• What is the cause and solution for SAP error message WE220 - The EAN & is not numeric ?

  SAP Error Message:
  WE220 - The EAN & is not numeric
  
  
  Cause:
  The error message WE220 occurs during the processing of an IDoc when the system expects an EAN (European Article Number) or GTIN (Global Trade Item Number) to be numeric, but the data received contains non-numeric characters.
  EAN/GTIN numbers are standardized numeric codes used to identify products uniquely. SAP expects these fields to contain only digits (0-9). If the IDoc segment contains alphabetic characters, special characters, or spaces in the EAN field, the system raises this error.
  
  Where it occurs:
  
  During IDoc inbound processing (e.g., ORDERS, INVOIC, DESADV messages).
  In segments like E1EDP01 or E1EDP19 where EAN/GTIN is mapped.
  When validating the EAN field against the expected numeric format.
  
  
  Typical Scenario:
  
  The sender system sends an IDoc with an EAN field containing letters or special characters.
  SAP tries to convert or validate the EAN field as numeric.
  The validation fails, triggering WE220.
  
  
  
  Solution:
  
  
  Check the IDoc Data:
  
  Use transaction WE02 or WE05 to display
