Posting not possible; new Asset Accounting is inconsistent

What causes this issue?

Your system is being switched to <LS>SAP Accounting powered by SAP HANA
</>. Only the new Asset Accounting is available to you there. You have
to migrate from the classic Asset Accounting to the new Asset Ac
counting, or complete the migration of Asset Accounting. Only then is it
possible for you to post in Asset Accounting again.
The following applies to the Customizing switch:
In the client, the Customizing switch for new Asset Accounting has the
status <ZK>In Preparation</>.
Or, in the client the Customizing switch for new Asset Accounting has
the status <ZK>Active (Posting Not Possible in Client)</>. It is <ZH>not
</> possible to post in accordance with the new logic in the local
system. The check displays an error during the import (for example,
inconsistent data).

System Response

As long as the Customizing switch <ZH>does not</> yet have the status
<ZK>Active</>, it is possible that the configuration could be
inconsistent. Therefore the system does not allow any postings.

How to fix this error?

First complete the Customizing settings for new Asset Accounting and
then activate the Customizing switch at client level (in Customizing for
<LS>Asset Accounting</> under Migration:<LS> </>Asset Accounting ->
<DS:SIMG.VV_T093BSN_PV02_DC>Activate New Asset Accounting</>.
If your data is consistent, posting is possible. If there are any
inconsistencies in data, you can analyze this in Customizing for <LS>
Asset Accounting</> under <LS>Migration: Asset Accounting -> Migration
for New Asset Accounting -></><DS:SIMG.FAA_CHECK_ACTIVATION_DC>Check
Prerequisites for Activating New Asset Accounting</>.
