I don't see what your common date has to do with hotel names. Those aren't dates. You need to get the dates from the different tables into the link table and replace them in those tables with a date key. Perhaps this document helps: Linking to two or more dates
The document link you shared links all the dates in tables using OrderID I guess. The four tables in my data doesn't have such a unique ID common to all tables. Any suggestions how to link them?
I'm sorry, I'm new to Qlik Sense hence don't know much about data modelling. I'd really appreciate any help.
