Actual values in past fiancial periods not imported from one Primavera DB to another Primavera DB

Hello,

We try to migrate projects from one Primavera DB to another Primavera DB

Actual values are stored in Financial Periods

The period names equal in both DB (e.g.: 2023-08-01, 2023-09-01…) but the dates slightly differ

When we import the XML file, all the past actual values come into the columns "This Period Actual Units/Costs"

Are we missing something ? or is not possible?

Thanks

Sebastien
