A couple of things based on the Explain output provided:
1)An EXPLTYPE = (CURRENT) is requested in the Explain control cards. This should read the rows in the PLAN_TABLE, etc. except this is being overwritten to be EXPLTYPE = (FUTURE) . There is a message in the output indicating this.
2)Since a FUTURE explain is being done, statements are passed to the DB2 optimizer as dynamic statements (instead of static) so I believe this why the access path can now show as AQRYTB. If you wish to verify this, you could change PLANTAB = (ROLLBACK) to PLANTAB = (COMMIT) and then browse the PLAN_TABLE after the explain completes and I expect you will find the rows inserted by the PPA Explain show an 'A' in the ACCESSTYPE column. This value is determined by DB2.
3)The reason the EXPLYTYPE is overridden is due to AUTO HVersion @FUTRDBA being used as specified in the DATABASE = (AUTO,@FUTRDBA,TDB2) control card. The parms from the HVersion @FUTRDBA override some control cards. To see the options associated with this HVersion, use option AH from the PPA main menu and use B to browse @FUTRDBA.
