• What is the cause and solution for SAP error message WSFP_MESSAGE012 - Material group &1 is not assigned to a hierarchy ?

  The SAP error message:
  WSFP_MESSAGE012: Material group &1 is not assigned to a hierarchy
  
  
  Cause:
  This error occurs when a material group (material group code &1) is used in a process that requires the material group to be assigned to a material group hierarchy, but it is not assigned. Material group hierarchies are used in various SAP modules (e.g., Logistics, Sales, and Distribution, or Warehouse Management) to structure material groups for reporting, planning, or process control.
  For example, in SAP Warehouse Management (WM) or Extended Warehouse Management (EWM), material groups must be assigned to a hierarchy to enable certain functions like categorization, reporting, or process determination.
  
  
  Solution:
  
  
  Assign the Material Group to a Material Group Hierarchy:
  
  
  Go to the transaction where material group hierarchies are maintained. This depends on the module:
  
  For SAP ERP Logistics: Use transaction OMS2 (Define Material Group Hierarchy).
  For SAP EWM: Use the relevant IMG path or EWM customizing to assign material groups to hierarchies.
