Hi,

I have MRM TDS in Messages in my Flow and I want in error situation generate the exceptionList on the Message. My Idea is to paste the exception list on the RFH2 Header but what are the minimal ESQL instruction to generate the MQ RFH2 Header in a Comtupte node with the user tag ?

Thank for you help

PSN

You can try the following piece of logic for populating exception data to MQRFH2 user variables.

-- PARSING THE SYSTEM GENERATED EXCEPTION LIST TO FIND THE DEEPEST EXCEPTION
-- DECLARE VARIABLES FOR CAPTURING EXCEPTION DATA

DECLARE Path CHARACTER;
-- Current path within the exception list
DECLARE ErrorLocation CHARACTER;
-- Application where the error occurred
DECLARE ErrorProcess CHARACTER;
-- Action being performed within the application when the error occurred
DECLARE ErrorCode INTEGER
-- The error reference number
DECLARE ErrorMessage CHARACTER;
-- The Error Message
DECLARE ErrorDateTime DateTime;
-- Time when error occurred
DECLARE ErrorLogId INTEGER
-- MQSeries Message Id

-- START AT FIRST CHILD OF THE LIST

SET Path = 'InputExceptionList. *[1]';

-- POPULATE ERROR DETAILS AVAILABLE FROM EXCEPTION LIST

LOOP through all the children
Check if the error attribute is available
SET <error variable declared above> TO <respective error attribute in exception list>
Repeat the above two steps for all the relevant error attributes available in exception list

END LOOP

-- POPULATE ERROR DETAILS AVAILABLE FROM MQMD HEADER

SET <error variable declared above> TO <respective attribute in MQMD>
Repeat the above step for all the relevant error attributes available in MQMD

-- POPULATE ERROR DATETIME

SET ErrorDateTime variable TO <Current DateTime>

-- MODIFYING MQRFH2 HEADER PROPERTIES WITH ERROR VARIABLES

SET OutputRoot.MQRFH2.usr.<PROPERTY> TO <error variables SET earlier>
Repeat the above step for all the relevant properties
