Invoke Form - Output Instance XML

This property is used to get the data from the Forms which you have edited from the Work items page. Depending on the type of XML variable selected in this property, the XML data is stored, provided the output instance XML has the same schema of the Form.

For instance:

1. If the Output Instance XML is of type XML List , then the XML data received from the Form is stored in the respective List depending on the list item scope defined for the XML Variable.

   1. The list item scope should be New , if a new list item has to be added with the Form data in list.

   2. The list item scope should be Current, if the list item that initiated the workflow has to be updated.

   3. The list item scope should be List Query, if a specific list item has to be updated in the list.

2. If the Output Instance XML is of type XML Document, then the XML data received is stored in the workflow itself.

Scenario: Display an existing list item data using Invoke Form and then store the updated Form data in a different list (destination list): An intermediate XML Variable is required for such scenarios. Use an Update Variable activity before the Invoke Form activity, to assign the Source list XML values to the Intermediate XML Variable, Then use this intermediate XML variable as Input Instance XML and destination XML List as Output Instance XML.
