Required Business analyst now with SQL, Excel, Inventory Allocation.

 Job Description:

About the Role:

• We are looking for a Business Analyst to support the migration of client’s inventory allocation control rules from the legacy ERP system into a new unified Allocation Rules Engine within the WMS.
• This is a detail-oriented, data-focused role working closely with the client’s operations and IT teams to ensure accurate rule translation and validated migration outcomes.

 Key Responsibilities:

• Analyze legacy ERP allocation rule configurations across 14 source tables and document current-state logic, data patterns, and known anomalies
• Build and maintain source-to-target mapping documentation, translating legacy entity-pair records into the attribute-based rule structure of the new engine
• Identify records requiring consolidation — grouping multiple legacy rows into single unified rules where business logic allows
• Flag conflicting, contradictory, or inactive source records for stakeholder review and resolution prior to migration
• Support migration script validation by reconciling migrated rule counts, configurations, and outputs against source data
• Design and execute data migration test cases to verify that the new rule engine produces identical blocking behavior to the legacy system across key scenarios
• Maintain a migration tracker covering mapping status, open data issues, decisions made, and sign-off accountability
• Collaborate with business stakeholders to clarify rule intent where source data is ambiguous or undocumented

 Required Skills & Experience:

• 7 years in a Data Analyst or data migration role, preferably within supply chain, logistics, or distribution
• Strong proficiency in Excel or SQL for data analysis, mapping, and reconciliation work
• Proven experience delivering source-to-target mapping documentation in a system migration or data conversion context
• Comfortable interpreting structured configuration data and translating it into functional business logic
• Organized and methodical — able to manage large volumes of mapping records with precision and traceability

Nice to Have:

• Familiarity with ERP or WMS platforms in a supply chain environment
• Experience with UAT or migration
