CO-PC: inconsistencies in cost component structure OKTZ/TCKH3

Hi Gurus,

my customer needed to add a new Cost Component (AA) in the Cost component structure, in OKTZ.

When we launch ck11n, for new cost component AA the cost is OK, but in one of the other cost components (BB), there is a debit/credit of value calculated for the new ccomponent AA (of course, the cost component BB should be zero).

The problem is that in table TKCH3, in PRD, both cost components have the same value for EL_HV.

I read on some posts that it is necessary to delete the new cost component (AA) - directly in PRD - and then to re-create it.

Could this activity bring inconsistencies at database?

My customer already released cost calculation for this month, but he wants to fix the situation for next one.

Could you please help me?

Thank you and best regards

Sabrina
