Change to mainframe batch job AMHRPX5 to produce the notifications for PPRS Lien holders

This change is from an OPS issue #3752 Notice of change of location not printed.

The batch job AMHRPX5 producing the notifications for PPRS Lien holders when there is a new Transport Permit Document types (103) is not working. The batch job uses the DOCUREGI number as part of the MHR Document search and stores the last DOCUREGI processed. Once modernization started doing Transport Permits the DOCUREGI number value exceeded all legacy application DOCUREGI values (because we have separate ranges between legacy and modernization). The batch job is now using a modernization DOCUREGI value since March 15. This means any Transport Permits issued through the legacy application which have PPRS lien will not be picked up by the program.

John McColl will get started making the changes, which will be very similar to those implemented in AMHRPX1 which executes separate searches for legacy and modernization rows in the Document table.

BA testing and verification will be required.

Start by comparing batch jobs AMHRPX5 and AMHRPX1, especially how AMHRPX1 searches separate legacy and modernization rows in the Document table. Confirm the DOCUREGI handling and the required behavior for legacy Transport Permits with PPRS liens, then complete BA testing and verification.
