Data Cleaning

Data Cleaning, Before It Becomes a Migration Problem

Dirty source data is the single biggest cause of migration slippage. We cleanse, standardize, and de-duplicate SAP master and transactional data before it ever reaches a load cycle, so your migration timeline isn't spent firefighting bad records.

Overview

What SAP Data Cleaning Involves

Data cleaning is the remediation of source data quality issues (duplicates, inconsistent formats, missing mandatory fields, and orphaned records) before extraction and load begin.

Duplicate Resolution

Identifying and merging duplicate master records (vendors, customers, materials) that would otherwise load as separate objects.

Format Standardization

Correcting inconsistent date formats, unit-of-measure entries, and field-length mismatches across source systems.

Mandatory Field Completion

Flagging and resolving missing values in fields the target SAP environment requires to accept the load.

Orphan & Obsolete Record Cleanup

Removing records with no valid downstream reference, so migrated data doesn't carry legacy clutter forward.

Dirty data is the #1 cause of migration timeline slippage, not scope, not tooling, not resourcing. Catching data quality issues at the cleansing stage is far cheaper than catching them during a failed mock load, or worse, during cutover weekend.

Our Process

How We Run a Data Cleaning Workstream

1

Data Profiling

We run source data through profiling checks to surface duplicates, format inconsistencies, and completeness gaps before touching a single record.

2

Rule Definition & Sign-Off

Cleansing rules (merge logic, formatting standards, exclusion criteria) are documented and approved with your functional team before execution.

3

Cleansing Execution

Rules are applied against the full data set, with an audit trail of every correction for traceability.

4

Quality Sign-Off

Cleansed data is re-profiled against agreed quality thresholds before it's handed off to mapping and load.

Common Questions About Data Cleaning

SAP data cleaning is the process of identifying and fixing source data quality issues, such as duplicate records, inconsistent formats, missing mandatory fields, and orphaned records, before that data is extracted and loaded into a target SAP environment.
Dirty source data is one of the most common causes of SAP migration delays. Issues that aren't caught before load tend to surface during mock loads or, worse, during cutover, where they are far more expensive to fix.
Common issues include duplicate master records for vendors, customers, or materials, inconsistent date and unit-of-measure formats across source systems, missing values in fields the target SAP system requires, and obsolete or orphaned records.
Yes. Etlzone can run data cleansing as a standalone engagement ahead of a broader SAP migration program, or as the first phase of a full end-to-end migration workstream.
Cleansing rules are documented and signed off before execution. Every correction is applied with an audit trail, so changes remain traceable for compliance and sign-off purposes.
