To keep their prime keys consistent, key fields are automatically copied (based on name
matching) from a parent list element into new child elements (for example, those created
by using the scroll + button). If you want to inhibit this operation for certain fields,
define the TabMenu function dontCopyKeyNames_<LIST NAME>
to
return an array of fields that should not be copied into new elements of the list named
LIST_NAME
.
Example:
function dontCopyKeyNames_ENRL_FLD() {
return ['SEQ_NUM']
}
