Generated DSO can not be deleted

Hi Experts,

Because of the lack of the information related to the generated DSO for UOM, we've tried to convert the DSO to HANA Based DSO.

We've got an error message :

"Optimized for SAP HANA' property is not permitted (UOM_IOBJNM)
Inconsistencies found while checking DataStore object UOMIOBJNM
Function module /A1S/CCA_AFTER_REPORT_ACTIVAT does not exist"

I've tried to delete the DSO but now it's giving another error message :

"Could not set lock: Object already locked by UOMIOBJNM MIGRATE_IPRO."

Can you please help me to solve this issue ?

Thanks a lot,

Z
