How To Fix SWDP_WB_TOOL228 - The recursion node cannot be an attribute

SWDP_WB_TOOL228 - Overview

• Message type: E = Error

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

• Message number: 228

• Message text: The recursion node cannot be an attribute

What causes this issue?

You are processing a recursion node to which, so far, no recurrence node
has been assigned. Or you wish to change the assignment and assign an
attribute.

System Response

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

How to fix this error?

A recursion node is only defined in valid form if it has the node that
is to be recurrent assigned to it. This node must be on the path of the
root node to the recursion node - that is, either directly or indirectly
predecessor. Therefore, an attribute cannot be used as a recurrence
node.

SWDP_WB_TOOL228 - Details

• The SAP error message SWDP_WB_TOOL228, which states "The recursion node cannot be an attribute," typically occurs in the context of SAP Web Dynpro development when you are trying to define a recursive relationship in a data model or component that is not allowed.
  
  Cause:
  This error arises when you attempt to define a node in a Web Dynpro component that references itself as an attribute. In other words, you are trying to create a recursive structure where a node is defined in such a way that it points back to itself, which is not permitted in the context of Web Dynpro.
  
  Solution:
  To resolve this error, you should:
  
  
  Review the Data Model: Check the structure of your data model. Ensure that you are not trying to define a node that references itself directly as an attribute.
  
  
  Use a Different Structure: If you need to represent a hierarchical or recursive relationship, consider using a different approach. For
