Informazioni su questo servizio
Are your Power BI Grand Totals showing incorrect numbers or blanks? Does your calculation work on a row level but fail completely at the total row? Is your DAX code running slow or throwing evaluation context errors?
Incorrect context transitions and broken relationships can break the integrity of your business reporting. I analyze and fix DAX logic issues directly at the engine level.
What I Can Fix & Build For You:
- Grand Total Evaluation Fixes: Correcting row vs filter context mismatches using SUMX and iterating functions.
- Time-Intelligence Calculations: Accurate Year-over-Year (YoY), Month-to-Date (MTD), and Year-to-Date (YTD) measures with custom date tables.
- DAX Performance Optimization: Refactoring inefficient formulas with VAR (Variables) to speed up slow visuals.
- Data Model Audit: Fixing inactive relationships, circular dependencies, and incorrect filter propagation.
- Complex Custom Measures: Dynamic conditional metrics, ranking (RANKX), and target achievement rates.
How We Work:
- You share your .pbix file (or an anonymized sample) along with the expected result.
- I identify the logic breakdown, optimize the DAX measure, and verify totals across all matrix levels.

FAQ
Do I need to share my company's confidential or private data?
No. You can share an anonymized version of your .pbix file with dummy numbers or scrambled text, as long as the data structure, column types, and table relationships remain identical.
What if my calculation requires a custom Date table for YoY or YTD?
I will generate a fully dynamic Calendar/Date table using DAX, establish the correct active relationships, and mark it as a Date Table to ensure all Time-Intelligence functions execute properly.
Can you optimize slow-loading dashboards and visuals?
Yes. Inefficient calculations and circular dependencies significantly slow down visuals. I refactor complex code using variables (VAR) to minimize engine query scans and speed up visual rendering.
What happens if the formula breaks when new data is added?
All formulas are designed to handle dynamic row iteration and edge cases (such as division by zero or blank fields). If an issue arises related to the agreed logic, revisions are included to resolve it.
