Answer / kuni_ankita

Take one variable $$var
in exp trans take one variable port and assign set variable($$var,$$var+1)
then take one router transformation with three group
mod($$var,3)=1 to one tgt
mod($$var,3)=2 to next tgt
mod($$var,3)=0 to another tgt
SD-SQ-EXP-ROUTER-TD1 TD2 TD3

Answer / sg

SQ-Exp-Rou-Tg1 TG2 Tg3

Exp transformation: for generating sequence number ( u can use sequence generator setting max value to 3)

o_count = iff(o_count=0 or o_count=4,1,o_count+1)

Router group condition,
O_cout=1, TG1
O_cout=2, TG2
O_cout=3, TG3

Answer / kamleshmishra291

Take a mapping variable of count type $$INCR=1
After SQ take expression and add a variable port
v_INCR_VARIABLE= IIF($$INCR=3,SETVARIABLE($$INCR,0)+1)
Take router and add three groups
Group1-> $$INCR=1
Group2-> $$INCR=2
Group3-> $$INCR=3
Add groups to respective targets.

Answer / ganesh kamble

We can clearly understand that we need a Router transformation to route or filter source data to the three target tables. Now the question is what will be the filter conditions.

First of all we need an Expression Transformation where we have all the source table columns and along with that we have another i/o port say seq_num, which gets sequence numbers for each source row from the port NEXTVAL of a Sequence Generator start value 0 and increment by 1.

Now the filter condition for the three router groups will be:
MOD(SEQ_NUM,3)=1 connected to 1st target table MOD(SEQ_NUM,3)=2 connected to 2nd target table MOD(SEQ_NUM,3)=0 connected to 3rd target table

how to get the first row without using rank t/r?

to improve the performance of aggregator we use sorted input option and use sorter t/r befor aggregator. But here we are increasing one more cache in our mapping i.e; sorter. So how can u convince that you are increasing the performance.?

CANNOT USE PARAMETER FILE! Hi all, I am trying to use parameter file for my workflow. This could help me to filter records where CITY = 'Portland' Following is what I have done: **in Designer - create new parameter : $$PARA_FIL, Parameter, String, IsExprVar=TRUE, Initial value = [empty] - Source Qualifier/ Properties/Source Filter: CUSTOMERS.CITY='$$PARA_FIL' **Create Parameter file: C:\Informatica\PowerCenter8.6.0 \server\infa_shared\BWParam\DynamicParamTest.txt $$PARA_FIL='Portland' **Configure workflow to use the parameter file: Edit Workflow/Properties/Parameter Filename: C:\Informatica\PowerCenter8.6.0 \server\infa_shared\BWParam\DynamicParamTest.txt I also configured directory of parameter file for session task. However, I just got this in the session log: [SQ_CUSTOMERS] SQL Query [SELECT CUSTOMERS.CUSTOMER_ID FROM CUSTOMERS WHERE CUSTOMERS.CITY='$$PARA_FIL'] No record has been loaded to target. It seems that the parameter file has not been read. I cannot understand the reason why. Could any of you kindly suggest me anything? Thanks

Suppose we have a csv file with contents as below which is used has a source file. C1,C2,C3,C4 100,200,A B,300 200,400,X,Y,299 ---> it should be 4 values but by mistake 300,600,C D,566 with a comma in between X & Y,its 5. My target takes only 4 columns, How to take care of the 2 record as above without rejecting it and loading in the target. Hope u guys have understood my scenerio
