CHANGE_CASE in RMSSUB_XDIFFGRP
Why does RMSSUB_XDIFFGRP have a change_case function which changes the case to upper for diff_group_id? Why is non-upper case not allowed for this field?
...
IO_message.diff_group_id := UPPER(IO_message.diff_group_id);
...
Converted Data which is not entered through UI can be non-upper case.
