Identical dep. terms not possible in chart of depreciation AC342

Dear all,

I was trying to do some testing and switched off the identical depreciation term flag from depr area 32 which copies from 01 in OABD. Now when I try to put it back on I get error message AC342. It pops up as an informational message, but SAP will not allow me to save by simply bypassing the message.

I've attempted to confirm that I've got all the same special depreciation settings for areas 01 and 32 by comparing to an unaffected environment. Clearly I am missing something.

Please let me know if you have any ideas.

Thanks
Jennifer

Identical dep. terms not possible in chart of depreciation US00

Message no. AC342

Diagnosis

Depreciation area 32 is defined to have the same depreciation terms as
depreciation area 01.
This is not (or no longer) possible since the two areas
treat the 'Special depreciation' depreciation type differently.

Procedure

If you want both areas to have the same depreciation terms, you have to
define the management of Special depreciation the same for both areas in
Customizing.
