[SOLVED] Resource affectation - by: apad

Hi

While trying to find a solution to my topic "9528-planning-calculation", I realize that I got a problem with resource affectation.
Have a look to affectation :

As you can see, there is a "hole" on the bottom of screenshot (between 01/08/2018 and 30/04/2019)
Almost all projects are cut in 2 parts (before 01/08/2018 and after 30/04/2019) except "P052_L001 - 1 - Lot unique" and "P047 - Bilans Normalisés - LOT 3 - Univers & Rapports BO"
I checked all start date and end date in each affectation, I see nothing wrong.
Can you explain me why I got this behaviour ?

Regards
