Filter out individual field inside a tuple based on other field inside a tuple

I'm on MDM 7.1 SP07. I'm using MDM WD Component framework item details screen to build the screens needed for the client.

My MDM repository structure is something is as follows:

where "Company Code Data" is a tuple. Under "Company Code Data" tuple, I have 'Company Code' and 'Payment Method' as fields inside a tuple.

Now, my requirement is as follows:

Please note that the I have dragged and dropped the Company code tuple onto SAP MDM WD Item details screen.

If we try to add/change any row inside a tuple, say if user enters company code as '1020' inside the tuple for 1st row. Now, when he tries to select 'Payment Method' field he should be filtered such a way he gets only '1020' company code related payment method values for that 1st row.

Similarly for 2nd row, if user enters '2050' as company code value, all the payment terms values should be filtered only for company code '2050'....and so on...

Please share your thoughts/code pieces/configurations needed to achieve this requirement.

Please let me know if you have any questions.

Best Regards,

Santosh
