SWDP_WB_TOOL154 - Details

• The SAP error message SWDP_WB_TOOL154 indicates that there is a mismatch between the signature of a component interface and the implementation of that interface in the Web Dynpro application. This typically occurs when there are changes made to the interface (like adding or removing parameters) without corresponding updates to the implementation.
  
  Cause:
  
  Interface Changes: The component interface has been modified (e.g., parameters added, removed, or changed) but the implementing component has not been updated accordingly.
  Version Mismatch: The version of the component interface being used does not match the version of the implementation.
  Transport Issues: If the changes were transported from one system to another, the transport might not have included all necessary objects, leading to inconsistencies.
  
  
  Solution:
  
  Check Interface Definition: Review the component interface definition to ensure that it matches the implementation. Look for any discrepancies in the parameters.
  Update Implementation: If the interface has changed, update the implementing component to match the new interface signature.
