Missing Group Ledger after SAP Upgrade - New General Ledger Accounting

Hi SAP Experts,

We are no sure whether post this incident on this forum, please advice

Some customizing points from New General Ledger Accounting have been lost during the "instance copy process" or "SAP upgrade process".

FROM:

TO:

After upgrade process we identify our Ledger Group 0L is missing on table V_FAGL_TLDGRP field LDGRP

I consider it is really strange after an upgrade a some customizing table data it just simply disappears.

IMG > Financial Accounting (New) Financial Accounting Global Settings (New) > Ledgers > Define Ledger Group

The Ledger Group "0L" is missing on this table (the standard one and main Ledger).

We are not sure whether to:

- Check whether exists documentation for "post-upgrade activities" related with "new general accounting"

     Maybe some "New General Ledger Accounting" adjustment must be done after a upgrade implementation

- Just simply customize the missing points and check what happens next with an integral test.

     Fortunately this happen on a "testing environment".

Do you know whether we could find this information?

Thanks in advance for your help and guidance
