objects are already locked by another change SAP HANA SP9

Hi,

When I tried to Import a package in DU to Hana Qual server, I have this message  :

" Repository: objects are already locked by another change;Repository::import(): some of the imported objects are already locked due to  following changes_entries: {changeID: (srcSystem: , changeNumber: 167, container: ), objectID: {tenant: , package: ATA_PACK_TEST_DU, name: ATA_AV_TEST, suffix: analyticview}}, "

How can I unlocked these objects and why they are locked ?

Any idea ?
