How to Connect Your BI Tool to Your ERP Without Depending on IT

Most ERP systems store data in SQL Server, Oracle, or a cloud database. Most BI tools have native connectors to these databases. The gap between them is smaller than most businesses realize.

Here is the practical path to connecting your reporting layer to your ERP.

Step 1: Understand what you can access

Your ERP vendor documentation will describe what database access is available. Some vendors support read-only connections to the underlying database. Others require you to use their certified connector or API. A few restrict direct access entirely.

For the major platforms: SQL Server-based ERPs (IQMS, Dynamics, older SAP installations) generally allow direct database connections. Plex provides a certified connector program. Business Central supports both a connector and direct API access. Cloud-native systems vary.

Step 2: Set up a read-only connection

Never connect your BI tool directly to your production ERP database with read-write credentials. Query load from analytical workloads can affect operational performance. Use read-only credentials, and consider a read replica or reporting database if your ERP supports it.

Step 3: Find the tables you need

ERP databases are large and complex. You do not need to understand all of them - just the tables that hold the data you want to report on. Sales orders, production orders, inventory, financial transactions. Start with these and learn the schema progressively.

Step 4: Build a semantic layer

Do not connect your report directly to raw ERP tables if you can avoid it. Build a set of simplified, pre-joined views or staging tables that reflect your business logic. This makes reports easier to build and easier to maintain when the source schema changes.
