• What is the cause and solution for SAP error message G0020 - Select only one subtree (only single processing possible) ?

  The SAP error message G0020 ("Select only one subtree (only single processing possible)") typically occurs in the context of hierarchical data processing, such as when working with organizational structures, cost centers, or other tree-like data structures in SAP. This error indicates that the system expects the user to select only one subtree for processing, but multiple subtrees have been selected.
  Cause:
  
  Multiple Selections: The user has selected more than one subtree in a hierarchical structure when the system only allows processing of a single subtree at a time.
  Incorrect User Action: The user may have inadvertently selected multiple nodes or branches in the hierarchy.
  System Configuration: In some cases, the configuration of the SAP system may restrict certain operations to single subtree processing.
  
  Solution:
  
  Select a Single Subtree: Ensure that you only select one subtree for processing. You can do this by clicking on a single node or branch in the hierarchy.
  Deselect Other Selections: If you have multiple selections, deselect the additional nodes or branches so that only one subtree remains selected.
  Check for Filters: If applicable, check any filters or settings that might be affecting your selection and adjust them accordingly.
  Review Documentation: Consult the relevant SAP documentation or help resources for the specific transaction or module you are working with to understand the expected selection behavior.
