Power BI and Business Central Integration for Posted Sales Invoice Drill-Through

Power BI and Business Central integration helps finance teams look beyond a posted invoice total. In Microsoft Dynamics 365 Business Central, a single sales invoice can create multiple general ledger entries behind the scenes, including Accounts Receivable, Revenue, GST or VAT, and discount postings.

With the right drill-through setup, users can click a posted sales invoice and instantly see every related G/L entry in one report, without switching tools or manually tracing transactions.

Posted sales invoices are accounting events, not just billing records. Finance users often need to answer practical questions such as which accounts were hit, how tax was posted, and why the invoice total differs from the revenue figure.

A Power BI drill-through report removes the need to jump between screens or search through Business Central manually. Instead, it links the posted sales invoice summary directly to the general ledger detail view, which makes reconciliation and audit work faster.

When invoice postings are visible in a clean ledger breakdown, finance teams can validate balances more confidently. That helps with audits, month-end reviews, and exception checking.

The attached solution is built around a simple but effective two-page report structure.

The first page acts as the main landing page for finance users. It should include:

The second page is the drill-through target. When a user right-clicks an invoice and selects Drill through → G/L Detail, Power BI opens the detailed view filtered to that invoice.

This page should show:

Power BI connects to Business Central through OData v4 API endpoints, which provide secure web-based access without additional middleware or custom drivers. The same integration pattern is also consistent with Microsoft’s Power BI and Business Central guidance, which supports using Business Central data with Power BI reporting.

Power Query can connect directly to the Business Central API v2.0 and pull in the required tables for invoice and general ledger analysis. This gives finance teams a practical way to report on operational data without leaving the Power BI environment.

A strong Power BI Business Central integration starts with the right data model. The report depends on connecting posted sales invoices to general ledger entries so the drill-through page only shows the ledger lines related to the selected invoice.

If the relationships are not designed properly, drill-through filtering becomes unreliable and the report loses value. A dedicated date dimension also improves performance and keeps the model easier to maintain.

The source document uses four Business Central tables to support the solution. This structure helps connect invoice headers, customer context, and G/L entry detail in a way that supports both summary and detailed analysis.

A single posted invoice can create multiple ledger entries. In the example from the attached document, a $50,000 sales invoice generates five separate G/L entries across four different accounts.

That kind of breakdown explains why the invoice total and accounting split do not always appear as a single line item. It also shows why finance teams benefit from a report that reveals the complete posting trail instead of only the invoice header.

A finance report only becomes useful if it stays current and responsive. The attached document includes several implementation practices that make the report more production-ready.

The report should be refreshed every 1 to 4 hours during business hours so finance teams always work with near-current data.

For larger G/L Entry tables, incremental refresh should be used where available, and the history should be limited to the last 2 to 3 years in Power Query to reduce load time and model size.

Import mode is recommended over DirectQuery for better visual performance, especially because G/L Entry tables can become large quickly. A “Last Refreshed” indicator should also be visible so users always know how current the data is.

Finance data must be protected carefully. The solution should use read-only access to the required Business Central endpoints and apply Row-Level Security so users only see the invoices and ledger entries relevant to their role or region.

A good finance report should not only be accurate; it should also be easy to navigate.

The source document recommends:

These small design choices make the Power BI drill-through report easier to use during audits, reviews, and daily finance checks.

This Power BI and Business Central integration gives finance teams a faster and clearer way to review posted sales invoices and the G/L entries behind them.

For inoday, it reflects a practical reporting solution that improves visibility, supports reconciliation, strengthens audit readiness, and helps finance teams make more confident decisions.
