTDates

I am stuck at the 2nd step .

Can anyone please help?

Any helpful answers will be rewarded .

Thanks!
