有时候，需要实现强制按照PR行来自动创建PO。
举个例子：假设2张PR，同一个物料，同一个需求日期等等的，在合并采购订单的时候，希望是2个PO行。
按照标准功能的处理逻辑，如果是同一个物料+需求日期（配置PO_NEED_BY_GROUPING=’Y’），在PR自动创建PO的时候，会自动合并为一行。然后发运行是2行。
如何实现？
实现的逻辑也不难，最近通过研究自动创建的包：PO_INTERFACE_S.create_documents
发现在PR自动创建PO的时候，如果po_requisition_lines_all.SUPPLIER_REF_NUMBER给的值不一样，则在自动创建的时候，PO会自动分组。这样子就可以比较简单地实现了让PO拆行的效果。
下面的代码注意这里：
AND ((pli.supplier_ref_number IS NULL AND l_supplier_ref_number IS NULL)
OR (pli.supplier_ref_number = l_supplier_ref_number))

SELECT MIN(pli.line_num) INTO x_po_line_num FROM po_lines_interface pli,po_requisition_lines_all prl,po_line_types_b PLT -- <SERVICES FPJ> WHERE pli.interface_header_id = x_interface_header_id AND pli.line_num IS NOT NULL AND prl.requisition_line_id <> x_requisition_line_id AND prl.requisition_line_id = pli.requisition_line_id AND pli.line_type_id = x_line_type_id -- <SERVICES FPJ START> Any new Service line types should -- cause the SELECT to fail (i.e. should not be matched). -- AND PLI.line_type_id = PLT.line_type_id AND PLT.order_type_lookup_code NOT IN ('RATE','FIXED PRICE') -- -- <SERVICES FPJ END> AND NVL(pli.ITEM_ID,-1) = NVL(x_item_id,-1) AND NVL(pli.ITEM_DESCRIPTION,'null') = NVL(x_item_description,'null') AND ((pli.ITEM_REVISION IS NULL AND x_item_revision IS NULL) OR pli.ITEM_REVISION = x_item_revision) AND pli.UNIT_OF_MEASURE = x_unit_meas_lookup_code --<INVCONV R12 START> -- replace x_preferred_grade to l_line_grade and -- removed secondary unit comparison.

当前，前提是这个栏位po_requisition_lines_all.SUPPLIER_REF_NUMBER您的系统没使用。
Trm上查询了这个栏位的作用：

就是：供应商的参考编号

而且在申请界面上也没发现维护这个值的栏位。所以猜测应该是一个参考的值的栏位。借用它来实现分组的效果应该问题不大。
大不了在新增之后，如果是属于客户化分组用的，再用触发器什么的将它清掉即可。
接着说一下具体如何实现：
1 首先，功能要考虑扩展性，所以，添加一个Profile的配置是必须的：
XYG_ALP_REQ_LINE_GROUPING
XYG-客户化应用
XXX:使用默认自动创建PO依据申请行分组
使用默认自动创建PO依据申请行分组
sql=”select lookup_code,meaning \”Grouping\”
into :profile_option_value,:visible_option_value
from fnd_lookups
where lookup_type = ‘YES_NO’”
Column=”\”Grouping\”(*)”

2 接着，在申请行添加一个触发器：

CREATE OR REPLACE TRIGGER XYG_ALP_REQ_LINES_TRG01 /****************************************************************************** NAME: XYG_ALP_REQ_LINES_TRG01 PURPOSE: 主要是利用supplier_ref_number栏位强制拆分采购订单行用 REVISIONS: Ver Date Author Description --------- ---------- --------------- ------------------------------------ 1.0 2017/03/08 Sam.T 1. Created this Trigger. ******************************************************************************/ BEFORE INSERT ON PO.po_requisition_lines_all REFERENCING NEW AS NEW OLD AS OLD FOR EACH ROW --- BEGIN IF NVL(fnd_profile.VALUE('XYG_ALP_REQ_LINE_GROUPING'),'N')='Y' THEN :NEW.supplier_ref_number:=CASE WHEN :NEW.supplier_ref_number IS NOT NULL THEN :NEW.supplier_ref_number||'->'||:NEW.REQUISITION_LINE_ID ELSE :NEW.REQUISITION_LINE_ID END;
   END IF;
END XYG_ALP_REQ_LINES_TRG01;

测试：
基本上就可以达到效果：

后台看数据：

—大功告成！
