Hello @Madhan_cog1 ,
I suspect that you, whomever created the initial plan file, or as per request to SAS Technical Support/Professional Services, the plan file has to be updated to include SAS Platform Web Services, as it needs to be installed (binaries) but also configured.
Once you have the new plan file, you should be able to install the new binaries and update the configuration, by the usual means plus the indications described in the document you got on your hands.
Best regards,
Juan
