[SOLVED] Message "l'activité parente doit appartenir au même projet"

I cannot reproduce such issue.
In fact the message tells you that you cannot have an activity under another activity (that will be its parent activity) if both activities are not on the same projects.
But this may never happen during copy.

On which version on projeqtor are you ?
Could you please try and reproduce on demo so that we can investigate on existing use case ?

Hi,

As you subscribed to our support and hosting services, you could have pointed out the issue through our tracking instance.
We would have better reactivity

I recorded the ticket on your project to follow up.

I will not access your data (we will never do this unless your direcly request for it).
I uploaded a plugin on your instance that will realize an anonymous dump of your db.
Please "install" it (it will generate an anonymized dump and uninstall itself) and post result on the ticket (#3281)

Please also indicate id of the project you try and copy (we won't have the name on the anonymized dump)

Hi,

I succeded to retreive anonymized batargetkup and test.
On your template project #4, the milestone #12 is inconsistent : it has a parent activity, but WBS position does not reflect this position.
Just reset the field "Parent activity" on milestone #12, and then you'll be able to copy the project.

NB : source of this issue is fixed on V6.5.6.
I can migrate your instance on V6.5.7 on your request.
