Total Sales = Sales Unit x Sales Price in same application

Question

Hi experts,
I have read and tried some of the script logic in the forum but I'm still not able to get the results I want.
I have a application with the following dimensions: account,category,time,entity,datasrc,bussegment,inputcurrency,scd,vcd.
The same price apply to all combination of scd and vcd, the units will vary depending on the scd and vcd combination.
For example, when records are posted, the records in DB as follows:
Salesprice:
Account | Category | Time | Entity | Datasrc | Inputcurrency | SCD | VCD |
sprice | budget |2006.jan | HK | input | usd | sdump | vdump | $10
Salesunits:
Account | Category | Time | Entity | Datasrc | Inputcurrency | SCD | VCD |
sunits | budget | 2006.jan | HK | input | usd | aax | aan | 50 |
sunits | budget | 2006.jan | HK | input | usd | coc | cex | 100 |
TotalSales should be:
Account | Category | Time | Entity | Datasrc | Inputcurrency | SCD | VCD |
tsales | budget | 2006.jan | HK | input | usd | aax | aan | $500 |
tsales | budget | 2006.jan | HK | input | usd | coc | cex | $1000 |
Have tried using script logic:
[#tsales]=sunits * [scd].[sdump],[vcd].[vdump],[account].[sprice]. For this syntax, total sales will only be updated when salesunits is updated. The total sales remain unchange when there's a change in price.
Please advice on how should the price be retrieved?

Assuming you're on BPC 5.1 for MS, I'd recommend using SQL syntax not MDX.
Also, I'd recommend using InputCurrency as the dimension name in your rate app, not your reporting app. That's not critical, though. What is a little strange is that you're doing this data manipulation in USD, not LC. That's up to you, though.
// we take entity, category, time, SCD and VCD from the user's data submission
// entity, category & time require no shift of data
// but since we want to re-calc all SCD and VCD when the price changes,
// we need to pick up ALL members of these two dims
*xdim_memberset SCD = <ALL>
*xdim_memberset VCD = <ALL>
// fix other dims; this is optional
*xdim_member datasrc = input
*xdim_member inputCurrency = USD
// this is optional, but may help performance - but ONLY IF this is the only logic in your commit block.
*xdim_member account = SalesUnits
*lookup
*dim MyPrice:Account="SalesPrice"
*dim scd="sdump"
*dim vcd="vdump"
*endlookup
*when *
*is *
*REC(factor=lookup(MyPrice),account="TotalSales")
*endwhen
an alternate way of handling the when/if, if you want to be really, really belt & suspenders about it:
*when VCD
*is not VDUMP
*when SCD
*is not SDUMP
*REC(factor=lookup(MyPrice),account="TotalSales")
*endwhen
*endwhen
