IF *No, then both deleted and non deleted records are copied. TRIGGER will not be copied using this command, We have to use ADDPFTRG to add trigger.
CRTDUPOBJ – Used to copy single obj or group of objects. We can duplicate data, constraints and triggers. When a logical file is copied into another library, two cases determine the basing for the file:
1. If both the logical file and its based-on physical file are originally in the same library, a duplicate of the physical file must be created in the new library before a duplicate of the logical file is created. After these two duplicates are created, the new logical file is based on the new physical file.
2. If the logical file and its based-on physical file are originally in different libraries, it is not necessary to duplicate the physical file before duplicating the logical file. Then the LF will be based on the original PF. Even if the pf is copied to new library, still the duplicated LF will be based on the original PF, not the duplicated PF.
