Question 79 - Certified Marketing Cloud Account Engagement Specialist discussion

According to theSalesforce documentation, if Salesforce has a custom field of the same name on Leads and Contacts, Marketing Cloud Account Engagement pulls the field name from the Lead field. A custom field is a field that is created by the user to store additional information that is not available in the standard fields. A custom field can be created and managed by the administrator in the Admin tab in Marketing Cloud Account Engagement or Salesforce, and it can be synced between the two platforms. A custom field can have the same name on different objects, such as Leads and Contacts, but it can have different values or settings. If Salesforce has a custom field of the same name on Leads and Contacts, Marketing Cloud Account Engagement pulls the field name from the Lead field, as it is the primary source of the field name. Marketing Cloud Account Engagement does not pull the field name from the Contact field, as it is the secondary source of the field name. However, Marketing Cloud Account Engagement can pull the field value from either the Lead or the Contact field, depending on which object the prospect is associated with in Salesforce. For example, if Salesforce has a custom field called ''Industry'' on both Leads and Contacts, Marketing Cloud Account Engagement will pull the field name ''Industry'' from the Lead field, but it will pull the field value from either the Lead or the Contact field, depending on the prospect's record type in Salesforce.
