Direct Cover Status from Parent and Child Requirements

Hi all,

i have the problem that status of the parent requirements is not depended from the status of the child requirements.

The parent Requirements shows nothing or Not covered, even if i select the the checkbox Full Coverage in the Tab "Test Coverage".

The child Requirements are shown their correct status Information in the Direct Cover Status filed, but this will not inherited to the parent requirements.

I read in some boards, that i need to write a script in Workflow. Unfortunately I am new in HP ALM and hope somebody can support me.

Thanks in advance!
