HANA Studio - Incomplete window function in rank node

I am creating a Calculation View and I need to use the Rank Node. I have used this same object in another project but in other environment and it worked well.

Now in my new client this Rank node always gives me an error "Incomplete window function in rank node"

I dont know how to solve this.

    Well, you defined "Top N" without specifying what N (=Threshold) should be.

    Try putting in something in the "Threshold" field and see if it works then.

    • This Threshold stuff allows you to choose what amount of recors to further in your model.

      E.g : you set threshold to 1 and rank node sorts data (desc) by WERKS, partitioned by EBELN and picks only 1 record for any EBELN presented in the data set.
