How do I join two tables in SAP ABAP based on two columns?

Question

I have two tables ACDOCA and BKPF. The two columns are GJAHR and BUKRS. I want to join these two tables based on these two columns. What will be the code for the select statement?

I did this:

 FROM acdoca AS a
   LEFT OUTER JOIN bkpf AS b
     ON a~rbukrs = b~bukrs
     ON a~gjahr = b~gjahr

Upon activating, it is showing the error, " "ON" is invalid here (due to grammar). "

Please help.

Answer 1

The second "ON" has to be replaced by "AND":

FROM acdoca AS a 
     LEFT OUTER JOIN bkpf AS b 
     ON a~rbukrs = b~bukrs AND " => here
        a~gjahr = b~gjahr
