Query with 3 joins not working

Query with 3 joins not working

Hi, I'm trying to build a query table by joining 2 tables with 150,000 records each. My data are such that I need at least 3 fields to match to get unique records. In fact it is four but because I encountered issue in saving, I used Concat function to combine two text fields but alas, I'm still not able to complete the query! FYI, of the 3 fields I'm trying to join the tables on, 2 are text fields (e.g.company name and currency) and 1 is date field (e.g. financial year end date).

I see the following error. Kindly help.

"Error Details:

Execution of the specified query was aborted, as processing time exceeded the allowed time limit. This is done to avoid any performance impact on the Zoho Reports service.

Some tips to avoid this:
Verify whether you have unnecessary table joins in the query Or could you simplify it further
Verify whether you have redundant "Order By" clause or any "Order By" over a general plain text column"
