Error in Check In to PDM...

Hi all,
I am unable to check in a component into PDM. Originally it wascopied from Toolbox. No other special things are in this component.

The following error message appears when I try to check in to PDM.

"Check In of Toolbox and Library Documents is not allowed byadministrator!"

Thanks in Advance
