Overview

XDP_INTERFACES_OD_VUHK is an Oracle Application Object Library PL/SQL package owned by the APPS schema that forms part of the Oracle E-Business Suite service and order management integration layer. Its purpose is to expose customer-definable extension points around the standard Get_Order_Details API. The package declares two public procedures, Get_Order_Details_Pre and Get_Order_Details_Post, which are deliberately empty hook bodies intended to be replaced or supplemented by customer customization. The "_VUHK" suffix identifies it as a view/user hook stub, a convention Oracle uses for components that ship without business logic so that implementers can add site-specific code without modifying Oracle-owned objects.

The package is declared with AUTHID CURRENT_USER, meaning that at runtime the procedures execute with the privileges of the invoking session rather than the definer's privileges. This is significant because it allows the calling application to resolve unqualified names using the caller's schema context.

Key Procedures and Functions

• Get_Order_Details_Pre — A hook invoked immediately before the Get_Order_Details API executes. Its documented purpose is to let a customer inject customization logic prior to order retrieval. All parameters are defined as IN OUT NOCOPY, so the procedure can modify order identifiers and the order data structures that the subsequent API call relies on. A blank stub ships with the product; customization is applied by replacing the body.
• Get_Order_Details_Post — The complementary hook, invoked immediately after the Get_Order_Details API completes. It permits post-processing of the returned header, parameter, line item, and line parameter collections, along with the raw data buffer, record count, and return code. Like the Pre hook, it ships empty and is intended to be overridden.

Both procedures operate on a consistent parameter family: order number, order version, and order ID as input/output keys, followed by typed collections from XDP_TYPES (SERVICE_ORDER_HEADER, SERVICE_ORDER_PARAM_LIST, SERVICE_ORDER_LINE_LIST, SERVICE_LINE_PARAM_LIST), a VARCHAR2 data payload, a numeric count, and a return code. No business logic is documented inside either stub.

Tables Accessed

The supplied metadata does not record any base tables accessed through APPS synonyms. This is expected for a hook package: the stubs contain no SQL, and any table access occurs only in customer-supplied implementations. Implementers adding logic to these procedures must therefore manage their own table references, respecting the AUTHID CURRENT_USER privilege model and avoiding direct writes to Oracle-owned service order tables.

Usage Notes

The package is referenced by one other package within the EBS code base, which acts as the caller that fires the Pre and Post hooks around Get_Order_Details. Typical invocation paths include service order entry and retrieval flows in Oracle Depot Repair, Field Service, and related order management modules, accessed through Oracle Forms, concurrent programs, or external integration code that calls the wrapper API.

Because the shipped bodies are empty, customization should be applied through the supported Oracle extension mechanism rather than by editing the delivered source. The ETRM classification for this object is OTHER, reflecting its role as a user exit rather than a documented business API. The header comment dates the source to 2005, and the package remains present across the 12.1.1 and 12.2.2 releases, retained for backward compatibility.
