• What is the cause and solution for SAP error message KN455 - Assign only sequential items to a group ?

  The SAP error message KN455 ("Assign only sequential items to a group") typically occurs in the context of managing customer master data or sales documents in SAP. This error indicates that the system expects items in a certain sequence, but the items being processed do not meet this requirement.
  
  Cause:
  The error is usually caused by one of the following reasons:
  
  Non-sequential Item Numbers: The items you are trying to assign to a group are not in a sequential order. For example, if you are trying to group items 1001, 1003, and 1004, the presence of 1002 would be necessary for them to be considered sequential.
  Incorrect Grouping Logic: The grouping logic defined in the system may require that items be assigned in a specific order or range, and the current selection does not comply with that logic.
  Data Entry Errors: There may be a mistake in the data entry where items were incorrectly numbered
