STEP function

[LBD]

I used the step function to show an increment of 620 every month, but it seems to just show me a value of 620 every month and not an increment.

in the function i've used an initial value of 3800 and then a step funtion of STEP(620, 1)... is there a way to show an increment of 620 and not just 620 every month in the model?

Use the RAMP function - combine it with MODULO if your model has a TIME STEP less than 1 month.
