FSM Scheduling Manager erroring out when initializing dataset

Hi Team,

I am trying to run the PSO dataset initializing from Scheduling Manager screen in PSO but could see the below error:
“The given URI must be absolute.
  Parameter name: uri”
Even the load job is not running and the rota data sync is not happening from FSM to PSO when I manually called the relevant MPM from the XML poster. The transaction is completed in XML Poster but no data in threesixty_ram_load_history table.
Rota:
<perform_send_rota_data_to_dse>
  <parameters>
    <dataset_id>FSM DEMO</dataset_id>
  </parameters>
</perform_send_rota_data_to_dse>
and Load Job:
<perform_initialize_threesixty>
  <parameters>
    <dataset_id>FSM DEMO</dataset_id>
  </parameters>
</perform_initialize_threesixty>
I tried to update the webconfig file for the FSM-PSO integration as I am trying to do a initial dataset initialization after the FSM and PSO installation to fix the below error but did not helped me.
Added below in webconfig- 
<endpoint address="https://xitfsm/IFS/Scheduling/Gateway/Service/Data" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IDataRequest" contract="GatewayService.IDataRequest" name="WSHttpBinding_IDataRequest" />

Can you please look at the correctness of the endpoint address added for the FSM-PSO integration in the webconfig file?
Also if you can help me with the error message I am getting.

Regards,
Deepak Kumar
