SF Integration Issues

Hi All,

My scenario is SF - SAP PO- SFTP.I have all the necessary authorizations for the SF user.

I am trying to select an active user from SF  using the below query -

SELECT person, employment_information, job_information FROM CompoundEmployee where person_id_external = '1048' .

I am getting the below error  . Screen shot for 1st Query (SFqueryissue1)

When i changed the query to SELECT person, employment_information, job_information FROM CompoundEmployee where person_id = '1048'

I am getting No data returned . Screen shot for 2nd Query(Query2).

I am attaching the screen shot of SF for the active user 

Need experts advise on the below issue  .

Regards

Sharath
