Master data records streamline data sharing and facilitate data transactions between teams and throughout an agency. Master Data Terms and Concepts This section contains information about terms and concepts related to master data entities. Types of Master Data Entities There are two groups of master data entities: Master Data Group Description Agency Group Advertising agencies, their business structures, and their client relationships. Vendor Group Who is paid for a media activity, who runs the activity, where the activity is run, and the relationship between these three entities. Agency Group Entities Entity Description Enterprise  The highest-level entity within the OneStrata platform.  Enterprises are configured and managed by OneStrata.

Vendor Group Entities Entity Description Payee An entity that is paid for media activity and is part of the vendor structure (Payee, Order Partner, and Supplier). Order Partner  An entity that processes orders and is part of the vendor structure (Payee, Order Partner, and Supplier). Supplier An entity that runs media or non-media activity and is part of the vendor structure (Payee, Order Partner, and Supplier). Contract The record that links one Payee, one or more Order Partners, and one or more Suppliers. Types of Order Partners The type of an Order Partner affects how the Order Partner receives and approves an order. Order Partner Type Description External Order Partner An Order Partner configured for external confirmation ; the vendor confirms or declines the order outside of OneStrata. For example, over email. In-System Order Partner An Order Partner configured for in-system confirmation ; the vendor confirms or declines the order in Vendor Inbox. Internal Seller Order Partner The internal seller workflow is a gated feature and not enabled by default. If the internal seller workflow is not enabled, internal seller Order Partners cannot be created. To enable this feature, contact your OneStrata representative.   An Order Partner configured for in-system confirmation and the internal seller workflow. Auto-Confirmation Order Partner An Order Partner configured for auto-confirmation ; all orders are automatically approved once sent. Types of Suppliers The type of Supplier affects the type of Cost Line that the Supplier can be assigned to. Supplier Type Description Media Supplier A vendor that provides advertising space. Media Suppliers can only be assigned to media Cost Lines (a Placement, Media Package, or Cost Package). If the Supplier of a Fee record is a media Supplier, when the fee is applied to a campaign or Cost Line, the resulting Fee line is created in the Media section of the Schedule grid. Non-Media Supplier A vendor that provides a media activity-related service, like ad serving or tracking, but does not provide the actual media advertising space. Non-media Suppliers can only be assigned to non-media Cost Lines. If the Supplier of a Fee record is a non-media Supplier, when the fee is applied to a campaign or Cost Line, the resulting Fee line is created in the Non-Media section of the Schedule grid. Validity Dates The Valid From and Valid To fields on a master data record define its validity dates. In turn, the validity dates affect the campaigns or Cost Lines that the master data entity can be assigned to. Master Data Entity Validity Dates Agency The Agency can only be assigned to campaigns that start and end within the Agency record's validity dates. Business Unit The Business Unit can only be assigned to campaigns that start and end within the Business Unit record's validity dates. Client Group The Client Group can only be assigned to campaigns that start and end within the Client Group record's validity dates. Client The Client can only be assigned to campaigns that start and end within the Client record's validity dates. Product Group The Product Group can only be assigned to campaigns that start and end within the Product Group record's validity dates. Product The Product can only be assigned to campaigns that start and end within the Product record's validity dates. Payee Payee records do not have validity dates. Order Partner Order Partner records do not have validity dates. Supplier The Supplier can only be assigned to Cost Lines that start and end within the Supplier's validity dates, for a specific Contract. Note: Supplier records do not directly define validity dates; a Supplier's validity dates are defined per Contract on the Contract record. In other words, a Supplier can be in multiple Contracts and have different validity dates for each Contract. By default, the Supplier's validity dates for a Contract are the same as that Contract's validity dates, but can be customized when creating or editing the Contract record. Contract The Contract can only be applied to Cost Lines that start and end within the Contract record's validity dates.
