Passing multiple values as Input to RFC look up

Hello,

My requirement is to pass multiple values to the RFC and get one single output. I have declared my input as a table that has two fields and exporting parameter as a table type with only one field. RFC alone works fine but the look up in PI failed. It gives me null value.

I did refer toGraphical RFC Lookup and How you can design lookups for multiple values to be retrieved in a single call

and it did not work.

Appreciate your suggestions.

Thanks
