Hi rai,
I would appreciate it as kind of respect for forum participants if you would clean up your VI before uploading it (or images of its block diagram)…
That being said:
- Your inner while loops each run exactly twice. Replace them with FOR loops!
- Lots of unneeded operations, mainly induced by ExpressVI usage. Is there a reason to convert to DDT and immediately convert back to 1D array?
- You already calculate some Min/Max values. Ratio is just a division of two values…

Hi Rai,
You should post this into the LabVIEW forum rather than Real-Time since this isn't a Real-Time application. Your post will see more replies in the LabVIEW forum.
As far as your question is concerned, you can write the max and min from the respective loops to a local variable to send the data out of the loops to a third loop or just do the calculation in one of the loops. This would be ideal if you're trying to do this while the loop is running.

How to calculate the values

Hi Experts,
I have doubt, i have an internal table now i want to calculate the total for every group. How to do that?

Hello,
Use the COLLECT.
DATA:
wa LIKE LINE OF itab,
itab_sum LIKE itab.
SORT itab BY key.
LOOP AT itab INTO wa.
COLLECT wa INTO itab_sum.
ENDLOOP.
The itab_sum has the same structure like the itab where is the data to me summarized, and the wa has the line structure of the itab.

How to calculate the value of key figure by considering other char or kf

Hi
My requirement is like this:
I have a key figure which gives me the planned issues and receipts but i know that if only from locaton is blank and to loc is filled then that are receipts and if both the from and to location values are filled then it is issues,
can you pls let me know how i 'll put this logic in th reporting bex and how i achieve this by user exit or any other way
thx

Create two RKF, restrict first with [ from = '#' ] to get the planned receipts, and restrict the second with [ from <> '#' and to <> '#' ] to get the issues.

How to calculate the value from prompt and use the value as filter

Hi everyone,
I am designing a OBI query. I want to write a query and one of it filters comes from the dashboard prompt. Say I want to make a query to pull out the record for 3 consective years and user wants to enter the last year # and omit entering the first 2-year code#.Thanks!

Hi,
if i understand your question
you have a prompt for year.. and it's assigned with presentation variable, say: var_year
And you are just entering value for only one year, say 2000.
Then, the request (which is using that prompt value as filter) should display year values 2000, 2000-1 (i.e. 1999), 2000-2 (i.e. 1998).
Is this your requirement?
If then,
Hope you are using edit box as control for year prompt and assign a presentation variable for that prompt.
Now, in report go to filter of year prompt, click on advance > Convert this filter to SQL.
write here... *Times.Year between @{var_year} and @{var_year}-2*
And make sure that your var_year is integer, if not cast it to integer

How to calculate the mt_bf (optimum blocking factor) in mtio.h?

Hi geniuses,
One of our customers asks our tape driver to support the mt_bf defined as optimum blocking factor in mtget structure in mtio.h. The mt_bf is supported in MTIOCGET ioctl in Solaris native tape driver -- st. I can not find any Solaris document how to calculate the value for Developers. Please help me to figure out if you know the answer.
Thanks in advance!

IDVD is producing DVDs which chop the edges off my video. I have tried changing the aspect ratio between 4:3 and 16:9 but it hasn't helped. My TV is definitely on the correct settings. How can I solve this?

iDVD is producing DVDs which chop the edges off my video. I have tried changing the aspect ratio between 4:3 and 16:9 but it hasn't helped. My TV is definitely on the correct settings. How can I solve this?

One way to to put the videos into an iDVD slideshow
and set iDVD's Slideshow preferences to always scale slides to TV Safe Area.
However, some users have reported that the audio quality using this method is lessened. I've not noticed it but then I don't have a good ear when it comes to that sort of thing. If you add more than one video in the same slideshow do not select any transition.

I am Drawing the set of characters in Graphics, by Calculating the points using GraphicsPath for each Character. I Need to know how to calculate the distance should be given between the two characters?
I am using this code to generate points
PointF [] pnts;
var p=new GraphicsPath();
path.AddString("A","Arial",(int)FontStyle.Regular,50,new pointF(0f,0f),StringFormat.GenericDefault);
Matrix m=new Matric(1,0,0,1,0,0);
path.Flatten(m,1,0f);
pnts=path.pathpoints;
i am getting the points for all characters using the above code.
Now i am combining the two character Using the points generated by the above code. Eg "AB"

How to calculate the hour difference between two dates?

hi all,
how to calculate the hour difference between two dates?
eg i trying this...
((TO_DATE(TO_CHAR(GRNi.reference_date_4,'hh24:mi'),'hh24:mi') -
TO_DATE(TO_CHAR(NVL(GRNi.reference_date_3,SYSDATE),'hh24:mi'),'hh24:mi'))*24)*60 Act_Hr
Reg.
AAK

Hi
To break the diff between 2 dates into days, hours, minutes, sec -- you can use the following:
select to_char( created, 'dd-mon-yyyy hh24:mi:ss' ),
trunc( sysdate-created ) "Dy",
trunc( mod( (sysdate-created)*24, 24 ) ) "Hr",
trunc( mod( (sysdate-created)*24*60, 60 ) ) "Mi",
trunc( mod( (sysdate-created)*24*60*60, 60 ) ) "Sec",
to_char( sysdate, 'dd-mon-yyyy hh24:mi:ss' ),
sysdate-created "Tdy",
(sysdate-created)*24 "Thr",
(sysdate-created)*24*60 "Tmi",
(sysdate-created)*24*60*60 "Tsec"

How to calculate the phase difference between two square wave (acquired from two channel in one DAQ)

Hello everyone ,
I need a quickly help that as below :
I am trying use PCI-6220 to acquired six signals from one rotation encoder (channel A, channel B,channel Z ,and their non-signals) .The encoder out signals will be square wave and 4000pulses per revolution. I set it rotation at 300rpm speed. I need show every square wave of six out channels in waveform and measure the A-B phase difference to check if the value is correct (designed value should be 90deg) .
I have no idea how to measure or calculate the phase difference of two square wave base on synchronizate to acquire these two square wave from two channel on the PCI-6620....
Anyone can give a idea how to calculate the phase difference with two square wave ?
Thank a lot and Thanks again...
Tim

How to calculate the time between start trigger,first scan and first A/D in DAQ

Environment: Labview 6.1, N6052E DAQ board(max scan rate=333KHz, max channel rate=333KHz, settling time=3.5usec+1LSB)
I am using external scan clock 10K scan/s collecting data on 16 AI channels, and external channel clock 200KHz.
Could show me how to calculate the time betweent he start trigger, the first scan and the first A/D conversion?
Thanks

I read the one you give to me. still cannot work out. I am using Labview 6.1 DAQ vi, including AI config.vi. clock config.vi, AI control.vi, AI read.vi, working on colect data on 16 AI channels. So I belong to SCAN function and external scan and sampling timing, right?
But it says the T1 and T2 are determined by external signals. How can I calculate that?
T1=1/10KHz or T1=1/160Khz?
T2=1/200KHz?
Is the above correct?

How to calculate the difference of two totals which are of the same group?

Post Author: mingli
CA Forum: Formula
Hello,
I have an existing report which has a group defined. The group generates two set of data, at the footer of each set of data, the total is calcuated. Now I need to calculate the difference between the totals. For example:
                         value
set 1
      item 1         100
      item 2         200
      item 3        300
set 1 total         600
set 2
     item 1         200
     item 2          20
     item 3        300
     item 4         40
set 2 total       560
difference       40
My question is: how can I do this? I'm thinking about create a formula. But the problem is, these two totals have the same field name. Could someone help me out?
Thanks.

How to calculate the unit for RATE?

Hey All,
I am not sure if there is something standard for this or not.
I am calculating the 'Rate' by using 'Value/Amount' and 'Quantity' as follows -
Rate == Value / Quantity
I need to calculate the unit for the rate as below -
Rate unit == Value unit (Currency) / Quantity unit (Base_uom)
(for example -
if value is 1000 USD and quantity is 10 TO then Rate should come out as 100 USD / TO)
Could anyone please suggest how to calculate the unit in this case?
Many Thanks!

How to calculate the Current APC (Acquisition and Production Cost)

Hi,
Please help me how to calculate the Current APC.
The Current APC (Acquisition and Production Cost) is a calculated value based on Previous Year Acquisition balance plus any value changes up to the time of the report.
The Asset History Report (RAGITT_ALV01) calculates the Current APC value &
The Current APC can also be found in the Asset Explorer (transaction code AW01N) under Country Book 10/ Posted Values tab then the line Acquisition Value and column Posted values.
I suppose that the calculation of Current APC (Acquisition and Production Cost) is getting done in the GET statements in the report RAGITT_ALV01, but unable to find the actual logic.
Please help me.
Thanks in advance,
