Account Determination Error - Discounts - ERS

Dear All,

When I am releasing my Billing Document, I am getting the "Account Determination Error".

My Requirement: Sales Discounts should not post to ERS Account Key.

Price - PR00 - 10000 ERL GL Account (10000)

Discount - K004 - 10%

900

Base Price 9, 100 INR

In the Accounting ENtry - it has to show only Customer Account 9100 Dr to Sales Revenue A/c 9100.

I don't want to show Sales Discount 900 Rs.

For this in pricing procedure configuration - i have removed ERS Act key (for not posting), becoz of this - I am getting the Account Determination Error.

Any Idea on How to Configure the above scenario?
