I think the alignment has been disturbed while you posted your code in this post.
What you can do is first load your first table CSKU as follows:-
KSTAR as KEY;
<Your select statement> ;
then load your second table GLPCP as follows:-
INNER JOIN (CSKU)
RACCT as KEY;
<Your select statement>;
This way you will get the required result.
Thanks & Best Regards,
