Where Is The Problem with link server query?

I have a table like:
In my server

CREATE TABLE dbo.[tbl_C09_SMSC_To_PSA] (
            [Entry_Date] [smalldatetime] NULL ,
            [Usage_Date] [smalldatetime] NULL ,
            [Process_Date] [smalldatetime] NULL ,
            [Source_System] [char] (4) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [Total_Event] [bigint] NULL
) ON [PRIMARY]

GO

And

CREATE TABLE [PSA20040919] (
            [ENTRY_DATE] [smalldatetime] NULL ,
            [FILE_NAME] [char] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [RECTYPE] [char] (5) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [A_NUMBER] [char] (15) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [B_NUMBER] [char] (30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [PSA_DATE] [char] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [PSA_TIME] [char] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [TARIFF_PLAN] [char] (5) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [CURRENCY_SIGN] [char] (5) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [CHARGED_AMOUNT] [float] NULL ,
            [REMAINING_BALANCE] [float] NULL ,
            [OPERATION] [char] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
            [DATE_USAGE] [smalldatetime] NULL
) ON [PRIMARY]

 

in the server gpra740
now I would like to do following Query on my server :

insert into dbo.tbl_C09_SMSC_To_PSA

(entry_date,usage_date,process_date,source_system,total_event)
select '2004-09-01' as a ,date_usage,'20040901' as b ,'PSA' as c,count(*)  as d
from gpra740.psadb.dbo. PSA20040919 where charged_amount=-2.3
group by date_usage

 
But it generates Following Error:

Server: Msg 7341, Level 16, State 2, Line 1
Could not get the current row value of column '(user generated expression).Expr1003' from the OLE DB provider 'SQLOLEDB'. Could not convert the data value due to reasons other than sign mismatch or overflow.

[OLE/DB provider returned message: Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.]

OLE DB error trace [OLE/DB Provider 'SQLOLEDB' IRowset::GetData returned 0x80040e21:  Data status returned from the provider: [COLUMN_NAME=Expr1003 STATUS=DBSTATUS_E_CANTCONVERTVALUE]].

 

 But if the PSA20040919 table is in my server

Like
    insert into dbo.tbl_C09_SMSC_To_PSA
(entry_date,usage_date,process_date,source_system,total_event)
select '2004-09-01' as a ,date_usage,'20040901' as b ,'PSA' as c,count(*)  as d
from dbo. PSA20040919 where charged_amount=-2.3
group by date_usage

  then runs smoothly, then what the problem with my previous query?

 Then another interesting things ! if I create a dummy  function then it also runs  
Like:

CREATE FUNCTION DBo.Fx_dummy (@mstring varchar(50))
RETURNs varchar(50)
--AS
BEGIN
     RETURN @mstring
END

 
insert into dbo.tbl_C09_SMSC_To_PSA
(entry_date,usage_date,process_date,source_system,total_event)
select dbo.Fx_dummy('20040901') as a ,date_usage,dbo.Fx_dummy('20040901')  as b ,dbo.Fx_dummy('PSA')as c,count(*)  as d
from gpra740.psadb.dbo.psa20040831 where charged_amount=-2.3
group by date_usage

Then What is the problem…..?
Can you help me on that ……

Thanks in advance

I don't know why the remote server is mesing up the datatypes for SQL to be able to implicitly convert your dates but a solution without the functions might be;

insert into dbo.tbl_C09_SMSC_To_PSA
(entry_date,usage_date,process_date,source_system,total_event)
select '2004-09-01' as a ,date_usage,'20040901' as b ,'PSA' as c, d
from
(
select date_usage, count(*)  as d
from gpra740.psadb.dbo. PSA20040919 where charged_amount=-2.3
group by date_usage
) x
