I need a help on a data load in Qlik Sense Desktop.
I have two data tables which I need to connect by two values Transaction type and Document ID so that I might analyse data in a Qlic Sense. there is no other way bacause only these two vales identyfing records between those tables.
Strictly speaking you can just load the two tables you described above and Qlik Sense will take care of creating a 'synthetic key' to join the tables correctly. Often users will manually create a composite key to eliminate the synthetic key as described by Saumya and Manish in order to keep the data model clean and efficient.
