How To Fix WP765 - No further data available, node cannot be expanded

SAP Error Message - Details

• Message type: E = Error

• Message class: WP - Messages from POS interface

• Message number: 765

• Message text: No further data available, node cannot be expanded

What causes this issue?

In the POS interface monitor all nodes under which further data can
exist are marked with the icon '+' for expansion. It is, however, not
possible to determine if more data actually exists below all nodes, as
this would take too long. Data is therefore only read for nodes which
you expand. The system determined that no further data exists below
the current node.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message WP765 - No further data available, node cannot be expanded ?

  Certainly! Here's a detailed explanation for the SAP error message WP765: No further data available, node cannot be expanded:
  
  Error Message:
  WP765 - No further data available, node cannot be expanded
  
  Cause:
  This error typically occurs in SAP when you try to expand a node in a hierarchical structure (such as a work breakdown structure (WBS), project structure, or organizational hierarchy) but there is no additional data or child nodes available under that node to display.
  Common causes include:
  
  The node you are trying to expand is a leaf node (i.e., it has no children).
  The data for the child nodes has not been created or maintained.
  The system is unable to retrieve further data due to authorization restrictions or data inconsistencies.
  The node is incorrectly defined or the hierarchy is incomplete.
  In some cases, the underlying data source or table does not contain further entries for that node.
  
  
  Where it occurs:
  
  Project System (PS) module when working with WBS elements.
  Organizational Management (OM) when expanding organizational units.
  Any hierarchical display or tree structure in SAP where nodes can be expanded.
  
  
  Solution:
  
  
  Check if the node is a leaf node:
  
  Verify whether the node you are trying to expand is supposed to have child nodes.
  If it is a leaf node, the message is expected behavior.
  
  
  
  Verify data completeness:
  
  Check if child nodes have been created and assigned properly.
  In Project System, use transaction codes like CJ20N (Project Builder) to verify the WBS structure.
  In Organizational Management, use PPOME or PP01 to check the org structure.
  
  
  
  Check authorizations:
  
  Ensure you have the necessary authorizations to view the child nodes.
  Lack of authorization can cause the system to not display further data.
  
  
  
  Check for data inconsistencies:
  
  Run consistency checks or reports to verify the integrity of the hierarchy.
  For example, in PS, use report RPSB0001 or similar to check WBS consistency.
  
  
  
  Technical checks:
  
  If the problem persists, check the underlying tables for the node and its children.
  Debug or check logs to see if there are errors fetching data.
  
  
  
  SAP Notes and Support:
  
  Search for relevant SAP Notes if this is a known issue with your SAP version.
  Sometimes patches or support packages fix related issues.
  
  
  
  
  Additional Information:
  
  This message is informational and indicates that the system cannot expand the node further because no data exists.
  It is not necessarily an error but a status message.
  If you expect child nodes but none appear, focus on data creation and maintenance.
  In custom developments or reports, ensure that the logic fetching child nodes is correct.
