Mass adoption

You can adopt the standard rates that you specified on the Standard Currency Rate Maintenance page for the target historical rates.

In the mass adoption process, the rate for *_OB schedule details is calculated in this way:

If the year of the base period differs from the year of the current period, the rate type is by default set to Do not adopt. The average rate selection is disabled and, instead of Do not adopt, you can select only F - Closing Rate. The period type is set to Base period and the current period selection is disabled.
The base period's closing balance is required to match the current period's opening balance. The base period's closing balance rate is automatically applied to the current period's opening balance rate.
If the year of the base period is the same as the year of the current period, the rate type is by default set to Do not adopt. Instead of Do not adopt, you can select F - Closing Rate or A - Average Rate. The period type is set to Current period but you can select Base period instead. For the rate calculation for other schedule details than *_OB schedule details, this logic is used:
```
Rate = (Local Currency value in the Current Period) ÷ (Group Currency value in the Base Period + (Difference between Local Currency values of Current and Base Periods ÷ Rate to adopt or selected Rate Type))
```

Note: By default, the All Schedule Details option is enabled and all schedule details that are available in Business Modeling are displayed. If you disable the All Schedule Details option, only schedule details that are relevant to HS and HD rate types and the Mass Adopt dialog box's selected context are displayed.

Mass adoption calculations require the target period to be in the Open status. The base period can be in any status.

The entity currency must be configured on the Entity Parameter page for the base and current periods. Otherwise, an error is displayed.

Verification of the currency consistency is performed and, if inconsistencies occur, these errors or warnings are displayed:

For a currency mismatch for a single entity or all entities:

Different Entity Currencies in the Base and Target periods. Enter the rates manually in the Historical Currency Rate Maintenance screen.

For multiple entities with partial validity:

Some entities have different Entity currencies for Base Period: <value> and Target Period: <value>. Entity <value> - Base Period Currency: <value> - Target Period Currency: <value>. Enter the rates manually in the Historical Currency Rate Maintenance screen. Continue anyway?

If no schedule is assigned to an account with the HS or HD currency method, an error is displayed, including a list of accounts with missing schedule configuration.

To run the mass adoption process, perform these steps:

Specify the context data for the historical rates on the Historical Currency Rate Maintenance page and click Mass Adopt.
Specify the version, entity, base period, and target period for the mass adoption.
By default, this information is already specified, except for the base period, and contains the values that you specified in the Context panel. The base period always refers to the last period (period 12) or month of the previous year. The target period is automatically populated with the period selected in the context of the Historical Currency Rate Maintenance page.
In the table, select one rate type and period type for each schedule. The rate type indicates the standard rate that is applicable within the specified context and selected period type.
These rate types are available:
- Do not adopt: Default option. No adoption applies to the corresponding schedule detail.
- F - Closing Rate
- A - Average Rate
The period type specifies which period is used to retrieve the selected rate type.

These period types are available:
- Current period: Default option. The current period corresponds to the target period that is selected in the context of the Mass Adopt dialog box.
- Base period: The base period corresponds to the base period that is selected in the context of the Mass Adopt dialog box. By default, the base period is period 12 (defined in Business Modeling) of the previous year.
Click Save and close.

The mass adoption process is run. H and HI rates are determined by the context selection and the current period's closing rate. HS and HD rates are determined by the context selection and the selected rate and period types per schedule detail.

You can see the results of the mass adoption in relevant reports, such as entity reports in a group currency.

The mass adoption setting applies to all accounts for which historical rates are configured.
