I think Marketo is changing lead owner when it shouldn't

[Anonymous]

I'm having an issue where new leads are getting assigned to me in our Salesforce instance instead of the default lead owner (not me). The scenario is that we have leads being created via API when users register for our software. The API doesn't specifiy a lead owner, leaving it to Salesforce to determine. I have the default lead owner set up in Salesforce and in normal situations when a lead is created the default owner is assigned. But with the leads being created via API for some reason I become the owner. After searching all over Salesforce I finally had the idea to check Marketo activity logs. From the logs it appears as if Marketo is the one assigning the lead to me. Here is the first three log entries from one such lead:

Event ID	Date/Time PDT	Activity Type	Detail
48178311	2013-03-20 09:54:00	Change Data Value	Changed Sales Lead Owner from [null] to "Leif Espelund"
48178312	2013-03-20 09:54:00	Change Owner	Leif Espelund
48178151	2013-03-20 09:53:48	New Lead	Lead name: "Florian [not provided]", source: salesforce.com

Am I correct in reading that those Change Owner and Change Data Value events are Marketo Generated?

Most likely the Change Owner and Change Data Value come from SFDC because the last column is empty. To know for sure, double click the activity and you will see the 'source'. If it says "synced from salesforce.com" you know for sure

Well I didn't include that column because it was empty, so I guess that answers my question. Back to the drawing board.

Leif,

Interesting question. To determine this, we need to see the "campaign type" column as well. In Marketo, all flows are done in campaigns.

My hunch based on your log above is that all 3 activities are triggered by the initial sync, in other words, the SFDC sync is changing the values.

See below and note that only activities with a campaign associated (right column) are done by Marketo.
