In this section we provide an overview of the Data Health Check bookmarks.

Validating Correctly-Loaded Data with the Data Health Check Dashboard

The FRTB Accelerator comes with a set of pre-defined bookmarks visualizing the risk metrics.

After you launch the application, click the bookmark icon on the left navigation bar to open the “Dashboards” tab. This presents the list of bookmarks available to you. In this tutorial we will talk about the Data Sanity Check summary bookmark:

Bookmarks

SA Inputs dashboard

In this version of the FRTB Accelerator we have pre-configured views for checking the “SA Inputs”.

Note Although this dashboard helps you identify potential issues faster, checking these views does not guarantee that all input fields are populated correctly. The views in this bookmark can help to reveal file parsing errors and provide a quick input data summary.

Tab What to check
Trades Review the total number of distinct trades and compare against that expected for different risk types.
Sensitivities Compare the delta, vega totals.
The totals must match the input files. If not, check for duplicate records, invalid static data or the FX rates you are using.
Qualifiers Review the counted number of different underlyings for non-GIRR risk types and the number of different currencies for GIRR. These attributes represent the main component of the risk factor.
Compare the counts against the expected.
Notional RRAO Review the notional amounts sourced from the Trade Attributes file.
DRC tab Review the Gross JtD summary for the DRC SA calculations.

Tip To limit the scope of data and simplify analysis and investigation, consider setting a filter on a particular trade, book or attribute.

Further data validation

You may want to validate input data further or investigate a specific issue. For this, use the bookmarks in the “Basel Framework” folder as a starting point. They provide views for each calculation step from the input data through to the risk charge and you can drill down further to trades and other dimensions or attributes.

If you have loaded the data using the CRIF Format, you can find the mapping between the CRIF fields and our data model in this section: FRTB Accelerator Interpretation and Implementation of BCBS 457.
