USMD1B236 - Details

• The SAP error message USMD1B236, which states "Range node overlaps with range node &1 &2 under node &3 &4," typically occurs in the context of SAP Master Data Governance (MDG) when there are overlapping ranges defined for a specific attribute in a data model. This can happen when you are trying to create or modify a range node in a hierarchy, and the new range you are trying to define overlaps with an existing range.
  
  Cause:
  
  Overlapping Ranges: The primary cause of this error is that the range you are trying to define overlaps with an existing range node. For example, if you have a range defined as 1-10 and you try to create another range as 5-15, this will trigger the error because the ranges overlap.
  Incorrect Data Entry: Sometimes, this can be due to incorrect data entry where the start and end values of the range are not properly defined.
