  The SAP error message M3535 ("First specify the main EAN for the unit &") typically occurs in the context of material management, particularly when dealing with product master data and packaging information. 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. The main EAN is essential for identifying the product in various processes, such as sales, inventory management, and logistics.
  Solution:
  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.

  Save Changes:

  Related Information:
  
  EAN Types: There can be multiple EANs associated with a material (e.g., different packaging sizes), but the system requires a main EAN to be defined.
