We have a issue that keeps coming up. Lead Source. Currently we have a list which is used for original lead source which pulls into SFDC. We are finding that when the lead is converted to a opp the lead source is not carried over and changed by the Sales Rep. We want to add in original and most recent lead source into SFDC eventually however we do not have admin rights to do so. We are now finding that our lead source on the lead is over writing in some cases and cannot figure out why? Here is a example of a lead source that has changed. We assumed that it was only changing it if lead source was empty but it seems it is overwriting it all together?
Any ideas how we can lock it down, through Marketo?
