Jon Foy Need Help Writing A Trigger to run a Roll up Summary on a Cross Object Formula Field
I believe I've ran into a limitation in SF, in that I cannot create a roll up summary on a cross object formula field. Here's my scenario:
We have a custom Object: TimeSlip__c, which contains a field "Billable_Amount__c" that is a cross object formula. It take the "Rate__c" from another related object (Case_Resource__c) and multiplies it by the number of hours entered on the TimeSlip (Total_Billable_Time__c).
I'm trying to create a rollup summary on the Case Page that calculates the toal Billable Amount from all timeslips by rolling up the "Billable_Amount__c" field, but SalesForce isn't giving me this option.
I've been told I can achieve this with a trigger, and need some help writing the Apex Code.

Trigger timeSlipTrigger on TimeSlip__c (after insert, after udpate){
Integer rollUpAmount;
for(TimeSlip__c ts : Trigger.New){
if(ts.Billable_Amount__C != Null){
rollUpAmount += ts.Billable_Amount__c; //Suppose you want to add all in Rollup logic
}
}
if(rollUpAmount != Null){
Case c = [select id, name, rollupfield from case where id =: ts.case__c.id];
c.rollupfield = rollUpAmount;
update c;
}
}
trigger UpdateCaseBillableAmount on TimeSlip__c (after insert, after update) {
Integer rollUpAmount;
for(TimeSlip__c ts : Trigger.New){
if(ts.Billable_Amount__C != Null){
rollUpAmount += ts.Billable_Amount__c; //Suppose you want to add all in Rollup logic
}
}
if(rollUpAmount != Null){
Case c = [select id, name, total_billable_amount__c from case where id =: ts.case__c.id];
c.rollupfield = rollUpAmount;
update c;
}
}
i'm getting the following errors:
"no such column 'name' on entity 'Case'."
and if I remove 'name' i get this:
"variable does not exist: ts.case__c.id @ line 9 column 79
