I’ve 6 documents in 1 document list, now i want to extract particular documents from tht document list
ex:
Input:doc(0),doc(1),doc(2),doc(3),doc(4),doc(5)

Output:doc(2),doc(4),doc(5)

Pls suggest me

Is there any condition based on which you want to extract ?
If yes then apply that condition and create a separate document list .

Shruti,
If it is a static content, and you always want to extract (2), (4) & (5), in the map step, draw a transition from document list to a field(s), highlight the link and in the properties mention the array index. If (2), (4) & (5) are determined in run time, use pipeline variables and substitute them instead of providing actual value in array index.
