Formulas provide you with the means to calculate unique values in QlikView and then export them from QlikView into your reports. Formula use in NPrinting will be explored in this tutorial. It is presumed that you are familiar with more the fundamental aspects of Excel template creation using NPrinting. If not, see How to Create Excel Reportsand How to Create One or More Levels in Excel Reports.
First of all, formulas must be QlikView formulas, i.e. they must use reserved words as defined for QlikView and according to QlikView syntax. Formulas to be used in NPrinting must evaluate to a unique value. Please notice that =getCurrentSelections() returns a unique string - it's composed by merging the selected values with a separator, but it's a single string so this function is admitted.
The series of formulas that will be created here are simple because the objective is to show how to use them in NPrinting and we do not want to distract your attention from this. The formulas will be employed with and without numerical and time formatting. NPrinting sends the formula to QlikView for evaluation and any numerical or time formatting must be applied by QlikView at the moment of evaluating the formula to its unique value. The value is exported from QlikView with whatever numerical or time formatting that has been applied and will fail to be altered by any attempt to apply similar formatting in the template. The result of using formulas in levels and pages will also be demonstrated.
