How to filter criteria in a chart based on a left selection of values from a specific dimension?

[Anonymous]

Hi,

I am really new to Qlik and i need to filter data in order to only process that portion on a single sheet

I can defend myself on Tableau but Qlik seems very different.

I have created a calculated dimension called "Dimension2" with the following formula:

if(match(left(details, 19),'DataRoam Unlimited:'), details)

Dimension2 = If match from char 1 to 19 of "details" dimension, show the dimension value match in that same row in "details"

I am expecting to only show as the dimension values with a match in a bar chart with the sum of a measure related to that dimension as long as it is matched based on the truncation rule of 19 characters.

With this formula I am still getting the entire list of values of the dimension so the filtering/matching i devised is not working at all.

Would you be able to share an image or a sample to show the issue?

if(left(details, 19)='DataRoam Unlimited:',details)

Coming at this from the left field per se, perhaps if you look at the data model and ascertain if dimensioning products as a dimension, by this I mean if "DataRoam Unlimited" is a product then would items such as this be better served in the loaded model rather than the calculated dimension ? This would be more performant especially if you have a large dataset.

Your post kept me thinking...

Filtering by a calculated dimension doesn't work, I am not fully sure why,

The solution was to create a calculated field in the Data Model viewer with the following formula:

if(left(details, 19)='DataRoam Unlimited:',details)

So combining Paul's and Jahanzeb's suggestions solved the problem.

Thank you!

However it doesn't work as a calculated dimension but rather a calculated field using the data model editor
