#Tableau tabular report update#
I was able to open the file and update the queries with no issues and no changes in Excel 2013.
#Tableau tabular report download#
Just download the file, change the values in the TabularInstanceName and TabularDBName queries, and refresh. You can download and use this model if you have Excel 2016 or 2013 with Power Query. The rest of the tabs use pivot tables and slicers. The Database Info tab uses cube functions to display the values shown.
#Tableau tabular report how to#
Ken Puls has a great explanation of how to get around this issue. “Formula.Firewall: Query ‘QueryName’ (step ‘StepName’) references other queries or steps and so may not directly access a data source. As I did that, I ran into a Power Query limitation as evidenced by the error message below. I built my model with the normal embedded connection strings and then converted them to use the connection Connection Info tables. In order to make this work for any model, I employed a trick I learned from Chris Webb to avoid duplicating connection information across queries. This enables me to merge data into a model that I feel makes the most sense and doesn’t suffer from too many relationships and hidden tables (which is what would happen if you just imported the results of each DMV query into the model).
My Power Pivot model uses Power Query to import the data from the DMVs. My example model was connected to a quick demo SSAS model I made based upon the Wide World Importers DW database.
You can download my documentation model here. Since I needed to document a tabular model for a client, I created a Power Pivot model in Excel 2016. This makes it necessary to store the data somewhere before transforming and merging them. Since DMVs require DMX queries, you are somewhat limited in your ability to join the data from the DMVs together. For more information analyzing your Power BI model, see Chris Webb’s post. You’ll just need to change the connection information to your Power BI instnce while the. I’ve been able to figure out the descriptions that correspond to some of the values, but I’m still missing a few.Īs with the MDSCHEMA DMVs, the TMSCHEMA DMVs can be used to document your model. There are a few fields that show IDs rather than descriptions (e.g., ExplicitDataType in TMSCHEMA_COLUMNS, Type in TMSCHEMA_DATA_SOURCES). While there are 36 TMSCHEMA DMVs, the main DMVs you will want to check out for model documentation purposes are: Until then I published a Gist that provides a list of those views as well as some notes on what kind of useful info is in each one.
I expect them to show up here at some point in the future. They are, unfortunately, not documented at this time (as of ). Not to worry, though. With the new compatibility level 1200 SSAS Tabular models came some new DMVs. For example, the MDSCHEMA_MEASUREGROUP_DIMENSIONS DMV seems to just return one row per table rather than a list of the relationships between tables. If you were used to documenting your SSAS model using the MDSchema rowsets, you might have noticed that some of them do not work with the new tabular models.
