请购单的类型只有两种，一种类型是Internal Requisition，，用于内部组织间的物料申请；另外一种类型是Purchase Requisition，用于产生PO，对外部供应商的采购申请。
Tables
采购申请主要涉及以下三张表PO_REQUISITION_HEADERS_ALL,PO_REQUISITION_LINES_ALL,PO_REQ_DISTRIBUTIONS_ALL.
header表和lines表通过REQUISITION_HEADER_ID关联，header lines
lines表和distributions表通过REQUISITION_LINE_ID相互关联，lines distributions
PO_REQUISITION_HEADERS_ALL
PO_REQUISITION_HEADERS_ALL stores information about requisition headers. You need one row for each requisition header you create. Each row contains the requisition number, preparer, status, and description.
.
REQUISITION_HEADER_ID is the unique system-generated requisition number. REQUISITION_HEADER_ID is invisible to the user. SEGMENT1 is the number you use to identify the requisition
in forms and reports. Oracle Purchasing generates SEGMENT1 using the PO_UNIQUE_IDENTIFIER_CONTROL table if you choose to let Oracle Purchasing generate requisition numbers for you.
.
PO_REQUISITION_HEADERS_ALL is one of three tables storing requisition information. PO_REQUISITION_HEADERS_ALL corresponds to the Header region of the Requisitions window.
.
SEGMENT1 provides unique values for each row in the table in addition to REQUISITION_HEADER_ID.
PO_REQUISITION_LINES
PO_REQUISITION_LINES stores information about requisition lines.You need one row for each requisition line you create. Each row contains the line number, item number, item category, item description, need-by date, deliver-to location, item quantities, units, prices, requestor, notes, and suggested supplier information for the requisition line.
.
LINE_LOCATION_ID identifies the purchase order shipment line on which you placed the requisition. LINE_LOCATION_ID is null if you have not placed the requisition line on a purchase order.
BLANKET_PO_HEADER_ID and BLANKET_PO_LINE_NUM store the suggested blanket purchase agreement or catalog quotation line information for the requisition line.
PARENT_REQ_LINE_ID contains the REQUISITION_LINE_ID from the original requisition line if you exploded or multisourced this requisition line.
.
PO_REQUISITION_LINES is one of three tables storing requisition information. This table corresponds to the Lines region of the Requisitions window
PO_REQ_DISTRIBUTIONS_ALL
PO_REQ_DISTRIBUTIONS_ALL stores information about the accounting distributions associated with each requisition line. Each requisition line must have at least one accounting distribution.
You need one row for each requisition distribution you create. Each row includes the Accounting Flexfield ID and requisition line quantity.
.
PO_REQ_DISTRIBUTIONS_ALL is one of three tables storing your requisition information. This table corresponds to the requisition Distributions window, accessible through the Requisitions window
Distribution里的三个Account信息所对应的PO_REQ_DISTRIBUTIONS_ALL表里的字段
Debit(DR):CODE_COMBINATION_ID,
Credit(CR):ACCRUAL_ACCOUNT_ID,
Variance:VARIANCE_ACCOUNT_ID
这三个Account信息都可以在GL_CODE_COMBINATIONS_KFV中查找到。
Queries
SELECT * FROM PO_REQUISITION_HEADERS_ALL WHERE segment1 = '14337';
SELECT line.* FROM PO_REQUISITION_HEADERS_ALL header,PO_REQUISITION_LINES_ALL line
WHERE header.REQUISITION_HEADER_ID = line.REQUISITION_HEADER_ID
AND header.segment1 = '14337';
SELECT * FROM PO_REQUISITION_LINES_ALL line,PO_REQ_DISTRIBUTIONS_ALL dis
WHERE line.REQUISITION_LINE_ID = dis.REQUISITION_LINE_ID
AND line.REQUISITION_HEADER_ID IN (SELECT REQUISITION_HEADER_ID FROM PO_REQUISITION_HEADERS_ALL WHERE segment1 = '14337');
2.AutoCreate
AutoCreate用于把PR转换成PO
路径：Purchasing > AutoCreate
注：如果查不到PR，看看Buyer或者Ship-To是否输入正确，可以清掉这两个字段再查
这里使用Automatic模式来生成PO，接下来会弹出窗口，输入必要的采购订单的必要信息，比如供货方，币别...
