Set a value for a attribute in another component

Hi,

I have enhanced the BT115IT_SLSO/Items view and the BTADMINI context node. Iu2019m checking the product in the method GET_ORDERED_PROD.

Please, at this point how can I set a value to the PMNTTERMS attribute of the BTPRICINGSET context node of the BTPAYMENT/HeaderPayment view?

Thanks in Advance
