reopening the task and continuing the flow from that step when approval is rejected

[Gaurav Vaze]

I have a requirement of catalog item
following is to be implemented

1st step is create catalog task---->if catalog task is closed complete--->step2
2nd step is approval-----> if approved----> step3 catalog task
approval on step 2 is rejected ----> reopen the first catalog task state to open and continue flow from that step
step3 closed completed ---> step 4 ask for approval---> if approved then final task
approval on step 4 is rejected ----> reopen the step3  catalog task state to open and continue flow from that step




right now I implemented as follows
step 1: create catalog task(wait condition applied)
if closed complete
do the following ...
                                   update record(step1 task state= open)
                                    ask for approval
until ask for approval is approved



same can be followed for the next step
but here the task is getting open even if it is closed and approval is approved


creating a task inside the do the following is not required thus how can I overcome this
Need help please

I appreciate your efforts
but this will not re-iterate through the flow

I have tried the 'do the following until'
sharing the ss of flow so someone may find it helpful

ignore the highlighted part

Mark it as helpful if someone is getting correct result
