Trying to use a standard MDM web service

Hi,

I am trying to use a standard MDM web service in SUP environment, having many many fields as input parameter.

Now, in this input parameter we need to only pass the customer and destinationName as input and skip the rest of the fields.

When i am trying to use this web service in SUP 2.1.2 and then try to preview it, it results me with NULL values and a warning.

Preview

Result

So, is there any way i can skip/delete the other the NULL value fields, so i can get the expected result.

if any one have idea of how to doing this , please share ..

Thanks a lot ...
