How to load historic data for the new field between DSO to DSO

Hi All,

I have a requirement to load the data between DSO to DSO for the new field.

The field is available in both DSO's but the dataload is not happening for that field.

I have to map the field and need to load the historic data for that field only.

Please guide me the steps to complete the historic data laod.

Thanks,

Phani
