This one is the most complicated that i had ever seen.
Basically it is inverse pivot functionality. but in order to perform inverse pivot
functionality we need at-least 2 columns. So, i am going to generate that extra
column with "1" in 6 rows.
Then Based on this i done the concatenation, after concatenation i used copy
stage then from copy stage one link is going to remove duplicate stage and
another one to lookup stage. in remove duplicate stage i collected the retain =
last value (a,b,c,1,2,3), 1 . in lookup stage i combined both the data and used
transformer stage to collect (a,b,c) then i made a concatenate with (a,b,c) with
actual values(a,b,c,1,2,3) then the data will be {(a,b,c,a),(a,b,c,b),(a,b,c,c),(a,b,c,1),
(a,b,c,2),(a,b,c,3)} now i specified a condition so that i can collect the specified
requirement {(a,b,c,1),(a,b,c,2),(a,b,c,3)}
I can't post the screen shot's if u need further clarification Feel free to mail
mee. I will send the screen shots..
ALL THE BEST !!
KEEP POSTING...

We can do it using Transformer.Take 3 stage variables(s1,s2,s3),for s1 map the
input column and for s2 we have to write the condition like if
alpha(inputcolumn)= true then trim(s3:,:s1,,,) else s3:,:inputcolumn. for s3 also
we have to write the condition like if alpha(inputcol) true then map s2 into s3
else map s3 to s3.
Input column---->S1
if alpha(inputcolumn)=true then trim(s3:,:s1) else trim(s3:,:inputcolumn)--------
>s2
if alpha(inputcoumn)=true then s2 else s3------->s3
In constraint part we have to write the below condition
if alnum(s2)=true
In derivation part we have to map s2 to output column
I think it will work

source-->Transformer(use field function by taking stage variable like
field(inputcolumn,,,1,3) and concatenate this field value aging with field ---->
Pivot stage--->target.

Source->TR->RD->Pivot->Target,by using these order of stages we can get
required output.
Transformer:
we have to concatenate the values by using loop(we will get like a,b,c,1,2,3)
after that we have to split it into separate fields using field function.
o/p is:c1 c2 c3 c4 c5 c6 c7
1 a
1 a b
1 a b c
1 a b c 1
1 a b c 1 2
1 a b c 1 2 3
(if we dont want this dummy column we can drop it here itself)
RemoveDuplicate:
put condition retain last
o/p is: c1 c2 c3 c4 c5 c6 c7
1 a b c 1 2 3
pivot;
in derivation of c5 column give c5,c6,c7
here we are converting columns into rows
o/p is: c2 c3 c4 c5 c6 c7
a b c 1
a b c 2
a b c 3

Hi.,
we can achieve this by
source--->pivot-->Transformer --> target
we will get 6 columns from pivot stage(columns to rows) then
In transformer stage we have to concatenate the input columns
like col1:col2:col3:(here we can use stage variables and increment that value by
one)
regards
sreenu

Source we have like this a,b,c,d,e,f here 6 columns
a,b,c,1,2,3
e,f,g,4,5,6 we need to get in target
like this a,b,c,1 and a,b,c,2 and a,b,c,3 and e,f,g,4 for that we have to use just
three stages
source---------------->pivot------------------------>target
in pivot we need to implement this code
column,derivation
a,a
b,b
c,c
values,d,e,f and target file name this will work to get that result

Very simple..please go through below.
Input:
CUST_ID
----------
a,b,c,1,2,3
Output:
CUST_ID:
-------------
a,b,c,1
a,b,c,2
a,b,c,3
Solution:
We can solve it from below solution.
JOB flow: Transformer (3 ouyput links)----> Funnel---->Dataset
In Transformer: Use 3 stage variables,
in sv1: left(Cust_id,1,7)
in sv2: left(Cust_id,1,6)||Left(right(Cust_id,3),1)
in sv3: left(Cust_id,1,6)||Right(Cust_id,1)
Take 3 outputs from Transformer, map sv1 to output-1 column CUST_ID,
map sv2 to output-2 column CUST_ID,
map sv3 to output-3 column CUST_ID
Here one input record splits into 3 output records.
Now cature all three output records using Funnel stage.

Guys try simple way.
Source.....trans.....pivot...target
trans...we can use filed function and create new column
col1:filed(inputcol,,,4,1)
col2:filed(inputcol,,,5,1)
Col3:filed(inputcol,,,6,1)
And pivot put output col :col1,col2,col3
Then you can get output
