- About My MATRIXX Help
  My MATRIXX Help provides information about My MATRIXX, a web application that offers a central location for creating pricing plans and configuring MATRIXX charging and rating behaviors. My MATRIXX is intended for pricing administrators who are responsible for creating and maintaining pricing plans and for IT administrators or developers who configure the rating and charging behavior of the online charging system.
- Introducing My MATRIXX
  The following information describes the My MATRIXX interface.
- Using My MATRIXX
  You use My MATRIXX to validate and compile the pricing configuration file, compile pricing, and set up and manage user roles and domains; create and manage catalog items and catalogs, manage eligibility features and rules, and manage the Normalizers interface; create and manage balances, pricing, offers and bundles, general components, and application-related components; and policies for charging and rating. Use General Configuration to create components that support pricing items and charging functionality such as announcements pricing components, attribute definitions, denial codes, products, decision tables, Final Unit Indication (FUI) profiles and generators, general ledger transaction types, notification profiles, normalizer templates, and subscriber information query actions, profiles, and generators.
- Home Menu
  The following information describes the tasks that can be performed using the My MATRIXX Home menu.
- Catalog Configuration
  Catalog Configuration contains the Catalog Items interface that you use to create, change, or delete catalog items; the Eligibility interface to manage eligibility features and rules to determine whether a subscriber, group, or device is eligible for a catalog item; and the Normalizers interface you use to edit normalizers.
- Charging Configuration
  Charging Configuration has the interfaces you use to create and manage balance, pricing, product offer and bundle, general, and application-related components.
  - Balance Configuration
    Balance Configuration contains interfaces you use to create and manage price components including aggregation selectors, balances and balance classes, balance state update profiles and components, meters, and rollover profiles and components.
  - Pricing Configuration
    Pricing Configuration contains interfaces you use to create pricing plan components. Pricing plan components managed through this interface include decision tables, finance and service contracts, filters, price components including charges, discounts, grants, refunds, and forfeitures, and rate tags.
  - Offer and Bundle Configuration
    Offer and Bundle Configuration contains interfaces you use to create and manage pricing and rating components including bundles, offer priority generators, product offers, and product service types and attributes.
  - Normalizer Configuration
    Normalizer Configuration contains interfaces you use to create and manage normalizers, normalizer templates, and normalizer value lists.
  - Tax Configuration
    Tax Configuration contains interfaces you use to create and manage tax classes and selectors, and US taxation. You must have the Manage Tax domain user role to enable this menu.
    - Tax Setting
      Use Tax Setting to enable US taxation and select the provider type.
    - Tax Selectors
      Tax selectors enable MATRIXX Engine to dynamically select a tax (or a set of taxes) to apply to charges based on specified criteria. Tax selectors define the criteria and indicate the tax selection profiles that apply to the criteria. The tax selection profile contains the tax class identifiers of the tax (or set of taxes) to apply.
      - Tax Selection Profiles
        When you want MATRIXX Engine to select which taxes to apply to charges based on the presence of one or more criteria associated with the charges (taxes to be applied are selected dynamically), you create a tax selection profile to contain the list of the tax classes to apply. A tax selection profile is used in a product offer application profile using a tax selector. Tax selection profiles are reusable pricing items that can be contained in one or more tax selectors.
      - Tax Selector Components
        Tax selectors are pricing items that are used for selecting a tax selection profile based on specified criteria.
      - Tax-Selector Component Corrections and Revisions
        Tax selectors and tax selection profiles are revisioned pricing items. You can make corrections to existing revisions or make new revisions.
    - Tax Classes
      You can set up tax classes that determine either the percentage rate for taxes or a fixed tax value, and how taxes are to be reported in general ledger (GL) postings. Tax classes are referenced from product offer application profiles; the profiles specify how taxes are to be calculated for charges owned by the offer on a per charge application type basis.
    - US Taxes
      US Taxes provides a dashboard showing a list of pending and completed US tax compilations. Use this view to import, manage, download, and delete US tax compilations.
  - General Configuration
    General Configuration has interfaces you use to create pricing plan components. Pricing plan components managed through this interface include announcements, product and system attributes and definitions, currency codes for rate tables, denial codes, field definitions for use in normalizers and rate tables, Diameter Final-Unit-Indication (FUI) profiles and generators, General Ledger (GL) transaction types and info generators, grace period profiles, languages, notification profiles, parameter definitions, pre/post-rating profiles and generators, SH Repository data, Subscriber Information Query components, tax classes for offer categorization, usage quota profiles and components, purge profiles, virtual fields, and usage triggers.
  - Application Configuration
    Application Configuration components are used by My MATRIXX for creating pricing plan items and are used by MATRIXX Charging Application and MATRIXX Policy Application for charging and rating.
- Policy Configuration
  Policy configuration components are used by MATRIXX Charging Application and MATRIXX Policy Application for charging and rating.

Tax Selectors

Tax selectors enable MATRIXX Engine to dynamically select a tax (or a set of taxes) to apply to charges based on specified criteria. Tax selectors define the criteria and indicate the tax selection profiles that apply to the criteria. The tax selection profile contains the tax class identifiers of the tax (or set of taxes) to apply.

Note: You must deselect Use US Tax on Edit Tax Setting to enable Tax Selectors.

When you define how taxes are applied to charge price components contained in a product offer (by adding an Application Profile in the Tax/GST tab of a product offer revision), you can specify whether to use a tax selector for determining the taxes to apply. Tax selectors configuration is set on a per charge application type basis (usage, purchase, first-use, recurring, auto-renew, or cancel charges).

Note: If the application profile has a tax selector set (the TaxSelectorId field), the tax class (TaxClassIdArray field) in the application profile is ignored.

Tax selectors define the criteria for choosing a tax selection profile as a set of normalized values. During rating, the normalizers associated with a tax selector are used to compare one or more parameters to a value and when MATRIXX Engine finds a match, it selects an index in the tax-selector matrix, which leads to the tax selection profile (result) to apply.

Normalization on the following fields can be used for tax selectors:

Fields in the network message
Fields in the product offer custom extension
Fields in the bundle custom extension (if the product offer is part of a bundle)
Fields in the purchased offer (or purchased bundle) custom extension
Fields in the subscriber MATRIXX Data Container (MDC)
Fields in the device MDC
Fields in the group MDC
Fields in the subscriber wallet or group wallet database object; specifically: TaxLocation, TaxStatus, and TaxCertificate

For more information about normalization, see the discussion about normalization in MATRIXX Pricing and Rating.
