Description
In certain branching scenarios, it is possible to edit the Exposure, Severity, and Controllability values and recalculate the ASIL, even if there are existing allocations on the FSR page or if the function has been decomposed.
Please find the scenarios:
There is a Safety Goal 1 with an FSR Child Allocation or Decomposition , other safety goal or ASIL doesnt have any allocations.
1) Under One operational situation, if there are 2 Safety Goal branches (Safety Goal 1 and Safety goal2)
I t's possible to update Exposure, Severity and Controllability values in HARA page and Exposure value in Operational Situation page.
2)Under One operational situation, if there are 2 Effect Branches ,
It's possible to update Exposure value in the HARA page and Operational Situation page.
3)Under One operational situation, if there are 2 Malfunction branches , It's not possible to update any values in the HARA page, but possible to update Exposure in the Operational Situation page .
