YTD Calculation using analytical functions Thu, 04 February 2010 03:09

Hi,

I am using Oracle Database 10gR1.

I want to calculate ytd ( year to date calculation ), then i have to sum up monthly then sum up for yearly.
Eg : I have to calculate YTD as follows :

GL Curr Day Amount Month YTD
5805 45454 1-Jan 5.23 5.23 5.23
5805 45454 2-Jan -4.52 0.71 5.94
5805 45454 3-Jan 25.3 26.01 31.95
5805 45454 4-Jan 10.53 36.54 68.49
5805 45454 5-Jan -1.88 34.66 103.15

Here in this example, we have column names as gl, curr, day, amount, month, year ; taken from a 1 transaction table.
Now, To calculate ytd (year to-date calculation), i have to calculate month first and then year.

Step 1: Month wise summation :
I have to calculate sum for each day of the month.

From above example for month wise summation:
GL Curr Day Amount Month
5805 45454 1-Jan 5.23 5.23 ( sum of jan1 = 5.23 )
5805 45454 2-Jan -4.52 0.71 ( sum of jan2 = 5.23 + (-4.52) = 0.71 )
5805 45454 3-Jan 25.3 26.01 ( sum of jan3 = 0.71 + 25.3 = 26.01 )
5805 45454 4-Jan 10.53 36.54 ( sum of jan4 = 26.01 + 10.53 = 36.54 )
5805 45454 5-Jan -1.88 34.66 ( sum of jan4 = 36.54 + (-1.88) = 34.66 )

Step 2: Year wise summation : YTD Calculation :
We have done Step1 process to calculate this Step2 process, i.e., YTD Calculation.
So, we have to do Year wise summation with the Step1 month wise data ( with the above output date ).

Again, from above example for year wise summation:
GL Curr Day Amount Month YTD
5805 45454 1-Jan 5.23 5.23 5.23 ( ytd = 5.23 )
5805 45454 2-Jan -4.52 0.71 5.94 ( ytd = 5.23 + 0.71 = 5.94)
5805 45454 3-Jan 25.3 26.01 31.95 ( ytd = 5.94 + 26.01 = 31.95 )
5805 45454 4-Jan 10.53 36.54 68.49 ( ytd = 31.95 + 36.54 = 68.49 )
5805 45454 5-Jan -1.88 34.66 103.15 ( ytd = 68.49 + 34.66 = 103.15 )

So for year to-date calculation, we have to sum all the dates for a month and then sum all the month to get ytd.
how can i do this ytd using any analytical functions (i.e., i have to sum up for every row) ?

Thanks.

With Regards,
Raja.

You've got an answer on Usenet forums where it has been asked to you to post a test case.
Same thing here: Post a working Test case: create table and insert statements along with the result you want with these data then we will work with your table and data.

Make sure that lines of code do not exceed 80 characters when you format.
Indent the code, use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version with 4 decimals.

Regards
Michel

I have tried an example.

1. is this correct for month summation alone ?
2. should i again do the same procedure to get for year summation
too ?
i.e., take the below query data ( month summation ) as input and again
form the same query for year summation ?

SELECT
A.CURR,
A.DATA_TYPE_COD,
A.GL_POST_ACCN,
A.PRDMKT_COD,
A.SCENARIO_COD,
A.ACCN_PERIOD_COD,
A.TRANS_DES,
A.CURRENCY_TRAN_COD,
A.REP_ENT_COD,
A.COST_CENTER,
B.ACCN_PERIOD_COD,
B.ACCN_YEAR,
B.CURR_ACCN_START_DT,
A.FUNC_AMNT,
SUM(A.FUNC_AMNT) MONTH
OVER
(
ORDER BY
A.CURR,
A.DATA_TYPE_COD,
A.GL_POST_ACCN,
A.PRDMKT_COD,
A.SCENARIO_COD,
A.ACCN_PERIOD_COD,
A.TRANS_DES,
A.CURRENCY_TRAN_COD,
A.REP_ENT_COD,
A.COST_CENTER,
B.ACCN_PERIOD_COD,
B.ACCN_YEAR,
B.CURR_ACCN_START_DT,
A.FUNC_AMNT
ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
) AS "YTD"
FROM
MASTER B,
TRANSACTION A
WHERE ( A.ACCN_PERIOD_COD = B.ACCN_PERIOD_COD );

I have tried an example.

1. is this correct for month summation alone ?
2. should i again do the same procedure to get for year summation
too ?
i.e., take the below query data ( month summation ) as input and again
form the same query for year summation ?

```SELECT
A.CURR,
A.DATA_TYPE_COD,
A.GL_POST_ACCN,
A.PRDMKT_COD,
A.SCENARIO_COD,
A.ACCN_PERIOD_COD,
A.TRANS_DES,
A.CURRENCY_TRAN_COD,
A.REP_ENT_COD,
A.COST_CENTER,
B.ACCN_PERIOD_COD,
B.ACCN_YEAR,
B.CURR_ACCN_START_DT,
A.FUNC_AMNT,
SUM(A.FUNC_AMNT) MONTH
OVER
(
ORDER BY
A.CURR,
A.DATA_TYPE_COD,
A.GL_POST_ACCN,
A.PRDMKT_COD,
A.SCENARIO_COD,
A.ACCN_PERIOD_COD,
A.TRANS_DES,
A.CURRENCY_TRAN_COD,
A.REP_ENT_COD,
A.COST_CENTER,
B.ACCN_PERIOD_COD,
B.ACCN_YEAR,
B.CURR_ACCN_START_DT,
A.FUNC_AMNT
ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
) AS "YTD"
FROM
MASTER B,
TRANSACTION A
WHERE ( A.ACCN_PERIOD_COD = B.ACCN_PERIOD_COD ); ```

Could you simplify the test case and post ONLY the relevant columns.
Could you tell us what is the partitioning key?
From your example it seems it is (GL, Curr) but to which table columns correspond these result columns?

Regards
Michel

Please consider that there are no indexes or partitions.

The results you posted contains only 5 or 6 columns and only 4 comes from the table (and 1 or 2 calculated) so you don't need to post a table with 14 columns).
Your results mention columns GL, Curr and Amount but you didn't say to which table columns these are related to.

When I talk about partition it is logical partition that is on what we have to group by (or partition) to sum?

Hope the confusion is rectified in this post.

I have consolidated required data in the upload file.

1. TestCase ( DDL and DML )
2. Query Used ( to get only one summation - for month wise )
3. Output got.

Help Required :
Re-writing query to get double summation - to get year wise
for every record in that table.

You didn't simplify the example.
Stop.
We don't need all columns for a test case.
Stop.
Waiting...

To simply example, here comes :
I have a table with 4 columns : col1 col2 col3 col4.
col4 is amt column.
eg : ( we have 4 rows here )
col1 col2 col3 col4
101 AB 1501 10.0
101 AB 1501 20.0
101 AB 1501 30.0
101 AB 1501 40.0

Now, i need to get the summation of col4 to calculate month and year wise summation ( so 2 summations have to be done on col4 alone, for every value of all columns ):

mtd - Monthwise ( 1st summation )
----------------------------
10.0 (col4 1st row value, itself)
30.0 (col4 1st row + 2nd row value)
60.0 (col4 1st + 2nd + 3rd row value)
100.0 (col4 1st + 2nd + 3rd + 4th row value)

So we get mtd as follows ( this is first summation ):
col1 col2 col3 col4 mtd
101 AB 1501 10.0 10.0
101 AB 1501 20.0 30.0
101 AB 1501 30.0 60.0
101 AB 1501 40.0 100.0

ytd - Yearwise ( 2nd summation )
----------------------------
10.0 (col4 1st row value, itself)
40.0 (col4 1st row + 2nd row value)
60.0 (col4 1st + 2nd + 3rd row value)
100.0 (col4 1st + 2nd + 3rd + 4th row value)

So we get ytd as follows ( this is second summation, got from 1st summation ): Here col4 is derived values of mtd calculation.
col1 col2 col3 col4 ytd
101 AB 1501 10.0 10.0
101 AB 1501 30.0 40.0
101 AB 1501 60.0 100.0
101 AB 1501 100.0 200.0

so finally we are doing summation ( like incremental summation for a column ) twice for col4 to calculate ytd, by grouping all the other columns ( like col1, col2, col3 )

Is this example fine ?

There is no date column in your table, so month wise and year wise is irrelevant and sum of sum is not the same thing has sum along months and sum along years.
And where is the script I can execute?

Just repost the previous script but with just the columns you called GL, Curr, Day and Amount in your first post.

You can do the MTD figures like this:
```with src as (select 5805 GL,  45454 curr, to_date('1-Jan-2010','dd-mon-yyyy') dy, 5.23 amount from dual union all
select 5805, 45454, to_date(' 2-Jan-2010','dd-mon-yyyy'), -4.52 from dual union all
select 5805, 45454, to_date(' 3-Jan-2010','dd-mon-yyyy'), 25.3 from dual union all
select 5805, 45454, to_date(' 4-Jan-2010','dd-mon-yyyy'), 10.53 from dual union all
select 5805, 45454, to_date(' 5-Jan-2010','dd-mon-yyyy'), -1.88 from dual)
select gl
,curr
,dy
,sum(amount) over (partition by gl,curr,to_char(dy,'MON-YYYY') order by dy) mtd
from   src;```

I can't get my head round your YTD calculation - you are adding the same values up again and again.
All you should need to do for a YTD column is to just sum everything for the year up to that point:
```select gl
,curr
,dy
,sum(amount) over (partition by gl,curr,to_char(dy,'MON-YYYY') order by dy) mtd
,sum(amount) over (partition by gl,curr,to_char(dy,'YYYY') order by dy) ytd
from   src;```

Sorry for messing the way i described my needs.

Good input, i will try out with OVER Clause.

If you have any URL's to learn analytical functions like OVER Clause ( with well explained examples ), Please share it.

If i have any doubts, will get back again.

Thanks for all of your responses.

Maybe the documentation?
Database SQL Reference
Chapter 5 Functions
Section Analytic Functions

And examples in each and every analytic functions.
