BizTalk 2010 Map destination message show all nodes - biztalk

Question

I have a source schema with less elements than the destination schema. When I run the map only mapped elements in destination schema shows up. I want all the elements in destination schema to show up, even they are empty. How to do this?

Answer 1

Set the "Default Value" of the output schema. This will create empty nodes.

Answer 2

The most convenient way is to use Inline C# Scripting functoid for this.
Scripting functoid:
public string GetEmptyString()
{
return System.String.Empty;
}
You can just link this functoid to all output nodes where you wish to see empty node.
Example:
Input schema:
<xs:schema xmlns="http://person" targetNamespace="http://person" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Person">
<xs:complexType>
<xs:sequence>
<xs:element name="Name" type="xs:string" />
<xs:element name="Surname" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Output schema:
<xs:schema xmlns="http://employee"
targetNamespace="http://employee"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Employee">
<xs:complexType>
<xs:sequence>
<xs:element name="FirstName" type="xs:string" />
<xs:element name="MidName" type="xs:string" />
<xs:element name="LastName" type="xs:string" />
<xs:element name="Age" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Input message:
<ns0:Person xmlns:ns0="http://person">
<Name>John</Name>
<Surname>Snow</Surname>
</ns0:Person>
Expected output message:
<ns0:Employee xmlns:ns0="http://employee">
<FirstName>John</FirstName>
<MidName />
<LastName>Snow</LastName>
<Age />
</ns0:Employee>
Solution:
Link Person.Name to Employee.FirstName
Link Person.Surname to Employee.LastName
Create Scripting functoid that returns empty string
Link Scripting functoid to Employee.MidName
Link Scripting functoid to Employee.Age
