In master data management within SAP, as with all types of data, a fundamental principle applies: GIGO (Garbage In, Garbage Out). This concept essentially means that if the source data is inaccurate or incomplete, the processes and analytics derived from it will also be flawed.
Today, data is one of the most valuable assets for any organization and serves as a critical pillar in ensuring the efficient operation of an ERP system.
In this article, we will explore key strategies for achieving effective master data management in SAP and preparing your system for migration to the latest version. Additionally, we will look at how to streamline this entire process through solutions that integrate natively with the system while ensuring data quality is maintained after migration.
Data Quality as the Foundation for SAP Success
In the SAP ecosystem, master data management—whether related to materials, vendors, customers, or other domains—must be properly defined, structured, and aligned with business processes to ensure efficient and consistent operations across functional areas.
However, many organizations maintain overly complex data structures, often relying heavily on manual processes within the system. This leads to operational delays, support tickets, data duplication, inconsistencies, and wrong reports. The situation becomes even more critical when not all business units have access to up-to-date or consolidated information, directly impacting data quality and, consequently, the ability to make informed decisions.
When migrating from SAP ECC to leverage the full range of analytical, predictive, and process automation capabilities offered by SAP S/4HANA, it is essential to implement a clear master data management strategy. Such a strategy should ensure that data is correctly input, continuously cleansed, standardized, and governed by well-defined business rules.
Tips for More Effective Master Data Management in SAP
SAP ERP—whether in its ECC version or SAP S/4HANA—has established itself as one of the most powerful enterprise resource planning systems available. However, its full potential can only be realized if supported by best practices and appropriate tools that help maintain data consistency, structure, reliability, and alignment with business goals and processes.
Below are some essential guidelines your organization can begin applying today to achieve truly optimized master data management in SAP.
Standardization in Master Data Management in SAP
One of the most common mistakes in master data management is the lack of consistency in information. This frequently occurs, especially when the same data is entered differently in various operations/countries of the company.
For example, a product might be recorded in one area as “M8 Screw” and in another branch as “8 mm Screw.” Although both refer to the same material, the system does not recognize them as identical, resulting in duplicates, inconsistent codes, and, consequently, errors that cascade across other processes. This compromises data reliability and leads to operational inefficiencies.
The first step to mitigating this issue is to define clear rules for the naming conventions and data structure used when entering records into the system. This ensures that data is consistently captured, regardless of who creates it.
This involves setting mandatory fields, standardized formats (e.g., abbreviations, compose text from characteristics), as well as coherent prefixes and suffixes based on the type of data (material, vendor, etc.). Well-defined classification criteria are also essential. These practices make it easier for different users to enter the same product in an identical way, thus avoiding duplication.
Even so, due to the human factor, errors can still occur during these processes, even when naming conventions are already in place. Therefore, it is advisable to implement validation and quality control mechanisms at the data entry stage.
For instance, a review and approval process can be established, overseen by a designated data steward. Additionally, periodic reports can be generated to identify errors, duplicates, or inconsistencies in master data.
Governance and Access Control
As mentioned earlier, master data management can be significantly improved by assigning a dedicated person to oversee its proper administration. However, this alone is not enough: it is necessary to go a step further and define a clear governance structure with well-established roles and responsibilities regarding who can create, modify, and validate data.
Such controls not only help maintain data quality but also ensure that those involved in managing it are properly trained, thereby reducing the risk of errors and ensuring compliance with internal SAP data management standards.
With this role-based structure in place, data traceability is easier to maintain, and unauthorized or non-compliant modifications can be avoided. Responsible individuals should also perform ongoing reviews of data integrity. This involves not only identifying errors but also analyzing usage patterns, flagging obsolete records, and maintaining a clean, operationally aligned database.
To ensure rigorous control, full traceability of changes is essential. While SAP S/4HANA provides certain standard functionalities, without complementary tools, manual tracking mechanisms may need to be established. This includes recording information such as who entered the data, when, and why—facilitating future audits or corrections.
Automated Master Data Management in SAP
Upon migrating to the new system, master data management in SAP can benefit significantly from automation tools, especially those that reduce manual tasks during data creation, modification, and validation.
We recommend considering external solutions that integrate natively with SAP ECC and remain compatible with SAP S/4 HANA. Although these tools may entail an initial investment, they lead to substantial savings in the medium and long term by reducing errors, improving execution times, and enhancing overall data quality.
These tools enable data to pass through configurable validation approval workflows, automatically involving responsible users to ensure compliance with established rules. For example, solutions like the one we offer at Innova prevent the creation of incomplete, duplicate, or incorrect records from the outset, ensuring robust and reliable data input from the source.
Data Cleansing Prior to SAP S/4HANA Migration
The migration process should not be viewed merely as a technical upgrade, but rather as a strategic opportunity to comprehensively improve master data quality.
Before initiating the migration, it is essential to reassess the current state of the data and implement clear cleansing and maintenance policies. This ensures that the new platform operates smoothly, without carrying over legacy errors that could compromise its performance or data integrity.
In this context, we recommend implementing data pruning strategies—that is, migrating only those materials, vendors, customers, or data objects that, for example, have shown recent activity or meet minimum quality standards. This approach helps reduce database volume (and then, costs), lowers future maintenance efforts, and prevents the transfer of historical data issues into the new system.
Additionally, it is critical to focus on data quality, ensuring that the materials and records selected for migration are complete, properly structured, and accurately validated.
At Innova, we strongly advocate for conducting a thorough audit of master data prior to migration, identifying issues and defining cleansing rules based on factors such as:
- Periods of inactivity (to flag data as inactive)
- Detection of inconsistencies in key fields (e.g., inconsistent units of measure, batch management, or invalid valuation class)
- Deletion or block obsolete or duplicate records
This entire process reflects a shift from “GIGO” to “VIVO” (Valuable In, Valuable Out), ensuring that only relevant and high-quality data is migrated. It’s important to note that this philosophy should not be limited to the migration phase alone. A continuous master data maintenance plan should be implemented post-migration to keep the system clean, efficient, and aligned with business processes over time.
