Property value not persisting across steps and getting recalculated on next step load

[RameshSangili]

@RanjithNarsini

I have a 2-step flow in a case type.

In Step 1, I am generating an ID using a preprocessing data transform and displaying it in the UI as read-only.

In Step 2, I am simply displaying the same ID (read-only) without any preprocessing or additional logic.

However, when I submit Step 1 and move to Step 2, the ID value is getting regenerated/refreshed instead of retaining the value generated in Step 1.

There is no preprocessing configured in Step 2, and I am not explicitly re-triggering the ID generation logic.

What could be causing the ID to refresh between steps? Can someone help me understand why this issue is happening

Move the ID generation logic to the Step 1 Post‑Processing Data Transform, or invoke a Utility shape and run the data transform before the assignment, so the value is written to the clipboard after the UI submission is processed, persisted to the database, and available for Step 2.
