1.- Create an object called A, with a date field called DateA - Create an object called B, with a lookup field to A and a date field called DateB
2.- Create a trigger that will set the DateA field as the highest of the children's DateB field
3.- Create a VF page that will receive the id of an A object and will allow you to mass edit the DateB fields on the child B objects, in a table .
I have done the 1.st point, I have created an object called A with a date field called DateA and I have created another object called B with a lookup field to A and a date field called DateB. I learn triggers from youtube but this is something which I dont find anywhere,so I have difficulty at the 2nd and the 3rd point. Any suggestion or help would be much appreciated. Thanks in advance.
