I have a Contact(Parent) and Prorgam Enrollment(Child). 

A contact can have multiple Program Enrollments. There is a date field on the Program Enrollment. 
For example, If a contact has 4 Program Enrollments and if I update the date field in One Program Enrollment, the same date should be updated in the other program enrollments too?? 

Can I achieve this through workflow rules? or process builder with out any code?


I appreciate your time and Help!
