SAP BPC 10.0 NW - Calculation of different account types

Dear Experts,

I got an issue, what I don't understand.

Scenario:

I plan to set up a little sales planning with a profit and loss planning on top of it.

Dimension: SalesAccount (Type = A)

I wrote a little script logic, which calculates the values for Total Sales Revenue, Total Sales Profit and Total Cost of Goods Sold. It looks as follows (extract):

*WHEN SalesAccount

*IS "SALESQUANTITY"

*REC(SALESACCOUNT = "TOTALSALESREVENUE", EXPRESSION = %VALUE%*[SalesAccount].[SALESUNITPRICE])

*REC(SALESACCOUNT = "TOTALCOGS", EXPRESSION = %VALUE%*[SalesAccount].[UNITCOST])

*REC(SALESACCOUNT = "TOTALSALESPROFIT", EXPRESSION = %VALUE%*[SalesAccount].[SALESUNITPRICE] - %VALUE%*[SalesAccount].[UNITCOST])

*ENDWHEN

*WHEN SalesAccount

*IS "SALESUNITPRICE"

*REC(SALESACCOUNT = "TOTALSALESREVENUE", EXPRESSION = %VALUE%*[SalesAccount].[SALESQUANTITY])

*REC(SALESACCOUNT = "TOTALSALESPROFIT", EXPRESSION = %VALUE%*[SalesAccount].[SALESQUANTITY] - [SalesAccount].[TOTALCOGS])

*ENDWHEN

*WHEN SalesAccount

*IS "UNITCOST"

*REC(SALESACCOUNT = "TOTALCOGS", EXPRESSION = %VALUE%*[SalesAccount].[SALESQUANTITY])

*REC(SALESACCOUNT = "TOTALSALESPROFIT", EXPRESSION = [SalesAccount].[TOTALSALESREVENUE] - %VALUE%*[SalesAccount].[SALESQUANTITY])

*ENDWHEN

After creating an input schedule and planning some values (Sales Quantity, Sales Unit Price and Unit Cost), I was pretty surprised about the result in the BW cube. Please see the calculated values below:

Could somebody please explain me, how Total Sales Revenue, Total Sales Profit and Total Cost of Goods Sold are calculated regarding the different account types mentioned before? I don' t understand that so far

Thank you in advance,

Karsten
