Process audit before SAP S/4HANA migration: Clean master data before the new setup
Migrating unvetted records into S/4HANA replicates legacy friction faster. Clean master data and open transaction backlogs before consultants write technical blueprints.

The hidden risk of unvetted migrations
Many enterprises treat S/4HANA migration simply as a hardware upgrade or database migration. If master records in legacy SAP ECC are inconsistent, the new environment will encounter immediate operational roadblocks right after go-live.
S/4HANA introduces strict validation constraints, specifically the Business Partner (BP) model combining vendor and customer profiles. Bypassing cleanup upfront triggers persistent errors during cutover execution.
Three areas requiring immediate cleanup
Start by reviewing vendor and customer records: remove duplicate entries, verify tax IDs, and confirm banking details. Next, standardize material units of measure and retire obsolete item numbers.
Finally, clear open transaction backlogs. Lingering purchase orders or unsettled invoices from prior years must be reconciled and closed in ECC prior to extraction.
Involve business operations from day one
IT manages migration scripts, but warehouse leads, purchasing officers, and accountants know which suppliers are active and which inventory items are obsolete.
Establish a cross-departmental data audit team at the start of planning. Cleaning data early costs significantly less than troubleshooting corrupted transaction history post-launch.
