• What is the cause and solution for SAP error message 42248 - Insertion on the same level is not allowed for root nodes ?

  The SAP error message 42248, "Insertion on the same level is not allowed for root nodes," typically occurs in the context of hierarchical data structures, such as when working with organizational units, cost centers, or other master data that has a parent-child relationship.
  
  Cause:
  This error arises when there is an attempt to insert a new node (e.g., a new organizational unit or cost center) at the same level as an existing root node. In hierarchical structures, root nodes are the top-level nodes, and the system does not allow the insertion of new nodes at the same level as these root nodes. This is because the hierarchy is designed to maintain a clear parent-child relationship, and root nodes should only have child nodes beneath them.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Hierarchy Structure: Review the existing hierarchy to understand the current structure of root nodes and their children.
