You can set as many default values as needed. The <FieldDefaults> are set in the connection section of the system that you want to set values for.
<FieldDefaults>
<Field>
<Name>
F1</Name>
<Default>
V1</Default>
</Field>
[....]
</FieldDefaults>
For a default to work successfully, you must use a valid field value for the destination system.
Additionally, there are two ways for a <FieldDefault> to be recognized
- The F1 field is not mapped in the <FieldMapping> section
- If the F1 field is mapped in the <FieldMapping> section then the field in the source system MUST be null, otherwise the connector will use the mapping and ignore the default setting.
