## What If Parameter Help

We are trying to use the What-If function for the first time here.  We want to give our CFO/CEO the ability to change the budgeted Margin % to see how the bottom line is impacted.

But, we would like to be able to fo this for each different province.  This is all test data for roundness... but the use case is very real.  Thus far we have only been able to impact the entire Budget % Margin column, rather than focusing in on one margin adjustment.

Does any one have any suggestions on how we can make a work around here?

Hi, i suggest create one parameter to each Province.

After that create a Measure with a Switch Function to evaluate each case.

## Re: What If Parameter Help

Hey,

you have to provide three What-if parameter, one for each province.

Additionally you have to adjust you calculation, checking if one province is selected (in this case it just means used on rows), using this

```IF(HASONEVALUE('yourtable'[Province]),
var valueFromWhatIfParameter =
SWITCH('yourtable'[Province]
,"NB", get the value from that what-if parameter
,"NL", ...
,0
)
return
CALCULATE(something using valueFromWhatIfParameter )
)```

Hope this gives you an idea how to tackle your requirement.

## Re: What If Parameter Help

Hi @TomMartens,

First of all, thank you for helping me.

I tried this

```Budget%Margin = IF(HASONEVALUE(CRM_Dim_Projects[Province]),
var valueFromWhatIfParameter =
SWITCH(VALUES(CRM_Dim_Projects[Province])
,"NB", NB[NB Value]
,"NS", 'CM%'[CM% Value]
,0
)
return
CALCULATE(AVERAGE(CRM_Fact_SalesOpportunities[Budget%Margin])+valueFromWhatIfParameter )
)```

But it doesn't work. Could you have a look at my codes and tell me what is wrong please?

Hey,

currently I have no idea, but please have a look at the solution from @Vvelarde it uses a similar approach, maybe you can adapt to his approach.

Could you please explain this requirement in details? And share your sample table to test if I have any idea?
