Hi,
I have one flatfile as target in a mapping . When i am
trying to load data second time into it.
The records already is in flatfile is getting override. I
don't want to override existing records.
Note : we can do this by implementing CDC / Incremental pool
logic if target is relational .
But this is flatfile. So, even i use this same technique it
will override only
So what is the solution ?
Is there any option at session level for flatfile target ?
Advance Thanks

It's very Simple We have one option at session level.
Double click on session-->Mapping tab-->>Target properties--
>Append if exists(check this option).
