Good Day Walter Xavier.
While searching for an answer, I came across the following information(taken from logging records):
sdticketid=chg:1521933,
sdticketid=cr:400868,
The field sdticketid is related to the value as shown on your 2nd screenshot.
You can also check this by executing the below queries against the mdb database (taken from a local example):
select * from usm_link_ticket_request_item where persid='chg:400001' or persid='cr:400001'
chg:400001 | 19 | 10398 | 10069
cr:400001 | 22 | 10016 | 10004
select * from call_req where persid='cr:400001'
400001 | cr:400001 | 22 | Disk broken | Disk broken
select * from chg where persid='chg:400001'
400001 | chg:400001 | 19 | Procure Server | SLCM Request Id 10069 Procure Server
Thanks and kind regards, Louis.
