SharePoint Designer: Get account details of the user who initiated the workflow using OOB Workflow Activities SPD Workflow: Get account details of the user who initiated the workflowBy default, SharePoint Designer (2007) doesn't allow you to retrieve the details of the user who started / initiated a workflow. The only option available using OOB workflow activities is to get the user who created the list item or to retrieve the user who last modified the list item, which in most cases will be the user who initiated the workflow, but not all.
to retrieve the account details of the user who triggered the workflow, you can create or modify a separate list item, then retrieve the account details of the item from either the Created By field or the Modified By field. As the workflow runs using the credentials of the user who initiated the workflow, when an item is created or modified by the workflow it will be done using the account of the workflow initiator.
