PIC32 and RS232 Issue

Hi everybody i'm new in labview, i've a problem with my two LabView interfaces for RS232 comunication trough PIC32 and PC.
My purpose is to visualize in 31 text boxes a series of data transmitted from PIC.
The data format transmitted is SGL 32bit for 32 total data (128byte) (the first array's location contain the start string for synchronize the data in rx), before the transmission, I split every array's location in 4 byte and then I transmit them serially LSB first.
My two labview interfaces are GUI1 and GUI2, the results for both is the same.
Some times the received data are correct (all the text boxes are correct filled) and other time the data are wrong (are visualized 0s and casual values).
The issues appear with the USB to RS232 converter and the RS232 cable on Desktop PC.
Boundrate 115200 bps.
Any suggestion? thanks everybody

If you believe the issue is a hardware issue, why are you posting on a LabVIEW message board?

GPIB and RS232 communication problems

I've been having several "interesting" problems with GPIB and RS232 communications in LabVIEW VIs. Some I'll mention at the end for curiosity, but right now I'm facing a rather big problem. I'm essentially self-taught at doing LabVIEW (using 8.5.1 right now), but by now I've had a lot of experience as their either has not been any drivers or pre-made VIs for the instruments I've needed or I've not been able to get the available drivers to work and had to write my own anyway (such as with the HP 3458A), but nothing seems to be working right now. I'm not at work, but we typically find forum sites blocked anyway (I can't even download the NI drivers at work since they house them on a ftp server, go figures) so I can't give the VI itself (it wouldn't be easy to get approval even if I could) so the best I can do right now is in words describe everything I've tried. I will be happy to post follow-ups of specific details if I can if they would be helpful.
I've been working on a routine to read data from an MKS 670 Signal Conditioner/Display with a MKS 274 Multiplexer with 3 connected MKS 690A Baratrons. Previously I've worked on programs using other older displays and the analog outputs which were being read by a DAQ card, but for a new project it was decided to try and just read the data directly. I first worked with a unit with just an RS232 Serial Port which I managed to get to work, but had so much problems with garbage readings and having to add checks and re-reads that by the end no matter what delays I added between each reading and how simplified the command routine down to just 2 sequences and the read that it took at least 10 seconds to get 1 reading from each channel.
Figuring maybe it was a limitation of the serial communications for these instruments I tried to re-work it for a unit with a GPIB port with which I'm actually much more familiar. The problem is that I cannot get anything at all from the unit through GPIB. Everything even the bare-bones built-in GPIB CLR function times out with no response from the instrument no matter how long I set the timeout limit and it also freezes the entire GPIB bus as well. It isn't a waiting issue as it freezes on the very first command. The GPIB initialization function seems to work (I typically find this to be unnecessary), but the instrument itself doesn't even respond with a status code. I've also tried just the basic GPIB write functions with even just passing the <cr> and <lf> characters as well. In Measurement and Automation Explorer most of the time the instrument won't even appear when doing search for instruments and when it does it shows as not responding to the *IDN? command (yes I've messed with the EOI, EOS, etc settings and I've even changed the GPIB address even though when it gets this far it confirms that I have the correct address) and even tried manually doing the *IDN?, *RST, and *CLR commands even with <cr> and <lf> characters which the manual for these units clearly states are compatible commands and NI SPY and everything show no response at all. I've tried 2 different GPIB units, 3 different computers including several that are not online and haven't been updated for a while, and using older LabVIEW versions, extensive re-booting and resetting of computers and devices and still nothing. I'm using an NI GPIB-USB-HS GPIB to USB adaptor which I've used extensively on other systems and even re-connected to those systems and everything worked fine. When I hooked up equipment that I knew was working, it would either freeze the entire GPIB bus until well past whatever timeout setting I set at which point all the instruments would appear, but none responding to *IDN? queries or nothing would appear at all, or if I manually turned it off when frozen the other instruments would work and most even respond to the *IDN? queries. The same goes for both of the GPIB instruments of this type that I tried and again for different versions of LabVIEW, difference computers (all Windows XP though), and every GPIB configuration setting I can find to mess with in every combination.
Any thoughts or suggestions would be greatly appreciated. I've had all sorts of weird problems with equipment and LabVIEW (you've got to love undocumented design features) that have frustrated me before, but I've never had an instrument never respond at all especially a GPIB one. Getting garbage yes, no response at all, no.
The side side issues I'm just mentioning as they may be related, but I'm really interested in the above as I have working solutions for these:
One I've had is with a Hart Scientific (prior to being bought by Fluke) 1560 Black Stack that would continually stop responding to GPIB commands when on a continual read function taking readings just every 4 seconds with 250ms between each GPIB read or write command but for up to hours in total and the times it stops responding are random as far as I can tell. I even started sending the *RST command before and after every read or write command and still it freezes. The only thing is to manually turn it off and then back on or manually go through the menus and manually trigger the GPIB reset routine at which point it immediately starts responding. However, when I got sick of having to babysit it and just decided to try the RS232 serial port (as that is all it has without the extended communications module) it works fine no problem and I can even get readings slightly faster from it. Using a Hart Scientific 1529 Chub-e it could give me data on all 4 channels every second without problems. I just find it a bit odd.
When I couldn't get any of the HP 3458A driver packs to work to even give a single measurement reading and just made my own using basic GPIB read/write commands using the programming manual I still have a few interesting problems in randomly when reading off the full possible 256 bytes on the bus and clearing the bus I often find garbage partial readings on the bus every now and then. I've added a few routines to do some basic checks, but it is annoying. What is really weird is when just doing basic DC Voltage reads the "-" sign will randomly be dropped from some readings (started as about 1 out of every 5, down now to about 1 out of every 10). Fortunately I'm taking several readings and averaging and taking the standard deviation with limits on the deviations and basically added a routine to say if there is even 1 negative number take the absolute value of all then make all negative, but again I find it weird.
Thanks.

Greetings Leif,
I understand you have completed extensive troubleshooting techniques to pin-point the problem with the GPIB communication. To begin, I want to ask you a few questions to help me understand your set-up and the issue at hand.
1) Is the NI GPIB-USB-HS cable the one which cannot communicate with your instrument?
2) When using the GPIB-USB-HS, does the GPIB interface show up in MAX?
3) If yes, does the instrument appear in MAX after scanning for instruments (from what I understand in your issue, it does so in an intermittent manner..)?
4) What driver version of VISA do you have installed in your computer?
5) Are you able to communicate to the same instrument using another GPIB cable?
Thank you for trying out some of these steps again, but we want to make sure we rule out other aspects in the systems which might be affecting the GPIB communication.
As for your other issues, please post seperate threads for each so we can help you accordingly. Thanks!
Sincerely,

Failed Hardware Scan and other issues E440

Hi all,
This is probably more rant than anything, but I wanted to give a heads up to others too.
I have a ThinkPad E440 that is a year old. From the very first time I turned it on, there have been issues. The first hardware scan (via Lenovo Solution Center - LSC) showed a warning for the Intel Dual Band Wireless-AC 7260 Local Connection Test. There were also tons of System Events that always show up in the "Configuration History" part of the LSC. You can look at the calendar and tell exactly which days I used the computer because there will be System Events generated each day. Things like app crashes and failed drivers.
In July 2014, I got the first warning for the 16 GB SSD - the SMART Short Self-Test. By February this year it showed as failed for each hardware scan (these were initially set up to run monthly).
Also the whole time I've had it the touch screen would just stop working at some point and I would have to reboot to get it working again.
I finally called Lenovo on March 30th, before my warranty expired. When I called that time, I didn't realize the hard drive failure was the SSD. So they sent me a new 500 GB drive. I also added the other things into the case when I talked to them. For the wireless issue they suggested making sure the driver was up to date. I did this and let them know when I called back that it was up to date and still having the warning. So I called them to tell them to tell them about the wireless and also that I realized it was the SSD having the failure, not the main drive. The first case had already been closed even though none of the other items were addressed.
So they opened another case (this is #2). They said to mail them the laptop since the wireless issue would probably be on the board and it wasn't something I could fix myself. They sent a box with a prepaid overnight shipping label. I was very sick for a few days so I sent it back to them on April 10th (a Friday). Via UPS I saw it was delivered on Saturday. Work was performed on it Monday, April 13th and sent back to me that very day. I received it on April 14th. This part of the service has been excellent - very fast response.
Being in IT, I included a letter with the laptop that outlined the issues that should have been in the case. I also printed the hardware scans and what the system events looked like.
When I got the laptop back, the sheet inside said they had replaced the Speaker because of Distorted Sound. This was not even on the list even though I had noticed it. I didn't even power up the laptop before calling them again - yes, I was furious! Plus our power was out...
So this was noon on the 14th. They opened case #3 and sent me ANOTHER BOX so I could send it back.
After our power came back on the 15th, I powered up my laptop. I opened the browser (I have it set to restore the previous session) and there was a sexually explicit video on YouTube. I opened the other browser and there was a different video on YouTube. So this person was watching YouTube instead of fixing my laptop. I looked through both browser histories and there was quite a bit of activity while my laptop was at the repair center... I ran the hardware scan - still failed and a warning for the wireless. They really hadn't done anything.
I also found two pictures of the repair person in the recycle bin...
So I called back. I was LIVID! They opened another case (this is #4). And sent me ANOTHER BOX. I finally learned the other day that once a case is opened, it cannot be edited or added to at all. Instead, they close the other case and open a new one. I guess their turnaround time for closing cases is excellent! I've never seen a system like that - and I've used a lot of them.
I got a really nice, patient fellow on the line. He took all my info (again). I emailed him the pictures, screen captures of the YouTube videos, the letter I had sent - everything. He entered as much into the new case as he could - he talked to one of the supervisors to make sure he did it right. Somehow he flagged it so that the laptop would get more attention (time) at the repair facility. He also opened a separate case (an escalation ticket?) for a supervisor to call me regarding the person's conduct at the repair facility. He said they would call me that day. (It's now the 25th and I've never heard from anyone)
So, he sent me ANOTHER BOX. I've built up quite a stack of them.
Our power was out AGAIN from the 17th through the 19th (don't get me started).
I noticed a hardware scan had now gotten a failure on the main hard drive. So I called them on the 21st to add this to the case before sending the laptop back. The girl said they can't add anything to an existing case or edit it at all once it's opened. She would have to open a new case and SEND ME ANOTHER BOX. I told her to forget it because I was ready to send it in and didn't want to wait for another box. I also asked for a status on that "escalation case" where the supervisor was supposed to call me. In order to do this she, yes, wait for it, had to open ANOTHER CASE!! So they would know I wanted a status. I'm completely dumbfounded.
So I sent it back on the 21st. This time I practically wiped it. I had already removed all my files the last time, but I had left my bookmarks and browser history intact. I set up a guest logon with admin privileges. I updated my letter and printed off more stuff to include with the box. On one sheet I had only the case number, the serial number and machine type. On another sheet I had "DO NOT SEPARATE THIS PAPERWORK FROM THE LAPTOP" and the case number. I put this sheet on top (The guy on the 15th said my letter and stuff may have gotten separated from the laptop once it was delivered to the repair facility). I used a ton of staples so it would all stay together. I included in my letter the failure on the main hard drive and asked if they could look at it. I wrote about having to open a new case if I wanted to include it.
They received it on the 22nd. A nice gentleman from the repair facility called me that day asking about the password. that. was. written. on the sheet they have you fill out. I told him what happened last time and also mentioned the hard drive failure and asked if he could look into it. He said they would.
I received my laptop back yesterday morning.The sheet that came with it said they had "replaced the following parts to complete the repair of your laptop."
Part Description                                           Symptom
IMAGE                                                             Replaced due to engineering change
System board                                                 Network card error
Hard disk drive                                                Network card error
ECA-WIRELESS                                            <no symptom listed>
There was also a sheet saying they had installed a factory preload of software and I needed to install Lenovo and Windows updates.
When I booted it up, the first thing I noticed, in the lower right corner was:
Windows 8.1
SecureBoot isn’t configured correctly
Build 9600
I ran a hardware scan. Well, I tried. It stopped part way through and said it finished successfully but most of the tasks showed up as cancelled. I tried to run it again - issues - rebooting ensued. It said the LSC wasn’t available and that I should try again or reboot.
Tried several times. Then got what I guess is the new BSOD - kinder, gentler:
Your PC ran into a problem and needs to restart. We're just
collecting some error info, and then we'll restart for you. (xx% complete)
If you'd like to know more, you can search online later for this error: DRIVER_CORRUPTED_EXPOOL
Even though the LSC said my Lenovo files were all up to date, I ran the Update. And first I had to download a new version of Update. Then I downloaded all of the Lenovo updates and installed them (there were quite a few). The BIOS update failed. While I was doing the Lenovo downloads, I got a light blue screen but no text (I was out of the room so I'm not sure what happened). Did CTRL-ALT-DEL and it shows only IE and Task Manager as applications that are running. Could not “Switch to” IE. Hitting window key to go to start didn't do anything. So I had to restart.
By 3pm yesterday there were 34 system events in the configuration history.
I ran the hardware scan again after I updated the Lenovo files, and you guessed it! Failure on the SSD (SMART Short Self-Test) and warning on the wireless. Nothing had changed. Except hardware scan is acting different than it did before I sent in the laptop for repairs. When it finishes, it instantly closes and just shows 100% complete. When I click on "see last results" it shows a screen called
Log Information,
Canceled 04/24/2015 n:nn pm
You have not done a hardware test on your computer
And the calendar in LSC only shows the very first hardware scan I did on Friday. Even the hardware scan screen shows the date and time of the last scan. It also shows the error code. In order to see exactly what is failing, I have to sit there and watch it very closely and snap a picture of the screen as soon as the error (or warning) shows up.
When I would try to run Windows update, it would hang up PC Settings. I couldn't even kill it using task manager because it didn't show up as a task. During this, I got a flag saying the firewall wasn't turned on. I tried to turn it on, but clicking on Turn on Windows Firewall didn't do anything. I tried to setup my Microsoft account but that just hung too.
I ended up running Windows Update FOUR TIMES to get all the updates installed. Every time I ran it, it said "Done!" and I would run it again and more would show up. The last time was this morning.
At some point, the error about SecureBoot went away.
Then, I created a bootable BIOS update disk. Following the ReadMe instructions, I went through ThinkPad Setup and verified several values. Of note:
Secure Boot was DISABLED. According to the ReadMe file, this should be ENABLED in Windows 8.1. I enabled it.
Under Startup/Boot, according to the ReadMe that came with the BIOS update, UEFI/Legacy Boot is supposed to be set at UEFI Only for Windows 8.1. Mine was set to "Both". I changed it.
In Startup, OS Optimized Defaults was DISABLED, even though it says right there (and in the BIOS update ReadMe) it should be ENABLED to meet Microsoft Windows 8 Certification Requirement.
After these updates, I flashed the new BIOS.
Then, I ran hardware scan again...
Now I have TWO failures on the SSD: Random Seek Test and SMART Short Self-Test. Great.
In the Event Viewer (that I recently discovered), it says my disk has a bad block. It just says The device, \Device\Harddisk\DR1, has a bad block. I assume this is the SSD...
There are 867 events in the event viewer - Critical, Error, and Warning...
Fifty-two of these are from October 7, 2013 - before my little laptop was a glimmer.
The rest are from when Lenovo had it and yesterday and today.
64 of them are the disk error.
341 are from DeviceSetupManager. 65 of those are from failed driver installs. 69 are for not being able to establish a connection to the windows update service. 64 are from not being able to establish a connection to the Windows Metadata and Internet Services (WMIS).
3 times it's rebooted without cleanly shutting down
60 of them are from Service Control Manager and say The TDKLIB service failed to start due to the following error: The system cannot find the file specified.
One of them says {Registry Hive Recovered} Registry hive (file): '\??\C:\Users\Default\NTUSER.DAT' was corrupted and it has been recovered. Some data might have been lost.
16 are warnings that various processors in Group 0 are being limited by system firmware.
12 say the certificate for local system with thumbprint <bunch of hex numbers> is about to expire or already expired.
108 are warnings for failure to load the driver \Driver\WUDFRd for various devices
16 are application errors
One is for the computer rebooting from a "bug check"
15 are for name resolutions timing out after none of the configured DNS servers responded.
10 are for SecureBoot being disabled.
14 for services terminating unexpectedly
15 are for WLAN Extensibility Module has stopped
61 are for applications not being able to be restarted because the application SID does not match Conductor SID
12 are for activation of CLSID timing out waiting for the service wuauserv to stop
So, I'll call them on Monday and open. a. new. case (#5?) - but really 7. And get A NEW BOX.
I'll keep you updated!

Hi amycdero and welcome to the HP Forum,
I understand that you are having scanning and printing issues after upgrading to Mavericks OS X v10.9.1. I will try my best to help you resolve this issue.
In this document for Mac OS X: Scanning Software Does Not Open or Stops Responding are steps the may help you with your scanning issue.
This document for Fixing Ink Streaks, Faded Prints, and Other Common Print Quality Problems should help with the streaking printing issue.
I hope this information is helpful. Please let me know.
Thank you,

Battery, heat, and ringer issues

I recently purchased the Iphone 4s.. this is my first iphone
I did the update that Apple sent out to help the battery and it seems like it worse then before the update?? My phone has been off the charger for 45 minutes, I sent 1 text message, and had 1 phone call. The percentage is now at 87. It the last 2 minutes i have watched it go down 2%? Is this normal? Also, the phone gets REALLY hot...
If not, what do I do now??
Also, I keep missing phone calls because I don't hear the phone ring... but the ringer is all the way up..
Any help will be greatly appreciated!!

1. Connect your Z10 to the wall outlet charger for an hour and then with the Z10 powered on, and with it STILL CONNECTED, remove the battery for a minute and replace. This will normally reset the the on-device battery meter and allow the charging status and percentage to show more correctly.
2. Orange is your tech support contact and any issue which they cannot resolve, they should escalate up to BlackBerry tier two tech support, or you should ask/demand that.

New Airport Extreme and iPhone Issues

I've had the networking day from ****. I previously had a 3rd Gen Time Capsule at our restaurant, connected to a Cisco 26port gigabit POE switch and Comcast digital voice and internet. Over the past few days, employees have reported trouble accessing the the Wifi network. After several restarts and firmware upgrades (including the dreaded "firmware problem" to fine update), nothing worked. I changed channels, back to auto, back to specific channels, back to auto. Made open guest networks. Nothing worked consistently. My iPhone might connect and my friend's might not. Nor his laptop consistently. Our Axis network cameras might take a bit extra time to connect. All quite random and quite frustrating.
So I swap out an older Airport Extreme (4th gen I believe) using the same configuration as the TC (Time Capsule). It works fine, except for the last port not working as expected. No matter, I plug the mac mini into the Cisco switch and off we go. Nevertheless, I'm still told we are suffering random Wifi issues. So I buy a brand new AE (5th gen) today to replace that one. Should work like a charm I thought. Right....
Several hours later, I finally have the new AE working, but only after doing several hard resets/factory restores, the works. For some reason, the mac mini could not successfully update any of the connected AEs - whether connected directly into the same AE, or if the Mini was connected to the switch. Nothing worked. Every time I tried to update the AE, it would hang and force me to unplug and plug it back in. It would also never save setting changes. I finally resorted to a friend's macbook to be able to restore it successfully. And once that worked, the mini was able to update the AE flawlessly. Our Point of Sales (POS) machines connect fine, our cameras connect fine, wifi printer connects, and the mini connects, and everything has internet.
Except my iPhone 5. Of course. It gets a signal fine (full bars). It gets an IP address. But I can't surf the web. Or download email. Or iMessages. Anything. No internet access. I try hard restarts on my iphone. I try assigning IP addresses by MAC address. I try resetting the AE. I try renaming the WiFi name. Nothing. I can make a guest network that works (on a different IP table, btw - 172, not 192.) But other than that, no access. Grrrr.
So I have a "working" AE router where some devices successfully connect (through wifi and ethernet) and some dont' (wifi iPhone). My iPhone connects fine to my home TC. So shouldn't be anything to do with that. But I'm at a loss. I'm going to go back and restore everything and power cycle everything tonight or tomorrow night. I don't know if that will help, but it's worth a try. Lord knows it feels like I've tried everything else.
Anyone have any good ideas of where to start besides voodoo dolls and baseball bats?

I took mine back, because I was having these very same issues. We use contivity too. I was able to connect only to one of three of the servers we manage (in Europe). I couldn't connect to the servers in Asia or here in the USA.
Replaced the Airport Extreme with my trusty old d-link 624, and no issues connecting to any of the three hubs.
Otherwise, I liked the Airport Extreme, and I'll consider buying it again when and if they address this VPN issue. I work at home so its obviously a "deal breaker" for me.

IQ826t Restart and Heating Issue

One thing I definitely do not like the HP's support especially when they will not allow us to buy a 7 Upgrade from Vista nor will they support something (even when I find their glitches and they admit after telling me it was just the OS).. On Repair work, I had to ship it out and this will be my 2-3 time to do repair on this PC in the past 3 years (and I have to wait a week for the repair to be done...)
Besides that, IQ826t, Win 7 Ultimate SP1
All Drivers are up to date with HP website (utilizing Win 7 64 bit drivers and Firmware is up to date). AVG update/scan (no issue - confirmed even rootkit).. Malwarebyte - Scan and no issue
Disk Cleanup, Disk Defragmentation done on a monthly and quarterly schedule
Biggest Issue:
I am getting a crash with Win 7 0x124 Stop Error Message (happens periodically and even after a reboot)
Never had this issue until May and the upgrade to Win 7 was done last year with SP1 update done on March (so it is not an issue with the OS as HP support personnel seems to think... I proved them the issue with Windows Update History, The Bluescreen error code on my error code reader).. This machine under warranty and I had issues with it constant (even in Vista)
They state that it is the OS.. Again, if that was the case, I would think it would happen right away like my Toshiba on SP1 upgrade... That was not the case in the matter. I have a firmware reset (default settings) and the issue persist..
The Error Code relates always HAL.dll or ntoskrnl.exe
One if hardware compatiblity and the other is an OS kernel exe file.. And this usually checking knowledge base relates to hardware failing due to 1) Compatibility (which HP website confirms is not the case) 2) OS corruption (which is not the case checking on safe mode and this happening STILL 3) Heat Issue (which I believe is the issue and was been documented on the Internet
What I am noticing is the unit is extremely HOT (vent is almost burning when it has been off and just turned on).. I wonder if the hardware pieces are literally melting to destruction since I can't just open it up (they state it will void my warranty)
The Symptoms before the Crash (happens any time.. Even right after a power up)
If you are playing audio or video, you will start to hear jitters and sound seems to echo itself .. Video would start to lag and become choppy.. Systems start to slow down and things seem to run very slow.. I have seen the power light on the PC start on but the touchscreen just go black (will not restart sometimes)..
Minor Issues (but could be related)
1) When running PC Hardware Diagnostic, they will come up with an error code in the past and that was warranted for a motherboard replacement (of course, they ship the box to the wrong location and I was in the middle of my wedding so I get to it now).. It was pertaining to PCI Express Status ICH9 PCI Express Root Port where it will generate an error code... Now, running the diagnostic... I will not get any error but PCI Express Root Port 3 & 5 do not show up on the diagnostic... Wouldn't that obvious show something that is a problem when there are 6 ports (which on the previous diagnostic that I can't grab past logs shows that). That is not warranted for a warranty work? Just a note, I got the fail test code (which was intermittent but keep happening and the tech support would not look at previous case.. Port 4 failed and a fatal device code)
2) Blu-Ray player will not run and their answer is that it is your Blu-Ray until they realize that I ran it on 3 different Blu-Ray player standalone, different Blu-Ray, and confirm DVD will work.. They still think it is a software issue until they can't deny my point when it will not read the Blu-Ray no matter what (they took control and confirmed it).. They believe the HP SmartDVD software was failing because of Win 7 and not Vista (even when I downgrade and confirm it works, I stated the software is the issue... Lone and behold, 2 months later they had an update that they refuse to admit I was RIGHT on the matter and done 15 hours of troubleshooting that they were wrong about)
3) Wireless Keyboard and Mouse lost connectivity even if the battery is not low... Just stop typing or omit letters.. This is considering the keyboard is literally in front of the touchscreen
4) Touchscreen is sensitive when it wants to be but won't in other... Constant issues there
This is why I have so much issue with support.. They seem to show that they will do anything to deny the issue.. Heck, I am a computer technian calling on the issue.. It ain't like I didn't troubleshoot on the matter... But they think we are all morons and when I prove them wrong, they will use any excuse to honor warranty... That is why it is amazing..

Look in your Settings > App Manager.

Just updated to IOS 7 and two issues: First when I connect my iPhone to my computer I get this error message:itunes was unable to provider data from sync services".

Just updated to IOS 7 and two issues:
First when I connect my iPhone to my computer I get this error message:itunes was unable to provider data from sync services". I'm not sure what this really means...
The second issue is when I try to select "Manually Manage Music"
The iPhone "My iPhone" is synced with another iTunes libary on "MY-PC". Do you want to erase this iPhone and sync with this iTunes library? An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library."
So... I don't want to do that, but I do what to be able to Manage my music. I'm not sure what it means by being synced to another iTunes unless it means to an older version of itunes?
Anyone have any ideas?

I cannot address the sync services error right now, but the error that you receive when you change from sync to manually manage music is what happens when you change. Once you change to manually manage music, it erases all of the music and will only put the music that you want on the phone, content that you manually drag over to it.

PO number and material issued against this PO for subcontracting

How to know the link in between the PO number and material issued against this PO for subcontracting.
I have checked that PO history is not getting updated.
Thanks,

Hi,
We have 2 different scenarios where you can post a goods issue to Subcontract Venodrs.
Scenarios 1: You can post the goods issue against a subcontrac vendor with out referencing the Subcon PO from ME2O, at this stage we will be knowing what is the stock at subcontract vendor but we will not be knowing the issues against which and how much Quantities are posted.
So when we are post goods receipt, then we will come to know the consuption quantities.
Scenario: 2, If we use the delivery concept then we can track the goods issues against the subcon POs.
If you really keen to track the material issued to Subcon vendor against a PO so better use with delivery.
Thansk,
Satya.

OS 10.4.10 Update Causing Audio Popping (AND HUM) Issues:

OS 10.4.10 Update Causing Audio Popping (AND HUM) Issues:
The problem on my Intel Mac mini with external Klipsch speakers (two mid-range/high and a subwoofer) is REAL obvious as the system emits a hum like a Spinal Tap amplifier turned up to #11 when 10.4.10 powers down the audio circuitry
Then, if I play a song in iTunes, it first pops and the hum disappears right before playing.
Quite annoying. I restored the mini from a recent backup to 10.4.9. Problem gone.
I'm glad I test updates on the mini before applying them to my Intel iMac 24. I guess I'll just hide & watch what happens before doing any more updates.
Here's what I sent to Apple tech support:
Guys/Gals (OS X Engineers):
Concerning the Snap, Crackle Pop Audio problem in the 10.4.10 update:
Please. Just do the right thing and fix the audio.
There is no need to power cycle the audio subsystem to save .0005 amps on the laptop line.
And then to make your Mac mini/iMac/other desktop users have to put up with it when using AC power is ridiculous.
Put the audio subsystem back like it was in 10.4.9 and let the laptop battery freaks looking for mini-amp savings get a "work-a-round".
Crikey!

Libby,
Backup is unable to make a restorable by Disk Utility backup. You can restore pieces of the software as outlined in my FAQ about backing up user data:
http://www.macmaps.com/backup.html
But to be able to restore a backup with Disk Utility, you need a cloning utility to have made the backup.
I suggest starting a new thread here, where someone else could help you out better:

First off, you'll get a wider audience who may be able to solve your problem. Secondly, responses to you won't confuse the original poster with solutions that don't apply to them. And thirdly, you'll know for certain whether or not a response applies to you.

Quality of Service and Jitter issues

I am having poor quality of service (36%) and Jitter issues (36ms). I called Verizon Fios technical support and was told that my connection is fine and that it must be a vendor issue. Only vendor I'm having an issue with is Verizon. If I can't get someone from Verizon that knows what QoS and Jitter is on the phone to help me troubleshoot this issue I'm going to have to cancel my service and find a provider that has someone technical providing tech support.

Fed up with speed and connection issues since exch...

Last Monday BT done some upgrade work at our local exchange. From that point onwards we have had speed and connection issues.
I use a Belkin G Router rather that the Homehub some that we can run a printer through it and that is plugged in to telephone socket via an extension. But before we blame any of that we have gone back to the Homehub2 so we could see the difference and there is very little.
We live in the countrside so broadband speeds are not great in any case. About 1.8 mg I guess but we have always had no problems. It was good enough for us and we could watch Iplayer.
I was getting fed up with drop outs and speed and yestereday an Openreach guy came out tested everything could not find any problems apart from speed. He made some calls and was told our band width had been capped. He had that removed and yesterday evening speed was a bit better.
Today just as bad again.

Hi Welcome to the forums
Your high noise margin will have a major impact on your speed
If you post the full stats from your router
For homehub – type 192.168.1.254 into your browser
Navigate to ADSL Settings or use the A-Z at the top right of the home page and scroll down to ADSL Settings and click on it
Click on More Details and then post the full results.
also post the full results from http://speedtester.bt.com/
Have you tried connecting to the test socket at the rear of the master socket
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
also you could try the hints given by poster RogerB in this link they may help http://community.bt.com/t5/BB-in-Home/Poor-Broadband-speed/m-p/14217#M8397
Then someone here may be able to help and offer more advice.

Goods Receipt and Goods Issue

Hi Gurus,
I am working on an interface where I need to work on a process that allows posting of Goods recipts and goods issue and for this I have been asked to create a custom transaction that will pull the data from the local file and replicate Goods receipt (MIGO) and goods issue process in Inventory Managemnt.
Can anyone out there please help me out how to approach this development and what would be easiest way to accomplish this task.
Help will really be appreciated.
Thanks
Rajeev...

1.   Create a custom report which get the data from input file.
2.   Populate the BAPI parameter with respective information and movement type.
3.   Call BAPI - BAPI_GOODSMVT_CREATE .
4.   Call BAPI_TRANSACTION_COMMIT.
For the custome report you can create transaction and execute.
I don;t have detail information - BAPI_GOODSMVT_CREATE with example. Better you search on SDN.

Nilesh

Cache and performance issue in browsing SSAS cube using Excel for first time

Hello Group Members,
I am facing a cache and performance issue for the first time, when I try to open a SSAS cube connection using Excel (using Data tab -> From Other Sources --> From Analysis Services) after daily cube refresh. In end users
system (8 GB RAM), for the first time, it takes 10 minutes to open the cube. From next run onwards, its open up quickly within 10 secs.
We have daily ETL process running in high end servers. The configuration of dedicated SSAS cube server is 8 core, 64GB RAM. In total we have 4 cubes - out of which for 3 is full cube refresh and 1 is incremental refresh. We have seen after
daily cube refresh, it takes 10 odd minutes to open the cube in end users system. From next time onwards, it opens up really fast with 10 secs. After cube refresh, in server systems (16 GB RAM), it takes 2 odd minutes to open the cube.
Is there, any way we could reduce the time taken for first attempt ?
Best Regards, Arka Mitra.

Thanks Richard and Charlie,
We have implemented the solution/suggestions in our DEV environment and we have seen a definite improvement. We are waiting this to be deployed in UAT environment to note down the actual performance and time improvement while browsing the cube for the
first time after daily cube refresh.
Guys,
This is what we have done:
We have 4 cube databases and each cube db has 1-8 cubes.
1. We are doing daily cube refresh using SQL jobs as follows:
<Batch xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">
<Parallel>
<Process xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ddl2="http://schemas.microsoft.com/analysisservices/2003/engine/2" xmlns:ddl2_2="http://schemas.microsoft.com/analysisservices/2003/engine/2/2" xmlns:ddl100_100="http://schemas.microsoft.com/analysisservices/2008/engine/100/100" xmlns:ddl200="http://schemas.microsoft.com/analysisservices/2010/engine/200" xmlns:ddl200_200="http://schemas.microsoft.com/analysisservices/2010/engine/200/200">
<Object>
<DatabaseID>FINANCE CUBES</DatabaseID>
</Object>
<Type>ProcessFull</Type>
<WriteBackTableCreation>UseExisting</WriteBackTableCreation>
</Process>
</Parallel>
</Batch>
2. Next we are creating a separate SQL job (Cache Warming - Profitability Analysis) for cube cache warming for each single cube in each cube db like:
CREATE CACHE FOR [Profit Analysis] AS
{[Measures].members}
*[TIME].[FINANCIAL QUARTER].[FINANCIAL QUARTER]
3. Finally after each cube refresh step, we are creating a new step of type T-SQL where we are calling these individual steps:
EXEC dbo.sp_start_job N'Cache Warming - Profit Analysis';
GO
I will update the post after I receive the actual im[provement from UAT/ Production environment.
Best Regards, Arka Mitra.

Change in PO Price after goods receipts and goods issue

Dear All,
Happy Holidays!! Wishing you a happy and fun-filled holiday season.
I would appreciate your input of the issue at hand. I support MM users in and Oil & Gas downstream company.
Issue
Purchase Orders are created using price estimates. The price of oil products fluctuates and we usually cannot get the exact price at the point of creation of the PO.
We use Moving Average Price (MAP) for stock valuation and so the price & quantity in the PO affects the moving average price.
We use price estimates to create the PO but when we receive the final price for the oil products from the Supplier, most times there is a significant difference between the estimated price and the final price. Usually, at this point, we have completed all goods receipts and goods issues against the PO and are unable to make changes.
We have an issue posting the invoice because the invoice value is significantly higher than the PO value. We also have an issue with the moving average price because it is understated as a result of this.
To reiterate, this is a summary of the issue:
At the point if PO creation ; Quantity = 10, 000 MT Price = $650
Later when final price is available; Quantity = 10, 000 MT Price = $715
Any advise on how to treat this issue, please? Your assistance will be truly appreciated.
Thanks

Hi All
For my client I have to map the similar requirement for material price which is subject to more than 15% fluctuation. The actual invoice price is having quite a huge difference.
Below are my limitations within which need to give a solution.
PO is subject to release strategy and Material is delivered over a longer duration of time. Hence there is problem to de-Release the PO everytime price is changed.
Since differnce is so huge, the same can not be settled during the MIRO.
Down Payments has to be posted hence PO has to be created with estimated base price.
Please suggest me suitable alternative options which will require no changes in PO and the price change also can be accomodated during the MIRO for Multiple goods receipts.

Extreme charging and syncing issues

Okay, so for the past few weeks I've been developing charging and syncing issues. The first third party usb cable worked for a while and after some point it begin to physically wear and tear, and wires were disconnecting. Needed a new charger, so naturally I went and got another one. However, it didn't work, and as a measure to see if it was faulty, I plugged in the old one and smelt smoke/a burn smell.
So, I plugged the new charger into an old ipod touch 2G and it charges and syncs just dandy. The 3GS is a particularly weird case here; as it will not charge while on. After letting it die, I plugged it in and got an empty battery indicator with a charging (lightning) symbol, and after a couple of minutes it powered back on, but still wasn't charging once ios actually booted up. Weird, right? If I could connect to windows I could restore it to remove the jailbreak, as using Erase All Content and Settings keeps the phone in an endless loop until I hard reset.
The kicker here is that it seems to only charge when it's off, as if its plugged in and you slide to power off, and turn it back on later, it will sometimes have a higher percentage. And, at the place I work, we have many iPads so I plugged it up to the iPad chargers and it worked with some of them, albeit slower then expected.
Is my phone not getting enough voltage or something of the nature? I have 3 wall adaptors, one apple, and two of them standard LG adaptors, and a third party usb cable that notably works for the iPod just fine. I've connected it to 3 different computers with itunes and the result was the same as if it was dead and plugged into the wall; enough power to boot to home screen then die afterwards.
The thing that get's me is when I hit Erase All Content and Settings and it's plugged, it makes a charging noise indication but only when I hit that reset button. If it wasn't for that, I would beleive it was a hardware issue. That, or I'm just trying to deny the phone's inevitable fate. I needed a reason to switch to the 4s, so maybe this is it. I don't like giving on on something without fixing it though so it's gonna bother me until I do.
Thanks for any suggestions or help!
