SQL Job Failing but not the stored procedure

EDIT 4/18: I want to thank everyone who has answered so far. As a test I have set up a new job which has just one step in it,

EXECUTE p_CallLog_GetAbandonedCallsForCallList

This procedure itself runs just fine and reports no errors or warnings but will not run when executed as part of a job. The error I receive when running the job is:

Executed as user: NT AUTHORITY\SYSTEM. OLE DB provider 'SQLOLEDB' reported an error. [SQLSTATE 42000] (Error 7399)   [SQLSTATE 01000] (Error 7312)  OLE DB error trace 
[OLE/DB Provider 'SQLOLEDB' IDBInitialize::Initialize returned 0x80004005:   ]. 
[SQLSTATE 01000] (Error 7300).  The step failed.

I have tried changing the run as user selection and every other selection I try results in an error of:

Executed as user: Db2WebCal. Remote access not allowed for Windows NT user activated 
by SETUSER. [SQLSTATE 42000] (Error 7410).  The step failed.

All of the users I have tried do have a local login setup on the linked server.

ORIGINAL: I have the following stored procedure that is used to fill a table with values.

PROCEDURE [dbo].[p_OutboundCallList_Create] 

AS

BEGIN

  TRUNCATE TABLE T_OutboundCallList

  EXECUTE p_LeadVendor_GetCallsForCallList  
  EXECUTE p_CallCampaign_GetCallsForCallList    
  EXECUTE p_CallLog_GetAbandonedCallsForCallList    
  EXECUTE p_NoSaleFollowUp_GetCallsForCallList

END

Running this works fine and the table is filled. After creating a job and adding the following step:

EXEC p_OutboundCallList_Create

The job fails with the following error message:

Executed as user: NT AUTHORITY\SYSTEM. Warning: Null value is eliminated 
by an aggregate or other SET operation. [SQLSTATE 01003] (Message 8153)  
Warning: Null value is eliminated by an aggregate or other SET operation. 
[SQLSTATE 01003] (Message 8153)  OLE DB provider 'SQLOLEDB' reported an error.

[OLE/DB Provider 'SQLOLEDB' IDBInitialize::Initialize returned 0x80004005:   ]. 
[SQLSTATE 01000] (Error 7300).  The step failed.

If I comment out the line

EXECUTE p_CallLog_GetAbandonedCallsForCallList

..the job runs fine. This stored procedure (p_CallLog_GetAbandonedCallsForCallList) does rely on a linked server and runs fine by itself and also runs fine when I run p_OutboundCallList_Create. It only fails when I run it as part of a job. I have tried running as a different user (sa, benderle, etc.) and always get the same result (failed).

"Null value is eliminated by an aggregate or other SET operation" is a SQL Server warning, which means you won't see it in the output if you run your query and this warning is raised (switch to the "Messages" tab in SQL Server Management Studio to see this).

Although it's a warning, presumably any warnings in a SQL job cause the job to error out. Fix the p_CallLog_GetAbandonedCallsForCallList procedure so it doesn't raise that warning and you job will work as expected.
