Salesforce - Marketo sync failed due to field not being visible in SF sync user

[Stephen_Graing1]

Hi all

Issue is as the subject line. The sync between our Marketo and Salesforce sandboxes, which was previously working fine, has stopped. The error appearing seems straightforward enough:

The following fields are hidden from the Salesforce sync account markto@xxxxx

Object

Event_History

Field

SystemModstamp

Edit the visibility permissions in Salesforce for the required fields.

However, the feedback from our Salesforce admin is as follows:

There isn’t actually an object called Event History, its an additional field history tracking you can enable. Mod stamp is a standard field. Its very strange that the field is suddenly not available to the sync, as it’s not a field that is touched.

We also have three event objects all called event, 2 custom and 1 standard object.

Can anyone advise what fields/objects we need to make visible in order for this to work? I've had a look at similar posts on the forum and there seems to be a consensus that the Marketo error is misleading and this field could actually be something else. Unfortunately we don't know what!

Any help or advice much appreciated.

Thanks

I would open a support ticket

Marketo doesn't support History objects; unfortunately it doesn't stop you from trying. Disable your Event History objects from syncing in the SFDC Custom Object menu in Admin and the errors will go away.
