Scripting assistance creating a calculated dimension

[QFanatic]

hi everyone.

Please find attached.

I have to create a calculated Dimension in my model where I calculate 3 items: (this would be to display in a chart using Calculated Dimension)

1. Value of Debits (would be Sum(val) where Chan = '1SA'). This I would need to calculate for 3 periods - vMaxdate, v1MonthAgo and v2MonthsAgo.

2. Financial Volumes (would be Sum(vol) where Chan = '1SA' and Type = '1'), Also for same 3 periods.

3. Non Financial Volumes (would be Sum(vol) where Chan = '1SA' and Type = '2'), Also for same 3 periods.

if I dont go this route, I'd have to do the long way using Valuelist, and I'm a bit lazy...LOL.  I assume, adding these 3 dimensions, would multiply my data volume by 3 - correct?

Please tell me there is an easy way of doing it? All help appreciated.

Thanks.

not sure I clearly understand what you want to do, did you want to create 3 new fields based on the value of a field?   these become measures not dimensions.

[edwin]

its not letting me add the expressions

[edwin]

if(chan='1SA', val) as [Value of Debits],
if(chan='1SA' and Type ='1', vol) as [Fin vol],
if(chan='1SA' and Type ='2', vol) as [non Fin vol],

[edwin]

in your chart you just sum the measures

hi Edwin,

thank you for your reply.

I am not understanding...do you add your 'IF" statements in script?

Thanks

[edwin]

just add the if statements in your load script
