which join to use ? for records appearing 4 times in raw data in HANA

I am new to SAP and HANA so starting with small assignment. Records are appearing more than the no. of times they exist  in the Raw data section in HANA. How I can I solve it ? the join I took is Text join. But there is no SPRAS option. Following is the small assignment I am working on. I am trying to take PERNR from PA0000 table and link it to PA0002 table with other details to see.
