My Project uses the following workflow:

I want to transition an issues to Rejected if at if at least one rejection is received. 

I also want it to transition to Approved only if All have accepted. 

 

Preliminary Concepts

The options impacting customer requirements include:

  • the Enable automatic workflow transition based upon conditional and unconditional minimum required approbations/rejections 
  • the Automatic workflow transition on approving
  • the Automatic workflow transition on rejecting
  • the Transition on rejecting 
  • the Minimum Required rejections based on  condition

Solution 

 Customer requirements have been satisfied through the configurations showed above:

  • turn ON the option Enable automatic workflow transition based upon conditional and unconditional minimum required approbations/rejections on the Global Configuration screen

  • create a Conditional Rule always true → status != approved
  • Setup the Approval Mapping advanced setting as follows
    • Automatic workflow transition on approving: ON
    • Automatic workflow transition on rejecting: ON
    • Transition on rejecting:  Reject 
    • Minimum Required approbations/rejections:
      1) If Always True then it's required the rejection of 1 Approval/s

 

Finally, the Approval Mapping displays as follows:
