Multilevel Leave approval is not working

After following the link mentioned on the https://docs.erpnext.com/docs/user/manual/en/setting-up/workflows

But still it is not working anything i am missing?

What do you mean by not working? People with the respective roles aren’t able to approve?

Also, do post the screenshots of the transition and states so members can review the same and assist further.

Find the screenshot and do let me know if i am missing something/

Is there any impact of reporting head and leave approve on employee profile

What version are you using?

Make sure to also set up the approvers at department level or employee level correctly:

Thank you very much, after setting of employee leave approvers it is working fine.
