Transform mapping - Load data - to load only newly added comments instead of whole thread, duplicate

[maneesh3]

Hi Team,

I am using Load data module to load records into Case table using excel sheet. For, additional comments it is always copying whole thread each and every time, and making data look more. Can it be possible to only copy newly added comments instead of adding always thread . Please help!

Thanks for support
