LIMIT question

Hello!
I've got one interesting question on OLAP DML. Assume you have dimension ARTICLES and one hierarchy with levels CATEGORY, SUB-CATEGORY, ITEM and one cube with variable SALES measured by this dimension.
question: how to limit ARTICLES dimension to all top 20% items in EACH sub-category based on sales?
I have tried to prepare a DML program with loop over ARTICLES dimension using TEMPSTAT PUSHLEVEL and POPLEVEL, but it seems that TEMPSTAT kills all PUSH in such loop.
Does anybody knows how to do it?
Thank you in advance.

You're right.. It was interesting :-)
I couldnt get it to work using just OLAP DML commands..

You can create a DML program and use the Limit function with Top N PERCENTOF based on expression to perform the needful.

How to Open the FailedFilesLog.txt File (statement), and How to Increase the 100 File Limit (question)

It took us a while to figure this out, so I'm posting this in case it's helpful for someone out there. Plus, I have a question...
DPM gave the following error for one of our file servers:
Description: The replica of Volume D:\ on <servername> is inconsistent with the protected data source. Number of files skipped for synchronization due to errors has exceeded the maximum allowed limit of 100 files on this data
source (ID 32538 Details: Internal error code: 0x809909FE)
Recommended action: Review the failure errors for individual files from the log file
\\?\Volume{8492c150-f195-11de-a186-001cc4ef89a0}\B1E9D373-2C03-464E-A472-99BC93DB1E2A\FailedFilesLog.txt and take appropriate action. If some files fail consistently, you can exclude the folders containing these files by modifying the protection group or
moving the files to another location.
So, how do you actually open the FailedFilesLog.txt file shown in this DPM alert? What is this path referring to? Well, this is the mount point for the protected server's replica volume on the DPM server, which is mounted under \Program
Files\Microsoft DPM\DPM\Volumes\Replica\servername\File System. Here you'll see the mount points for all of the server's protected volumes. However, if you try to open one of these mounted volumes
in Windows Explorer, you'll get Access Denied, even if you have administrator rights. (If someone knows of a way around this, please let me know). As a workaround, you can access this mounted volume in an elevated
command prompt. Steps:
Open an Administrator Command Prompt
Type mountvol <AnyAvailableDriveLetter>: \\?\Volume{VolumeGUID}
Example: mountvol m: \\?\Volume{8492c150-f195-11de-a186-001cc4ef89a0} Note that we're only using the first part of the path to the FailedFilesLog.txt
file given in the DPM alert, starting from \\? and ending after the
} character.
Next, type m: to change to the newly mounted m: drive.
Then type cd B1E9D373-2C03-464E-A472-99BC93DB1E2A This is actually a folder name so we're just going into this folder.
Finally type dir and you should see the FailedFilesLog.txt file. This file can be copied to another location where it's easier to use (i.e. in Windows Explorer).
Be sure to unmount this volume when you're done by typing mountvol m: /d in the command prompt. (Mountvol reference:
http://technet.microsoft.com/en-us/library/cc772586(WS.10).aspx.)
What a pain, eh? But at least by reviewing the FailedFilesLog.txt file you can determine which files or folders caused the sync to fail and thus take action accordingly.
Now, here's my question: Where is that registry key that lets me adjust the limit of 100 files that DPM allows to be skipped before it fails the replica? Hopefully someone out there will tell me. I know this can be done because Kapil Malhotra
said so in this post:
http://groups.google.com/group/microsoft.public.dataprotectionmanager/browse_thread/thread/a179fa30fb50c9b0/e9a348f2a9386063?lnk=raot.
Also, does anyone know what the internal error code 0x809909FE means in this alert? Knowing this my help us determine what caused these files to fail. Interestingly, in the FailedFilesLog.txt file, it gave a different error code next to each failed file:
0x80070002.
-Taylorbox

Thanks for responding, Fahd. So, just to be sure...
Do I add this registry key to the DPM server or to the protected servers (or both)?
In either case, the ContinueOnFailure key does not currently exist. So, I must create this key and the MaxFailedFiles DWORD value
manually, right?
Does the server in which I create this regkey have to be restarted for it to take affect?
Can the DPM alert for the 0x809909FE error event (for exceeding the limit of 100 failures) please be adjusted to provide a path to the FailedFilesLog.txt file
that actually works if you click on it?
Any ideas on why the 0x80070002 "File not found" error happened? The files on the server were simply created and then deleted. Why would such file activity lead to this error?
Thanks,
-Taylorbox

Temporary files and buffersize limit question

Hello,
I have two questions :
1. Buffer limit
Is there a limit for the buffer to return to a client. I have
a conversational service routine. If I want to return 50 record ( i.e. view structures
) my service routine hangs. If I do 10 records than it is ok. Is there a limit
size to return. Is there a parameter in UBBconfig to fix this.
2. Temporary files on conversational client / services
My service routine creates temporary files in the /tmp directory. Unfortunately
the mode for /tmp has 't'bit on so users can not delete files from other users.
The problem is I have a lot of temporary files in /tmp. Does anyone know how to
fix this or where can you specify not to use temp files or where can you specify
the directory to create tempfile. de name of files are /tmp/TUXxxxxxx where xxxxxx
is a random serie of characters.
Thanks a lot

Buffers that are larger than 3/4 of MSGMNB are sent through a file. The name is
generated with tmpnam(), so you should be able to specify a different directory by
setting TMPDIR in the environment.
The preferred solution is to not use file transfer, by setting your IPC parameters
high enough to pass all of your application messages.
If your service routine hangs, you should look at a possible application problem.
How are you packing the VIEWs into a buffer? Are you using embedded FML with
FLD_VIEW32 fields? That would be the best way.
Remember that VIEWs are binary structures that are unique to a particular machine
type. If you pack Views together into your own buffer format, and try to use them
on a different machine type, then they won't work properly.

Disco 4 OLAP dimension limit question

Hello!
Small question about Disco. Is it possible to do a limit on dimension simmilar to this:
limit dim1 to HIERARCHY DEPTH 4 SKIP 3 'ONE_TOP_MEMBER'
limit dim1 keep top 500 BASEDON SALES
The problem is that in Disco we can not limit Current selection if we are doing top/bottom query. It allows to select only full level of hierarchy but we need only several members of that level. Are there any other aproach?
Thank you in advance!

Time Capsule 50 Device Limit Question/Help

I have a Time Capsule and I understand they are limited to 50 devices. Well, I must have reached my 50 device limit, because I can not connect any additonal devices. How do I go about deleting past devices so newer devices can connect? I've done a reset, but that does not do it.

A full factory reset will.
The Factory Reset Gen1-4.
Unplug your TC. Hold in reset. and power the TC back on.. without releasing reset for about 10sec. When the status light flashes rapidly; release it.
Be Gentle! Feel the switch click on. It has a positive feel.. add no more pressure after that.
TC will reboot after a couple of minutes with default factory settings and will wipe out previous configurations.
No files are deleted on the hard disk.. No reset of the TC deletes files.. to do that you use erase from the airport utility.
Set the dhcp server time to 20min.. that will quickly recover the IP of any device that is no longer connected.
A gen3 TC btw is more than 3years old now.. mostly.. and will be unreliable.. it needs replacement.. they are not long life devices.

4 GB File Limit Question

I've digitised three clips into FCP. Clips are 1GB, 6GB and 13GB in size.
A freelance editor wants to transfer these files to his external drive so he can edit on his PC Avid. His drive is formatted as Fat 32. Am I out of options in transferring the two larger files because of the 4GB file size limit?
From the following link:
http://tinyurl.com/6q49vn
I understand that the editor will need to convert to a codec that his machine will be able to play. But short of having to divide the clips up manually or redigitize the clips in shorter durations, are there other options? He doesn't have a deck to redigitize the footage.
Thanks for the help.
John Lanza

Issue with that workflow...DVCPRO 50 Quicktime files captured via FCP will not work on a PC. Those codecs are only available to machines with FCP. So even if you can capture the files and get them to him in the native DVCPRO 50 format, he will not be able to see them. You'd need to transcode them into a format he could use.
What system does the editor use? YOU have the deck, why not loan it to him so that he can capture it on his system? Capturing footage in one NLE for use in another is unwise, and should always be avoided. because NLEs all have different ways to capture footage. QT, MXF, AVI, OMFI...

ITunes Match exceeded 25k limit question

Hi,
My iTunes library exceeded 25k songs, and so I went through and deleted quite a lot of albums - when you right-click an album though, it doesn't ask you if you also want to delete the songs from iCloud - I think from experimenting that I should have selected the individual songs instead - however, I've taken my local library down to 24k now but it's still saying my iCloud exceeds the 25k limit.
Any ideas on what I should do next - is there an option to manually manage my iCloud collection for instance?
Thanks
I'm on OS X 10.9.5, and the latest version of iTunes FWIW.

Hi,
This is a draft of a user tip I intend posting. Does it help?
"iTunes match has a limit of 25k tracks for tracks matched or uploaded. iTunes purchases do not count towards this limit.
Can you have iTunes match and an iTunes library with more than 25K?
Yes but you need to manage your library so that you keep matched and uploaded tracks below 25k. With iCloud status column added to song view (go to menu > view > view options and tick appropriate box), you can tell what has been matched, uploaded, purchased, ineligible, duplicate or waiting. You can also have a "Removed" status. Such files are ignored when match scans your library.
I achieved this by creating a second blank library - I signed into match and was able to view all tracks in iTunes Match. iTunes: How to open an alternate iTunes Library file or create a new one
I then deleted some tracks from this library - effectively deleting tracks in the cloud. They were not deleted from you hard drive and will still appear in your original library. This method works well if you have a second computer on which your library only shows tracks in the cloud.
When I went back into my original library, the iCloud status for those tracks were shown as "removed". iTunes Match will now ignore those tracks. You can now add new tracks provided you kept matched and uploaded to less than 25k. I keep a smart playlist any track with iCloud status = matched and any track with iCloud status.
If you have exceeded the limit, the iCloud status will tell you so but even after you have deleted the excess tracks, you might still get this message. You may find that using the above method will fix the problem BUT i can not verify this. If you back up your library regularly to may be able to restore the iTunes library.itl from a time immediately before you first had exceeded limit problem."

Media Encoder Mbits/s Limit Question...

In PP2.0 the Limit with the bitrate on .wmv is only 10Mbits/s.
Yet most 1080i & 1080p avchd cams are around 17-18Mbit/s. I reckon 20Mbits/s should be available in Media encoder.
I haven't used CS4 yet, what is it's limit? If its still 10Mbits/s, would that be good enough for a final render in avchd? Or would it be better to go a diff codec like H.264 Blu ray? I really Like .wmv for PC Playback.
Also what is the best Bitrate Mode to use?
:Constant?
:Variable Constrained?
:Variable Unconstrained?
Thanks...

WMV and other export options are there to compress your video clips so that they can be more conveniently viewed (downloaded) or handled. The object of exporting them tp other formats is to reduce the size of the output files; rherefore you want a lower bit rate out of the export process than your AVCHD files.
You will have to experiment a little to find the lowest bit rate that gives you acceptable quality. It depends on the resolution that you select and several other factors.

Credit Limit Question

Does SAP store Credit limit Deviation or does it calculate on the fly. If so what documents are taken into account when determining if the customer is over the credit limit?
Thank you
Chintan

Hi Chintan,
There is a report called 'Customers Credit Limit Deviation' under Business Partner Reports. If you want to see what is included in the credit/commitment level calculation, go to the Help (F1) file - it explains it in detail.
You can also set so a warning comes up if a user posts a transactions that affects the credit/commitment level - go to Admin / General Settings / BP tab to activate this warning.

Customer Has Exceeded Credit Limit Question

Hi
At the moment when we raise an order for a customer with a credit limit it appears a warning message saying that the customer has exceeded his credit limit.
This information is a bit misleading if the customer has yes exceeded his limit but only because the outstanding invoices are not due yet ie the Due Date may be 31st May 2010.
Is there a way to combine the two information and inform the SAP user when the payments terms for invoices have been exceeded, not just the credit limit?
Thank you.
MB

Hi Matthew ,
Both the thing are different :
1. Credit Limit is only for the Alert or you can block the further transaction .
2. Next you are talking about the Aging report for the outstanding payments .
So both having different aspects , you can not directly combine the both. But if you want then you can use some reporting tools .
Thanks

Invoice Verification Tolerance Limit Question

Hi All,
I am in the process of learning MM basics and have a question. Supposing, I set all the tolerance limits for logistic invoice verification to "Do Not Check". This means that I set both BR ( Percentage OPUn Variance (IR before GR)) and BW ( Percentage OPUn Variance (GR before IR)) to "Do Not Check". Now when I create a purchase order, can I post an Invoice Receipt before Goods Receipt or not.
My reasoning is that since we do not check whether IR/GR comes before GR/IR, the system should allow us to post IR before GR. Is this correct. If not, where is the flaw in my reasoning.
Thanks for your help and time.
Regards
Anu

Hi All,
Appreciate any help from the expert,
Let's say I have created PO in ECC 6.0. I have un-ticked the GR based IV, and over delivery qty or under delivery qty is being st to 10%.
The reason it had been being set up as above since the user might have invoice comes before GR really done.
then the question is :
1. the User wants to control in terms of amount/qty of invoice that should not be exceed the amount or qty PO. what should be configured in invoice blocking setting?
Thank you in advance.
Best Regards,
Daniel

BulkCollect ...ForAll ... Limit question

Exactly. Only you are familiar with the environment your software is going to run in.
On a data warehouse, I'm using a LIMIT of 10000 for a bulk process that sync's with production - as that is the optimal setting ito performance and PGA utilisation.
On another high volume platform, I'm using a LIMIT of 100.
Horse for courses. And do not let anyone else tell you otherwise. There are no fixed magic and golden parameters in performance tuning.
Best that can be given to you is performance guidelines. However, at the end of the day no two production environments are identical in every respect. So what works in one may not work in another - and often not.
A word of advice though. Do not hardcode the LIMIT clause in your code. Consider using package constants instead.
Reason. This allows the DBA or Production Admin/Owner to further fine-tune your code. During initial deployment your process may have been run with others during peak periods and the LIMIT clause reduced to a 100 or even less.
Now the same code is scheduled for off-peak periods where it will have most of the free system memory of that platform for itself. Having a bunch of constants to change allows the LIMIT to be changed.
In other words, when you code for performance, provide performance knobs for the guys in production to turn up and down. Instead of hardcoding performance related parameters in your code.

Total Ink Limit Question??

I recently upgraded to IDCS4 (v6.0) on a Mac. I am having a problem with total ink limits not agreeing between Photoshop and Indesign.
I prepared a CMYK document in PSCS4, embedded a GRACoL#1 profile, and adjusted the image so my total ink limit is 300 in the darkest shadows. Then, I placed that image into IDCS4. My color settings in ID are set to the exact same CMYK profile, and my policies are set to honor the embedded profile, Relative Colorimetric, BPC. When I check the TAC in ID, it shows that I have over 320 in some areas, but that is not the case in the original Photoshop file. Is Indesign converting to the default document profile and forcing the blacks to hit the 320 TAC in the GRACoL profile even though they are the SAME profile? It doesn't seem to matter if I set CMYK to Preserve Profiles, OFF, or whatever in Color Settings.
If it is just assuming the GRACoL profile for readout, then I will just go by what is in Photoshop, which I trust more than I do Indesign. But, I don't want to have some number conversions going on behind the scene, pumping up my ink limits.
Any suggestions?
Thanks, Lou

Well....I thought it made sense, but I am not so sure after more playing around.
I reopened my placed TIFF documents in Photoshop, set my darkest blacks to 300 TAC, and resaved them without any profile. When I relink these files to my Indesign document (files have no embedded profile), I get different ink limits than what shows up in Photoshop.
For example, if I set ID Color settings to "Emulate ID2 CMS OFF", those same blacks read out as 266 TAC in the Separations Preview box, even though they are set to 300 inside Photoshop. That makes no sense to me. Color management in ID is off and the file I placed has no tag! What is that about?
If I turn ON color management in ID, set the default CMYK profile Gracol2006_Coated 1v2, (which has TIL of 320), set CMYK to Preserve Numbers (Ignore Linked Profiles), the same placed file shows 320 TAC in the black areas, even though I have placed an untagged file.
And if I set up a Proof Preview to US Web Coated SWOP v2 (which has a 300 TIL), the readout in ID shows 300 TAC in the blacks.
So, it looks to me like ID is doing calculations of its own to determine TAC. It either uses the document default if no other profile is selected, (even if the file is untagged), or the proof condition if enabled. With color management turned off in ID, who knows what it is doing.
BTW, if I check the "Simulate Black Ink" checkbox when setting up a Proof Preview, the ink limits do drop closer to what is in Photoshop, since no black remapping is taking place, but TAC still does not match.
I am probably missing something here, but if not, this is as useless as tits on a bull, and seems rather screwed up. What am I missing? I'm not new to color management and have been doing this for years, but I am new to CS4.
Thanks, Lou

Itunes u -Student limit question.

I am getting ready to start the school year off using iTunes U. I have just been told that iTunes U limits the amount of students per course to 50 students total. I was wondering if this is true? This will be an issue for me as I have two sections of one class that is over 75 students.
thanks!
Lucas

The number of students per course is a function of affiliation:
https://itunesu.itunes.apple.com/help/index.html#itu16F92805-A89F-4DCA-9BF7-8B6A C9F5636D
Affiliated instructors may have more than 50 students in a private class. (Yes, the help text is ambiguous about this.)

K7N420 HD Controller Limit Question

I need to control more than 4 drives and thought the answer was a controller card. When I cable a HD to the the controller card it wants to use it as the booting drive. Is there a limitation in the MB that prevents more than 4 drives even with a controller card? If not any suggestions to solve the problem?
Semper0

Hi,
I've used a PCI ATA133 IDE card (RAID) in my K7N420 Pro (as well as my onboard IDE connectors)!
The motherboard has no limitation in this regard - that I know of - except maybe IRQ assignments, but this depends on what other hardware you have installed!
However, some pieces of software act strangely when a PCI card is attached (I suppose it depends on the type of card you buy). Those that I know of are "Drive Image 2002" (when run from floppy) and "EasyRecovery".
It may be worth your while buying a PCI card that has a chipset that WinXP (or other versions) can recognise without third party drivers, as you are less likely to have problems.
I should say that I had no troubles with my PCI card except for the two pieces of software I've previously mentioned!
