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.

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
