It sounds like you are able to do the first step of changing the stage. To go to the second step on the change back you could probably do the following.
Update the start when condition on the step to have a condition that would evaluate to true only if it wasn't already processed. Then if you do a change stage back to the first it should skip it based on that behavior.
I'm aware of what you are telling.it will only prevents the user from transition to next step and it validates the fields on a form.I need to a transition from a particular step in one stage to another step in different stage
Here I'm in Define solution step in solution design stage and it has Yes or No Buttons.
Condition 1:If I select Yes it should go to next stage Query response.Okay with that.
Condition 2:If I select No it should go to next step in the same stage.No issue with that.
Condition 3:Now selecting Yes in solution design stage advances to the Query response stage.After performing last step Response review it has to go to Estimate effort step in Solution design stage.This is my case flow and I'm facing issue with this.
Do I have to modify the case life cycle or stick with the same?!
Hope this could help you to understand better.tried so!
