EBS R12 Error in AME workflow when new approver is added

 Solution: 

1. Remove the employee name in the fnd_user form and add again and save.

2. Check tables wf_roles, wf_user_roles compare with the working employee.

3. In the AME Approval list check if the approvers are coming dynamic, then change it to the static and all the approvers.

Clear cache and test again.
