W0005 - Details

• SAP Error Message:
  W0005 Maintain material group hierarchy level
  
  
  Cause:
  This warning message appears when you try to maintain or assign a material group but the corresponding material group hierarchy level has not been defined or maintained in the system. Material groups in SAP are structured hierarchically, and each level of the hierarchy must be set up before you can assign material groups to it.
  In other words, the system expects that the hierarchy levels for material groups are already created and maintained in the IMG (Implementation Guide) or relevant customizing settings. If these hierarchy levels are missing or incomplete, the system issues this warning.
  
  Explanation:
  
  Material groups are used to classify materials for reporting, pricing, and other business processes.
  They are organized in a hierarchy (e.g., Level 1, Level 2, Level 3, etc.).
  Before assigning a material group to a certain level, the hierarchy level itself must be defined.
  This message reminds you to maintain the hierarchy levels
