Error description
When putting to a topic (or an alias that points to a topic) there are some differences in the way that MQPUT and MQPUT1 capture and record the class 3 accounting data which makes it hard to compare the values. In particular, MQPUT1 reports data against the wrong object. In some scenarios, MQPUT1 calls to a topic are recorded in the "other" API fields.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 3 Modification 0 and Release 4 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Class 3 accounting for an application * * which uses MQPUT1 with a topic target * * shows incorrect data values. * **************************************************************** When an MQPUT1 is made directly to a topic, the accounting record for the task does not include a WQ section for the topic. The data for the MQPUT1 call is added to the "Other" MQ calls section of the WTAS section. When an MQPUT1 is made to a QALIAS that points to a topic, a WQ section is created, but the object name contains the target queue for one of the subscribers.
Problem conclusion
MQ has been changed to identify the correct topic name when collecting accounting data for an MQPUT1 call and record data for the call in the relevant MQPUT1 fields in the WQ section.
