BAM only tracks "long-lived" orchestrations (processes). By default, orchestrations are short-lived (with no DB signature). Make sure your process is long-lived. You set that property in Workbench (in the 'Processes' tab/view). Re-deploy afterwards.
First thank you for your reply
All my orchestrations (processes) are long-lived and I checked that my processes have the option BAM - auto dashboard generation.
so please if u have any idea/suggestion i'll be grateful.
