Cash Discount clearing AP transactions

Hi All,

I'm testing how cash discount clearing account works in AP module.

When I create an AP invoice with "Net procedure" I get the following journal

Supplier                      CR                    110

TAX                         DR               10

Expense                    DR          90

Cash Disc Clearing      DR      10

When receiving the payment

Supplier                      DR                    110

TAX                              CR                              1

Bank                              CR                              99

Cash Disc Clearing      CR                               10

Problem is now my cash discount clearing account is zero and I cannot see the discount in the books? So what's the purpose of using this account?
