Optimise a Stored procedure in SQL? Facing Error - sql-server

Question

Can someone help me to optimise this SP as it takes more than 3 minutes to run and then it gives Timeout error. "Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding." I am a beginner and would like to optimise the below SP because it takes forever to give results and it also gives timeout error. I tried putting indexing to temp tables but unsuccessful. Help !!!!
