Qlik Sense Interview Questions for Advanced

. How to design a cyclic group in the Qlik sense?

Ans: 

For solutions, we need to fix the basic settings mentioned below.

• Sample table structure: The branch state location of Id sample name
• Sample 1 branch 1 state 1 India
• Sample 2 branch 2 state 2 us

For designing cyclic drill, including

• State
• location

Creating and loading the information in order

Drill_below:

load * inline

[

SampleName, SampleName_Label

Branch, Branch Name

State, State Name

Location, Location Name
