• What is the cause and solution for SAP error message W7005 - Material group hierarchy level must have a value between 1 and 9 ?

  SAP Error Message:
  
  W7005: Material group hierarchy level must have a value between 1 and 9
  
  Cause:
  This warning message occurs when you try to assign or maintain a material group hierarchy level with a value outside the allowed range. In SAP, the material group hierarchy levels are defined to be between 1 and 9. If a level number less than 1 or greater than 9 is entered, the system triggers this warning.
  
  Explanation:
  
  Material groups in SAP are organized in a hierarchical structure.
  Each level in the hierarchy is numbered from 1 (top level) to 9 (lowest level).
  The system restricts the hierarchy levels to this range to maintain consistency and proper data structure.
  Entering a level number outside this range violates this rule, causing the warning.
  
  
  Solution:
  
  Check the material group hierarchy level you are trying to assign or maintain.
  Ensure that the hierarchy level number is between 1 and 9.
  Correct the level number if it is outside this range.
  Save the changes again.
