We are facing one of our client requirements for legacy data migration which is not only for account balance or open items, however they need to migrate all transactional details in accounting journal level including financial activities of fixed asset items.

The concept of data migration in SAP standard data migration workbench using template seems to be based on migrating either GL account balance, Open items(AP/AR/GL) and Fixed asset balances.

Please advise if there are any SAP functions or workaround solutions available for making this kind of business requirement?
