Attachments activity. The Update Attachments activity will be added to the
orchestration. Double click the activity. The MS SharePoint Update Attachments

required changes.

Browse. The List Selection Dialogue is displayed with Lists of only supported
base templates which includes base template id as 100, 105 and 120. Select a List and Click
OK.

Schemas generated from that operation are displayed as nodes under the request input parameter in
the To Activity panel.

value can be provided by specifying a default value for element or by linking the element with an

for an optional input parameter, no exception is thrown during run time.
