  WSTI_DOC007 – Enter either material group or material group hierarchy
  
  Cause:
  This error occurs when you are trying to process or post a document (often in SAP WM, EWM, or related logistics modules) and the system requires you to specify either a Material Group or a Material Group Hierarchy, but neither has been entered. The system needs one of these fields to correctly classify or process the material data.
  
  The message indicates that both fields are empty or missing.
  The system logic expects at least one of these fields to be filled to proceed.
  
  
  Solution:
  
  Enter either a Material Group or a Material Group Hierarchy in the relevant input field.
  Check the screen or transaction where the error appears and provide the required data.
  If you are unsure which to enter:
  
  Material Group: A specific group code assigned to materials.
  Material Group Hierarchy: A higher-level grouping that includes multiple material groups.
  
  
  If the fields are supposed to be defaulted or derived automatically, check the configuration or master data to ensure that the material master or related settings are correctly maintained.
  If you are using a custom program or interface, verify that the input data includes one of these fields.
  
  
  Related Information:
