How to get the desired total of Random numbers ?

I m in a big problem and want a urgent solution.
I want to randomise numbers with specified limit and the total of all the randomised numbers should be desirable.
e.g. if i m generating random number 24 times in a loop then the total of all the gerenrated numbers should be 100 and each randomised generated number should not be greater than 6.
Please help me out. is there any method from which i can get, desirable total from the gererated random numbers ?
Please help.
thanks in advance

In my usual manner, I'll throw in a couple of ideas and leave others to discard them again :-)
Pick random numbers. If, at some point, the sum goes over 100, throw away the last number at instead put in the number that will make the sum exactly 100. Then put in 0 until you have 24 numbers. Those 0s won't look random. If it helps, shuffle all the numbers so the 0 come in random places in the sequence. If it's still not random enough, discard the whole idea. If, on the other hand, you still are m numbers short of 24 numbers and the sum goes under 100 - (m * 6), in a similar manner stop using randomness and throw in the numbers needed to hit 100. Shuffle to distribute the 6s.
Another idea, there are 100 ^ 24 or 10 ^ 48 ways to put 100 balls into 24 buckets. Find out how many ways there are under the constraint that you can put at most 6 balls into a bucket. Enumerate them, pick one at random and generate it. I would say that this should give you a good randomness, but does it also look that way under your requirements?

Hi Frds.
     How to get the Grand Total in Module pool Screen

for each matarial has different moving . But in my case matarials is doesnt matter here

Hi
You need to calculate the total in a module of PAI (or PBO) event:
PROCESS PAI.
   LOOP.....
   ENDLOOP.
MODULE CALCULATE_TOTAL.
MODULE CALCULATE_TOTAL.
    GRAND_TOTAL = 0.
     LOOP AT ITAB,
        GRAND_TOTAL = GRAND_TOTAL + ITAB-PWB.
    ENDLOOP.
ENDMODULE.
In this way the grand total will be calculated as soon as the user presses enter or another command.
You can't insert the calculation in the loop of table control, because this loop runs the visible lines only, so it's better to calculate the total out of those loop,

How to get the measure total at row level for another measure calculation in DAX?

Hi There,
Using DAX, I am trying to get an expression for a calculated measure as follow:
So basically, I would like to get the AMeasure total highlighted in yellow in the A2Measure calculation:
Smeasure -(Ameasure total * WMeasure) where Ameasure total is the one highlighted.
I think my question would be how to get the total of a measure in order to used in the calculation of another measure.
Thanks and best regards,
Joss

Hi Joss83,
If you're trying to get the result for [AMeasure] at the total level (i.e. 5.09 in your example) you can do this by creating a version of this measures that is evaluated after ignoring the filters (indirectly or explicitly) placed on
the 'Customer' and 'Player' columns. You may also need to ignore the filters place on some other tables or columns that must be ignored in order for the correct total to be returned.
Without knowing much more about your data model, I can only take a vague guess as to what this calculation would look like in your scenario:
AMeasureTotal:=
CALCULATE(
[AMeasure],
ALL(Customer[Customer]),
ALL(Player[Player])
You can read more about the 'ALL' DAX function here:

How to get the max total sale by date on every store

I am trying to write a query in Oracle which will return both the store_id and the maximum total sale by date

Hi,
Whenever you have a question, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).
See the forum FAQ: https://forums.oracle.com/message/9362002#9362002
Hjava wrote:
I am trying to write a query in Oracle which will return both the store_id and the maximum total sale by date
Do you mean you want to see the store_id that had the maximum total sale?
In general, this can be done with a Top-N Query, using an analytic function such as RANK. For an example, see http://forums.oracle.com/forums/thread.jspa?messageID=3739610
If you only want the date, the maximum total from that date, and 1 column from the same row with the maximum (e.g. store_id), then you might be able to use the aggregate LAST function instead.
What results do you want in case of a tie? (That is, if 2 or mote store_ids have the same total sale on a given date, and no other store_id has a higher total.)

Add summary columns in your data model. Where to put them exactly depends on your report. E.g. if you want a grand total at the end of the report, you create the column outside the query. The Object Navigator shows a Summary Columns node beneath the Queries node for these columns.
