SAP BODS Default value comes in Date field

Hi Experts,

I am Working on SAP BODS.

Data Service version is 4.0 patch 3.0.

My Source system is SAP ECC and target system is MS SQL.

Now in SAP ECC I have tables in which 2 date fields are there.

Now in data services I have used ABAP Data flow.

Now when I transform my tables to data services there are some rows in tables which has that 2 date fields are blank so now that blank fields are transform to date as "1900.01.01"

I want that fields as blank.

Please suggest me if any idea.

Thanks in advance,

With Regards,
