we have 20 records in source system, when we run for the 1st time, it should load only 10 records ..

Answer / suresh

SQ ==> select rownum as num,col1,col2,.. from table
FLT ==> num >= MVar1 and num <=MVar2

Mvar1 and MVar2 are assigned with the value of 1 and 10 respectively

in EXP=>V-port - setvariable(mvar1, 10)
V-port - setvariable(mvar1, 20)

after the execution of the mapping 10 and 20 values are stored in the mvar1 and mvar2 into the repository

Answer / santosh

1. Create a mapping variable $$SESSION.
2. Link from SQ to Router t/r.
3. Create two group
a. SETMAXVARIABLE($$SESSION,$$SESSION+1) % 2 = 1
b. SETMAXVARIABLE($$SESSION,$$SESSION+1) % 2 = 0
4. Link both group to two filter and create two Sequence geneter and check the reset option.
5. Link the sequence generator to filter t/r.
6. Keep the condition as "NEXTVAL<=10" for first filter.
7. Keep the condition as "NEXTVAL>10" for second filter.
8. Link the two filter to two different target instance.

Let me know if any things wrong.
