(Livestream Replay) Making a Real Report Fully Bilingual: Harder Than you Thought! - with Bernat Agulló

DESCRIPTION 📄

Translating a model metadata does almost nothing in the direction of translating a real report. Translating the data is necessary, and you need to be able to translate titles and display names, even those coming from field parameters. Different strategies are needed to translate the different bits of the model and bring it back to the report so that with a single click everything changes the language. It's a lot of work.

GUEST BIO (Bernat Agulló)👤

Bernat is an enthusiast Power BI developer from Barcelona, part-owner of Esbrina and Data Platform MVP since 2022. He blogs mostly about calculation groups and Tabular Editor C# Scripting, but also about challenges he has found as a consultant. One of his latest challenges has been making a Japanese-only report turn into an English-Japanese report. Other recent highlights include modifying the report layer with a c# script or integrating Visual Studio and VS code with Tabular Editor to leverage GitHub Copilot to author C# Scripts.

(Livestream Replay) Building Income Statements in Power BI - with Chris Barber

DESCRIPTION 📄

Profitability is a key metric for any business, as profits can be distributed back to shareholders either directly or indirectly. An income statement—also known as a Profit and Loss (P&L) statement—answers high-level questions such as “What was our net profit last year?” while summarizing key revenue (e.g., product revenue) and expense (e.g., R&D) items.

Unlike static reports, a P&L semantic model provides granular detail, enabling users to explore insights such as “How was R&D spending distributed across projects, fiscal periods, or legal entities?” With a well-structured model, users can analyze financials dynamically through Power BI reports, PivotTables, and Excel formulas.

GUEST BIO 👤

Chris Barber is a Chartered Accountant (ACMA, CGMA), four-time Microsoft MVP, and author of Income Statement Semantic Models. He runs StarSchema.co.uk and has created popular YouTube videos (100K+ views) and courses (1K+ participants) focused on building Profit and Loss (P&L) reports in Power BI.
