We have Person Accounts synced with MC from SF CRM, the Person Account record Id's are marked as Subscriber Key and they all starts with "003". Now, I need to update those person accounts in Salesforce using AMPscript through Cloud Page, the email sends record Id to cloud page and AMP script tries to update the record in SF based on the same Id. Problem here is, AMP cant find this record since the Id starts with "003" (where actual Account Id starts with 001).
Is there any way to update those Person Accounts using Id which starts with "003" ?
