Hello Expert,
I am new SAP PLM module, so I am unable to figure out why I am getting below error message while clicking on specific project task.

I am able to open other task and can see deltailed screen.
I found an alternate solution, where I can add my User id at Parent level and system allows me to see the task details but not sure if that is a right way to do.
I am stuck and not able to find why I am able to see other task details and not for this perticular task
Could you please guide me how can I find a solution for this error.
Thanks,
NJ
