Problem with loading time of 1 column

[adrian33]

Hi, 

I want to use in my dashboard table with only 23 results, but that table takes sometimes more than 5 sec loading. What should i change in this dax code if I can enything. I thing that table like this should load immediately or faster than 5 sec 🙂

// DAX Query
DEFINE
  VAR __DS0FilterTable = 
    TREATAS({BLANK()}, 'rp OneTimeUseFlagDispositions'[OneTimeUseFlagDispoistionName])

  VAR __DS0FilterTable2 = 
    TREATAS({"GMC",
      "Lexus",
      "NISSAN",
      "Toyota",
      "FORD"}, 'rp Books'[OemName])

  VAR __DS0Core = 
    CALCULATETABLE(
      DISTINCT('rp OemIqSections'[OemIqSectionName]),
      KEEPFILTERS(__DS0FilterTable),
      KEEPFILTERS(__DS0FilterTable2)
    )

  VAR __DS0PrimaryWindowed = 
    TOPN(501, __DS0Core, 'rp OemIqSections'[OemIqSectionName], 1)

EVALUATE
  __DS0PrimaryWindowed

ORDER BY
  'rp OemIqSections'[OemIqSectionName]

Hi @adrian33 ,

Do you have a large amount of data? If there is more data involved in the query process, it will also lead to longer time, streamline the data as much as possible and delete the invalid ones.

Some learnings metrials worth recommending?

Understand star schema and the importance for Power BI … (bing.com)

The importance of star schemas in Power BI - SQLBI (bing.com)

On www.sqlbi.com you'll find everything related to DAX and models. Even optimization techniques.

This code does not look too complex. If it executes for a long time... it's time for you to work on the model, not the code. If your model is bad, no amount of DAX tweaking will make it better and the DAX faster.
