The conversion function creates a user profile that is used while the conversion function is running. This user profile has the name QP0FCWA. It is used by the conversion function to own converted directories in the file system if the original owner is unable to own their directories.
The user profile is deleted when the conversion has completed, if possible. Message CPIA08B is sent to the QFILESYS1 job log and the QSYSOPR message queue if ownership of a directory is given to this user profile.
