I’ve got a uBAQ that processes using Advanced BPM Update. Is there a way that the BPM code can change a UD field on the BAQ to ‘true’? My idea is that once the BPM is done what it needs to do, I don’t want the result to show up again in the future. I have a criteria on the Phase Build to only show if this UD field is false.
