• What is the cause and solution for SAP error message WE307 - It is only useful to specify a length for numeric EANs ?

  Certainly! Here's a detailed explanation for the SAP error message WE307:
  
  SAP Error Message: WE307
  Message Text:
  It is only useful to specify a length for numeric EANs
  
  Cause
  This error occurs during IDoc processing or EDI data mapping when defining or handling EAN (European Article Number) fields. The system expects that the length specification for EAN fields should only be provided if the EAN is numeric.
  
  EAN fields are typically numeric codes used for product identification.
  If a length is specified for an EAN that is not numeric (e.g., alphanumeric or contains special characters), the system raises this warning/error.
  This is because specifying a length for non-numeric EANs is not meaningful or supported by the system.
  
  
  When does it occur?
  
  During IDoc segment or field definition in WE31 or WE30.
  When mapping or validating EAN fields in EDI transactions.
  When customizing or extending IDoc segments that include EAN fields.
  When using message types or segments that include EAN fields with length restrictions.
