AR question: How to change default flexfield segment values at receipt distribution level

Hi there,

I might not know too much about AR and from what I understand, a misc receipt gets account distribution information from receivable activity and/or distribution transaction code. It also gets 'counter' account information from payment method. Let say we have following setup in activities and payment methods:

Receivable Activities: 123-2012-61000001-0000-0000-000000, which could be changed at receipt distribution.

Payment Method: 123-2012-10120010-0000-0000-000000

Question 1) We would like to enter a different balance segment 321 (we don’t allow inter-company posting) .  Do we have to setup all the balance segment values in Receivable Activities and Payment Methods as pairs?
