SEI @@curdate use into formula.

Hi everyone, 

I'm trying to have a SEI view that shows me a week's window of information in a way that the date is variable and not fixed using an specific date in the filter formula. I've tried to use the @@curdate variable is seems is not compatible with mathematical operators.

This formula works to shows everything until current date;


This formula is intended to show me everything until next week (open work orders), but it shows an error.

The idea is to have SEI screen that are open in the shop floor as a visual aid of status of material pending to make.
