• What is the cause and solution for SAP error message CJ426 - Highest element of selected hierarchy reached ?

  The SAP error message CJ426 "Highest element of selected hierarchy reached" typically occurs in the context of project management within SAP, particularly when working with project structures and hierarchies in the Project System (PS) module. This error indicates that the user is trying to perform an action that is not allowed at the current level of the project hierarchy.
  Cause:
  
  Hierarchy Level: The error usually arises when a user attempts to assign or manipulate a project element (like a WBS element) at a level that is not permitted. For example, trying to assign costs or resources to a project element that is at the highest level of the hierarchy (like the project itself) instead of a lower-level WBS element.
  Incorrect Selection: The user may have selected a project or WBS element that is not appropriate for the action they are trying to perform.
  Authorization Issues: Sometimes, the error can also be related to authorization settings that prevent actions at certain levels of the hierarchy.
  
  Solution:
  
  Check Hierarchy Level: Ensure that you are working at the correct level of the project hierarchy. If you need to assign costs or resources, make sure you are selecting a lower-level WBS element rather than the project itself.
  Review Project Structure: Navigate through the project structure to confirm that you are selecting the right element for the action you want to perform.
  Use the Correct Transaction: Make sure you are using the appropriate transaction code for the action you are trying to perform. For example, if you are trying to create or change a WBS element, use the correct transaction (like CJ20N for project planning).
  Consult Documentation: Refer to SAP documentation or help files for guidance on the specific action you are trying to perform and the hierarchy requirements.
  Authorization Check: If you suspect that authorization might be an issue, check with your SAP security team to ensure you have the necessary permissions to perform actions at the desired hierarchy level.
