Member OOIORDDPZ file QDDSSRC in library *LIBL not found
This error is happening because when you are running the CRTLF command, it is looking for a source member that defines the LF. So, either you have not created it or wherever you put it it is not in your current *LIBL.
The source member will have all the specs for the LF: PF name. Fields if not selecting all or doing CONCAT, Select/Omit criteria if any, and Key information
