Transformation involving same DSO

Hi,

I have a transformation in which DSO is mapped to the same DSO. For Ex: DSO1 -> DSO2.

Can anyone pls explain why and how does this work?

    Hi,

    This is called cyclic transformation and mainly done to populate some fields of the DSO based on some lookup values. Suppose that all the fields of a particular DSO is getting populated from the data source but some of the fields need to be populated based on the values of some other infoprovider. This can be written in the Start Routine and the corresponding field level routine of the transformation from the same DSO. The lookup table can be populated in the start routine and that table can be used in field level routine to populate that particular field

    Navesh.

    Hi,

    This is self transformation and it is used for feeding data back to same data target again.

    This can be for multiple purpose

    1. You can store the historical data

    2. In case you need to modify the data by looking up or since you can not delete data you can carry out modifications or new field population through this method.

    Thanks and regards

    This terminology is called self transformation where certain fields get updated from data present in underlying DSO. This is just to feed the data to itself. This feature can be used for various reasons.
