Operational Intelligence

Failure patterns in SAP ECC data migration

Ignoring these common pitfalls can lead to significant post-migration operational debt, financial reporting errors, and a breakdown in consumer trust. We proactively identify and mitigate these risks.

Inconsistent Material Master Data

Symptoms

  • Production orders failing due to missing BOM components.
  • Incorrect inventory valuations appearing in finance reports.
  • Procurement issues from misaligned units of measure.
  • Customer orders placed for non-existent products.

Root Causes

  • Lack of a central data governance framework.
  • Insufficient data cleansing from source systems.
  • Poorly defined mapping rules for material characteristics.
  • Over-reliance on manual data entry during migration.
SAP ECC MMLegacy MRPPLMWMS

Impact: Significant manufacturing delays, costing inaccuracies, and customer service failures post-cutover. This breaks first.

Cogent Approach: We establish a rigorous material master data governance strategy, including data profiling, standardisation, and automated validation rules before migration. Mock loads are essential.

Financial Data Reconciliation Gaps

Symptoms

  • Trial balance discrepancies between legacy and new SAP ECC GL.
  • Accounts Receivable/Payable balances not matching sub-ledgers.
  • Audit findings revealing unexplainable variances in financial statements.
  • Delayed month-end close due to data integrity investigations.

Root Causes

  • Incomplete mapping of legacy chart of accounts to SAP ECC.
  • Failure to consider all transactional line items during migration.
  • Lack of a clear reconciliation methodology agreed pre-cutover.
  • Insufficient testing of financial migration processes.
SAP ECC FILegacy GLARAP

Impact: Regulatory non-compliance, inability to produce accurate financial statements, and a loss of trust in the new ERP system. Most brands realise too late how critical this is.

Cogent Approach: Our consultants define a granular reconciliation strategy, focusing on source data completeness and granular mapping. We guide finance teams through iterative mock migrations and balance verification.

Open Order & Delivery Disruption

Symptoms

  • Customers unable to track existing orders after cutover.
  • Warehouse unable to fulfil open orders, leading to backlog.
  • Duplicate orders created in SAP ECC from incomplete legacy data.
  • Incorrect pricing or delivery terms applied to migrated orders.

Root Causes

  • Ambiguous definition of 'open' orders at cutover.
  • Lack of status mapping for sales documents.
  • Insufficient testing of order-to-cash process with migrated data.
  • Poor coordination between commercial and logistics teams.
SAP ECC SDOMSWCSCRM

Impact: Direct revenue loss, damaged customer relationships, and significant operational recovery costs. Trust in fulfilment collapses quickly.

Cogent Approach: We focus on a clear cutover strategy for open sales and purchase orders, ensuring status preservation and a staged approach to live transactions. Hypercare post-cutover is crucial.

Elevating SAP ECC data intelligence

A successful SAP ECC data migration sets the stage for advanced operational intelligence. We position your migrated data not just for accurate transactions but also for future analytical capabilities, enabling better forecasting, inventory optimisation, and customer insights.

The goal is a data foundation that supports agile decision-making, moving beyond historical reporting to predictive insights. This means standardising core data entities and ensuring integration points support high-quality data flows post-migration, feeding future AI tools.

We help identify and implement the right data warehousing and business intelligence tools post-migration, ensuring your SAP ECC data becomes a strategic asset, easily consumable by analytical platforms like Power BI, and ready for advanced AI analytics.

Knowledge Base

Frequently Asked Questions

General Migration Concerns
What is the typical timeline for an SAP ECC data migration?
The timeline varies significantly based on data volume, complexity, and source system landscape. For retailers, it can range from 6 months to over 18 months. We focus on phased approaches to reduce risk and manage business impact.
How do you ensure data accuracy during migration?
We employ a multi-layered approach: initial data profiling, strict data cleansing and transformation rules, iterative mock loads, automated validation scripts, and comprehensive reconciliation checks with finance teams.
What data should we migrate beyond just master data?
Retailers typically need to migrate master data (customer, vendor, material), open transactions (sales orders, purchase orders), and critical financial balances. Historical transactional detail is often summarised or archived rather than fully migrated due to volume.
Operational Impact & Cutover
How much business downtime is required during cutover?
Minimising downtime is a key objective. We plan for a controlled cutover window, often during off-peak hours or weekends, with detailed runbooks and rollback plans to ensure critical operations resume swiftly.
What happens if we discover data errors post-migration?
Our approach includes a hypercare period with dedicated support to address and resolve any post-cutover data discrepancies or operational issues promptly, with clear escalation paths and resolution protocols.
How do you handle open sales orders and purchase orders during migration?
We develop specific strategies for open documents, often involving migrating only active orders/PO's with careful status mapping to ensure continuity of fulfilment and procurement processes without duplication or loss of data.
