I have a custom object called
Gym_Issue that has a field called
Gym_Issue Name (a default field created by Force platform) and a Contact lookup field.
I would like to populate Gym_Issue Name by code (or using workflow) so that its value is a concatenation of
Contact.Lastname + Today's Date (YYYY-MM-DD-HH24-MM).
I do not want autonumber ID for the column Gym_Issue Name.
What is good way of achieving this ?
