ASKB - Periodic Asset Postings

Hello dear all,

When i launch the transaction ASKB in test modefor month 10, i obtain the following error:

- Account 'Revaluation of acquisition and production costs of assets' could not be found for area 88 - for company CC01.

Enter this account in account determination for assets -

The problem is that the system never ask me about this account in the previous months, and we never customize it since the beginning of activities.

Why the system ask me about it today ?

I need your help.

Thanks
