I Want to an output like this:
Overs
Total_Runs
1
10
2
25
3
39
Description: - For First Over means First 6 Balls I Want Sum of First 6 Balls that is 10. and For Second 6 Balls I Want Sum of First 6 Balls [Over] + Second 6 Balls That is 25 [10 + 15 = 25]. and For Third 6 Balls I Want Sum of First 6 Balls [Over] + Second 6 Balls + Third ^ Balls That is 39 [10 + 15 + 14 = 39].
Note: - 6 balls means one over.
How to create a mapping in for this scenario in Informatica / which logic should I use?

Answer 1

i will assume your data is EXACTLY like you have shown in your question. If its not like this in source then it will be a major issue. If its a table where data is not sorted, it will be an issue.
Solution -
Create an expression transformation with below ports - in below order. in - input port, v_variable port, out_* output port
in_balls
in_runs
in_overs
v_cumulative_runs= in_runs+ iif(isnull(v_cumulative_run),0,v_cumulative_run)
out_total_runs=v_cumulative_runs
out_overs=in_overs
Use an aggregator -
in_total_runs
in_out_overs -- group by this port
out_total_runs = max(in_total_runs)
Attach in_out_overs and out_total_runs links to target.
