SWDP_WB_TOOL704
- Inconsistency: &1 has ext. mapping to &2, but is not an input element ?The SAP error message SWDP_WB_TOOL704 indicates an inconsistency in the Web Dynpro application where there is an external mapping defined for a certain element, but that element is not recognized as an input element. This can occur during the development of Web Dynpro applications when the configuration of the data model does not align with the expected input/output mappings.
Cause:

- The element being incorrectly defined in the context.
- The element not being marked as an input element in the Web Dynpro component.
- Changes made to the context or data model that were not properly reflected in the external mapping.
Model Changes: If the underlying data model has been modified (e.g., adding or removing attributes) without updating the external mapping, this inconsistency can occur.

- Check for any inconsistencies in the data model and correct them.
Rebuild the Component:
