shrey.tyagi88@tcs.com Please help: Trigger to make an entry in Cust.Obj B when there is a change in feild of cust obj A
Hi,
I wanna write a trigger .This trigger gets fired when I change a field (a1__C) in custom object A.This trigger should write thje following message
" a1__c has been changed in A".This message is stored in notes feild (B1__c) of custom object B. Every time there is a change in A , a new entry is made in B. B has only one field i.e B1 which is of text area type.
Please help me on this it's urgent!!!!
Thanks
Hi shrey,
Hope this example helps you :-
trigger CaseTgr on CustObj (before update) {
if(trigger.new[0].a1__C!=trigger.old[0].a1__C)
{
ObjB B= new ObjB();
B.B1__c=" a1__c has been changed in A";
insert B;
}
}

Hi,
First of all you have to check old and new value of field of custom object A for before update event, if it is not equal to previous values, you can set a message if condition meet and assign the message to custom object field value for B.
You can use
trigger.new[0].CUSTOMOBJFIELD.adderror('custom object A has been changed in A');
Did this answer your question? If not, let me know what didn't work, or if so, please mark it solved.
You can write a workflow if your both objects are releated since trigger is not always a good solution.
