Count number of decimal

Hi all,
I have the table
List
flag_circ char(1)
impo number(11,3)
and I have to update flag_circ, if the number of decimal of the field impo, are 0 or 1
For example
Impo value
123,444 --> no update
123,44 --> no update
123,4 --> yes update
123 --> yes update
I'm trying those functions like round, mod, trunc, but don't work!
Some suggestions?
Thank's form Madrid
Paolo

Hi,
Try this
UPDATE list
SET flag_circ = somthing you want
WHERE INSTR(impo,'.',1,1) = 0
OR
LENGTH(SUBSTR(impo,INSTR(impo,'.',1,1)+1,2)) = 1
My tests:
SQL> WITH data_Set AS
2 (
3 SELECT 1 row_no, 1221.4554 text_col FROM dual
4 UNION ALL
5 SELECT 2 row_no, 1221.4554 text_col FROM dual
6 UNION ALL
7 SELECT 3 row_no, 1234 text_col FROM dual
8 UNION ALL
9 SELECT 4 row_no, 2343.5 text_col FROM dual
10 )
11 SELECT row_no FROM data_set
12 WHERE INSTR(text_col,'.',1,1) = 0
13 OR
14 LENGTH(SUBSTR(text_col,INSTR(text_col,'.',1,1)+1,2)) = 1
15 /

Can not change the number of decimal places in the normalization of result

dear all
    i want to see the proportion of some data, for example, the income of May is 300, and the total income is 1000, i need to display it like 33.33% . so i set the
Calculate single values as normalization of result, and then it display 33.333%, i like to display only two number of decimal places, so i set the number of decimal places as 0.00, but i doesn't work, it still display three decimal numbers.
    maybe you say i can use the percentage function like %CT %GT %RT, but i need to allow external access to my query, so the i can not use those functions.
    can somebody helps me ? your advice is appreciated.

hi,thanks for your advice, but that doesn't suit for my problem.
before i set the normalization of result, i can change the decimal values. After that i cann't.
In your thread, someone proposes use the T-code OY04. but this wouldn't help. As i change to other key figure, such as user quantity, when i set normalization of result, it still display 3 decimal values.
i think the point maybe lie in the normalization of result. please advise... thanks...

How to Count Number of completed line items in past 6 months / 12 months ?

How to Count Number of completed line items in past 6 months / 12 months ?
Hi,
I am trying to count "Number of Completed Line Items in Purchase Order Document" for my Key Figure ZPO_CNT.
Purchase Order document = ZEBELN
Line Item = ZEBELP.
I need to find and count if the Line Item has been received in the past 6 months from today and similarly in the past 12 months.
I have "Delivery Completed" field, ELIKZ.
So, based on this would I be able to calculate it in Query Designer?
If so, Please let me know how

Hello Deva
If youe want to calculate the completed line item for last 6 or 12 month then i think u will be displaying the query data for these montrhs...create a customer exit to give you date range and restric it in filter area....
Now Choose any of the below option
1. I would suggest to implement an additional key figure "counter" in cube and fill values with one for which delivery is completed.
Now use calculated key figure in Query Designer based on logic
IF counter = 1 THEN counter ELSE 0
OR
2. create a formula variable based on ELIKZ and use replacement path variable, it will display you no. of docs for which delivery is completed....
Award points if it solves your problem
Revert back in case of further assistance...
Thanks

How to count number of edges using PXIe-6363 Counters

Hello,
I am trying to count number of edges in a test signal in a 50 ms duration. I am using PXIe-6363 card and connecting the test signal to CTR 0 SRC (PFI 8). Is it a correct connection? What else do I need hardware-wise to make a correct set up for this application?
Thanks
Jeet
Solved!
Go to Solution.

Hi Jeet,
When you say interrupt signal, do you mean a pulse that will pause your counter task? If that is the case, and you want to pause your task with a digital pulse, you need to use the DAQmx Trigger Property Node and set that to Pause, Trigger Type. As you said, you can connect that signal coming from the chip to any PFI line and then set that line as the source of the property node.
There is an example that you can use that does exactly what I just described. This example is called Count Digital Events-Pause Trig.vi, and you can find it by going to Help>Find Examples..., then on the NI Example Finder window go to the Browse tab and navigate in the folders to Hardware Input and Outpout\DAQmx\Counter Measurements\Count Digital Events.

Hi
Instead of using counter in a loop use describe statement.
Describe it_sflight.
the no of rows will get populated in the system variable sy-tfill.

DATA counter TYPE i VALUE 0.
start-of-SELECTION.

How to get the number of decimal places configured for a site column

Hi,
I have a column 'SampleNumCol' of type Number, the number of decimal places to be displayed is configured as 2.
The column conatins a value, but when retrieved programatically is displayed as 5.00000000 instead of 5.00.
I am retrieving this column using listitem.Properties[field.InternalName].
I need to trim the decimals based on number of decimal places configured for the site column.

Get the field as SPFieldNumber and then check DisplayFormat which returns

Change number of decimal in general settings after working .

Hi,
My customer was upgarded to sap2007 and changed the number of decimal in the "Amount" field to 4 ( it used to be 2)
now after working a while he needs to change it back.
Do you know what are the consequences of updating this field using an update query?
thanks.

Disaster - first SAP does not permit direct updates to the database it is a violation of agreement with both customers and partners.
Second - even if you were to update the field your reports, fiancials, etc would never match due to rounding and display differences.
I am guessing that the client does not like the 4 decimals on the forms and if this is the case they could be changed to display a rounded field by creating a new field, linking to the old field and using a formulae such as round(field_123,2). You would then die the old field.
It is for this reason that SAP clearly warns you that setup of decimals are critical and cannot be changed after transactions are entered.

How to count number of ones in table

Hello,
i created one table 16x32 each cell is updating 1 byte of data,how to count number of one in all cell,and is it right way to calculate check sum??
thank you

The simplest way is to call GetTableCellRangeValues with VAL_ENTIRE_TABLE as the range, next summing array elements.
But I don't understand your comment on checksum, so this may not be the more correct method for your actual needs: can you explain what do you mean?

URGENT HELP NEEDED: counting number of particles from image

this image on the left is showing particles
hello i want to create a small VI that can count number of particles from a image that i load up. please see the attached image of particles and the VI printshot.
I have used the tutorial "counting number of particles" but still the above VI does not work. it shows the number of particles = 1.. I do not know why it is doing so??
I am not an expert in Labview so please can someone tell me where the problem is. sorry i could not attach the VI file itself but i have given an image of it..
after anyone has solved this problem, i have to create a live system that will get live images from the camera - four frames every sec and the above VI has to count the
number of particles for each frame and output to the user?? is this possible can anyone do it for me???
p.s. in the above VI i read the image from file and count the number of particles. i do not do it to the binary image becuase the binary image is only a black screen
when i run it
thankyou

Hi Farhan,
Vision Assistant would be the best option to create some steps which you can then export to LabVIEW. You should try using the IMAQ Find Circles.vi. The attached image helps you find the number of circles of an image acquired from a camera. I have used the IMAQdx VIs in this example.

What is a best practice for counting number of payments in Payroll Run?

I'm trying to get a feel for what people are using as a means for counting number of payments being created during a payroll run. I would like to get a total number of checks, direct deposits, wires and zero net checks. My initial thought is to use the Pre-DME number "Selected and Evaluated Persons". This number seems to always match the number of persons "Selected" and "Evaluated" in posting to FI/CO.
Since many companies are restricting use of SE16 and access to many of the BT tables is locked down, I would like to use something that the end user has access to and can easily use. I don't believe the spools from RFFOUS_C and T are appropriate since it would have overflow pages (2 page REM Statements) in that number and thus would not be an accurate reflection of total number of payments.
I would appreciate your insight and thoughts on this topic.
Thanks!

Hello Jennie,
This is what we do every payroll:
1. After running live payroll and before exiting our users run wage type reporter /559 to get the payroll net pay. They also run Postings to FICO simulation run to check payroll net pay GL account. This match all the time. So this is the first pass.
2. They finish all subsequent activities in PRD run upto RFFOUS_T.
3. We have developed a custom report which almost looks like REGUH which gives the net pay details by every payment method and amount to be deposited or paid. We match this report from the output we received from step 1.
4. Run postings to FICO live and check the payroll net pay GL account for final validation.
The steps might sound tedious but of a great use.

How to count number of rows in table

can I get number of row in table except Count(*) in pl/sql
is there any other way

Also posted and answered here
how to count number of rows in table
count(*) will be the fastest way. It is only slow if the table has a vast number of rows, in which case why do you need to know the tables has 73552436467721 rows and not 73552436467737 rows. It doesn't seem to be much use. Either that or you are counting them a lot, which again seems rather pointless.
