# Logic Help

Hi Experts

I have some transaction data consecutive and I need to find out which rows consitute the total sum. Below the example:

ID     Total     Transaction     Counter
1     20          3                    1

1     20          7                    2

1     20          5                    3

1     20          5                    4

1     20          8                    5

1     20          1                    6

2     30          10                    1

2     30          10                    2

2     30          12                    3

2     30          8                    4

2     30          2                    5

I need to output the transactions which adds to the total sum. Consider the data is sorted by date and I would only need the most recent. My output should be below:

ID     Total     Transactions     Counter

1     20          3                    1

1     20          7                    2

1     20          5                    3

1     20          5                    4

2     30          10                    2

2     30          12                    3

2     30          8                    4

Transactions would be consecutive only, but range has to be decided based on the calculation. Can you please help me with the hints or solution.

Thanks

## Re: Logic Help

Sounds like you try to reverse engineer some report data? Perhaps you could get back to the source to get an id of the total calculation?

I don't see a date column, but you might refer to Counter? And how do you mean by recent in this case, you example seems to show the opposite...?

But given your desired output, just use a sum variable, together with a first. logic and explicit output (all in the data step).
