Smart IF

[jcarville]

Hi,

I'm looking for a smart way, using a measure, to assign a discount value against a customer.

I have 2 tables Transactions and DiscountCriteria. I would like to SUM the Tons for each Company, and then depending on the Total SUM, apply a discount e.g. Company A have 1.8 Tons so they would get a 0.03 discount (discounts are all greater than).

I know I could do this by writing a large IF measure, but I'm wondering if there was a better way to do this.

Transactions:

Company	Date	Tons	Value
A	01/01/2016	0.5	35
A	01/03/2016	1.3	100
B	01/03/2015	3	256
C	01/04/2015	4	354
D	01/03/2015	1.1	123

DiscountCriteria:

Tons	Discount
0.2	0.01
0.5	0.02
1	0.03
3	0.04
5	0.05

Thanks,

Jake

The smarter IF is called SWITCH.

Thanks @Greg_Deckler, I've gone with the tried and tested SWITCH(TRUE()) formula, how could I have forgot about this beauty:

Discount - Volume =
SWITCH (
    TRUE (),
    AND ( SUM ( SAGE_Extract[Tons] ) > 2, SUM ( SAGE_Extract[Tons] ) <= 5 ), 0.01,
    AND ( SUM ( SAGE_Extract[Tons] ) > 5, SUM ( SAGE_Extract[Tons] ) <= 9 ), 0.02,
    AND ( SUM ( SAGE_Extract[Tons] ) > 9, SUM ( SAGE_Extract[Tons] ) <= 12), 0.03,
    AND ( SUM ( SAGE_Extract[Tons] ) > 12, SUM ( SAGE_Extract[Tons] ) <= 14), 0.04,
    SUM ( SAGE_Extract[Tons] ) > 14, 0.05
)

This has raised the next issue for me. Every row in the Transactions table has a currency against it e.g. "USD" or "GBP". I would like to add something like this to my measure:

If the currency = "USD" then multiply the discount by my Currency Conversion Rate measure.

Any thoughts?

You can create another measure 

AdjustedDiscunt =  if (currency = "USD", [Discount - Volume ]*[Currency Conversion Rate],[Discount - Volume ] )

Just add table names to above formula

@NipponSahore, I'm pretty sure that formula only applies to a calculated column, not a measure.

@NipponSahore, I used a 2nd measure similar to this:

Measure = IF(HASONEVALUE(SAGE_Extract[Symbol]),IF(VALUES(SAGE_Extract[Symbol]) = "USD",[Discount - Volume]*'Exchange Rate'[Exchange Rate Value],[Discount - Volume]))

I might re-visit this in the future to see if I can combine the 2 measures into 1, but I am happy for now.
