Global variable not updating in main vi

Hello Friends,
I had already prepared a vi with global variables assigned in it previously... now I have updated 4 more global variables to this vi... The output at the read jet data sub vi is updating whereas the force and the rpm values are not updating in this main vi.... I call this as main vi because I just see the final output here, all in one front panel...
If i click on run once, I get 1 value and in order to get another value i should stop and run again.
Could you please suggest me how can I get it updated continuously?

LabVIEW will execute whichever one who wants to first.
You can use error wires to force an order of execution.
I would recommend looking at the online LabVIEW tutorials

DB Look up error: Column/global variable not found-Error in EDO-ExecSearch

Hi all..
In my application I am usind database look up with DB2 database..
As soon as I click on Database Look up button,it throws an error that [[IBM] [System i access ODBC driver] [DB2 for i5/OS]SQL0206 - column or global variable not found. [Error in in EDO-ExecSearch]].
Please anyone tell me where the problem is????
Thanks in advance.

I never realized this myself, but you can have more than one alias in your hosts file. I found that some programs look for <code>localhost</code> and others look for whatever your server name is. To satisfy both of those situations, just put your server's name after <code>localhost</code> so you'll have something like this:
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 home.matrix.dk localhost matrix

Shared variables not updating in exe

Hi,
I've created a project with 2 vi's, they share data via Networked Shared Variables, one vi writes while the other reads.
The data is passed between the 2 vi's whilst running in the Labview 2009 SP1 development environment, but when I create an exe, the screen values in the reader vi do not update at all.
In the build specification I've tried both including the vi's which reference the shared variables and the
option to list the shared variable libaries for deployment at run time, as methods to overcome the problem.
Please, any clues why the exe should fail to allow shared variables to pass data ?
thanks,
Gary.

Hey Gary,
I've just created a project to replicate the issue you are having and indeed when I built the application, the Shared Variables were no longer working. This is because I hadn't deployed the Shared Variables in code; which I think may be the problem that you're having at the moment. When create a Network Published Shared Variable library in LabVIEW, it auto-deploys itself for the development environment; but this is definitely not the case for when you build an executable. Instead, you must deploy the library yourself in code.
In the attached zip folder, please follow the following instructions and hopefully you'll be able to fix your VI:
Unzip the folder and extract the files.
Open up the project.
Look at the project layout. Notice the SharedVariableLibrary.lvlib and inspect the Shared_Double variable.
Look at how the Reader.vi and the Writer.vi interact with the variable.
Go into the Main.vi. See that I make an Open Application Reference VI and Invoke Node to manually deploy the library in code. You'll have to change the path to this library to match the directory structure of your own computer, so just make sure it navigates to the library in the extracted folder.
Check out the Build Specifications. I've done nothing here except ensure I only include the Main VI. Finally build the VI and run the executable.
You should see that this will give you a working Shared Variable setup. The Machine Name input for the Open Application Reference is blank because you only want to communicate with the localhost i.e. Your computer. Therefore by explicitly deploying all libraries you require, your VIs should be able to communicate effectively.
Does this solve your problem?

Cleared item not updated in Main Bank Account FEBAN

Hi Experts,
i entered manual bank statement through FF67 and saved it. then i went to FEBAN to view if there was any open item left in this statement so that it can be posted manually. in FEBAN i found not a single open item in this statement which meant that all items of bank statement were transferred to main account. but when i viewed the main account G/L through FAGLL03 i found no item transferred. the cleared items shown in FEBAN are not transferred to main account. this has happened with only one statement. all other were posted successfully and values were updated in main account. Please guide me what do i have to do in order to fix this,
Regards,

Hi faizan,
I would suggest you to delete that statement & re-process the statement via FF67 in the back ground or creating log rather than you continue with FEBAN.
However, if you want to continue with FEBAN then go to EDIT --> Posting Mode --> Foreground or Background.
In case of any issue, please let me know.
NOTE: if it is helpful please assign the point.

Problem with Bind Variable not updatable.

Hi all,
I'm using Jdev 11.1.2.3.0. In my VO, I created a Bind Variable and set it NOT UPDATABLE. Then I created a View Criteria with some other Bind Variables.
I use this View Criteria in a search page, but at runtime I see also an inpunt text for the variable that is set NOT UPDATABLE and I can change its value.
Of course if I try to change the value and I do the search, I get an error.
This is the VO source:
<Variable
Name="UlssVar"
Kind="where"
Type="java.lang.String"
IsUpdateable="false">
<TransientExpression><![CDATA[adf.context.current.sessionScope.get('ulss')]]></TransientExpression>
</Variable>
Is it a ADF bug?
Thank in advance.

Hi,
try selecting the bind variable and open the Property Inspector, under UI Hints, set the "Display Hint" to hide. This should hide it (No bug for this reason)

Function module Global variables not cleared from memory?

Hi,
This is may be simple & stupid question ( after posting 4242 posts ):)
" Declaration in TOP
data : begin of i_y1yatt occurs 0.
        include structure y1yatt.
data : end of i_y1yatt.
types: begin of t_yatt71.
       include structure yatt71.
types: tcode like sy-tcode.
types: dflag type c.
types: end of t_yatt71.
data : i_yatt71 type standard table of t_yatt71
               with default key with header line initial size 0.
This is code in the function module.
loop at i_y1yatt.
    move-corresponding o_y1yatt to i_yatt71.
    if i_y1yatt-werks eq 'N501'.
       move space to i_yatt71-werks.
    endif.
    append i_yatt71.
    " Here this internal contains the previous entry
    clear i_yatt71.
endloop.
This function module is called 25 times in a minute.
My problem is this
For example : 1st tranmission is called this fm with 50 records,
and 2nd tranmission is called fm with 10 records.
My results are showing
last record in the 1st transmission is still on the memory while calling 2nd transmission. ( Here in int table I_YATT71 still contains the 1st transmission's last records during the 2nd tranmission call)
As per my knowledge if each time calls comes in to fm all gloabl variables get cleared. but some how this not happening.
Anybody come across this scenario.
PS. I know i need to use clear statement within the loop as first statement.
a®

You must understand that when calling a FM, you load the entire function group into memory. IF there are global variables, then they are "alive" for the entire duration of the program execution. Meaning if you call the function numerious times, or even if you call another function within the same function group, the functions still have access to that same global variable space, so it must always be cleared manually by the developer at the required points. You can not rely on the runtime to clear the global variables at the end of the function call. So you should clear all you globals as the first operation in your function module call, if that is what is required.
Is this clear?

Modbus I/O Server Shared Variable Not Updating Immediately After Flush

Hi everyone,
Weird issue here... If I create a Modbus I/O server in a LabVIEW project, bind a shared variable to a holding register, write to the shared variable, flush, and read back, the value returned in an immediate readback is NOT the value I previously wrote. I've attached an example snippet.
In this example, PLC Command Complete is TRUE coming in. I write a FALSE to it. I flush the shared variable buffer. I read back PLC Command Complete. When I do this, PLC Command Complete will return TRUE (???), and after 100ms or so, return FALSE. How is this possible??
Some notes:
The shared variable is NOT network buffered.
The slave is NOT altering the value of this variable; only this snippet of code is.
Altering the refresh rate of the Modbus server does not affect the outcome.
If anyone has any idea as to what's going on, I would greatly appreciate it!

Couple of points.
First, your screenshot shows network shared variables, not single process!
Next, network shared variables take time to update (much longer than NI tell you!) If you knock up a little timing noddy to set a variable and then loop reading that variable until the transition comes through you get results like this (runnng from the programming environment, I've not tried with a compiled exe):
Network shared variable, no flush - approx 20ms (NI say is should be 10)
Network shared variable, flush buffer - very fast (faster than the ms clock resolution) but still took between 14 and 20 iterations of my loop before the change percolated through (certainly not what you would expect)
Single Process variable - instant (even without the flush)
This has caused me so many problems in the past (my own race conditions are bad enough without NI throwing in extra ones with this unexpected behaviour) that I try to avoid network shared variables now.
Change yours to single process and you should be fine (or do they need to be NS?)

Global variable not being seen by other formulas

Hi
I've set a global variable in my report, but other formulas don't recognise it. What have I done wrong?
In my group1 header I have a formula 'w' which is just
Global Numbervar v1 := 0;
In my details section I have a formula 'x' which is
if {Command.INVLINETYPE} = 1 and previous({Command.INVLINETYPE}) <> 999 then
   {Command.LINEVALUE};
    v1 := v1 + {Command.LINEVALUE};
else
if {Command.INVLINETYPE} = 999 and {Command.ORDERNO} <> previous({Command.ORDERNO}) then
   {Command.LINEVALUE}
else
   0
this gives an error of 'Missing ) ' when I try to save it. If I put in a local variable in place of v1, the formula saves. This is the first time I've used variables in this way, which I'm having to do to try to sum this formula which uses Previous. Thought that I could create a global variable and use it to record the total.
Thanks
Steven

Sharon
thanks for this. Unfortunately I get the same when I move the ).
Is it something to do with where the Global variable is declared (though I have tried moving it around).

Variables not updating in Snippets

Hi there. I'm currently still on RoboHELP 8 and about to upgrade but I've found this issue is still a problem when I've upgrading my project to a trial version of RoboHELP 9 (with the critical update applied). It's on my local drive - no networks involved.
I've got a large project (around 2364 topics) and I use variables and snippets a lot in the project. The developers have had a total redesign of the software interface and I updated a couple of the variables to guage how much work it will take to totally update the help. In normal topics there doesn't appear to be a problem - but when a variable is in a snippet, the values aren't updating in the view (as per the above image).
If you preview the topic, the variables update but each time you open the topic, it's reverted to displaying the wrong values.
The compile uses the correct value so it's only a visual thing.
The problem is that every time you open one of these topics, it looks wrong and you have to check the snippet to make sure it's been updated. I'm very concerned that I will get complacent thinking that what's displaying on the screen is a visual firfie and actually overlook a variable that I haven't updated.
Has anyone else experienced this problem? Any comments would be greatly appreciated.
We will be updating very soon and at least I can turn the snippets into html in each of the topics to fix the display issue but that would be defeating the purpose of having snippets.

Quiz variables not updating

I am experimenting with the quiz variables in Captivate 4. I
have a Flash file that loads a Captivate file. In Flash, I am
pulling some of the variable data from Captivate... however, only
some of the variables seem to be updating and I am not sure why.
For instance, I have a few slides with click boxes that are set up
to report quiz data.
The following variables don't seem to update... at least
publically that I can pull from Flash:
cpQuizInfoLastSlidePointScored
cpQuizInfoPointsscored
cpQuizInfoTotalCorrectAnswers
The following variables seem to be updating fine:
cpQuizInfoTotalQuizPoints
cpQuizInfoTotalProjectPoints
I can also create a custom variable that seems to update
properly.
Thanks in advance.
gregb

Hi,
The below variables gets populated once you start taking the
Quiz.
cpQuizInfoLastSlidePointScored - returns the points scored
for your last question. You need to have this variable after every
Question slide.
cpQuizInfoPointsscored - returns the total points scored for
the Quiz. You need to use it after the last Question.
cpQuizInfoTotalCorrectAnswers - returns total correct answers
after taking the Quiz.You need to use it after the last Question.
Below variables gets prepopulated and need to not require
taking Quiz -
cpQuizInfoTotalProjectPoints - Total points for the project.
cpQuizInfoTotalQuizPoints - Same as above one
Please take the Quiz and check if the variables are getting
populated appropriately and let me know if it helped.
thanks

ITunes 10 - iPhone 4 Device playlist not updating from main iTunes Playlist

Installed iTunes 10 and synched with an Apple iPhone 4. After the first install, I could see all of the Playlists displayed in iTunes when I selected to sync Music on the iPhone using the 'Selected playlists, artists, albums, and genres'. After the initial install of the iPhone 4, I add or rename playlists in the main iTunes app and these new playlists do not appear at all in the iPhone Music playlists to be selected.
I can add songs to a playlist and the iPhone playlist gets the new tracks OK.
I tried renaming a playlist that showed up OK in the iPhone Music Playlists and the playlist disappeared from the iPhone Music Playlists.
All of the playlists work fine within the main iTunes window, I can add, delete, rename playlists without any issues there. The only issue I have is within the iPhone 4 Music Sync Music tab where I select playlists.
I reinstalled the iTunes 10 and did a restore of the iPhone and the problem persists.

The same issue occurs with my iPad.
Spoke with Apple twice and the attempts so far have not resulted in the problem being fixed. What's been done to date is:
- reinstalled iTunes 10
- move the iTunes Music Library.xml file to desktop and then selected the option to import the library using the xml file from the desktop (this took about 12 hours to run, I have about 108,000 tracks in my library)
After these two attempts, I continue to have the issue whereby playlists showing up on the Devices on iTunes to select playlists do not match with the playlist within the main iTunes window.
Any other ideas of what could be done?

Global Address List Not Updating in Outlook

I have a question from user about Global Address Not updating in Outlook. We have a user whom name was changed, how ever his new name didn't appeared on Global Address List in Outlook client
I did explained to him that Outlook require about 48 hours to reflect a new update Global Address List then he asked me why previously (24 hours) his old name also disappear from Global Address List.
Could you please advice.

Hi,
Please check whether the new name is updated in Global Address List when the user accesses his mailbox from OWA and Outlook Online mode.
If the new name is also not changed in GAL for OWA, please refer to bawzman's suggestion to run cmdlets to update globel address list in Exchange server.
If the issue only happens in Outlook cached mode, the issue should be related to Offline Address Book which is used for Cached mode as Globle Address List. We can manually download it and update the address list by clicking Send/Receive > Send/Receive
Groups > Download Address Book to have a try.

Issue with Global variable in FM

Hi experts,
I have created two functional modules under same function group and declared the internal table (ITAB)as global variable ,
i have populated the data to to ITAB n first function module , and These FM are used in a program , when i debug the program , the data is populated to 1st FM and but in 2nd function module the ITAB is null only internal table structure is available.
please let me know the reason.
Thanks NK

thanks all, the program ( it also an FM) ,which is calling the 2nd FM is in background mode, i think thats the reason ITAB values are not populated.
i ts working fine with IMPORT/EXPORT but my lead says it is not advisable and they are obsolete in ECC 6.0,
---> declated iTAB as global variable.
---> call FM1 --populate itab
call function " MAIN_FM" in update task.
---> fm2 cllaed in side MAIN_FM, ( here values not populated)
please suggest global variable not filled incase of background mode.
thanks
NK
