• What is the cause and solution for SAP error message /FTI/WEBGUI_MSG098 - The subobject of the complex app does not have a unique filename ?

  The SAP error message /FTI/WEBGUI_MSG098 indicates that there is an issue with the configuration of a complex application in the SAP system, specifically related to the uniqueness of filenames for subobjects. This error typically arises in the context of SAP Fiori or Web GUI applications where multiple components or subobjects are involved.
  Cause:
  The error is caused by the following factors:
  
  Non-Unique Filenames: The subobjects of the complex application are not assigned unique filenames. This can happen if multiple components or views are trying to use the same filename, leading to conflicts.
  Configuration Issues: There may be misconfigurations in the application setup or in the transport requests that are causing the system to not recognize the unique identifiers for the subobjects.
  Development Errors: If custom developments or modifications have been made to the application, they may not adhere to the required naming conventions or uniqueness constraints.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Subobject Filenames:
  
  Review the filenames of the subobjects in the application. Ensure that each subobject has a unique filename. This may involve renaming files or adjusting the configuration to ensure uniqueness.
  
  
  
  Review Application Configuration:
  
  Go through the configuration settings of the complex application. Ensure that all components are correctly defined and that there are no duplicate entries.
  
  
  
  Transport Requests:
  
  If the issue arose after a transport, check the transport requests to ensure that they were correctly imported and that there are no conflicts with existing objects.
  
  
  
  Debugging:
  
  If you have access to the development environment, you can debug the application to identify where the error is being triggered. This may provide insights into which subobject is causing the conflict.
