• What is the cause and solution for SAP error message USMD1B236 - Range node overlaps with range node &1 &2 under node &3 &4 ?

  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.
  Hierarchy Structure Issues: If the hierarchy structure is not properly maintained, it can lead to conflicts in range definitions.
  
  Solution:
  
  Review Existing Ranges: Check the existing range nodes under the specified parent node (as indicated by &3 &4 in the error message). Identify the ranges that are causing the overlap.
  Adjust Ranges: Modify the range you are trying to create so that it does not overlap with existing ranges. Ensure that the start and end values are distinct and do not intersect with other defined ranges.
  Delete or Merge Ranges: If applicable, consider deleting or merging existing ranges that are causing the conflict if they are no longer needed.
  Validation: After making adjustments, validate the hierarchy to ensure that all ranges are correctly defined and do not overlap.
