How to increment the counter (variable) based on the incoming data in snaplogic

Thank you So much sarathmattam,

I’m able to achieve this using mapper in the following way.

1. Read the data in sorted order

2. Generate the sequence

3. Copy the data into two outputs

4. For one o/p, Use Aggregate to find the min sequence grouping on the cost_center

5. From other o/p join the data using the cost_center

6. Use Mapper, and in one of the port define the logic as : (Value - min_Seq)+1

   Here Value is the sequence generated from the sequence snap

   Min_Seq is the minimum sequence value of the respective group obtained from aggregate snap.
