How can I custom a attribute or metric in Date format?

Hi Lena, 

if you're creating insights via Analytical Designer - all the insights already display the date in the following format: MM/DD/YYYY. More details can found in the below documentation: 
https://help.gooddata.com/doc/en/dashboards-and-insights/analytical-designer/visualize-your-data/create-insights

Alternatively, if you're creating reports via the Report Editor as outlined in the below documentation: 
https://help.gooddata.com/doc/en/dashboards-and-insights/reports/working-with-reports/creating-new-reports-in-the-report-editor
 

You have 2 options to change the display labels: in the report and you have two choices:

1) In table mode, right-click on the date header and select a new "display label" from the menu

2) Otherwise, under "HOW" dialog box in your report, select your date dimension, and in the third column, select the most appropriate "display label". 

Hope this helps! 

Hi Lena, 

my apologies for not initially understanding the issue here - please correct me if I am wrong, the issue here is that your metric returns a number, not the date in this format: mm/dd/yyyy. You can use a custom number formating to change the display in the numeric expression. Please see the following documentation that will help you with this:
https://help.gooddata.com/doc/en/dashboards-and-insights/maql-analytical-query-language/maql-use-cases-and-tutorials/finding-min-and-max-dates-using-date-arithmetic

In the above documentation, we have the following example - you'll need to slightly tweak this for your usecase of: mm/dd/yyyy

SELECT MAX ((SELECT (10000 * MAX(Year (Date))) + (100 * MAX(Month (Date))) + (MAX(Day of Month (Date))) BY <connection point>)) WHERE (SELECT COUNT(Date (Date), <connection point>) BY Year (Date), ALL OTHER) > 0

Hi Michael,

I had the issue which can not use multiple Date dimensions in one Insight, I found that this issue was fixed today, please following this link: Cannot pull multiple Date dimensions into one Insight | The GoodData Community

Currently, there is still another issue, I cannot use this formula: Status DIQ: select THIS - “WO Closed Date”,   because the “WO Closed Date” haven’t included in the Insight.

Example for another formula I can use: Tickets DIQ: select THIS - “Ticket Created Date”, this formula is usable because “Ticket Created Date” column is already included.

Could you please take a look on this? 

Thanks!

Hello,

Based upon a recent feedback from a customer, I would like to highlight the workaround that can be used for displaying the year.

As described in: https://help.gooddata.com/doc/enterprise/en/dashboards-and-insights/manage-custom-date-dimensions

Comparing to the urn:gooddata:date date dimension, the urn:custom_v2:date date dimension uses a different method of calculating date aggregations.

For example, a metric returning the latest year (such as SELECT MAX(Year)) would return the ID of the attribute value corresponding to the year, not the actual year (for instance, 121 instead of 2020).

With the workaround:

If you need to display the actual year, update the metric:

Subtract a numeric value that equals the ID of the attribute value for the year. To do so, select the corresponding year from Attribute Values in the right-hand side menu. For information about editing a metric in the Custom Metric Editor, see Get Started with Using MAQL to Write Metrics.

Add a numeric value that equals the year. For example, for the year of 2020, the updated metric would look like the following:

SELECT MAX(Year (Date)) - 2020 + 2020

In other words, if your data template is urn:custom_v2:date, the following will not work for displaying the year:

SELECT MAX(Year (Date))

The following will work:

SELECT MAX(Year (Date)) - 2020 + 2020

The number marked in bold needs to be selected from the list of attribute values, not typed manually. The other option would be to convert the date template back to urn:gooddata:date.
