Qlik Sense not concatenating. Synth key with all fields.
I have loaded a table from a QVD file (which by now is empty) and then I have created another table in the script using preceding loads, with exactly the same field names as the one from the QVD.
I expected Qlik Sense to automatically concatenate both tables, but it has created a huge synth key with all the fields of both tables, so in the model view there are no "own" fields in any table and all fields in the synth key:
Like @Taoufiq_Zarra mentioned, use concatenate(). Sometimes it's handy to short-hand in a loop, letting it auto-concatenate, but it will make you and colleague's jobs harder to maintain/troubleshoot when you have to remember what tables are auto-concatenating when it's easy as concatenate(<tablename>)
