Hi Team -

When employee tries to send request to a participant added by manager, it displays the below message. The error text is incorrect & is not perceived positively by business. So we tried to make “Send Request” button greyed out for employee if participant added by manager via page personalisation, but could not succeed. We tried to use the below, but dint work. Would some one know whats the parameter to be used here?

#{pageFlowScope.pNotifyManager == 'false' and row.bindings.ParticipationStatusCode.inputValue == 'REQUEST_NOT_SENT' and row.bindings.LockedOutFlag.inputValue != 'Y' and pageFlowScope.pAllowSendRequest == 'Y' and pageFlowScope.pAllowTrackParticipants == WorkerId'}
