    Question Excel Dashboard "First Click Is Slow" problem

    Hello Excellers,

    this is my first post ever in an Excel forum at the ripe old age of 56.

    I just did an introduction post if you want to know who I am.

    Anyway, some colleagues and I have developed what we think is a better way of building Excel Dashboards on Excel O365.

    My colleagues have put out a post about it here:

    www dot meta5 dot com/2020/04/26/meta5-enabling-the-excel-data-mart-dashboard/

    On that post you can download a detailed white paper on how the dashboard is built and you can also download the dashboard itself.

    My question here is this.

    We are using the O365 internal data model and power query inside Excel to be able to support multiple slicers across all the charts and reports in the dashboard.

    When the Excel workbook is opened up it now opens up quickly as we are not "pre-loading data on open".

    But on first click of a slicer it appears that Excel is loading the data in to the power query model some how an then applying the click.

    So we have the "first click is slow' problem.

    I am guessing there is a way to fix this with some option for the workbook but I have no idea what that might be.

    As I said, you can download the actual workbook (it's bigger than 1MB) from the link.

    It is a public workbook with randomly generated data in it.

    If you want to learn how the dashboards were created there is a detailed white paper.

    My colleagues are planning on building LOTS of these dashboards so you might want to learn about what we are doing.

    But this "first click is slow" problem has been something of a nuisance as we work out how to do dashboards in the best possible way in Excel.

    Any comments would be most welcome!

    Best Regards

    Peter Andrew Nolan

    "Ripe old age of 56"? What a positive attitude you have! I will be 56 next month and I have only just entered middle age.

    Welcome to the forum.

    There are instructions at the top of the page explaining how to attach your sample (i.e. trimmed down) workbook.

    By the way, please don't expect anyone to download and read a white paper in order to help you - that won't happen, and you should not expect it, nor should you expect members to follow external links to find your workbook.

    Re: Excel Dashboard "First Click Is Slow" problem

    Hi Ali,
    well, for my part, I am actually quite surprised to be above ground so 56 is a ripe old age for me. 99% of men who ever lived did not reach this age. :-)

    Sure, I can trim down the data in the workbook and load it here. I was more thinking that since it is a very obvious problem that someone would know the answer off the top of their head without having to download it.

    It can't be that it is "normal and acceptable" that the first click on a dashboard to resolve queries in to the power designer model is slow. There is nothing special about the dashboard. And the second and later clicks are subsecond.

    But I will cut it down and put it in the post.

    Also, the white paper is for the education of Excelers. We have created a better way to build excel dashboards than using SSAS as the source. Anyone who wants to have a look is welcome.

    We are using a product that was one of the first BI products that can now send data directly in to the power query model.

    By doing this we are going to make it possible to use Excel far more cheaply to build BI style reports and dashboards.

    By "cheaply" I mean significantly reduced development time for dashboards and reports over what is possible when using SSAS.

    Ok?

    And sure, most people will not read it. Only people who want to be more effective in building Excel dashboards will read it.

    Best Regards

    Peter

    If it were a "very obvious problem", you would not need to be here for help, but as you are, might I suggest that you do as you have been asked?
