How To Fix SWDP_WB_TOOL240 - The recursion node &1 has not a node to be repeated

SAP Error Message - Details

• Message type: E = Error

• Message class: SWDP_WB_TOOL - Web Dynpro: Messages for Workbench Tools

• Message number: 240

• Message text: The recursion node &1 has not a node to be repeated

What causes this issue?

No recurrence node is assigned to the recursion node &V1&. Without this
assignment, the definition of the recursion node is invalid.

System Response

Error message from syntax check.

How to fix this error?

Assign a recurrence node. If there is no node suitable as a recurrence
node, delete the recursion node.

Procedure for System Administrators

• What is the cause and solution for SAP error message SWDP_WB_TOOL240 - The recursion node &1 has not a node to be repeated ?

  The SAP error message SWDP_WB_TOOL240 indicates that there is an issue with the configuration of a Web Dynpro application, specifically related to the recursion node in the context of the Web Dynpro component. This error typically arises when a recursion node is defined in the context of a Web Dynpro component, but it does not have a corresponding node that can be repeated.
  Cause:
  
  Incorrect Configuration: The recursion node is defined in the context but lacks a proper structure or a corresponding node that can be repeated. This can happen if the data model is not set up correctly.
  Missing Data Binding: The recursion node may not be bound to a data source that allows for repeated entries, leading to the error.
  Modeling Errors: There may be errors in the way the data model is designed, such as missing associations or incorrect cardinality settings.
  
  Solution:
  
  
  Check the Context Node Configuration:
  
  Open the Web Dynpro component in the Web Dynpro Workbench.
  Navigate to the context of the component and verify the configuration of the recursion node.
  Ensure that the recursion node has a corresponding node that can be repeated.
  
  
  
  Define a Repeating Node:
  
  If the recursion node is intended to repeat, ensure that you have defined a node that can be repeated in the context.
  This can be done by creating a new node in the context and setting its cardinality to allow for multiple entries.
  
  
  
  Review Data Binding:
  
  Check the data binding of the recursion node to ensure it is correctly linked to a data source that supports multiple entries.
  Make sure that the data model is correctly set up to allow for the expected data flow.
  
  
  
  Test the Application:
  
  After making the necessary changes, test the application to ensure that the error is resolved and that the recursion node behaves as expected.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration, refer to the SAP documentation for Web Dynpro and context modeling for further guidance.

  Web Dynpro: A SAP technology for developing web applications that are based on the MVC (Model-View-Controller) design pattern.
  Context Nodes: In Web Dynpro, context nodes are used to define the data structure that the application will use. They can be single or repeating nodes.
  Recursion Nodes: These are special types of context nodes that allow for hierarchical data representation, where a node can reference itself.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with a developer experienced in Web Dynpro for further assistance.
