Reg: how to make the lookup field as required?
how to make the lookup field as required if the value of other field is not blank ? those two fields belongs to same object.. is it possible with the help of validation rule?
ISBLANK( candidate__c )
This will make the Field not to allow the null values
Let say Lookup field is "Look_Up__c" and other field is "Supporting_Field__c".
AND(NOT(ISBLANK(Supporting_Field__c)), ISBLANK(Look_Up__c))
Then,
throw a validation error on Look_Up__c field saying that you need to fill this field.
Thanks,
