IDCN120 - Details

• The SAP error message IDCN120, which states "Select only one node. &1 nodes selected," typically occurs in the context of a hierarchical structure or tree view in SAP, where the system expects the user to select only a single node (or item) but detects that multiple nodes have been selected instead.
  
  Cause:
  
  Multiple Selections: The user has selected more than one node in a tree structure or hierarchy when the system only allows for a single selection.
  User Interface Limitation: The specific transaction or application may be designed to operate on a single node at a time, leading to this error when multiple nodes are selected.
  
  
  Solution:
  
  Deselect Nodes: Go back to the selection screen and ensure that only one node is selected. You can usually do this by clicking on the desired node while holding down the Ctrl key (to deselect others) or by using the mouse to click on a single node.
