How to fetch the calculation card association details TRU for a specific assignment

Summary:

I am currently working on fetching the TRU for Tax withholding calculation card.

The calculation card has association and association details. It uses US taxation component.

2 US taxation components (component sequence 1 , 2) are created one for each TRU, and specific assignments are added to each US taxation components .

I understand the PAY_DIR_REP_CARDS_F table stores the association details.

Can you please help on fetching the TRU for an association for a specific assignment number.
