Allow Datapower to process element in the "usr" folder namely, "<XMSC_CLIENT_ID xsi:nil='true'>" in message coming from MQV9 client

IBM have examined the provided docs and was not able to extract the <usr> folder headers in readable format. They also checked that probe data and saw that the same input message is being parsed correctly when the headers are treated as MQRFH2. However, the same input message when being parsed as MQ Message properties (MQMP), the <usr> folder headers are missing. It seems that the one element in the "usr" folder namely, "<XMSC_CLIENT_ID xsi:nil='true'>" is causing this issue. They also tried to inject the same element in the "usr" folder using XSLT in DataPower service and it did not allow me to inject the same header in the MQRFH2 structure.

Based on our findings, the element with NULL value is getting truncated as part of the MQINQMP API call (https://www.ibm.com/docs/en/ibm-mq/9.1?topic=mqimpo-options-mqlong). This is working as designed. The proposed fix will only report the "MQRC_PROP_CONV_NOT_SUPPORTED" error in system log when the MQ Property has NULL value. If you want to process MQ message property with NULL value, you can open a request for enhancement (RFE) for DataPower. The product management will evaluate and will take decision on this RFE.

Regarding work around, you can process the MQ headers as MQRFH2 by using Parse Properties = off. Then you can convert the MQRFH2 headers to MQ properties using XSLT. W have provided some code snippet earlier on how to parse MQRFH2 headers. You will able to use that information to get the required headers and convert those to MQ properties. Please let us know if you have any other questions on this case. Thanks.
