Adobe Exam AD0-E556 Topic 8 Question 16 Discussion

Building two Custom Objects, one called ''Products'' and one called ''Services'' to link onto Person with relevant fields is the best way to push the data into Marketo Engage. This way, you can store multiple records of products and services for each person, and use an Email Scripting token in the email to personalize it for each recipient. Syncing this data on the ''Person'' level in a number of fields for ''Product'' or ''Service'' would limit the number of products and services you can store for each person, and would require building Segmentations for Product and Service and adding Segments into the Email as Dynamic content for personalization. Creating a maximum of 3 fields for each piece of data for both Products and Services onto the ''Person'' level would also limit the number of products and services you can store for each person, and would require adding each field into Email Scripting tokens then use to turn the module on or off if they have less than 3 products.
