LSO - How to create classroom training records in the past using LSO trans

Hello,

we are managing classroom training outside SAP but we want to maintain retrospectively the information in LSO in order for employees to see in the Portal as Completed Training.

When using the LSO transaction (e.g. LSO_PV08) to book the participant the system uses the current date. And this date is not modifiable using PP01 for the system does not allow direct maintenance of "E A025 to P" relationship.

Is there a way to "control" the booking date?

Thanks

Kind regards,

Olivier
