As you have a single text file as Source. Use folloowing
approach to get the desired output.
Head1 Target1
Seq. File Copy Tail2 Target2
Head3 Tail Target3
Steps:
1.> Read your source file using sequential file stage.
2.> Pass the records to copy stage and take 3 output link.
3.> 1 to Head stage head1, 2nd to Head2 and 3rd to Head3.
4.> In the 1st Head Stage Head1, in the properties specify
1, it will pick up the 1st record and make that record to
target 1.
5.> Similarly, to capture last record in target2, in Tail
stage property mention 1. It will take last record and pass
it to target2.
6.> To load rest records 1st using head stage, capture top
records say, if u have 10 records in the source pick top 9
records using head stage then use tail stage followed by
head stage and mention 8, it will pick all records except
1st one. then u can load these to target3.
If u get confused ask me ....
Thanks
