problem in role 00000168

[Yifat Bar]

hello!
i am trying to use this role 00000168, in the standard workflow
WS30000015.
I keep on getting the following error : " activity 48: responsibility
'AC00000168'
is not valid agent for task TS30000016.
I also used it in my own workflow , and i keep on getting the same error.
what might be the problem?

regards
