Qliksense SSE Error with two function calls on the same set of rows
I am new to Qliksense and I am trying to use Qliksense Server Side Extension (python) to call functions on Python Server side. However, I have an error to call two functions on the same set of rows.
For example, I have an ID column with value from 0 to 10.
I tried to call two functions F1 and F2 in the Python server: F1(ID) and F2(ID) and store the results in two columns, eg. Col1 and Col2
The problem is Qliksense sends the values of ID (from 0 to 10) to the first function and then empty value for the second function. It seems there is an error when Qliksense traverses the rows and the cursor comes to the end for the first function, and then can not reset back to the first row for the second function call.
What should I do to handle this? Do you have any insights? Thank you very much.
