Disable variable
hi experts...
i have 2 variables one for sales rep, and another is for record creator....
i have a single query which is containing both the variables... and i have 2 reports based on these 2 variables...
my requirement is to disable the 'sales rep' variable in the report based on 'record creator' variable.
and the same for another...
means... the user shud not give the selections for
'sales rep' variable in the report while he is enabled to give the selection for 'record creator' variable.
hope i can get a solution here...
thanking you...
regards,
nithin
hey... thats easy procedure but we shud not man...
how can we create a query just coz of variable problem...
here end user doesnt know nything...
we shud not make him more confuse by creating number of queries....
i think thats not advisable too....
try to find another way for me...

Experts,
I have a variable called Actual Version - 0.
I want to disable this text so that users can not enter in this variable.
Can u pls help me regarding this ?
Thanks
Manoharin the screen, where you created the variable, you can set the variable inactive for input.

Alright, so I've tried what feels like everything. First off, I am troubleshooting for WINDOWS 7.
After I reboot, the computer functions relatively fine. Great latency, no choppyness, no matter what I do. About two to three days later, it gets incredibly bad. Specifically when browsing the internet using any browser. The audio becomes terribly choppy
as the mouse lags across the screen. Running LatencyMon, I see tcpip.sys is always at the top. This issue only seems to happen the most when internet activity usage is high. Also, ndis.sys is always up there too, as well as NETIO.SYS
Any help would be so greatly appreciated!! I run a small web server from this PC, so this is quite critical for me. It never used to happen until I recently began getting Pool_corruption blue screens, later to be discovered they were caused by my GIGABYTE
motherboards utility driver files, which I took care of.
I haven't really made any changes to my PC, besides several driver updates in attempt to resolve this. I have since updated my BIOS to the latest version. I even tried using Auslogics Boost Speed to improve the TCP settings based on on my 50mbps internet
speed. Nothing clears the lag, but a reboot, which is temporary. I used to run this PC for up to two weeks before I rebooted, no issues.

CONCLUSION
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing
for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS
setup. Check for BIOS updates.

While I am waiting for the issue to start up again, I'd just like to cover some things you mentioned in your post. :)
I only updated the bios because I was originally experiencing these issues. It was a method to hopefully resolve them, which did not work. I was very careful, and the process was a success. I updated to the most recent recommended driver for my motherboard
from the manufacturers.
As for Auslogics Boost Speed, it is not running on my computer, as it is a piece of software I only have used to clean junk files (cache/temp) for a very long time now with no issue. I have also tried updating all of my drivers with success, however that
did not solve the issue either. I even rolled back my network card driver just in case with no luck.
I have not thought of disabling my audio driver yet, being how it effects far more than just my audio when it happens. My mouse is jittery/laggy as well when no sound is playing. But other tests have shown that it may be a network issue. Next time it happens
I'll temporary disable my network drivers to see if that causes the issue to clear up.
I will be sure to mark answers which help appropriately. Thanks again! I should return with the information requested from Zigzag's wiki within 2 days of on-time, when this happens again. -

Audio interupts/ISR/Dpc interupts and hard pagefaults
I seem to be getting stutters/freeesin my audio (and my computer in general). This problem is system wide and it started after i upgraded to windows 8.1 pro from windows 7. I did some looking around which lead me to this program LatencyMon which could help
identify the problem. seems like svchost.exe might be the main source of the problem but i dont know how to fix it.
I updated my network drivers already to the latest version but the problem persists. Below is the results posted.

This computer is VERY clean and has no anti-virus/firewalls/software
All drivers are updated (I'm not sure if the BIOS is updated yet)
SO far from research I've change my SSD to AHCI from IDE after doing some registry changes. MADE IT SO MUCH FASTER not why the original builder of the computer didn't do this in the beginning
I've disabled power setting on the WIFI adapter
When I disable the WIFI it seems to fix the issue but I NEED WIFI - I can't find anywhere online that explains if buying a new WIFI NIC would fix this?
I tried to run in command 'verifier' and an option to select all drivers on the computer - It made me restart but after that it crashed and needed to be set back to a restore point???So I disabled the WIFI card and hooked up directly to the switch and I'm not seeing NDIS.sys coming up as latency and after light testing it appears I'm not freezing up for the second or so randomly.
I think I"ll buy another WIFI card and see what happens.

Problems with hardware acceleration
Hallo
I have big problems with hardware acceleration in flash player. What complicates the problem is my laptops manufacter note here:http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-69684
so I'm accualy confused - is my laptop defected or the source of the problem is in flash player engine.
In to to point: I can't play some videos, because my video adapter/driver is restarted during watching and after it happens - flash plugin doesn't work anymore (until browser is restarted).
I have flash player in version: 10.2.154.25
Nvidia driver: 260.99 (with newest situations is not much better, I tried newest WHQL certified driver but I didn't work perfectly)
Hardware: Lenovo ThinkPad T61, core2duo 2.1Ghz, 3GB RAM, NVIDIA Quadro 140M NVS.
And here's video showing my laptops behaviour:
http://www.youtube.com/watch?v=QrXJCcWV2Sk
Notice also screen blinking (and audio stuttering) before video adapter is restarted.
Is it flash fault or hardware is defected?I got my laptop with replaced systemboard today.
Unfortunately the problem is still present. In the meantime there was Flash update released (10.2.159.1 for IE) so I also tried to install newest version - but it didn't help.
Having systemboard replaced, flash updated I still have screen blinking, video adapter restarting and NOT smooth playback using hardware acceleration.

Changing Monitor Frequency of a second one
Hi Everyone!
I'm working with my new arch system on my notebook and I connected my widescreen monitor LG Flatron L192WS 19', and It needs to be set with a frequency of 70 instead of the default 60 (because if not, the screen is a little out of place and I can't see the window border when a window is maximized). I have the gnome3 desktop, in the version 2 I had the option to set that on the monitor preferences, but it doesn't appear on the display preference in gnome3. How can I achieve this?Hi Hamza,
a second option would be to do it with custom VBA.
1) disable variable merging
2) disable the second query in the inital start
3) execute the 1st Query
4) with the "after redisplay"-event you catch the point after the first Query was done
5) with "SAPGetData" you can crap the information you need
6) with "SAPSetVariable" you can set the value to the second Query
7) with "SAPExecuteCommand,Refresh,DS_2" you can refresh the second Query as well
that should help you
Regards

Add EP-userid to BSP app as (URL) parameter
Hi,
I've created a default BSP-iView (via com.sap.portal.appintegrator.sap.BSP) and try to pass the EP-userid as an extra parameter, without any result so far. I've checked several SDN posts, but didn't help (or I didn't understand them).
In the properties of the iView I've tried to edit the following:
Application Parameters : user=<User.UserID> or
Parameters to Pass from Page Request (for URL isolation) : user=<User.UserID>
I need to pass the EP-userid, because the BSP app. is called with one user (user mapping for a specific Group/Role for the backend system) and is not able to distinguish the logged on EP-user.
Where did I go wrong?
Any suggestions how to solve this issue?
Best regards,
Markin the application parameter of the BSP iview pass
userid=<User.LogonUid> or
userid=<User.UserId>
and in the BSP application have a page attribute called userid with auto check box checked.
within BSP application now the variable userid will have portal logged on user id.

High DPC ion W8.1 leads to cutouts and distortions in sound
Hi guys, not sure if this is the correct place to post this.
I'm having major issues with the DPC on my computer.
Before I installed any programs and after on w8.1 i have been having audio drops and cutouts, after installing sound drivers and the Nvidia drivers the problem persists. I checked on LatencyMon and found that the "culprit" is ntoskrnl .exe which I
find weird.
I'm running on a pretty old customized computer:
Motherboard: GigaByte G41M-Combo Ver 2.0
Display card: Nvidia Geforce 630 GT 1GB
RAM: 8GB
My sound card is in my Motherboard.
I'm adding the Latencymon log below.
Thanks in advanced :)

Tree Table buttons displaying twice
I have an issue in ADF applicationsTreeTable button bar, If I select a row, button's area shuffles and we can see the button twice. This would be replicated only for the first time, On save/reload, it will not reproduce. If I clear the cookies and restore the page, this issue reoccurs. Please suggest some ways to avoid this. I have a selection listener, on select I have some if else conditions, based on that, I am disabling & enabling the buttons.
Hi,
Have you got any solution of this issue as I am also facing similar issue.
In my case I am enabling disabling the delete icon based on certain conditions. In the initial load of the object icons are getting disabled as expected but later if I add any new node in tree table and delete it the code will written the correct value of the disable variable but the icon will not be disabled.
Any inputs will be appreciated.
Thanks. -
Crackling/Popping sounds on Windows 10
Hello everyone. I have recently upgraded to Windows 10 from Windows 7 (the problem I am about to say never occured on Windows 7). When listening to music, I now hear popping/crackling sounds. I use my headphones to listen to music but I checked using my speakers and the same problem occurs. My PC info is:System Manufacturer: Hewlett-PackardSystem Model: HP Pavilion dv6 Notebook PCSystem Type: x64-based PCProcessor: Intel(R) Core(TM)2 Duo CPU T6600 @ 2.20GHz, 2200 Mhz, 2 Core(s), 2 Logical Processor(s)Installed Physical Memory (RAM): 4.00 GB I have checked DPC Latency ( http://www.thesycon.de/deu/latency_check.shtml ) and there does seem to be a problem. The latency spikes very often. The latency that I always have is between 1000-1500us but it spikes very high. For some reason, right now it says my current latency is 1192us but my maximum is 908,300,885! This does not seem normal! I don't know how to fix it! Has anyone else heard something like this and does anyone know a fix? On device manager under "Sound, video and game controllers" there are two drivers. I have used Device manager to try to update the drivers but it is saying that I have the latest version for both.1. IDT High Defintion Audio CODEC2. Intel(R) High Defintion Audio HDMI Thank you.
Hello everyone, this is an update on my issue. So I just tried uninstalling the IDT High Defintion Audio Driver, rebooted my computer and reinstalled the IDT High Defintion Audio Driver and I have no luck. I can still hear the popping and crackling sounds. I thought I'd share some information on this fourm. I just did a DPC Latnecy test (from LatencyMon) with nothing running but the test for 2 minutes and this is the report I got. If anyone either from HP or other people can assist me on my issue, I would very much appreciate it._________________________________CONCLUSION:Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.Process with highest pagefault count: ns.exeTotal number of hard pagefaults 1906

How to get Error Msg from A step in TestStand into a variable (with Record Result disable)
I have disable "Record Result" in a step (action) that call a Labview VI (Minimise memory usage during long run).
But I want to capture the error msg and put it in a local variable (locals.log).
So in the "Post Expression" of that step, I add:
locals.log = step.result.error.msg
But it always an empty string, Is the post expression executed when the there is an error in the step ?
So How can I capture it ?Hi,
The trouble is that when a step errors, the Post Expression doesn't get executed.
Try using one of the Override callbacks - SequenceFilePostStepRuntimeError, ProcessModelPostStepRuntimeError or StationPostStepRuntimeError.
There is an example in the Examples\Callbacks.
The Step properties are passed as a parameter to the callback so you can get the error message and do your logging.
Hope this helps
