OTL Timecard LOV Sort Order

Question

Hello,
We have an LOV field on our OTL timecard called Rate Up. It is a custom timecard created by someone who is long gone. We would like it sorted in a particular order. We identified a database view that is likely the source of the data, but adding an ORDER BY in the view did not work.
This is probably really simple when one knows how. How can we put a sort order on this LOV?
Thank you,

Both of these suggestions are really close. I thank Avinash and Giuseppe for their advice.
I found a validation set named XXEP_OTL_RATEUP_CODE_TK, but it is already sorted. We use this validation set on the Oracle Forms style OTL Timekeeper screens, but not on the web self service screens, where our sort problem exists.
I enabled diagnostics without any useful information, but a trace gave me the following sql statement which uses hxc_cui_custom4_v. I added an order by into the view, cleared cache, logged off and on, tried a different PC with a different user, but no luck sorting. So where is this select specified, so I can add an order by?
Thank you,
