Changing Over an Account 
Prerequisites
In the Implementation Guide (IMG), define per bank area which currencies you plan to change over to Euro and set the indicator for release according to the principle of dual control. This indicator prevents an erroneous currency changeover. Releasing in accordance with the principle of dual control is optional, but SAP recommends you adopt this procedure.
It is not possible to undo an erroneous currency changeover of accounts.
Procedure
...
1. Go in change mode into the account you wish to change over.
2. Specify the account number of the account and the corresponding bank area.
3. Choose the section ‘currency changeover’.
4. Enter the request/order date and the changeover date.
Once you have maintained the changeover dates, the account has the changeover status (not the account status) ‘created’. Until released, the dates can be changed.
Alternatively, you can execute a mass changeover by choosing Periodic tasks ®Currency changeover ®Prepare currency changeover.You can make the selection of the affected accounts using bank area, account number, account holder, product and currency before changeover.
Release
...
1. Release the changeover data by choosing Account ®Release ® Release Currency Change.
2. Enter the required data and choose Execute.
Executing the release is subject to the authorization check. After execution, the accounts for processing appear in list form. In the first column of the list, a traffic-light shows the editing status of the accounts:
Red = release must be effected by another user
Yellow = release has been executed
Green = release is to be executed
3. Position your cursor on the relevant line.
4. Press the button ‘Release’.
Once released, the changeover data can no longer be changed. The status of the currency changeover stands at ‘Flagged for changeover (released)’.
5. On the specified changeover date, a program is automatically started that checks which changeover dates are before the next posting date and then changes over these accounts.
Deletion of the release
If you have erroneously released the changeover data and wish to undo this action, you must delete the release.
In the currency changeover section, a delete indicator also appears after release. Select the delete indicator field in the currency changeover section and then release the deletion, so that the release is removed from the account master data.
If the changeover data is flagged for deletion in the account master, (delete indicator is set), there is an error message in the log of the execute program (report) that checks the changeover data on the changeover date. The system does not perform currency changeover for these accounts.
Changeover without principle of dual control
Prerequisite for this is that you have not set the principle of dual control indicator in the Implementation Guide (IMG).
...
1. Go in change mode into the account you wish to change over.
2. Specify the account number and the corresponding bank area.
3. Choose the section ‘currency changeover’.
4. Enter the request/order date and the changeover date.
Once you have maintained the changeover dates, the account has the changeover status ‘flagged for changeover’ (released). You can still change the dates until the execute program changes over the account.
Result
The selected account has been changed over from one of the participating currencies to Euro.
By flagging an account for Euro changeover, a block indicator is automatically set on the account. As long as the account is not changed over to Euro, all postings with a posting date after or on the changeover date are held back. These items are noted in a separate table and updated later. No updating of the general ledger takes place. Prerequisite for the floating of items is that the amount can be determined in account currency after the currency changeover. If this is not the case, the item is rejected showing the indicator ‘import error’.
