Overview

XLA_CMP_STRING_PKG is a private PL/SQL package owned by the APPS schema in Oracle E-Business Suite. Its declared purpose, per the package header, is to contain "all the logic required to handle the text generated by the compiler." In the context of the Subledger Accounting (XLA) architecture, this compiler is the Subledger Accounting Program that generates accounting program code from application accounting definitions. The package therefore provides low-level string and text-manipulation utilities used by the XLA code generation engine rather than by any end-user business flow directly. It is classified in ETRM as "OTHER," signifying that it is an internal, non-public API rather than a supported extension point. The package is declared AUTHID CURRENT_USER, so its unqualified database object references resolve against the invoker's schema rather than the owner's. Because it touches generated source text, its routines are oriented toward line-at-a-time processing, token substitution, and assembly of large text bodies.

Key Procedures and Functions

  • CREATESTRING — Transforms CLOB lines whose length exceeds 255 characters into a list of lines that do not exceed 255 characters each. This is the foundational routine for splitting generated compiler output into chunks suitable for further processing.
  • CONCATTWOSTRINGS — Concatenates two string values into a single combined result, supporting the incremental assembly of generated text.
  • ADDNEWLINE — Appends a line-break to a string buffer, allowing generated code fragments to be accumulated as properly delimited lines.
  • TRUNCATE_LINES — The routine associated with the user's search term. It trims or limits line content, operating on the array of line segments produced by the string-splitting logic so that each element conforms to the expected maximum width before further handling.
  • REPLACE_TOKEN — Performs token substitution within CLOB variables. The package history records that this routine was added on 21-Sep-2004 specifically to handle REPLACE operations on CLOB data, at the same time the earlier LONG VARCHAR variables were replaced with CLOBs.

The package also defines the private type VARCHAR2S and the global variable g_null_varchar2s, both used internally by these routines.

Tables Accessed

ETRM does not document any application tables for this package. The only referenced objects are the PL/SQL-supplied packages DBMS_SQL and PLITBLM, accessed through APPS synonyms. DBMS_SQL supplies the VARCHAR2S associative array type used to model collections of lines, while PLITBLM provides the underlying line and token handling utilities. No XLA base tables, transaction tables, or interface tables are recorded, consistent with the package functioning purely as an in-memory text utility.

Usage Notes

XLA_CMP_STRING_PKG is not invoked from Oracle Forms or from concurrent programs directly by end users. It is called by the XLA compiler and related code-generation components during the creation and validation of generated accounting program text. ETRM records that the package is referenced by twelve other packages, which confirms its role as a shared internal dependency. Because the procedures are declared in the package specification but the package is private and unsupported, customizations should avoid calling these routines directly; they are subject to change without notice between 12.1.1 and 12.2.2. Developers investigating generated code issues typically encounter this package indirectly, for example when tracing how compiler output is split into lines or how substitution tokens are resolved.
