I used the following logic when developing the workflow process； 1）Create process logic to link Event and Admin Account 2）If anyone submit or approve a request , I change the Event Process : from ” submitter account” to “Line Manager Account” Through this microflow, I realized the circulation of approval process among different roles, but the approval process can only flow from single person to single person; Imagine the following scenario： Submiter group(2-3) 、 Linemanager Group(2-3person)、General Manager If one submitter submitted an application, every LineManager could examine and approve this request； After the approval of the line manager who logged in to the system at the earliest, other managers cannot approve; As long as one of the line managers approves, the approval process will be transferred to the general manager； How to implement group to group workflow?
