I am new to qlik and qlik community. I came across a requirement in which when selection is made in the hierarchical field the available values in the lower hierarchy had to be displayed in the text box . For example if there are two fields, viz, Brand and Parent-Brand hierarchy, When selection is made in Brand, text box should display all the distinct available fields in the Parent-Brand and vice versa.
One way I thought it could be done is using the Concat and Aggr function
=Concat(Distinct Aggr(Concat(Distinct Brand, ' '),Parent-Brand ), ' ' )
So if nothing is selected in the Parent-Brand, the above expression would display all the brands under the parent brand.
