Scenario: How can we see line item for a GL Account who line item display is not active?
Solution: The procedure would be to create an interim account, transfer the balances of your original account to this interim account, block the original account, activate line item display, Run a program called RFSEPA01, unblock the original account and get the balances populated again through a transfer from the interim account and then block the balance less interim account. If this had been done then you could view line items for your original account retro-actively also.
