How To Fix SWDP_WB_TOOL264 - Node &1 (Child &3): Inconsistency in mapping to &2

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 264

• Message text: Node &1 (Child &3): Inconsistency in mapping to &2

What causes this issue?

Node &V1& is mapped to &V2&. The mapping is not consistent, however. The
subtree of &V1& is not contained completely in the subtree of &V2& and
the two subtrees do not match. "Included completely" means that each
element in the subtree of &V1& is included at the same hierarchical
level in the subtree of &V2&.
Changes may have been made to the subtree of &V2& (by changing or
deleting nodes or attributes). The first difference was established in
the child element &V3& of node &V1&.

System Response

Error message for the syntax analysis.

How to fix this error?

Update the mapping or delete it. To do this, use the relevant context
menu functions for node &V1&.
Alternatively, you can also delete individual elements of the &V1&
subtree.

• What is the cause and solution for SAP error message SWDP_WB_TOOL264 - Node &1 (Child &3): Inconsistency in mapping to &2 ?

  The SAP error message SWDP_WB_TOOL264 typically indicates an inconsistency in the mapping of nodes in a Web Dynpro application. This error can occur during the development or runtime of a Web Dynpro application when there is a mismatch or inconsistency in the data model or the configuration of the application.
  Cause:
  
  Inconsistent Mapping: The error suggests that there is an inconsistency in the mapping of a child node to its parent node. This could be due to changes made to the data model that have not been reflected in the Web Dynpro configuration.
  Model Changes: If the underlying data model (e.g., context nodes) has been modified (e.g., adding or removing attributes, changing data types) without updating the corresponding Web Dynpro components, this can lead to inconsistencies.
  Incorrect Configuration: The configuration of the Web Dynpro components may not align with the expected structure of the data model, leading to mapping issues.
  
  Solution:
  
  Check Data Model: Review the data model and ensure that all nodes and their mappings are correctly defined. Make sure that the child nodes are properly linked to their parent nodes.
  Update Web Dynpro Configuration: If there have been changes to the data model, update the Web Dynpro application configuration to reflect these changes. This may involve adjusting the context nodes, attributes, and their mappings.
  Rebuild the Application: Sometimes, rebuilding the Web Dynpro application can help resolve inconsistencies. This can be done by regenerating the application or reactivating the components.
  Debugging: Use the debugging tools available in the SAP environment to trace the execution and identify where the inconsistency arises. This can help pinpoint the exact location of the issue.
  Check for Transport Issues: If the application has been transported from one system to another, ensure that all relevant objects and dependencies have been transported correctly.
  
  Related Information:
  
  Web Dynpro Documentation: Refer to the official SAP documentation for Web Dynpro for detailed information on context nodes, data binding, and application configuration.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Community Forums: Engage with the SAP community forums or SAP Community Network (SCN) for insights from other developers who may have encountered similar issues.
  
  By following these steps, you should be able to identify and resolve the inconsistency that is causing the SWDP_WB_TOOL264 error in your Web Dynpro application.
