Perhaps this is possible and I do not know how to do it. I just created CR 2161 - CR 2161 - Please provide materialized view / formula fields in the Ninox API as well as expose to Integromat.
A very simple example is an Invoice Line Item that has quantity and an item Id that looks up a price based on a date range and provides a calculated amount. This formula field does not appear in Integromat nor in the Ninox API.
As a work around, I have hidden fields that triggers update.. Or am I missing something?
