Mapping for multiple columns

[New-Qlik]

Hello,

I have a table with millions of data and i have created 4 mapping tables based on that one table. It takes so much time to refresh application as every time those 4 mapping load runs for millions of data. 

Thinking loud but is there any other smart way to do mapping with  multiple columns in one go.

TIA

Could you explain with an example?

Hi Avneet,

There are multiple possibilities.

1. Do you really need a mapping? Otherwise, use a (left) join
2. Create a mapping with concatenated fields and use SubField for the correct applymap execution
