Marketo Sync User Permission Issue During Lead Merge in Salesforce

[Kajal_Aneja1]

Hi Folks,

I'm encountering an issue while merging leads in Marketo. Has anyone faced this before or knows how to resolve it?

Error:
"Failed merging lead in Salesforce due to "Error: insufficient access rights on cross-reference id". The Marketo sync user does not have the needed permissions on the cross-referenced objects to successfully complete this operation. Please correct this. Please reach out to Salesforce support if further help is needed."

The message is pretty self-explanatory, right? You can’t perform the merge because the SFDC API user doesn’t have sufficient permission to both the source and target records. Talk with your SFDC admin to see if they’re willing to change that (some admins lock that down on purpose because it has implications for lead ownership, etc.).
