First and foremost thing, put the following data in a text file.

00122001550056200568
00256002360014500896
00123004560078900258
00147004560025800256

Follow the steps:

Take following 3 stages:

1. Sequential File
2. Transformer
3. Dataset/Sequential File

STAGE 1:

1. Sequential File Properties

Source-->File = browse & select the text file containing the
above data.
Read Method = Specific File(s)

Go to Columns Tab:
Give column name (any name), SQL Type = Varchar, length = 50
(Make sure you take the minimum length as 20 since the
character length in the input file is 20).

Now, click on the "Load" option at the bottom and import the
table definitions by choosing "Sequential File Definitions".
After the table definitions are imported. Double click on
the imported table definition. Click OK.

STAGE 2:

Transformer Properties:

Click on the O/p column, and create 4 Columns at the bottom.

Column Name SQL Type Length
Field1 Varchar 50
Field2 Varchar 50
Field3 Varchar 50
Field4 Varchar 50

Create 4 Stage variables:

Derivation Stage
Variable
Left(inputcolumnname,5) F1
Right(Left(inputcolumnname,10),5) F2
Right(Left(inputcolumnname,15),5) F3
Right(inputcolumnname,5) F4

Map the above stage variables by dragging and dropping into
the below O/p table

O/p Table

Derivation Column Name
F1 Field1
F2 Field2
F3 Field3
F4 Feild4

STAGE 3:

Dataset File Stage/Sequential File Stage Properties:

Double click and File = browse the output file path.

If it's sequential, .txt || Dataset File, .ds


Hope this helps you !!! If you follow the above procedure,
you must get the out put correct!!!

All The Best !!!

Field1: SourceColumn[1,5]
Field2: SourceColumn[6,10]
Field3: SourceColumn[11,15]
Field4: SourceColumn[16,20] use this one u will get correct o/p.

Answer / anat

Hi as per my knowledge pls follow the below steps
1)take entire source as single colom
2)in transfomer split that colom in to multiple coloms by
using substring or field functons

Answer / sindhu

BY using sequential file in format delimeter =none while importing the data enable the option fixed width and give column width 5 space 5 space 5.datatype as varchar inorder to get zeros also in output.
reducing the stages will always increase performance
