It's a Perl call to:
tag_data("__UI_META_TABLE__", "lookup_exclude", "orderline");
Or in ITL:
[data __UI_META_TABLE__ lookup_exclude orderline]
Basically as I can see from the code, it retrieves a value of
lookup_exclude field from the mv_metadata table, using "orderline"
That value is a number apparently, and the code uses is to discard
all entries from the orderline table which have order_number smaller
than that value.
Hope it clarifies,
