Inbound Mapping: The source panel will show the text area where the user can modify the template we provide as SoapUI does. We support CSV, XML, and Json formats. The user can enter the data into the template and execute the mapping test. The mapping result is shown in a table tree view on the left panel. We don't need to show the mapping result in a text area as CSV, XML, or Json. The mapping result shows the result in a table view, and there is no need to make any changes. The mapping result contains the final data with the sObject field names ready to be posted. But we are not doing the real posting. We show only the mapping result for debugging purposes and analysis.
Outbound Mapping: The source side shows the sObject and the mapping result in a table tree view is displayed on the target side. We provide the query editor to let the user choose a sObject record where we read the data and provide for the mapping test. Then the user doesn't need to enter the complete data. He can modify the data we have read from the record if needed.
