Displaying error message with context attribute values?

Hi,

I need to display the error message with the context value.

I am using the following method to display error message

CALL METHOD LO_MESSAGE_MANAGER->RAISE_T100_ERROR

        EXPORTING

          MSGID         = 'ZHR_MESSAGE' " Message Identification

          MSGNO         = '019'

          MSGTY         = 'E'" Message Type

          P1            = LV_WORKED_DATE.

Context value is not displaying along with error message.

Could you please help me tol solve this.

Thanks,

Sathish GS
