Screen allocation : validation and submit button

Hi ProjeQtOr team,
My questions are about screen allocatio.
My configuration/context :
- projeQtOr release : 4.5.4
- Project PR linked with 2 Activity AC1 and AC2
- team project : 1 project manager (project configuration) called PM
1 activity responsable for 2 activities : AR. AR is différent of PM
3 resources/users : RS1, RS2, RS3

My questions :
- the users RS1 is logued and goes in work allocation screen.
Why RSI can see all team in resource drop list selection ?
For me, RS1 must see only himself, AR can see all team, PM see AR.

- for me the validation and submit buttons have an issue.
The RS1 can validate or submit anytime and can cancel.
I don't understand the workflow asociated.(I have read the manual)
Can you explain the behavior of the workflow ?

Thanks a lot.
Best regards.

Hi,
Thanks for your feedback.

I have created 3 new profils : DP, PM , DEV
I have a bad config in habilitation/specific_acces screen and validation_real_work section :
For DEV profil, I have filled "own elements" . I change with new value "no elements" and the behavior is godd now :
DEV member see only himself and can submit only, the validation of work is not possible .
It's OK now. Thanks

I have an other question :
In the project description there is a "manager" field.
In the activity (link with previous project) in treatment section there is "responsable" field
What is the difference between about the privilege of real work validation from dev team ?
Does the "manager" than validates the real work ? the "responsable" ? or both ?

Thanks a lot.
Regards
