How To Fix SWDP_WB_TOOL229 - Recursion node and node to be repeated cannot be identical

SWDP_WB_TOOL229 - Overview

• Message type: E = Error

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

• Message number: 229

• Message text: Recursion node and node to be repeated cannot be identical

What causes this issue?

A recursion node is only defined in a valid way if a node that is
recurrent is assigned to it. This node must be on the path from the root
node to the recursion node - that is, it must be its direct or indirect
predecessor.
Recursion nodes and recurrent nodes cannot be together.

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 SWDP_WB_TOOL229 - Recursion node and node to be repeated cannot be identical ?

  The SAP error message SWDP_WB_TOOL229 indicates that there is a problem with the configuration of a Web Dynpro application, specifically related to the use of recursion in the node definitions of the data model. This error occurs when a node is set to be recursive, but the node that is supposed to be repeated is the same as the recursion node, which is not allowed.
  
  Cause:
  The error arises from the following conditions:
  
  Recursion Definition: In a Web Dynpro application, a node can be defined to be recursive, meaning it can reference itself in a hierarchical structure.
  Node Configuration: If the node that is defined to be recursive is also set as the node to be repeated (i.e., the node that is used to display multiple instances of itself), it creates a conflict. The system cannot process this configuration because it leads to an infinite loop or ambiguity in the data structure.
