Custom Message for AMDP bases Planning Functions not displayed in AO

Hi All

We are trying to display custom message in AO when we run Planning sequence. We have populated message in parameter E_MSG of the procedure MY_HANA_PROCEDURE.

E_MSG = SELECT 'RSPLS' AS MSGID, 'I' AS MSGTY, '000' AS MSGNO, 'PLANNING' AS MSGV1, ' SEQUENCE' AS MSGV2, ' EXECUTED' AS MSGV3, ' SUCCESSFULLY !!' AS MSGV4 FROM DUMMY;

The message is displayed when we run the Planning Sequence in RSPLAN. But the message is not coming when we run Planning Sequence in AO.

Please suggest.
