In the intricate landscape of SAP data management, the SAP CDPOS tables play a pivotal role as custodians of change, offering an invaluable repository of historical alterations to critical business data.

Short for “Change Document Positionen,” CDPOS tables form the bedrock of SAP’s Change Document system, capturing the who, what, when, and how of every modification made within the SAP environment.

As organizations increasingly prioritize transparency, compliance, and the ability to trace the evolution of their data, understanding and effectively leveraging CDPOS tables become essential. From querying historical changes to securing data integrity, CDPOS tables fortify the integrity and auditability of SAP data landscapes and ensure secure data management practices.

This article discusses the main purpose of CDPOS tables in SAP, how they enable the dynamic creation and exchange of critical change documents, and where our team of SAP consultants can come in to help.

What is a CDPOS Table in SAP?

The SAP CDPOS table is a critical component of the SAP Business Connector (BS) system for storing change documents. These change documents capture and record modifications made to data in various SAP modules, providing a historical log of changes made to key fields, when the changes occurred, and by whom.

CDPOS tables store critical change document details, including the object class, field name, old and new object value, user ID, date and time of change, and the type of operation (insert, update, delete).

For example, if a custom SAP program were to perform a change but not store the associated change logs, a user could leverage SAP CDPOS tables to check for change documents and logs after the change has already been executed. This way, organizations can review, consult, and backtrack changes as needed to validate specific changes.

Understanding the Differences Between CDHDR and CDPOS Tables

The CDPOS table is often associated with the Change Document Header (CDHDR) table, which contains general information about the change document, such as the object type, transaction code, and change document number. CDHDR provides a link to CDPOS, where detailed changes for specific fields are recorded and stored.

Here are a few key differentiating factors between table CDPOS and table CDHDR in SAP:

Primary Key Composition

Primary key composition plays an integral role in ensuring each change document uniquely identifies change document positions associated with a particular header or data element.

The primary key of CDPOS includes fields like object type, document number, document year, change number, and position. However, The primary key of CDHDR is typically composed of fields such as object type, document number, and document year, uniquely identifying a specific change document.

Information Scope

While both tables store information about changes made to SAP documents or the system as a whole, each table provides different levels of detail in each change document.

CDPOS stores detailed information about changes to individual fields within the objects tracked by change documents, such as the field name, old value, new value, and the type of operation.

CDHDR contains more generalized information about change documents, such as the object type, transaction code, document number, user who made the change, and the date and time of the change.

Table Structure

While CDHDR and CDPOS tables both exist to store critical information and header details from a change or contract document, they offer differing structural complexities.

On the one hand, CDPOS is a transparent table that stores detailed position-level data for change documents and holds the specifics of the changes made to individual fields, forming a one-to-many relationship with CDHDR.

Conversely, CDHDR acts as a header table linking to the specific change details in CDPOS and has a more generalized structure, capturing information common to all change documents.

List of Common Fields in CDPOS SAP Tables

Here’s a short list of the most common SAP CDPOS fields and their descriptions:

  • MANDANT: Client
  • OBJECTID: Object value
  • OBJECTCLAS: Object class
  • TABKEY: Change table record key
  • TABNAME: Table name
  • FNAME: Field name
  • UNIT_OLD: Change documents, unit referenced
  • UNIT_NEW: Change documents, unit referenced
  • VALUE_OLD: Old contents of changed field
  • VALUE_NEW: New contents of changed field

Common Use Cases for CDPOS Tables

Here’s a closer look at a few key use cases for a CDPOS table in SAP:

Audit Trail and Compliance Tracking

CDPOS SAP tables play a pivotal role in establishing a robust audit trail and facilitating more efficient compliance tracking, offering a reliable source for conducting audit processes, ensuring accountability, and maintaining compliance with regulatory obligations.

Particularly useful for organizations in industries with complex regulatory requirements, CDPOS SAP tables make it easier to improve data integrity and traceability and establish better control over core compliance processes.

Historical Data Analysis

By storing historical data in a single, unified CDPOS table, organizations are empowered to facilitate in-depth historical analysis of any existing contract, change, or accounting document.

Historical data analysis capabilities enable users to analyze the evolution of their most important business data over time, understand key change patterns, gain comprehensive insight into the progression of core business entities, and drive more informed decisions across teams.

Change Log for Reporting

Companies can leverage critical data stored in CDPOS tables to create comprehensive change logs that highlight specific changes made to existing fields.

As a complete data source for generating intelligent change logs, CDPOS SAP tables make it easier to visualize past data modification events, identify trends and patterns, and generate comprehensive reports.

Whether for internal reporting needs or external stakeholder validation, change logs derived from CDPOS SAP tables enhance transparency and accountability in core reporting practices.
