------------------------------------
Summary: Different price Order vs. Invoice due rounding
Key: OFBIZ-6436
URL:
https://issues.apache.org/jira/browse/OFBIZ-6436 Project: OFBiz
Issue Type: Improvement
Affects Versions: Trunk, Release Branch 14.12, Release Branch 13.07
Reporter: Ingo Wolfmayr
When creating an order with the following data, invoice and order calculates different prices due to different rounding strategies:
Example:
Net price: 8,70
Price Rule: 2 %
Calc price: 8,526
Order quantity: 2
Rounding order: 2 dec
Rounding invoice: 2 dec
Both: ROUND_HALF_UP
Calculation for order price:
8,526 * 2 = 17,052 --> Rouning = 17,05 (rounding takes place after multipying with the order quantity )
Calculation for invoice price:
8,53 * 2 = 17,06 (rounding takes place before multipying with the order quantity)
Rounding takes place on different places and leads to (from my understanding) misscalculation.
I create a patch that applies rounding on PriceCalculation level. Therefore:
1) get singe unit price and do all calculations on it (Price rules ...)
2) before forwarding the price, apply rounding (ORDER SETTINGS) on single unit price
As the invoice calculation uses the unit price (if invoice is associate with order) from ORDER_ITEM it will calculate with the already rounded value.
Result: Order Price = Invoice Price
I would appreciate any thought on it.
