Deleting Upgraded company in AX2012

Hi,

While deleting company from AX2012R2 CU7, showing attached error message. We want to know about 'How do delete particular company accounts with all transactions from that company?'.

Error message:

'Cannot delete a record in Ledger (ledger). The corresponding AOS validation failed.

We have upgraded companies data from AX2009 RU7 to AX2012R2 CU7.

Thanks in advance
