The change of object owner is referring to the newly created user id.
Because you copy the user proflie, the authority given to that new user profile is that applicable to you by the QCRTAUT. Also the newly created profile will be owned by either your user profile (The creator) or your Group profile (the creator’s group profile.
So if your user id is QPGMRSMITH, and your Group profile is QPGMR, and the system value QCRTAUT has got *USE, and you create/copy a new profile NEWPRF, then NEWPRF will have PUBLIC authority of *USE (thanks to QCRTAUT) and will be owned by either QPGRSMITH (the creator) or QPGMR (The creator’s group profile) giving FULL access to its owner.
On the other hand, applications such as JDE, require to have full access to objects that it works with. Ownership of objects created by your new profile require to be fully accessable by JDE.
On the sample above, anything created by NEWPRF does not give proper access to JDE, therefore by changing the new owner to JDE, will give full access of the objects created by NEWPRF to JDE, thus allowing the application to function.
Private message me if you want.
