A loop may exist in bill of material

 Hello All

I have added the parent item on the line , however when i click on the configurator button on the sales order i get this error message and configurator doesnt open up. pls let me know if any one is aware of this issue....,

"A loop may exist in the bill of material

Cause : This bill of material either contains a parent item referenced  as component or exceeds the maximum number of bill of material level.

Action : Disable a component referencing a parent item

Action : Increase the maximum number of bill of material level"

I am unsure of where do i try to get this corrected...
