Data Manager wont Join two tables

[RichardLee]

I have two tables loaded into Qlik I am trying to join them together but

CONCATENATE LOAD

or 

Join in the Data Manager are not working.

is there anything I can try?

Hi, can you provide a data sample of tables or what error message you get when trying? Does your tables has common key field through which you are joining them? It's hard to understand what can cause this problem.

HI @RichardLee 

AS@justISO has mentioned we would need to at least see there fields in each table to be able to say exactly, also any error messages.

You would concatenate the tables when there data in the two tables are the same and you would Join where there are related.

@justISO I understand this but what I am saying is that I dont get any Errors or the option to join the two tables.

They are separate data pulls from two different databases. and when I select both of the Tables it still asks me to select a second.

I'm trying to understand your problem again. On Data manager window you added 2 tables from different sources. On the bottom middle you press '...' and select 'Concatenate or join'. You have 2 tables as circles here and if you select both of them, on bottom middle you still see 'Select a second table. The tables' fields will be mapped upon selection'?
Not as below, where I added 2 tables, first with 3 fields and second with 5:

I've restarted my machine and I now have the option to select Edit mappings so I don't know what it was.

The larger the tables with more rows and columns, the longer they may take to process, so I noticed too that Data manager can be laggy sometimes.

That's what I think my issue was.
