Your OLAP cube hides data from Excel but shares it with Power BI

If you're encountering issues with your OLAP cube not displaying all data in a Pivot Table while it appears correctly in Power BI, you're not alone.

This user's problem isn't a bug, it's a feature of how your organization has chosen to govern data. When an OLAP cube returns fewer rows to Excel than it does to Power BI, the cube isn't hiding data from you out of malice. It is enforcing a design decision that prioritizes performance and security for Excel users, while Power BI clients are given a different set of permissions or access paths. The discrepancy is real, and it is almost certainly solvable, but not by the user alone.

The practical reality is that OLAP cubes are built to serve multiple tools, and each tool negotiates the connection differently. Excel's pivot-table live connection often relies on older MDX queries and may be throttled by default member security or by a "drillthrough" limit that Power BI's newer DAX-based connection bypasses. Your IT team likely configured the cube to return a subset of data to Excel to prevent accidental overloads, while Power BI, designed for larger data volumes, gets the full scope. This is not a conspiracy against Excel users; it is a configuration gap.

What this means for you is that you have a path forward, but it requires a conversation with the OLAP manager. You are not powerless here. You can request that your Excel connection be granted the same role or measure-level permissions that Power BI uses. Frame it as a productivity ask: "I need the same data in Excel that I can already see in Power BI to complete my analysis." Most administrators can adjust this in a few minutes if they know it matters to you. If they cannot, ask for a Power BI report that exports the full dataset, or suggest they create a dedicated Excel-friendly view of the cube that matches Power BI's behavior.

The broader lesson is that modern data stacks reward those who speak up about access. The cube is not broken; the permissions are simply not aligned with your workflow. Instead of working around the gap, use the Power BI result as evidence to close it. Your data is already there, you just need the right key to unlock it in the tool you prefer.

Why your pivot table filters may be hiding more than you expect
Hi there, I am facing with a quite unique issue I think. There are some pivots in an Excel file that we use for internal reports for the AP team. The issue is that for the pivots there are several filters applied on, like Intercompany filter or "is the amount negative" etc. but there is the most important one is the Vendor filter, there are numerous vendors excluded, and I was like okay let me just recreate the pivot from the ground, but that would take a bit too much due to the vendor filter. The main problem is that the show details is not working, if I execute a double click on the pivot's total cells then it is loading for a 0.1 second and then nothing happens. If I try it after I close and reopen the file, then it loads for 2 seconds, with the botom right text saying "Reading Data" but then nothing, same results. It is a connection based pivot table, I tried to copy and paste into a new sheet the Pivot, didn't work, I tried to Save & Repair the file, it didn't work. Any idea? submitted by /u/Strange_Cell1142 [link] [comments]
Simplify your Power Pivot data updates without rebuilding from scratch
I'm trying to learn Power Pivot so I can use larger and different data sets using data models. For now, I only care about a single large data set (though I ultimately have others too) and a corresponding pivot table. The data set is in the data model as "load to" connection only and add to data model. I re-ran that data set updated and want to do what effectively I do with Excel datasets, just copy paste over the first and refresh the pivot table. I can't delete the original query and rename the new one and repoint because the pivot table automatically is cleared. I don't know if there's any other way to remove the original data set and overwrite with the new? I have one measure or calculated field in the data that I did recreate. I want to avoid recreating the pivot every time because that's inefficient. How do I approach this? submitted by /u/JayReddt [link] [comments]
Explore a smarter way to surface missing data in your sales analysis.
I have a list of 5 countries we sell products to. And we split it into 3 product categories: internet, consulting services, phone. I have used power query to and loaded the connection into the data model, but not as a table within a worksheet. These are my total sales amount pivot tables: Filter: USA phone | 500 mill Consulting | 20 mill Internet | 30 mill Filter: New Zealand Phone | 5 mill Internet | 20 mill Problem: I need New Zealand to show Consulting and a sales amount of 0. There is no “consulting” row in the source data itself for New Zealand so “show zero values” in pivot table settings doesn’t work I figure I’ll need to create my own tables listing: Phone, Consulting and Internet as row headings. But how should I get my sales sums? I’m guessing doing xlookups using my pivot table is the data source is not best practice Do I scrap my pivot tables and load the power query as a table for sumif? submitted by /u/Interesting-System [link] [comments]
