Error Message :
N/A
The DB change utility, ucybchng, creates an invalid entry for the attribute Shell in JOBS.UNIX.
Investigation
In the examples below, here are several JOBS.UNIX where the attribute 'Shell' is set to '-bash' or not set,. <Please see attached file for image>

All jobs are exported. With the 'DB change utility' all these entries should be changed to '-bash', regardless of what was there before. The following change script is used:
REPLACE_PART JOBS, *INC00124832*, UNIX_SHELL, '', '-bash'
Expected: Regardless of what was there before, all jobs will have '-bash' afterwards.
Actual: However, the results are that when there was something in the shell (not only -bash), it is deleted. Only if the attribute was empty before, will it have the correct value.
