In Workday, effective dated transactions and non-effective dated transactions refer to how data changes are managed and recorded in the system.

Effective Dated Transactions are changes that are recorded with a specific effective date. This means the change will be reflected in the system only when that date is reached. For example, if an employee's compensation is changed on November 13, 2024, with an effective date of December 31, 2024, the new compensation change will be reflected in Workday only from December 31, 2024.

From a PECI perspective, PECI will extract the employee with the above changes only when the effective dates fall within the pay period the integration runs for. Assuming that you are running integration with the current period and your pay group has a monthly schedule, these changes will appear in the PECI extract the first time the integration runs in December. In this case, the Entry Moment will be November 13 and the Effective Moment will be December 31.

Non-Effective Dated Transactions are changes that do not have a specific effective date. This means the change is considered effective immediately and remains in effect until another change is made. For example, if an employee's personal information is updated, this change will be effective immediately in Workday as soon as the business process is completed.

From a PECI perspective, PECI picks up non-effective dated transactions in the next integration run. In this case, both the entry moment and the effective moment will have the same value. (Assuming you are running the integration for the current period)

I hope it helps.

Thanks
