Problem with AT command in LOOP

Hi Experts,
here i ve a problem like, in my table there are 3 PSPHI(projects) values,
if i loop n calculate the sum it is getting total amt for 3 PSPHI values,
but i want every end of PSPHI i need sum.
the below code is working fine if there is no AT coomand, if i put AT END OF PSPHI it is giving 00.00 values.
LOOP AT it_final into it_output.
   AT END OF PSPHI.
    if it_final-wrttp = '04'
       AND it_final-vorga = 'COIN'
       AND it_final-beltp = '02'
       AND it_final-versn = '000'.
   t_pla_rev = t_pla_rev + it_output-wlp01.
    MOVE it_output-wlp01 TO pla_rev.
    sum = sum + pla_rev.
      if sy-subrc EQ 0.
        else.
        write:/10 ' u r not ok'.
    endif.
e ndif.
append it_output.
*ENDAT.
ENDLOOP.
write:/10 'total amt is', sum.
could anybady check where i gone wrong pls...
Thanks in advance,
sudharsan.

Hi,
What is your table structure.
The command AT ........ENDAT work in sequential order.
Let me explain with example.
if your table itab has two column column1 and column2
loop at itab into wa.
at new column2.
// This will execute when the Value of column 1 change or column2
// change.
endat.
endlloop.
The solution of your problem is.
Change your internal table column order ,
Put the column first for which you want to calculate the sum.
Thanks & Regards

Problems with 'df' command

Hello folks,
I'm having some problems with df command:

Problem with two parallel While loops

I have a serious problem with controlling two parallel While Loop. Here is the deal:
I have written a VI to send a series of commands called Cycle through Serial Port to a custom hardware. One of these commands is setting motor pressure by sending it's command and changing it's voltage. After setting desired pressure I have to read and control motor pressure, again through serial port in a parallel loop. There is a Pressure Sensor in system and I can obtain current's motor pressure by sending a command and receiving pressure value. In the first While loop I send some commands to hardware including Pressure Setting Command trough a state machine. In the second While Loop I read pressure value and then decide to increase motor voltage or decrease it. Now the problem is in communicating these two loops. In cycle after "Init" state when state reaches "Pressure 2 Bar" motor voltage will increase. Meanwhile I have to control this voltage in parallel While Loop. As you can see I used Local Variable to communicate between these two loops. The problem is that loops are not synchronized. Specially when I switch to "Pressure 3.8 Bar" state during cycle running control loop (second while) is still working based on "Pressure 2 Bar" state not 3.8 bar. Because of this motor pressure goes to 3.8 bar for a sec (becuase of "Pressure 3.8 Bar" state) and comes back to 2 bar (because the second while still has not gotten that new state,most probably cause of all the delays in the loop) and after couple seconds it goes back to 3.8 bar.
I really don’t know what to do. Is there a way to fix this? Or I should consider a better way to do this?
I went through Occurrence Palette but couldnt figure out how to embed that in the VI.
Sorry for my poor English. I attached VI and it's subVIs as a LLB file. I can explain more details if somebody wants.

I make it a point to NEVER have a WAIT function inside a state machine.
It sort of defeats the purpose, which I define as "Examine current state; decide whether you've met the conditions to advance to another state, then get out".
For example, I have a single state machine VI controlling four identical instruments, via TCP connections.
For some functions, that means issuing a command, waiting 60 seconds, then reading results.
If I waited INSIDE the state machine, then it's tied up waiting on one device and cannot handle any others.
Not a good plan.
To handle this, I have a loop which calls the state machine. After issuing the command, the state goes to "Waiting on Response", and there is a target time of 60 seconds from now.
It's called over and over in that state, and each time merely compares NOW to the target time. If NOW is past the target, then we read the results.
the state machine can tell the caller when to call back; that's how I distinguish between an urgent need and nothing-to-do.
By having the CALLER do the waiting, instead of the state machine itself, the state machine is free to handle another device, or do something else on the same device.
You should be calling the state machine over and over and over anyway. So, have the state machine "control the pressure" on every call, and THEN examine whatever state it's in.

Problem with shell commands and scripts from an Applescript Application

Hi-
I am fairly new to OSX software development. I am trying to build an application that creates a reverse SSH tunnel to my computer and starts OSXvnc. The idea is that my Mom or anyone else who needs help can connect to me without having to tinker with their firewalls.
There are plenty of resources on how to do this, and I have found them. What I have a problem with is the following.
I am building this application in Xcode as an Applescript application, because Applescript and shell scripting are the only forms of programming I know. I use an expect script to connect through SSH, and a "do shell script" for the raw OSXvnc-server application to allow screen sharing.
The problem is that when I click on the button to launch OSXvnc-server or the button to launch SSH, the application freezes until the process it spawns is killed or finishes. For example, I can set SSH to timeout after 60 seconds of no connection, and then the Applescript application responds again. I even tried using the ssh -f command to fork the process, but that doesn't seem to help.
I am also using "try" around each of the items.
What am I doing wrong? How can I make the buttons in my app launch SSH and OSXvnc-server without hanging the application while it waits for them to finish?
Thanks so much!

See here for an explanation of the syntax.

Problem with ResultSet in a loop

hi,
i have a probleme with ResultSet when, my code is bellow
ResultSet rs = stmt.executeQuery(sql);
sql="SELECT NAME FROM prestationtemp";
rs = stmt.executeQuery(sql);
String sqlDel="";
while (rs.next())
sqlDel="Delete from prestation where NAME="+rs.getString("NAME");
stmt.executeQuery(sqlDel);
the problem is that the loop iterate just once like if there is just one record, and if I remove stmt.executeQuery(sqlDel); from the loop it iterate normaly.
thanks in advance.

you will need to use 2 Statments e.g.
Statement stmt1 = connection.createStatement();
Statement stmt2 = connection.createStatement();
ResultSet rs = stmt.executeQuery(sql);
sql="SELECT NAME FROM prestationtemp";
rs = stmt1.executeQuery(sql);
String sqlDel="";
while (rs.next())
sqlDel="Delete from prestation where NAME="+rs.getString("NAME");
stmt2.executeQuery(sqlDel);
} When you reuse a Statement, any resultsets previously created are automatically closed.
Looking at your code, it seems that you only need 1 SQL call:
Delete from prestation where NAME in (SELECT NAME FROM prestationtemp)
Much more efficient!

Problem with issuing command via CustomScriptExtension

I am trying to issue a CustomScriptExtension command to an Azure virtual machine from within my C# application. The CustomScriptExtension is installed in the VM and working. I verified this by issuing a test command via PowerShell. Essentially I am trying
to execute what would be the equivalent to the PowerShell command Set-AzureVMCustomScriptExtension, but in code.
Below is the code segment that I am having problems with:
ComputeManagementClient client = new ComputeManagementClient(AzureSessionInfo.CloudCredentials);
IList<ResourceExtensionReference> extReferences = new List<ResourceExtensionReference>();
IList<ResourceExtensionParameterValue> extParamValues = new List<ResourceExtensionParameterValue>();
string account = "{\"storageAccountName\":\"" + AzureSessionInfo.StorageAccount + "\",\"storageAccountKey\": \"" + AzureSessionInfo.StorageAccountKey + "\"}";
string scriptfile = "{\"fileUris\": [\"" + "https://teststorageaccount.blob.core.windows.net/testcontainer" + "\"], \"commandToExecute\":\"powershell -ExecutionPolicy Unrestricted -file " + "ScriptName.ps1" + "\"}";
byte[] bytes1 = System.Text.Encoding.UTF8.GetBytes(account);
bytes1 = System.Text.Encoding.UTF8.GetBytes(account);
string ScriptPrivateConfig = Convert.ToBase64String(bytes1);
byte[] bytes2 = System.Text.Encoding.UTF8.GetBytes(scriptfile);
bytes2 = System.Text.Encoding.UTF8.GetBytes(scriptfile);
string ScriptPublicConfig = Convert.ToBase64String(bytes2);
ResourceExtensionParameterValue extRef_Parameter1 = new ResourceExtensionParameterValue()
Key = "CustomScriptExtensionPrivateConfigParameter",
Value = ScriptPrivateConfig,
Type = "Private"
ResourceExtensionParameterValue extRef_Parameter2 = new ResourceExtensionParameterValue()
Key = "CustomScriptExtensionPublicConfigParameter",
Value = ScriptPublicConfig,
Type = "Public"
extParamValues.Add(extRef_Parameter1);
extParamValues.Add(extRef_Parameter2);
ResourceExtensionReference extRef_CustomScript = new ResourceExtensionReference
Name = "CustomScriptExtension",
Publisher = "Microsoft.Compute",
Version = "*",
ReferenceName = "CustomScriptExtension",
ResourceExtensionParameterValues = extParamValues
extReferences.Add(extRef_CustomScript);
AzureSessionInfo.CloudServiceName = "CS1000001";
AzureSessionInfo.VMName = "CS1000001";
AzureSessionInfo.ImageFamilyName = "Windows Server 2012 R2 Datacenter";
client.VirtualMachines.Update(AzureSessionInfo.CloudServiceName,
AzureSessionInfo.VMName,
AzureSessionInfo.VMName,
new VirtualMachineUpdateParameters
RoleName = AzureSessionInfo.VMName,
ResourceExtensionReferences = extReferences
I receive the following error message back from the call:
BadRequest: Invalid extension reference parameter value in JSON configuration data for the Role: CS1000001, Reference name: CustomScriptExtension.
I could only find very little documentation on this. Any help would be appreciated.

Thanks Mekh... after many hours of researching and trial/error, I figured it out.
The MSDN article I used previously led me down the wrong path. (see article here: http://msdn.microsoft.com/en-us/library/azure/dn781373.aspx). This may work for RESTful calls but not for .NET API calls.
The part of the code that was hurting me was where the command strings (account and
scriptfile) were being converted to Base64 encoding. This is NOT correct for .NET calls. Once I removed that, everything worked fine.
I came across this after researching the same commands used by Linux scripts. They don't convert to Base64 either so I wonder why this is included in the documentation at all.
In either case, I figured it out, but the documentation is very poor in this area (or all together non-existent). I don't even see where it is documented as to which JSON parameters names are supposed to be used, or even that JSON is required.
Also, related to the Update command, if you are truly "updating" the config, you must include everything about the original config (whether it changed or not) along with the changes you want to make. If not then you will undo ALL but the changes
you issued via the command.

Problem with runas command. Elevation error

Running on Win 8.1 Pro I'm facing a problem with runas.
What I'm trying to do is launch an mmc as my domain admin account.
Therefore I type this command from an elevated cmd (Right-click "Run as Administrator"):
runas /user:Contoso\MyDomainAdmin /noprofile mmc
This worked like a charm in Windows 7, and on my Win81Pro client it yields:
RUNAS ERROR: Unable to run - mmc
740: The requested operation requires elevation.
The account I'm logged in with, is local admin, and the UAC slider is set in the bottom.
In the eventviewer, I only see some special logons where my normal account is trying to impersonate my domain admin account, and the next event, the domain admin's session is destroyed.
If this is by design, how would I then run mmc as my domain admin and at the same time avoid its credentials being stored on the local machine?
Thanks in advance!

yes, you need to be local admin to be able to elevate!
I've tested this on a system here and I reproduce the issue you encountered. Some investigation showed running a program that requires elevation using runas is not possible http://msdn.microsoft.com/en-us/library/bb756922.aspx

Problem with cfhttp in a loop

Hi,
I am reading an xml file that contains emails with attachments (one email per item/node, but may contain multiple attachments). I am trying to save the attachments to our server. So I'm looping over the multiple attachments of a single email and using cfhttp to GET the attachments from another server and save them with the same filename on our server.
The problem is that it works for the first attachment - it's saved to the server, status code is 200 OK - awesome! But for any attachments after that, it does not save them and throws a Conection Failure error. No matter what attachments they are.
In trouble shooting I tried several things. First, inside of my loop of attachments, I can hardcode the cfhttp calls with the url and filename of the attachments - one right after the other - and all is perfect everytime!! But it obviously needs to be dynamic. I also tried to save a list of the attachment urls from the loop, and then call a separate cfhttp tag for each attachment in the list (so again, was in a loop) and it works for the first attachment in the list and not for the others (same errors as above).
Here's a simplified version of the code. I can't put in the real xml url, and when I set the "attachmentFilename" I left out that code because it works and is too much code. Also, the XML works fine. Please let me know if you have any suggestions, and of course, if you need more info from me!!
Thanks so much,
Kirsten

cfhttp.statusCode: Connection Failure. Status code unavailable.
cfhttp.errorDetail: I/O Exception: peer not authenticated

We've seen the peer not authenticated error quite a bit on our CFHTTP calls - are you trying to access the URLs via HTTPS? It seems the SSL certificate keystore that CF ships with does not contain all the vendor SSL certificates out there - when CF can't authenticate a cert, it throws that "Connection Failure / Peer not authenticated Error". In order to fix the issue, you have to import the SSL certificate of the site you are trying to access into the CF cert store on your server(s). If you are using multiple servers, you will have to import the cert on each server.
I'm sure a google search will turn up a step by step guide on how to do this, but the basic steps are:
Go to a page on the SSL server.
Double-click the lock icon.
Click the Details tab.
Click Copy To File.
Select the base64 option and save the file.
Copy the CER file into ColdfusionDir\runtime\jre\lib\security
Run the following command from the same directory (keytool.exe is located in ColdfusionDir\runtime\jre\bin) ..\..\bin\keytool.exe -import -keystore cacerts -alias UniqueName -file filename.cer
Restart Coldfusion
Hope that helps!

Problem with modify command....

Hi abapers,
loop at itab.
read table ifinal with key kunnr = itab-kunnr.
if sy-subrc = 0.
move: ifinal-dmbtr to itab-dmbtr.
modify itab index sy-tabix.
endif.
endloop.
Now the problem is that when i am using modify index sy-tabix it creating an additional entry
and when i am using only modify itab its working fine so wat could be the reason that modify index sy-tabix is
not working propertly.
Thanks

Hi Aarif,
I am assuming there is one-to-one relationship between itab and ifinal.
Try using following code.
sort itab by kunnr.
sort ifinal by kunnr.
data: l_index like sy-tabix.
l_index = 1.
loop at itab.
loop at ifinal from l_index.
     if ifinal-kunnr eq itab-kunnr.
        move: ifinal-dmbtr to itab-dmbtr.
    elseif ifinal-kunnr gt itab-kunnr.
       move sy-tabix to l_index.
       exit.
   endif.
endloop.
modify itab transporting dmbtr.
endloop.

Problem with DAQ in while loop and Graphs

Hello,
I'm new here so I apologize if I posted this on the wrong board
This is my "situation":
I need to make a simple PID controller which takes information (process variable) from an outside source (a NI's DAC connected through the USB port ) which is accomplished using NI-DAQ as an input, and the PID's output goes to the second NI-DAQ which is also connected using DAC to an actuator which in my case regulates the air pressure. (VI attached)
My problem is the following.
Both of the NI-DAQ I placed using DAQ Assist, require to be in a while loop.
-If I place them in separate loops, I have the problem of passing information between the Input NI-DAQ and the PID, and also between the PID and the Output NI-DAQ.
-If I place them both in one big loop, an error occurs saying that the selected buffer size is too small (Error -200609).
The timing settings for the DAQ's N samples, 100 samples to read at the rate of 1k (I also tried with Continuous samples and many different combinations of Samples to Read an Rate but without success).
Should I wire them with the same dt(s)?
The other thing I need to do (I'm also writing it here in order not to open new topics) is show the following 3 signals on a Graph (process variable (dynamic data type)(range 4mA - 20mA), PID output (double)(range 4mA - 20mA), and the Set Point (double)(range 0 to inf))
Firstly, is it possible to show the first two on a scale from 0 to 100 without changing the PID's output which needs to be 4-20?
Secondly, which graph should I use if I have different data types? (I tried the Waveform Chart, and succeeded in showing the first two; the third just messes everything up)
I would also have to make a legend explaining which signal is which (I see that this is possible with the Mixed Signal Graph).
I know this is probably too much to ask, but I'd be grateful for any help
Thank you in advance

My problem is the following. Both of the NI-DAQ I placed using DAQ Assist, require to be in a while loop.
-If
I place them in separate loops, I have the problem of passing
information between the Input NI-DAQ and the PID, and also between the
PID and the Output NI-DAQ.
This is the best option---Use QUEUE or Functional global or something else to tranfer the data to and fro
How do I make that QUEUE or Functional global?
-If I place them both in one big loop, an error occurs saying that the selected buffer size is too small (Error -200609).
Have
you tried increasing the buffer? Is the acquisition happening
parallelly (means to say the first DAQ not wired (error terminal) to
second DAQ)
Well the buffer is, at least how I understood it, the option Number of Samples when in Continuous Samples mode. Concerning the parallel acquisition, do you mean I should wire the error ports of both of the DAQs?

Problem with rename command in ftp_command

hi all ,
i am facing a problem in renaming a file by rename command...
this is how i am calling the fm ftp_command
CALL FUNCTION 'FTP_COMMAND'
    EXPORTING
      handle        = g_handle
      command       = 'RENAME l_templine_file l_templine_file1'
    TABLES
      data          = l_i_temp_line
    EXCEPTIONS
      tcpip_error   = 1
      command_error = 2
      data_error    = 3
      OTHERS        = 4.
IF sy-subrc <> 0.
here l_templine_file   - dev00227.header.tmp
l_templine_file1 - dev00227.header.txt
the fm is failing that the error meassage is FTP subcommand error
can u suggest where i am going wrong in this...

hi,
May be the command you are passing is incorrect syntax..
Pass the values like this..
l_templine_file = 'c:\dev00227.header.tmp' " this should be with path'
l_templine_file1 = 'dev00227.header.txt'" this is just the name of file
If not worked..then Try writing in small letters//
write
command = 'rename l_templinefile l_templine1'.
rewards if useful
Hope this solves..
regards,

Problem with running commands

Hi everybody !
I'm having a form which on being submitted runs a Linux Shell Script using the Runtime class .
Shell script consists of a command which prompts the user his username/password . I may sound absurd , but I want to know whether is it possible if I could prompt the user through GUI i.e my JSP page at this point of time .
Thanks in advance ,
Bye .

Pl .help with this problem .It's urgent ,very important & challenging too .
Someone , somewhere must have faced this problem .
Thanks a lot.

A problem with delays in timed loops and DAQ

I am programming a simulation for nuclear rewetting for a visitor centre at my company in Switzerland. It involves heating a "fuel rod" and then filling the chamber with water. The pump automatically starts once the rod core reaches 750C. After this, a requirement stipulates that flow rate be checked to ensure the pump is operating at the necessary conditions. If it isn't, the heater must be shutdown to avoid, well... meltdown. However, we must allow 10 seconds for the pump to respond, while still allowing a DAQ rate of 10-100Hz.
The challenge is that I can't add a delay in my main loop else delay all acquisition, but I can't figure out how to trigger a peripheral loop (with DAQ for the single channel of checking flow) from the main loop, and when the peripheral loop determines if flow has initalised, respond back to the main loop with the okay.
I think much of my confusion is in the interaction of the loops and the default feedback nodes that labview is putting in willy nilly. Would the only solution be to have two 'main' loops that don't communicate with eachother but rather do the same thing while operating on different timing? Tell me if you want me to post the file (although its on an unnetworked computer and I didn't think it would be too useful).
Thanks+ Curran
Solved!
Go to Solution.

Here it is! It is not in any form of completion unfortunately.
So reading in the temp with NI9213 and watercolumn height with NI9215, we determine to turn on the pump with NI9472. NI9421 determines whether the pump is on (there is flow) and I must respond accordingly.
I have 3 scenarios similar to this one as well, so having redundant loops with different timing like I mentioned would be way to heavy. I think I may have though up of a solution? At the time the pump is initiated, we record the iteration and wait for a number of iterations that correspond to 10s to pass before fulfilling the pump shutoff requirement?
