PO_DISTRIBUTIONS_ALL

PO_DISTRIBUTIONS_ALL contains accounting distribution information for a purchase order shipment line. You need onerow for each distribution line you attach to a purchase order shipment. There are four types of documents usingdistributions in Oracle Purchasing:

Standard Purchase Orders Planned Purchase Orders Planned Purchase Order Releases Blanket Purchase Order Releases

Each row includes the destination type, requestor ID, quantity ordered and deliverto location for the distribution. Oracle

Purchasing uses this information to record accounting and requisition information for purchase orders and releases.PO_DISTRIBUTIONS_ALL is one of five tables storing purchase order and release information. Some columns inPO_DISTRIBUTIONS_ALL contain information only if certain conditions exist:

If you autocreate this accounting distribution from a requisition, REQ_DISTRIBUTION_ID corresponds to the ID of therequisition distribution you copy on the purchase order. If you use a foreign currency on your purchase order,Oracle Purchasing stores currency conversion information in RATEand RATE_DATE. If you use encumbrance, GL_ENCUMBERED_DATE and GL_ENCUMBERED_PERIOD_NAME contain encumbranceinformation Oracle Purchasing uses to create journal entries in Oracle General Ledger. If you do not autocreate the purchase order from online requisitions, REQ_LINE_REFERENCE_NUM andREQ_HEADER_REFERENCE_NUM contain the requisition number and requisition line number of the corresponding paper

requisition. These two columns are not foreign keys to another table. If the distribution corresponds to a blanket purchase order release, PO_RELEASE_ID identifies this release. If SOURCE_DISTRIBUTION_ID has a value, the distribution is part of a planned purchase order release. If you cancel thedistribution, Oracle Purchasing automatically updates QUANTITY_CANCELLED or GL_CANCELLED_DATE. Oracle Purchasingalso enters UNENCUMBERED_AMOUNT if you use encumbrance
