Replicate zcostelement hierarchy datasource from Prd to QA

Hi All,

I have a costelement hierarchy which was manually created in BW PRD system and I want to replicate the datasource associated with this hierarchy in BW QAS . As the hierarchy is too long and complex, I want to avoid the manual upload of hierarchy thru flat file

I need all the steps required to replicate only the datasource that is attached to zcostelement hierarchy and not all datasources from BWPRD.

Once I have the datasource , I hope all I need to do is create the Infopackage and schedule the load.

Please give me all the steps.

Thanks in advance
