I did check there are no declare expressions configured in system on those fields. Also, i was able to see these values being updated in teacer in pre DT itself, Those updated values were not posted to clipboard. thease being posted after i submit that assignment only.
1) We are using screen flow. calling DT from connector will not be possible, but tried by adding utility prior to assignment and tried to call DT from connector next to utility.. but, the problem here is there is a chance that this count will get updated even after case reaches to assignment. at that time, we wont be getting updated value.
2) i tried calling save activity in pre DT, it is working fine and value is being updated in UI. but, unable to open assignment. since, save is being performed.
I can apply action-set, if that change is being performed through UI action, but i want to calculate these values(Total and Remaining rollout count) on load of screen (Doing pre processing of Flow action).
