Problems with window functions

[former_member541073]

Hey gurus.

Weve recently upgraded to HANA 122.17.

Ive got a problem with window functions in my graphical calculation view ( dimension type ) ( aka problems when using rank node )

I have created a calculation view where I use a rank node to get data that I need

Here is the rank node.

All fields are NVARCHAR typed.

On a prohection level everything works fine. I get the filtered data that i need.

Now, when I try to open data preview on the rank node I get the following message

I have this problem only with this rank node and my other rank nodes are working correctly ( at least I don’t get this error message )

Can anyone give some directions to how to resolve this issue ?

The problem has been solved using projection node with a table function, though the question with the rank node is still up.
