Answer / siva

Import the file with comma delimited, so that, it creates
with 5 columns c1,c2,c3,c4,c5
take the mapping as follows:
SQ --> Exp -->filter--> target_
in the expression take a variable port and assign the value
as iif(c1 = 1,concatenate all the c2,c3,c4,c5 otherwise
concatenate varibale post value with c2,c3,c4,c5)
then you will get as follows:
c1, v_p
1, 'x1,x2,x3,<null>'
2, 'x1,x2,x3,<null>,a1,a2,<null>,<null>'
3, 'x1,x2,x3,<null>,a1,a2,<null>,<null>,b1,b2,b3,b4'
1, 'y1,y2,y3,<null>
2, 'y1,y2,y3,<null>,c1,c2,c3,<null>
3, 'y1,y2,y3,<null>,c1,c2,c3,<null>,d1,d2,<null>,<null>'

you can lso ingnore the unncessary columns where ever

filter out only c1 = 3 to the target

It helps you to succeed..
