Hi Ramesh,
We can very well restrict the data in Data Services.
In First case ,if we have any such field as Sequence number or Serial number ,you can very well take two query transform and put a condition under Where TAB that "Serial Number" >= 2,50,000 and "Serial Number" <=4,50,000. and in the other transform ,Where condition as "Serial Number"<2,50,000 or "Serial Number" >4,50,000.
In Second Case,if there is no such input field as Serial Number,we can define a field as "Gen_S_no" in Target where in the input mapping you can write "gen_row_num();" . This function would generate a field with value of serial number or each row,starting from 1 to the total number of rows.
And again you can use the approach described in the First option of using where TAB with "Gen_S_no" >=2,50,000 and "Gen_S_no" <=4,50,000. and in the other transform ,Where condition as "Gen_S_no" <2,50,000 or "Gen_S_no" >4,50,000.
Hope this would be helpful to you.
Please let us know if you face any issues.
