I am facing very strange issue.
I have created one simple calculation view and created one join with tables VBAK and VBAP and joined both of these
with key VBELN.In JOIN node when I am doing data preview for both of these tables separately its showing output but when i click on join node and click data preview ' Its showing blank table' and same when i converted join to union or projection I am getting the same result.
Can someone please help? Am I doing something silly ?
