Where used for enhancement spot

Hi all,

I have found an enhancement spot CO_PROD_COSTING_CK and I would like to know if it is useful for my purpose.

I would like to put a break point in the standard code (just like I did in the past for normal customer function) in order to understand if the standard program call that enhancement but I wasn't able to find the point where it is called.

I am pretty new on enhancement spot so can you please explain me which procedure I have to follow in this case.

Thanks and regards

Alessandro
