I’m trying to get case data from **ABC-Unit-Work1-Collection** (it’s a different application ) class, to **ABC-Unit-Work2-Collection** (different application concreate class inheritance “ABC-Unit”) class, how to get those case details through RD ?

Note: we don’t have a common class inheritance in these two classes

@AdarshaGouda you can fetch other class data which is in another application through api integration, you can’t use RD. Is it for security purpose both the class are in different application?

Thanks for your reply @Anoop Krishna,  
I have created one more class like **ABC-Unit-Work1-Collection-Work2** and mapped _Data table_ of **ABC-Unit-Work2-Collection** into the new class, so that i can create a RD to get all case details from required class. I got the solution for above query without API
