I have a process builder on Account that updates values of its child record from Address object.
Field Zip in address need to be updated with concatenate value of Zip_vod__c + '_xxx'. Formula :
[Account].Address_vod__c.Zip_vod__c & '_XXX'
But in the formula to set this updated value error the following error occurs :
'The element has an invalid reference to "Account.Address_vod__c.Zip_vod__c". '
This formula allows to select field from Account object but not from its child object on which record update is needed. Please let me know if it is at all possible or not.
