Build your own Power BI dashboards from REPORTING.CZ data

Power BI is one of the most widely used tools for data visualisation and analysis. Many organisations, however, face the question of how to connect it effectively to corporate data warehouses so that reporting is not limited to one-off analyses but is based on centrally managed, consistent and reliable data. RCZ covers the entire data workflow – from collection and transformation to creating outputs. The key element is the data warehouse (DWH), which ensures data management, historisation and consistency. For Power BI users, RCZ also offers a dedicated Power BI connector that enables easy and secure connection to the RCZ data warehouse without complex configuration.

This approach lets organisations take advantage of the full flexibility of Power BI while building on stable, verified data. If you already use Power BI and are looking for a reliable way to connect it to your reporting, our connector is the optimal path.

Below, we explain how Power BI connects to RCZ, the key aspects of data model design and the benefits of this solution for high-quality, sustainable reporting.

The role of the data warehouse (DWH)

The foundation of effective reporting – whether in Power BI or RCZ – is a data warehouse (DWH). It ensures that data is centrally managed, historised and ready for systematic analytics. Without a good DWH, any reporting becomes complicated, error-prone and harder to maintain.

How to connect Power BI to RCZ

To make your work as easy as possible, we have developed our own Power BI connector that handles the connection without complex setup.

Building the data model

Correctly identifying tables and the relationships between them is essential for building a good data model in Power BI. The success of all reporting depends on careful model design – a poorly structured model can lead to incorrect or misleading analysis results.

We can help you with this process through a consultation, a practical demonstration or detailed documentation. To get to grips with the topic yourself, we recommend our documentation, which contains systematic procedures and concrete examples of implementation.

To build aging reports for invoices, receivables and payables, at least the following tables must be available (see the image below). These tables are the key building blocks of the model – without them, it is not possible to accurately calculate due dates, payment delays or the current status of payables and receivables.
