Customizing report question

[Rich Bloch]

Hello all,

I'd like to customize the Account Summary report to make it report sales
based on a cash-basis instead of accrual.

To do this, I'd like to subtract Accounts Receivable from current Sales,
such that the Account Summary Report would report Sales as:

Income::Sales = (Income::Sales - Assets::Accounts Receivable)

How might I do this?

I see the iterative logic for each account in the account-summary.scm file,
but I don't know how to identify which account is Assets::Accounts
Receivable and which is Income::Sales.

Please advise.

thanks,

rich
