Merge a Marketo Field with a SFDC Field – Deep Dive

Merging fields is a trick Marketo support and services can do to combine a Marketo only field with a SFDC field.





Marketo won’t be able to merge a field if the type doesn’t match the field you are merging with. Thus, they can only merge a string field with a string field. They won’t be able to merge a date with a datetime field.



They won’t be able to merge a field if it is in use.



Merging fields starts with selecting which field (Friendly name will remain).



When they merge fields you need to determine which field you are merging with, it is called this the Target Field. Target is the field which will remain after the merge. You also need to choose which value will win.



Merging fields may take some time and once started it cannot be canceled. Once the merge is completed the merged field will no longer exist in Marketo.



Important: If you are in the process of integrating/syncing SFDC with Marketo for the first time, I highly recommend you merge the fields before you start the record sync between SFDC and Marketo. Since merging fields takes time I recommend building this task into your implementation schedule.
