After 2018 Q2 release, when you go to Employee Profile, under background elements, you found for some attachments the 'Last Updated' date is changed to a date post April (for example 04/11/2018) unexpectedly.
Similarly, when you go to Admin Center>Manage Documents, the last updated date for those attachments are also changed.
SuccessFactors Employee Profile v12
This is an expected behavior for attachments uploaded before 2018 Q2 release. In Q2 we have implemented a job called DMSGDPRInfoMigration for GDPR needs. The job history can be found in Provisioning>Monitor Jobs>Select the specific job type 'DMS GDPR information migration job'.
DMSGDPRInfoMigrationJob will do migration for legacy attachments hence the "Last Updated" date was changed to the date when job was run.
Note: "Last Updated" date field only applies to EP v12. Since 2018 Q4 release, all instances will be migrated to PP3 version globally, hence no "Last Updated" date will show in People Profile anymore.
