Syncing to User Lookup Fields in SFDC

[Jace_Garside1]

We have a custom user lookup field in our Salesforce environment.  That field is integrated with our Marketo environment.  In Salesforce, that field shows the user's name, but in Marketo, the user ID is populated.  Is this a normal/expected outcome?  Is there a way to have the user's name populate without having to create a formula field in SFDC?

Based on the conversation below, looks like a formula field is required to populate the user display name in Marketo.

This could work I believe: You can develop apex triggers to populate the custom field in sfdc that will sync back to marketo normally.

Hello @Jace_Garside1 

Is this a normal/expected outcome? 

Yes, when connecting tables the default way it to use Foreign Keys and Primary keys so that is why you see an integer. 

Is there a way to have the user's name populate without having to create a formula field in SFDC?

Yes, try the following to output a name (text) value:  https://developer.salesforce.com/forums/?id=906F0000000AxcXIAS
