How can we know AR Balance in actual sales based on customer invoices on Customer Credit Analysis window?

When a new difference item is created in Mixed Payment, 
it can be considered as a new sales transaction 
and hence hitting AR balance and Sales value in Customer Credit Analysis screen.

Because mixed payment contains below,
(1)AR Balance in actual sales based on customer invoices
(2)Amount generated by adjusting the difference.

As (1),(2) are all contained in AR Balance and Total Sales on
Customer Credit Analysis window of IFS.
So how can we know (1) on Customer Credit Analysis window?
