When we import a workbook, the owner of the workbook and dataset is getting changed and showing who ever does export and import their name/id as the owner not the actual owner who created it, so is the Object ID. Due to change in Object ID, Classic BI reports which are developed based on the dataset are not working in the new environment.
Requirement is, Owner who has created DV Dataset and workbook from source OAC instance must be same in the target OAC instance where we import those. So while importing it is should preserve the Owner name same after import as well.
