Simple script that can be used to set an assessment or survey back to in progress. Run this script in a background script or fix script. Alternatively, you can also create a UI action.
var asmt = new GlideRecord("asmt_assessment_instance");
asmt.get('sys_id_of_assessment_instance');
asmt.state="wip";
asmt.setWorkflow(false);
asmt.autoSysFields(false);
asmt.update();
