filter with column names as list of values and link with main table

[madhur4qlik]

I have a dataset with 700 columns which i need to put in a qliksense report with a custom report extension.

I need to categorize columns in different sets so those set name will be used as Filter object with those same category column names. for Example 

DATA:

Employee_Nm	Employee_Age	Employee_Desg	Employee_ID	Employee_Rgn	Company_ID	Company_Name	Company_Regn	Company_LOB	Company_age
John	35	MD	1234	NA	ABC	Happy Place	NA	HR	20
Peter	36	MD	1235	NA	ABC	OK PLACE	NA	IT	21

Filters required :

Employee	Client
Employee_Nm	Company_ID
Employee_Age	Company_Name
Employee_Desg	Company_Regn
Employee_ID	Company_Add
Employee_Rgn	Company_age

I can load the data,  i can club the columns with inline load but only problem i am facing how i can link the main data table with my inline load table.

i can use get field selection function but doing it for 700 columns doesnt make sense, So i am looking for some robust script logic which can help in linking my filter with my main table .
