Can you please help this query. As follows:

Actual scenario: We have two methods to pull up the data from MS SQL Server to BW Server using DB Connect.

1st Method is directly from MSSQL server to BW server.

2nd Method is MSSQL -> Temporary files -> Flat files -> BW server.

Here for easy process and performance we use 1st Option.

So my question is Our client is asking for comparision of both methods and advantages & disadvantages. Process for 1st Option.

Its urgent ...plz help me out..

    In the first method, data extraction is direct on the BW Targets & hence less maintenance work.Data in targets can be dropped & pulled any time.Data mismatch issue is very minimal.

    In the second method,data from the MSSQL server has to be converted into Temporary Files.Manual effort is required, in case data is loaded from Presentation Server else path to be configured(using tcode FILE) in application server. If historical data has to be pulled,there is manual dependency to populate the temporary file & then have it loaded into BW.
