  • Strong,

    Which version of CCS are you using? Are you using SysConfig to configure the project build and launch SFRA?

    Can you confirm that the Save SFRA Data as CSV box is checked?

    The SFRAData directory is expected to have the same base level as the RELEASE directory.

  • CCS10.1,  yes, the option is check for saving the SFRA data.

  • Strong,

    Can you open the Kit.json file in your project and let me know what the SFRAdata path variable is at the end of the file. 

    Additionally,  can you check and see if the file is located within the SFRA library or powerSUITE utility directory. In the past, I've seen the files get generated in these directories.

    there is no SFRAData file in the project folder:

    I search the file in the below folder, still did not find the file generated recently.

  • Strong,

    Can you try using a new Workspace?
