But are you sure your ticket is linked ot a version ?
Didi you try option "avec version en service" (by default report displays items linked to versions not deployed yet) ?

If problem persists, check for errors in the log file.

below screen shot of the list or tickets concerned by this project

The version is correctly put.
and there isn't error in the log file.

Could you confirm that if is the target version is empty in search field, all tickets should be listed ?

Thank you

Could you confirm that if is the target version is empty in search field, all tickets should be listed ?

What do you mean by "search field ?

NB : the project you selected on the Report parameters is not the project the ticket belongs to...
Maybe this is the source of the project.

I confirm that the ticket belongs to the project selected.
However, to obtain a result i must put a version in the parameters

Concerning "search field", i talked about "parameter" used for filtering request in the report screen.

Hi,

When project is selected, this report lists all versions linked to this project.
So maybe the expected version is just not linked to the project.
If you remove the project, you'll see the tickets.

OK thank you for your advice. Now it's OK for this point.
However, there is a problem because when i select a main project with several sub-projects. I don't see the tickets of sub-projects

When you select project, you won't see tickets of sub-project, nor tickets of the project.
This report deals with versions.
You'll see tickets linked to the versions linked to the selected project.
I must admit that current report does not include versions linked to sub-projects of selected project : this will be an improvement in next version.
