Overview

Open the Data load editor and add the load script below to a new tab.

The load script contains:

Financial data contained in a table called RangeTab3.
The use of the RangeXNPV() function to compute net present value.

Load script

RangeTab3:
LOAD *,
recno() as RangeID,
RangeXNPV(DiscountRate,Value1,Date1,Value2,Date2) as RangeXNPV;
LOAD * INLINE [
DiscountRate|Value1|Date1|Value2|Date2
0.1|-100|2021-01-01|100|2022-01-01|
0.1|-100|2021-01-01|110|2022-01-01|

Results

Load the data and open a sheet. Create a new table and add these fields as dimensions:

RangeID
