Hi,

I am sending a message to SAP system using WBIA SAP adapter and composing the MQRFH2 header as follows:

SET OutputRoot.MQMD.Format =MQFMT_RF_HEADER_2;
SET OutputRoot.MQRFH2.(MQRFH2.Field)Version = 2;
SET OutputRoot.MQRFH2.(MQRFH2.Field)Format = MQFMT_STRING;
SET OutputRoot.MQRFH2.(MQRFH2.Field)Encoding = InputRoot.MQMD.Encoding;
SET OutputRoot.MQRFH2.(MQRFH2.Field)CodedCharSetId = InputRoot.MQMD.CodedCharSetId;
SET OutputRoot.MQRFH2.(MQRFH2.Field)Flags = 0;
SET OutputRoot.MQRFH2.mcd.Msd = 'xml';
SET OutputRoot.MQRFH2.jms = '';


The output received in windows platform differs from Linux platform.

Output from Windows Platform is as follows:

<mcd><Msd>xml</Msd></mcd> <jms/>

Output from Linux Platform is as follows:
<mcd><Msd>xml</Msd><Set/><Type/><Fmt/></mcd> <psc><Topic/></psc><jms/>

The empty tags in Linux is causing the message to fail in WBIA adapter for SAP. The exception message is as follows:

javax.jms.MessageFormatException: MQJMS1050: The MQRFH2 header has an incorrect format.

If I manually post the message from windows then the SAP adapter is parsing the message successfully.

I tried setting the values of Set Type and Fmt to null but it did not work.

I am using WBIMB 6.0 CSD 03 in both windows as well as linux.

Any ideas?

Hi,

The problem is resolved as of now. []

Let me explain more -

Basically we were using PROPAGATE to generate multiple idocs from a single input XML. The CopyMessageHeaders() function within the while loop was causing this kind of behaviour.

This problem can be resolved in two ways:

1. After the call to CopyMessageHeaders() we need to nullify the Properties tree values as follows:

SET OutputRoot.Properties.MessageSet = NULL;
SET OutputRoot.Properties.MessageType = NULL;
SET OutputRoot.Properties.MessageFormat = NULL;

2. Use CopyMessageHeaders() outside the while loop and compensate using PROPAGATE DELETE NONE. This is more strange way of doing it.

I would prefer to use the first method as PROPAGATE DELETE NONE would eat up more memory.

Thanks to all of you for your kind support.

There's already a PMR open about the "strange" behaviour of CopyMessageHeaders() under some circumstances. I know, because I opened one when it bit me.

Cheers.
