Issues in loading Cube and related Dimensions data from API

Hi there,

I am trying to build a custom API connector for Cubes and Dimensions data.

· What I would like to achieve is User can select one or multiple cubes.

· User can select any of the dimension tables as well directly.

· Once user click on load it should load all selected dimension tables and dimension tables related to the selected cubes

· If multiple cubes has same dimension tables then it should load those tables only ones.

I have attached a screenshot of what I have achieved so far. But Issues is that If user selects same table multiple time then those dimension tables are getting loaded multiple time.

Can anyone please guide me how to fix this or achieve in better way.

Regards,

Urmi
