• What is the cause and solution for SAP error message W-078 - Select incorrect hierarchy nodes ?

  SAP Error Message:
  
  W-078 Select incorrect hierarchy nodes
  
  Cause:
  This warning message typically occurs when a user selects hierarchy nodes in a way that is not allowed or inconsistent with the expected hierarchy structure in SAP. For example, in reports or planning functions where hierarchical data is involved (such as in Profit Center Accounting, Cost Center Accounting, or other controlling modules), selecting nodes that do not logically fit or are not valid for the operation can trigger this warning.
  Common causes include:  
  
  Selecting both parent and child nodes simultaneously when only one level is allowed.  
  Selecting nodes that belong to different hierarchies or incompatible branches.  
  Selecting nodes that are not active or valid in the current context.  
  Using an incorrect or outdated hierarchy version.
  
  
  Solution:
  To resolve the W-078 warning, consider the following steps:
  
  
  Check the hierarchy selection:  
  
  Ensure that you select only valid nodes according to the hierarchy rules.  
  Avoid selecting both parent and child nodes simultaneously if the system expects only one level.  
  Select nodes from the correct hierarchy version and ensure it is active.
  
  
  
  Use the hierarchy selection tool properly:  
  
  Use the standard SAP hierarchy selection dialogs or tree views to pick nodes rather than manual input.  
  Verify that the nodes you select are consistent and belong to the same hierarchy.
  
  
  
  Verify hierarchy setup:  
  
  Check the hierarchy definition in transaction codes like KSH1 (Create Hierarchy), KSH2 (Change Hierarchy), or KSH3 (Display Hierarchy) for controlling hierarchies.  
  Ensure the hierarchy is correctly maintained and active.
  
  
  
  Consult documentation or SAP notes:  
  
  Sometimes, specific modules or reports have particular restrictions on hierarchy node selection.  
  Check SAP Notes or module-specific documentation for any known issues or additional guidance.
