Example 4: Third-Party Payroll System Runs Retroactive Accounting (R2); Change Validation and Delimitation Functions are Active 
A third-party payroll system runs retroactive accounting. You only want the R/3 System to transfer the differences between the retroactive accounting payroll period and the comparison period to the third-party system during retroactive accounting periods.

For more information on the comparison period, see Defining the Comparison Period for Wage Type Options in Retroactive Accounting.
To do this, choose
retroactive accounting option R2.By activating change validation, you also ensure, as in example 2, that export wage types are only exported again if they have changed.

Make sure that change validation is only activated for the original periods, and not for the retroactive periods in payroll.
The change validation function for retroactive accounting periods is controlled by the R2 retroactive accounting option.
Change validation for the original periods in payroll also refers to the total value of the respective wage type and not to the differences.
To delimit wage types, follow the procedure recommended in example 2.

The system only delimits wage types if the respective wage type exists and has a difference in retroactive accounting.
The Total Gross Amount wage type has the following results data for the data export:
Payroll period |
Total Gross Amount wage type from the results table (RT) |

3 000.00 |
02 in 02 |
