Before migrating or upgrading Advertising Sales Management (ASM) in Salesforce Media Cloud, it's crucial to safeguard existing customizations and modifications. Taking a backup of any older ASM components that have been customized or modified ensures that custom functionalities and integrations are preserved during the upgrade process. This step is essential to avoid data loss and to maintain the integrity of custom workflows, processes, and configurations that have been tailored to the business's unique requirements.

To most efficiently create digital advertising products that share a common set of characteristics, a product manager should use a product family (B). Product families in Salesforce Industries allow for the grouping of related products, enabling the manager to define shared attributes and characteristics at the family level, which then applies to all products within that family. This approach streamlines the creation process and ensures consistency across similar advertising products.References:

In Salesforce Media Cloud, the account object can be customized to represent different entities involved in the media and advertising ecosystem. The three record types for the account object include: Agency Account (A), Advertiser Account (B), and Publisher Account (C). These record types help in organizing and managing relationships and interactions with various stakeholders in the advertising process, such as agencies that represent advertisers, the advertisers themselves who are the clients looking to promote their products or services, and publishers who own the media space where the ads are displayed.References:

The Quote object serves as the core representation of a media plan in ASM. Quotes capture the details of proposed ad buys and are central to sales processes. The Media Plan object is more of an extension or custom entity, but Quotes remain the foundational object.

When proposing the use of JSON-based mapping over object-based mapping for contract templates, a consultant should keep in mind the following features:
JSON-mapping allows for filtering individual line items or repeatable content items to display in a document, but object-based mapping does not: This feature provides greater flexibility in customizing the content that appears in the document, allowing for more targeted and relevant information to be included.
The consultant can use the item section for any type of item list, not only for line items: This versatility enables the inclusion of various types of data lists in the document, beyond just standard line items, enhancing the document's comprehensiveness and relevance to the specific use case.
