 按业务月份读取发货数据，仓库固定为“常州简尚家居有限公司”。沿用配件补发扣款的包裹合并及条形码规则：按 `source_id` 合并运费，按明细顺序取第一个逗号前的条形码，删除最后一个 `-` 及其后缀。
 
-处理后的条形码匹配普通商品资料 `sku_id`，使用商品的 `supplier_name` 精确匹配供应商管理的 `scmname`，读取 `linkerprovience`（联系人省）。山东、山东省统一为山东；河北、河北省统一为河北。只有这两个省份扣除对应包裹全部运费，其他省份不扣，不套用快递扣款比例，也不要求匹配首发快递。
+处理后的条形码匹配普通商品资料 `sku_id`，使用商品的 `supplier_name` 精确匹配供应商管理的 `scmname`，读取 `linkerprovience`（联系人省）。山东、山东省统一为山东；河北、河北省统一为河北。只有这两个省份扣除对应包裹全部运费，快递名称1或快递名称2为“外采快递”时优先不扣款，保留已匹配的供应商资料，说明为“外采快递不扣配件运费”。其他省份不扣，不套用快递扣款比例，也不要求匹配首发快递。
 
 未匹配商品、商品未维护供应商、未匹配供应商档案、联系人省缺失、供应商或省份冲突、运费无效，均列为待核实，扣款额为零。同一条形码的多条商品记录若供应商相同，或同一供应商多份档案的省份经上述归一后一致，只计算一笔运费。零运费列为不扣款。金额按整数分汇总，页面和导出口径一致。
