performance management

Hi,

We have a requirement to make DFF field mandatory in 'Share and Release' performance task, so that manager should not share the PD until he will update the DFF field value. But manager is able to share and release the PD without entering the value in DFF. Please suggest how we can make the field required with Performance task flow.

We have used below EL#

Show Component: #{(pageFlowScope.pDocumentInfoMap['pPerformanceDocumentStatus'] == 'COMP' ) or (pageFlowScope.pDocumentInfoMap['pPerformanceDocumentStatus'] != 'COMP' and pageFlowScope.pDocumentInfoMap['pPerformanceTaskCode'] == 'SHRPDOC' and pageFlowScope.pDocumentInfoMap['pPerformanceRoleCode'] == 'MANAGER')or (pageFlowScope.pDocumentInfoMap['pPerformanceDocumentStatus'] != 'COMP' and pageFlowScope.pDocumentInfoMap['pPerformanceTaskCode'] == 'FF' and pageFlowScope.pDocumentInfoMap['pPerformanceRoleCode'] == 'WORKER')}
