Bro, do one thing, create 'Detail' objects for all the attributes in your gateway query. Some of them somehow won't be compatible objects on two queries. Therefore, create a variable, add the object, in the variable statement, just you can double click that particular object the one which you are creating a Detail one, change the data type to Detail and on the browse button point it to the gateway unique ID, which is the ID that you merged with your isoft query. Here you saying that the object is a detail of the Unique ID in both common objects in the query. That will create a detail object under variables. You should be able to add that object now in the table.

Hope that helps.
