Deleted Group Counter

Hi

we have 2 group counter, 1 for pc and 1 for set. apperantly the one for pc is deleted/removed.

Is there any way to get this back?

Seemes that it is out there since I get this message when try to create a new.

"The inspection plan identifier exists already. Enter another" I was hoping that I could recover or something like that since we have around 100 000 material numbers in this inspection plan.

Thanks
