Description: 

AP_HOLDS_ALL contains information about holds that you or your Oracle Payables application place on an invoice. For non-matching holds, there is one row for each hold placed on an invoice. For matching holds, there is one row for each hold placed on an invoice-shipment match. An invoice may have one or more corresponding rows in this table. Your Oracle Payables application does not pay invoices that have one or more unreleased holds recorded in this table.

This table holds information referenced by the Invoice Holds window.

In the strictest sense, AP_HOLDS_ALL has no primary key. It is possible for your Oracle Payables application to place a certain type of hold on an invoice, then release it, then place another hold of the same type (if data changes before each submission of Payables Invoice Validation), which would result in a duplicate primary key. But for practical purposes, the primary key is a concatenation of INVOICE_ID, LINE_LOCATION_ID, and HOLD_LOOKUP_CODE.
