    B015Duplicate Account in File

    The same account appears multiple times in the file

    Affected Field
    #4Account Number

    Description

    Common Causes

    • Data extraction pulling duplicate records
    • Multiple base segments for same account
    • File concatenation creating duplicates
    • Source system data quality issues

    How to Fix

    1. 1Deduplicate records before file generation
    2. 2Use unique constraint on account number per file
    3. 3Review data extraction logic
