EAN stands for European Article Number, which is a barcode standard used for identifying products.
  Cause:
  This error message usually arises when you are trying to perform an action related to a material that requires a main EAN to be specified, but it has not been set up in the material master data.

  To resolve this error, you need to ensure that the main EAN is specified for the material in question. Here are the steps to do this:
  
  
  Access Material Master Data:
  
  Go to the transaction code MM02 (Change Material) or MM01 (Create Material) in SAP.
