Because this Web Service takes two inputs, the Edit Input Columns dialog appears. For now I am not binding the input columns to a parameter, simply because we do not have any parameters at this point in time. Go ahead and hit OK:
By now, the Universal Creation Wizard has finished its task by creating all basic objects that a universe needs. In our case, the web service has two mandatory inputs, so we need to take care about those in order to get some data back from the web service.
I have a list of world currencies in a CSV file, so I am creating two parameters in the Data Foundation that will get their List Of Values from the CSV file:
Go to the data foundation and right-click on the table, hit Edit Input Columns:
And map the newly created parameters in the Data Foundation with the Web Service input parameters:
After mapping the parameters you are good to go!
