when you call the function, have you passed the second argument? it seems you call the function as if it was a single argument one
e.g. if original funstion was 

fnTransorm(var1 as text)

and you called it as

fnTransorm(var1Value)

if the function would be 

fnTransorm(var1 as text, var2 as text)

but you still call it the old way

fnTransorm(var1Value)
fnTransorm(var1Value, var2Value)

HI @ouindia,

Can you please share some detail information of your queries table? According to error message, it seems like something wrong with your query steps.

Hi Xiaoxin

         I will try to explain each step how can i come up with that error

Background

        Our project is using SAP BW as backend and connect with PBI using import mode

Requirement

        We would like to change our prompt from single selection to multiple selection

Step to re-produce the error

In BW4HANA

      1. I created new variable with variable type as multi single value (the variable that we change is the currency type) in BW query

      2. Change the exsiting variable into new variable from step 1

      3. Save and activate

In PBI

       1. Try to refresh the report

       2. the error occur as below

Updated: last friday i changed my query from multi selection into fixed value (Meaning i just filter it with value instead of variable) after changing the error still occurred, However, we try to refresh again this morning and it's working fine now. The report can refresh it.

Thank you
