Auto-Concatenation of Dimension Rows or Columns The default setting is Tableau is that when more than six (6) fields are placed in Columns/Rows, you notice that the first two fields are grouped, separated by a comma. Sometimes this is annoying and unwanted. To resolve this issues: 1. Open Tableau Desktop. 2 .Select  Analysis  >  Table Layout  >  Advanced  > Adjust the number of Rows or Columns (Default 6) as desired. Note:  The maximum value is 16. It can be changed by saving the Tableau workbook as XML and updating the value and save it back to Tableau Workbook. Go to Tableau video link below on how to do it:  https://www.youtube.com/watch?v=2DJIaKto5pE&feature=youtu.be

How View URLs Are Structured The parameter names and values are case-sensitive. The operators and date & time function names are case-insensitive. Characters like comma (,) and ampersand (&) in value should be prefixed and suffixed with tilde (~) symbol to differentiate itself from syntax elements.For example, CompanyName=Syncfusion Inc~,~ Invalid parameter name will get ignored from filter consideration. Invalid parameter value will result in “No data available to display” in widgets.   S tructure of the base URL In Tableau Server or Tableau Online, the basic URL pattern for a Tableau view is: http://<servername>/#/views/<workbook>/<sheet> In a multi-site environment, for views saved to sites other than Default, the site ID is also included in the URL: http://<servername>/#/site/<sitename>/views/<workbook>/<sheet> Adding parameters to the base URL To create a filtering URL, you append a  query string  to the base U

AntiVirus programs may have different options to do this unique to the program, such as using wildcards in the path (*), or an explicit option to add child folders. To help make sure these exclusions are set for full coverage and take effect: Include the above paths and programs in exclusions for all scan settings,

Tableau limit filters by number and type Filtering in Tableau is extremely powerful and expressive. However, inefficient and excessive filters are one of the most common causes of poorly performing workbooks and dashboards. Note: Showing the filter dialog requires Tableau to load its members and may create extra queries, especially if the filtered dimension is not in the view. Reduce the number of filters in use . Excessive filters on a view will create a more complex query, which takes longer to return results. Double-check your filters and remove any that aren’t necessary. Use an include filter . Exclude filters load the entire domain of a dimension, while include filters do not. An include filter runs much faster than an exclude filter, especially for dimensions with many members. Use a continuous date filter . Continuous date filters (relative and range-of-date filters) can take advantage of the indexing properties in your database and are faster than discrete date filters
