I have one source table and three target tables.
When the session runs for the first time involving the
mapping,i want that the loading should take place in 1st
Target table only.
The 2nd time the same session runs the loading should take
place in 2nd Target only only
and similarly when the session runs for the 3rd time loading
should take place in Third only.
And again when the session runs for the 4th time loading
should take place in 1st Target table.

We can achieve this by using Mapping Variable and Mod function.
Create a mapping var. and using the SetVariable() fun increment its value by 1 every time when the session runs succesfully.
And in the Router create 3 groups and give the conditions, Mod($$var,3)=0,Mod($$var,3)=1,Mod($$var,3)=2.
And map each group of Router to 3 different Targets.

Answer / vineet katyal
take mapping variable $$count-to count the number of session runs(initial value as 1 and default value as 1)
from source take the input to expression transformation and add two variable ports
V_flag=DECODE(MOD($$COUNT,3,1'FIRST',2,'SECOND',0'THIRD')
V_count=SET VARIABLE($$COUNT,$$COUNT+1)
now router transformation
three user defined groups
v_flag=first
v_flag=second
v_flag=third
now add three groups to three targets.
after every successful session run the mapping variable value gets updated by 1 in the repository.
first time the variable value will be 1 as SET VARIABLE WILL BE PROCESSED AFTER FLAG VARIABLE PORT

Create a mapping variable $$INCR=1
Take Expression Transformation after SQ
In Expression Transformation create a variable port:
v_count_session=IIF($$INCR=4,setVariable($$INCR,1),setVarialbe($$INCR,$$INCR+1))
After Exp take a ROUTER Transformation and create three groups with conditions :
GROUP1
$$INCR=1
GROUP2
$$INCR=2
GROUP3
$$INCR=3
Finally connect groups to group1--tgt1, group2--tgt2, group3=tgt3

Hi all,
Use sequence generator to generate the sequence.
properties should be
start value=1
end value=3
check the cycle option.
connect this nextvalue port to router and make there groups.
group_1----> nextvalue=1
group_2----> nextvalue=2
group_3----> nextvalue=3
connect first group to first target and second group to second target and then third to third.
flow will be like this
sequence generator
|
source---->source qualifier---->router--------Target 1
|-----------Target 2
|-----------Target 3
