Hi I have created a custom field of type formula field basically to fetch the Created By + Created Date into Markeo. But this field does not appear in Marketo after next Synchronization run by Marketo. I have applied the same logic 6 months ago to fetch the Account Record Type Name into Marketo using custom formula field and it worked. I am surprised why is the same not working now. Kindly help. Thanks

Marketo records are updated by SFDC when the system mod stamp (last modified time) on a record updates.Formula fields do not update the last modified timestamp on a record. They are evaluated everytime ar record is opened.For more informationhttp://community.marketo.com/MarketoArticle?id=kA050000000KzYqCAKYou should see that all those 44 records that have a value have a last modified stamp that equals a time later than when you created the field, that is why they were picked up by the background sync process.You may wish to consider triggering a mass update of all lead records via the data loader:http://community.marketo.com/MarketoArticle?id=kA050000000L5z1CAC
