I work with Power Query & Power Pivot. I load several tables in the data model of Power Pivot thanks to Power Query. Then I create relationships between those entities.
Now that the tables are linked with each others, is it possible to benefit from it and dump the whole data in a sheet? I must allow the users to see the whole thing in a table, not just summaries with pivot tables.

I have a ton of records across 5 different tables in Access that I'm consolidating in one query.
I want to now be able to connect that query to excel and pivot the data that is in the query. Is that possible? If so, is there a way to do it without added VBA? I was thinking of slowly exporting the consolidated data into a new table in access but with over 7 million records, it'll take some time. Anyway to save myself that headache? When I connect the DB to excel, the only tables that are coming up are the 5 tables and not the query.
Moderator please move to appropriate forum if required.
I use MS Excel 2016 for data visualization.
Can understand Extract means saving Excel data onto a spreadsheet and Transforming data means manipulating it in Power Query.
QUESTION:
But if I decide to load data to Power Pivot (Data Model) doesn't that fall back into Transform because you can
Create Calendar Table
Create Measures (or Calculate Columns if necessary)
Or does using Power Pivot (Data Model) fall under Data Modelling because you are no longer formatting, merging pre-existing data;
Rather you are creating new data (i.e. Calendar Table, Measures, etc) to merge with pre-existing data
Kindly clarify
Power Query (now standard excel 2016 in data tab): is an ETL (Extract - Transform - Load) tool. A standard example would be that you would connect it to your source ERP system, and make a product table. That wouldn't be an exact copy of the table, but could consist out of several tables, that are joined. You keep only the relevant columns.
Power Pivot: this is a data modelling tool, it allows you to create relations between data and attribute tables. It gives you the possibility to use time related measures (YTD, Previous Year, ...).
In general when you build your model in power pivot, you can choose to either load the data directly into power pivot (without power query). This is useful if you already have a datawarehouse in which the ETL process is done.
If you have an ETL process to execute, it's better to use power query, and load the data into power pivot. (option: load to data model).
I created a multi dimensional pivot table in Excel and then used the following add on to generate the MDX: http://olappivottableextend.codeplex.com/releases/view/618637
The MDX was generated by Excel as follows:
SELECT NON EMPTY Hierarchize(DrilldownMember({{{DrilldownLevel({[Customer].[Customer Geography].[All]},,,INCLUDE_CALC_MEMBERS)}}}, {[Customer].[Customer Geography].[State Province].&[New South Wales]&[Australia]},,,INCLUDE_CALC_MEMBERS)) DIMENSION PROPERTIES PARENT_UNIQUE_NAME,HIERARCHY_UNIQUE_NAME,[Customer].[Customer Geography].[State Province].[Country-Region],[Customer].[Customer Geography].[City].[State Province] ON COLUMNS , NON EMPTY Hierarchize({DrilldownLevel({[Customer].[FullName].[All]},,,INCLUDE_CALC_MEMBERS)}) DIMENSION PROPERTIES PARENT_UNIQUE_NAME,HIERARCHY_UNIQUE_NAME ON ROWS FROM [Adventure Works DW2012] WHERE ([Measures].[Sales Amount]) CELL PROPERTIES VALUE, FORMAT_STRING, LANGUAGE, BACK_COLOR, FORE_COLOR, FONT_FLAGS
I then opened the Power Pivot windows and copied and pasted the MDX. It generated a two dimensional data structure.
I realise that Power Pivot is available because of the max row limitation in Excel i.e. it can deal with more rows. Is Power Pivot just a two dimensional data source? i.e. it is used to get all of the data into one place so that a standard Pivot Table can be used to analyse the data from a multi dimensional perspective?
It is the pivot table which is using mdx. Pivot tables came about around the same time as olap - they use the same technology. I think even if we create a pivot and point it at a server-side tabular model then the xl pivot will still be talking in mdx.
So the pivot table needs to work with mdx irrespective of the data source.
Power Pivot and Tabular models use a language called DAX. Tabular uses analysis services but is different from multi-dimensional .... it is tabular
I have used Power Pivot to create some calculated fields from a table of data.
Then I use the modified table, with the calculated fields to create some pivot charts back on the excel workbook.
In the same way I linked the original dataset (excel table) to Power Pivot, I would like to link the table in powerpivot with the calculated fields back to excel. Is this possible?
yoshiserry, the best way to share PowerPivot stuff is PowerView (Excel 2013). If you want to share just the table, regular Excel file should be fine -- people even without PowerPivot installed will be able to work with it (with some limitations).
I'm looking for a way to load more recent data as date x in Power Pivot and link/add them to an existing table.
Background:
The user downloads data from a datafeed and saves them in Excel Power Pivot.
The data will be deleted from the server afterwards.
In the next step, new data must be added to the existing table in Power Pivot,
so that the workbook graphics can access the complete dataset.
I know there is no API for VBA access to Power Pivot. Is there a
workaround with linked tables and direct access to the database?
1) you create one table just containing the dates from earliest to far into the future
2) you import every new set of data into a new power pivot table
3) you link the dates for a record in the newly imported table to the dates in the power pivot table containing the dates
so the backbone of your whole data is the dates table, while your tables keeping the actual data are treated as lookup tables.
this is hacky and I didn't try it, but it should work
