Clear values from a target instance
You can pass an empty value through a SOAP parameter to clear the respective value in the target instance.
You can also pass an empty (null) value through the &allow_empty_value=true SOAP query parameter to clear the respective value in the target instance.
For example, https://<instance name>.service-now.com/incident.do?SOAP&allow_empty_value=true lets you pass an empty value to the incident record in an instance.
You can then enter lines like the following in the SOAP request:
<assigned_to>value</assigned_to>
<assignment_group>value</assignment_group>
<category></category>
In the above example,
<assigned_to>value</assigned_to>changes the value in the Assigned to field to the value specified in the SOAP request.<assignment_group>value</assignment_group>changes the value in the Assignment group field to the value specified in the SOAP request.<category></category>clears the value in the Category field.
