We have this issue with Green Screens holding a lock on a record that a person is currently editing. Causes havoc with our other systems. If someone goes into update mode on a screen, then leaves their desk the record is locked the whole time.

Subject: Record Lock under Commitment Control
CAUTION: This email originated from outside of the ARRT. Do not click links or open attachments unless you recognize the sender and know the content is safe.
Hi,
I have a job running under Commitment Control with Lock Level of *CHG and Scope of *JOB.
Program A (RPGLE), which is in the call stack, opens a file with Commit, reads and updates a record in the file. Another Program B (RPGLE), which comes later in the call stack, also opens that file with Commit, but when it tries to read the same record, finds it locked.
I found this under IBMs Commit Lock Level documentation:
Within the same job, a program can change a record that has already been changed within the current transaction as long as the record is accessed again using the same commitment definition. When using the job-level commitment definition, the access to the changed record can be made from a program running within any activation group that is using the job-level commitment definition.
I am new to using commitment control. I understand that the record will be kept locked until the transaction is committed, but I was thinking that another program in the same job opening the file under Commit should be able to access it. Can someone please provide some insight into this.
TIA
