Please post the <Name of the alias> definition here for all to see. Please also post the target of the alias.

Hi,
these are the MQSC definitions:
| Quote: |
DEFINE SUB('PoC') +
TOPICSTR('poc/#') +
PSPROP(RFH2) +
DEST('PoC.QA') +
WSCHEMA(TOPIC) +
REPLACE
DEFINE QALIAS('PoC.QA') +
TARGTYPE(TOPIC) +
TARGET('PoC') +
REPLACE
DEFINE TOPIC('PoC') +
TOPICSTR('pfx/poc/topic') +
REPLACE
|
And this is the result when I execute the commands:
| Quote: |
5724-H72 (C) Copyright IBM Corp. 1994, 2018.
Starting MQSC for queue manager QM1.
1 : DEFINE SUB('PoC') +
: TOPICSTR('poc/#') +
: PSPROP(RFH2) +
: DEST('PoC.QA') +
: WSCHEMA(TOPIC) +
: REPLACE
AMQ8470E: The object PoC.QA is not a valid subscription destination.
:
2 : DEFINE QALIAS('PoC.QA') +
: TARGTYPE(TOPIC) +
: TARGET('PoC') +
: REPLACE
AMQ8006I: IBM MQ queue created.
:
3 : DEFINE TOPIC('PoC') +
: TOPICSTR('pfx/poc/topic') +
: REPLACE
AMQ8690I: IBM MQ topic created.
3 MQSC commands read.
No commands have a syntax error.
One valid MQSC command could not be processed.

In Addition:
When I Change the TARGTYPE to QUEUE:
| Quote: |
DEFINE SUB('PoC') +
TOPICSTR('poc/#') +
PSPROP(RFH2) +
DEST('PoC.QA') +
WSCHEMA(TOPIC) +
REPLACE
DEFINE QALIAS('PoC.QA') +
TARGTYPE(QUEUE) +
TARGET('PoC') +
REPLACE
DEFINE TOPIC('PoC') +
TOPICSTR('pfx/poc/topic2') +
REPLACE
|

"looks different" is not a technical observation. It's akin to "it doesn't work."

Sorry, looks like you will need to have a program that republishes.
If you can determine where the message came from by looking at it on the queue, one subscription queue for all clients may be enough. You will have to consume the message and republish it to the new topic...

I meant:
- Defining a subscription to a topic alias does not work (error "... is not a valid subscription destination.").
- Defining a subscription to a queue alias does work.

I fear, you are right  .
Alternatively I have to convince my employer and the customers, to use a common prefix for all publications.
Thanks all for the help, ideas and arguments.
