lookup transformation in ssis

Hi,

I have one below requirement in ssis i need to develop the package.

Customer TblStaging Table             Detail  

(Source Srvr)             

-----------------------------------           ------------------

CustomerIDCustID                      CustID

NameStaffID                      Name

In the above staging table, CustID and StaffId will have some similar values as in CustomerID coln in  CustomerTable(Source Srvr).

To check the customerid is same in the staging table custid then i need to pick the customerid and its name to destination table.

Customer:            Staging Table  Detail Table

1. CustomerID -----> CustID ------------> CustID and Name

& Name

To check the customerid is same in the staging table staffid then i need to pick the relevant customer id and its name to destination table.

2. CustomerID------->Staffid---------------> CustID and Name

& Name

I have used the below logic,

1.  Oledb source

select Customerid,Name from customer

2.Lookup

Select custid,staffid from Staging

In columns, matching customerid with custid only

fetching only Matching records

3. Lookup

Select custid,staffid from Staging

In columns, matching staffid with custid only

fetching only Matching records

4.Oledb Destination

Mapping customerid and full name

Please suggest me if i did anything wrong or tell me any better way to do it.

Thanks,

Lucky
