Linked server SP call from another SP

Hi Sir,
I want to call one linked server stored procedure from another stored procedure.
--BATCH FOR LINKED SERVER SETUP
SET @IBatchNum = 2

EXEC PR_Linked_Server
@VServer = 'Linked_Amisys'
,@VSrvProduct = ''
,@VProvider = 'SQLOLEDB'
,@VDataSrc = 'DTCORPMXDV9'
,@VCatalog = 'pubs'
,@VCurrentUsr = 'CORPajohri'
,@VServerUsr = 'dba'
,@VServerPwd = 'dba'
END TRY
The linked server was not created When I executed the query. However, I was able to create the linked server when I executed this query(batch 2) alone.
Is there any limitation of SP which I am not aware of?
--Sheetal

the user should have access to this SP. please check because manually you have to give access to desire object

USE MASTER
GO
EXEC master.dbo.sp_addlinkedserver
@server = 'Linked_Amisys', --This is an ODBC connection that is setup on the machine.
@srvproduct = '',
@provider = 'SQLNCLI',
@datasrc = 'Linked_Amisys',
@catalog = 'database_name'
go
EXEC master.dbo.sp_addlinkedsrvlogin
@rmtsrvname=N'Linked_Amisys',
@useself=N'False',
@locallogin=NULL,
@rmtuser=N'dba',
@rmtpassword='dba'

go
then call the stored procedure using
Method 1 : Remote Stored Procedure can be called as four part name:
Syntax: EXEC [RemoteServer] .DatabaseName.DatabaseOwner.StoredProcedureName ‘Params’
Example: EXEC [DEVSQL] .AdventureWorks.dbo.uspGetEmployeeManagers ‘42′

Method 2 : Use Distributed Query functions (OpenQuery())
Syntax: SELECT * FROM OPENQUERY([RemoteServer],DatabaseName.DatabaseOwner.StoredProcedureName)
Example: SELECT * FROM OPENQUERY([DEVSQL],AdventureWorks.dbo.spAdmin_GetAllUsers)
