  SAP Error Message:
  WZRE_PRX102 ProductStandardID &1: EAN &2 with SchemeAgencyID &3 already mapped
  
  Cause:
  This error occurs when you try to assign or map a product identifier (such as an EAN/GTIN) to a product in SAP, but the same identifier (EAN) with the same SchemeAgencyID (which identifies the coding scheme, e.g., GS1) is already assigned to another product in the system.
  
  ProductStandardID &1: The product for which you are trying to assign the EAN.
  EAN &2: The barcode or product identifier you are trying to assign.
  SchemeAgencyID &3: The identifier of the coding scheme (e.g., GS1).
  
  SAP enforces uniqueness of product identifiers within the system to avoid conflicts and ensure data integrity. Therefore, the same EAN cannot be assigned to multiple products under the same coding scheme.
  
  Solution:
  
  
  Check Existing Assignments:
  
  Identify the product that currently has the EAN &2 assigned under SchemeAgencyID &3.
  You can use transaction codes like MM03 (Display Material) or WZRE (if available) to check product identifiers.
  Alternatively, check the relevant tables such as MARA (general material data) or MARC (plant data), or specific tables for product identifiers like WZRE_PRODUCT_ID or similar, depending on your SAP version and module.
  
  
  
  Resolve Duplicate Assignment:
  
  If the EAN is incorrectly assigned to another product, correct or remove the assignment from the other product.
  If the EAN should be assigned to the current product, first delete or unassign it from the other product.
  
  
  
  Use Correct SchemeAgencyID:
  
  Verify that the SchemeAgencyID is correct and consistent with your organization's coding standards.
  Sometimes, different coding schemes might be confused, so ensure you are using the right SchemeAgencyID.
  
  
  
  Data Cleansing:
  
  If this is a data migration or master data upload scenario, ensure your source data does not contain duplicate EANs assigned to multiple products.
  Cleanse and validate data before upload.
  
  
  
  Consult Master Data Governance:
  
  If your organization uses Master Data Governance (MDG) or a similar tool, check the workflows and validations that might be enforcing this uniqueness.
  
  
  
  
  Related Information:
  
  EAN (European Article Number) is a barcode standard widely used for product identification.
  SchemeAgencyID typically refers to the coding scheme authority, e.g., GS1.
  SAP requires unique product identifiers to avoid confusion in procurement, sales, inventory, and logistics.
  This error is common during master data creation, data migration, or integration with external systems.
  If you are using SAP S/4HANA or SAP ERP, the exact table or transaction might differ, but the principle remains the same.
  
  
  Summary:
  
  
  
  Aspect
  Details
  
  
  
  
  Error
  Product identifier (EAN) already assigned to another product under the same scheme.
  
  
  Cause
  Duplicate assignment of the same EAN and SchemeAgencyID to multiple products.
  
  
  Solution
  Identify and remove the duplicate assignment; ensure unique EAN per product.
  
  
  Check Tools
  Transactions: MM03, WZRE; Tables: MARA, WZRE_PRODUCT_ID (or equivalent).
  
  
  Additional
  Validate data during upload/migration; confirm correct SchemeAgencyID is used.
