Oracle排序函數Rank
出口給報關行出貨的時候，同一票shipment中合併多個invoice跟packing，轉出到廠商的報關系統時候，出口報關的序號會將invoice的序號做自動增加。
因為wafer會有出口給其他外包做初階加工，加工完之後再回貨，回貨就是需要再進口回來。進口做報關的時候就會有原出口的報單號碼，也需要明確到報單的項次。
因為原本出口并沒有字段記錄對於的出口報關項次，所以只能重新去計算一遍。
舉例如下，SI# 100600486為兩筆invoice並單出貨，第一筆INV#100614-03-CSS有30個項次，第二筆INV#100615-01-CSS有11個項次。

這裡其實主要是用到RANK函數，依據INV NO跟SEQ NO來做排序得到一個排序之後的序號，結果如下：
