Hey,

I would like to filter an Order dataset on only the orders of the last 10 months.

Is this possible with Foundry Rules ? Can we have functions-based filters ?

Or do I have to precompute the date from 10 months ago in the dataset ?

Thanks,

Julien

This is possible using the “expression” board in the foundry rules editor.

For example, `add_date(current_date(), -7)` will generate the date from now minus 7 days. See https://www.palantir.com/docs/foundry/contour/expressions-syntax/ for the full syntax enabled in the expression board.
