You can use a current OBIS (Oracle Business Intelligence Server) metadata file with past versions of Oracle Business Intelligence.
As a result, you can open a repository (RPD), XUDML (Oracle BI Server XML API), or BAR (BI archive) file from an Oracle BI EE version such as 12.2.1.3, and modify the file with the 12.2.1.1 Administration Tool, biserverxmlexec, or other tools and utilities.
You can also use older OBIS metadata files with the current version of Oracle BI EE.
