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 )
