Adding a fixed value crashes my measure

Hi,

I'm trying to add a fixed value to my GP Per Lift measure. The measure below works, but if i add a fixed value of 3.5 it crashes my report.

This measure has a fixed value:

The below measure crashes my report. 

Please find the link to my report below any help is much appreciated.

Returning constants from measures is generally a very bad idea. If you have 1000 customers 1000 products and 2 years worth of data (so 730 days) and you drag the product, customer and date onto a table with the operational cost measure the table will attemtp to return a row for every combination (so 1000 x 1000 * 730) which would be 730 million rows.

So I would suggest doing something like the following where you check if the measure is not blank before adding the constant value to it.

GP per Lift (excluding rent & doc) =
VAR _operationCost = 3
VAR _part1 = [Lift Rate] - [Disposal Cost per Lift]
RETURN IF( NOT( ISBLANK( _part1 ) ), _part1 + _operationCost )
