Determination of Comparison Period Using First Method if New change validation Attribute Is Flagged 
Prerequisites
The Toolbox uses this variant if you
It is assumed that the third-party system has received the data from the retroactive accounting periods as well as from the original periods.
Use
We recommend that you use this variant because the disadvantages of the
old variant do not apply. The Toolbox now uses the new variant as the standard for a new interface format.Advantages

For the first export after a change that covers several payroll periods, the changes are sent for each payroll period affected by the change.
In retroactive accounting for payroll, the preceding payroll periods are defined using the rule that the last original period is always used as the comparison period.
Rule
The system always determines the most recent payroll period in which the
for-period view matches the payroll period. If this does not exist, the last exported payroll period is used. The payroll period can be a previous retroactive period for the current export if it exists or the last payroll period of the past export.These rules are described in an example.

The payroll periods listed in the table are applicable for an employee.
