Hi,
Please go through below reply:-
1) Yes, you can use the ledger group which is having Ledger B and C to have same posting in both the ledgers. You are getting error ‘Data cannot be posted to the combination Ledger..’ because of missing configuration at configuration node ‘Define and Activate Non-Leading Ledgers’. You can get that clue from the message ‘GU167’.Please find below screen shot for the same:
2) For “Depreciation posting" from a specific Depreciation Area, you can use the Target Group at configuration of ‘Define How Depreciation Areas Post to General Ledger’. Specify the ledger group which only contain ledger ‘B’ or ledger ‘C’. Please find below screen shot for the same:
3) Historic data:
If posting is done without assignment of the ledger (refer point #1) than you need to contact SAP for migrating historical data. SAP will provide their consulting service which is chargeable for migration of historical data only to non-leading ledger.
Risk of such subsequent changes is also highlighted in the SAP note # 891144 - FI-GL (new)/document splitting: Risks of subsequent changes.
