"density" in SAP_INFOCUBE_DESIGNS

Can someone tell me what is the meaning of "density" that is displayed in white text for each cube from program SAP_INFOCUBE_DESIGNS ?

Never really noticed the Density measure - with my color pallet, that line of text is barely visible.
I think Patrick is talking about the size of a dimension relative the the size of the fact table. Don't believe that is what the InfoCube density is trying measure.
Here's my interpretation ( could be full of you know what, but got to take a stab at it ) -
As Bhanu points out, it's the number of fact table rows divided by the product of the multiplication of all of the row counts all of the dimension tables. ( hope that creates a clear mental image... yikes!)
This product of the multiplication of the dimensions provides the number of cells in the OLAP cube, assuming that every dimension is being considered. Now in reality, it would be really rare that every possible combination dimension values exists in your data. If it did, you would have a density of 100% - that is every cell in the OLAP cube would be populated with data.
The density measure then, is trying to tell you what percentage of the cells of your OLAP cube are populated - or put another way - of all of the theoretically possible combinations of dimension values, how many actually exist.
What do you do with that info? Could perhaps be used to indicate that there are certain relationships among your characteristics that you might want to explore (which is something you would typically look at when defining dimensions during the modelling phase. Have to think a little more about it's use.
That's my best guess for what it's worth. Hey, if I'm wrong, I at least hope it sounded good!

Thinking some more (always a dangerous thing) Not sure of SAP's cube design with respect to the amount of storage a cell in the OLAP cube consumes if it has values vs cells without values. Maybe there is no difference, but if there is, the density measure might give you an idea of how memory the cube would consume, e.g. a cube with 10,000 cells with 9,000 populated with a value might consume more memory than if the cube only had 1,000 cells populated. But, I really don't know - maybe a null cell consumes just as much storage - sounds like a question for the Cube gurus at SAP.

Data Load into 0FIAP_C03 - InfoCube consuming very long time

Hi,
I'm loading data into the InfoCube - 0FIAP_C03 from the DSO - 0FIAP_O03. On a daily basis I delete the contents of this InfoCube and reload full data.
In the DTP monitor I can see that the step 'Overlapping check with archived data areas for InfoProvider 0FIAP_C03' under 'Updating to InfoCube 0FIAP_C03 : 50000 -> 50000 Data Records' for each Data Package is taking the most amount of time. It is generally true that the step 'Overlapping check with archived data areas for InfoProvider <Cube_Name>' takes the most time. But is there any specific reason for this? Also, is there any thing that can be done to reduce the time taken to execute this step?
Thanks,
Sri.

Hi Sri,
Ideally it should not take much time-
I think the reasons would be:
1) Volume of data in Source DSO
2) Complex logic in Srart/Field/End routine
3) Cube Index (Delete cube index before load)
Also check the dimension design of your infocube --> SE38 --> SAP_INFOCUBE_DESIGNS

Fact table is GT Dimension table

Hi All
Where can i find the relation between Fact table and dimension table sizes. If i want to check whether my dimension table is greater than fact table then how?
If i can use program " sap_infocube_designs" then when i am trying to execute it it is not working.
regards
Naga

I dont think SAP_INFOCUBE_DESIGNS doesnt give u the size of the fact table rather the density and the row count in the cube.

Laserjet CP1025nw color, unable to change Print density

Hi,
I need to raise the "Print Density" to 5 (for pcb toner transfer) on my Laserjet
CP1025nw color, but when I open the printer properties I do not have that option
in the device settings tab, despite what is said on the help page of that model.
OS: Windows XP
The printer is on the USB port.
The pilot is: HP LaserJet Professional CP1020 Series + last update
How can I change that setting ?
Please help !!!
Thank you in advance for any help you can bring !
All the best,
This question was solved.
View Solution.

From what you describe you want to increase your toner density on your subsequent print jobs. First of all, if you have not, you should uninstall this printer and make sure that the drivers are the most up to date using the website I will link below :
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=us&lc=en&dlc=en&product=4052972
Here you should also check for your firmware to be sure that it is up to date.
I would also, both before and after, check under "Printer Preferences" (not properties) and see if there is a way to change the density under the Paper/Quality tab.
Let me know if this helps you out!

Determining spectral density of poisson process (carson theorem)

Has anyone ever determined code for working out the spectral density (or
equivalent) of a Poisson process, based on Carson theorem (or a variant
thereof)? It doesn't have to be in Labview, but that would be the easiest (or VB).Message Edited by Jo on 05-01-2005 11:34 PM

Memory density clarification!!!

I started another thread on this, but the update to that thread is big enough to have its own thread. However, for the history the link to that thread is https://forum-en.msi.com/index.php?topic=127102. In a nutshell in that thread I wanted to know if I could mix memory modules of different densities on my X58 Platinum SLI. I had previously mixed densities on my Asus P4 build, so why not with my MSI I7 build? Unlike Microsoft I knew Intel would not go backwards with capability. However, the moderators on this site, my X58 Platinum SLI user’s manual, self described gurus on this site, and even MSI tech support with 2 different support tickets all told me I could not mix memory modules of different densities! But I carried on thinking that they were all wrong. As you can see by the supporting picture evidence they are all WRONG and my thinking is right. You CAN mix memory modules of different densities. Not only can you mix them, but it works well enough to overclock. I currently have 2GB memory modules in slots A0-C0 and 1GB memory modules in slots A1-C1. As you can see the BIOS as well as Vista both report the correct 9GB. If you do the math there is only one way to get 9GB and that’s to mix memory module densities.
Moderators: don’t be so quick to tote the MSI line if you have not seen it with your own eyes!
End users: if you suspect something is wrong in your manual it probably is. Most mobo manufacturers copy instructions from one mobo model to another and frequently put out false information. As we can see MSI is no exception since they published the following lines:
- DDR3 memory modules are not interchangeable with DDR2 and the DDR3
standard is not backwards compatible. You should always install DDR3
memory modules in the DDR3 DIMM slots.
- In Three/ Dual-Channel mode, make sure that you install memory modules of
the same type and density in different channel DIMM slots.
Anyway . . … I wanted you all to know that you don’t have to throw away memory modules if they are not the same density. If everything about the memory modules are the same except for the density the SPD capabilities of your mobo will sort the rest out!
There were some pictures here, but sorry I had to stop hosting them at 3:42p, 21 May. Just a bandwidth limitation, that's all. Yeah, I know about photobuket and the like.

I am not really sure if you are seeing the full picture here. The fact that you had no problems when mixing different memory modules on two different platforms does not prove anything. Statistically, it is not significant enough to come up with a general statement like "the manual is wrong" or "yes, you can mix, no problem". That is simply not
very responsible as part of general advice.
Nobody here will tell you that unidentical memory modules will ultimately cause problems on every system. It can work just fine (just like in your cases), however, most of us have had to do with many systems in the last couple of years and we have come across users with many different system configurations here and in other forums. There are numerous cases in which mixing memory unidentical memory modules led to unstable or unbootable systems. There are also numerous cases that were issue free. Even if the success rate is/was (let us say) 66%, are you really serious in trying to tell us to ignore a 33% failure rate just because you did not run into any problems on two systems?
I have mixed my Kingston HyperX KHX8500D2K2/2G sticks with a kit of G.Skill-Kit F2-6400PHU2-2GBHZ memory modules on some of the systems I had here in the last couple of month. And yes, there were cases in which that worked just fine. However, it caused horrible stability problems on some of the configurations I tested and these issues could be simply resolved by using identical modules. A friend of mine recently bought a second pair of OCZ DDR2-800 modules (same model he already had) and ran into sincere bluescreens and system crashes. He talked to OCZ and after they made him compare the production dates of the modules, it came out that the newer kit used different memory chips. OCZ exchanged the old kit for another kit of the same revision as the newer one. Why: Because they are very well aware of the fact that stability problems are not unusual in such cases.
I am honestly wondering what you are actually trying to prove with this thread. If your system is stable with your memory mix, that is wonderful for you. No doubt about that. But, again, just because you had success regarding your specific configuration, this does not mean that this will be true for all system configurations. This kind of Inductive reasoning is rather misleading.
You are claiming the manual is wrong. Well, it isn't. If MSI removes the remark "In Three/Dual-Channel mode, make sure that you install memory modules of the same type and density in different channel DIMM slots." from the manual, what are you going to tell users that actually have problems that disappear once identical memory modules are installed? They will say: Why isn't there a note in the manual that advises system builders to use identical modules?
Dual and Triple Channel operation is all about synchronous read & write access to the system memory to enhance system performance. How synchronic can read/write access be on systems with an asynchronic memory configuration?
One more thing: I have read through your other thread again and as far as I see it, you are not referring to the density of the memory modules, but to the capacity/size of the modules (1 GigaByte vs. 2 GigaByte). Memory Density and Memory Capacity/Size are not the same things:
The term "memory density" refers to the kind and organization of the memory chips that are used on a memory module. Corsair's Datasheets do not specify the memory density. But let's have a look at a Kingston Datasheet for Comparison:
http://www.valueram.com/datasheets/KVR1333D3N9K3_3G.pdf [3 x 1 Gigabyte]
This quote from the datasheet refers to the Memory Density:
Quote
eight 128M x 8-bit
"128M x 8-bit" means a memory density of 1024 M-bit (or 1 GBit (note: not MByte/GByte)).
Now look at this kit:
http://www.valueram.com/datasheets/KVR1333D3N9K3_6G.pdf [3 x 2 Gigabyte]
The memory capacity/size of the module has doubled, yet the density is the same:
Quote
sixteen 128M x 8-bit
Again: 128M x 8-bit is 1024M-bit (or 1G-bit).
The memory size/capacity depends on the number of 128M x 8-bit Chips that are used on the module: 16 x 1024 Mbit = 16384 Mbit. If you devide that number by 8 (bit -> byte) you get your 2GByte. Although the memory capacity differs (1GB vs 2GB), the memory density is identical (1 Gbit in both cases).
One more example for comparison:
Instead of 128M x 8-bit, the density can also be 64M x 8bit for a give 1024MByte Module.
Example:
http://www.valueram.com/datasheets/KVR1066D3N7_1G.pdf [1 GByte]:
Quote
based on sixteen 64M x 8-bit DDR3-1066 FBGA components.
Density is: 64M x 8-bit = 512 MBit x 16
If 512MBit modules are combined with 1024MBit modules (different density), the chance that the system will not boot at all or be horribly unstable is very high.
Quote
Yes, the manual is wrong.
No, it is not. It states the adequate compatibility conditions for synchronous/interleaved multi-channel operation.
Quote
there are no specific DDR3 slots.
There are six slots on your board that are specifically for DDR3.
Quote
DDR3 memory modules are not interchangeable with DDR2 and the DDR3
standard is not backwards compatible. You should always install DDR3
memory modules in the DDR3 DIMM slots.
This is actually a very important piece of advice. For experienced users it may fall into the same category as "Attention! Hot Beverage" on coffee-to-go cups and the "don't use the microwave oven to dry (living) pets" in some microwave user manuals. In the last two years I have met at least five users that wondered why the board won't boot after forcing DDR memory modules into DDR2 slots or DDR2 memory sticks into DDR3 slots.

SMMCIM12     Material
SMMCIM13     Batch
SMMCIM14     Stock type
SMMCIM15     Vendor
SMMCIM16     Sold To
My questions are as follows:
1) It seems that if the dimension table is marked as Line Item it is not shown in this report. Is there a report otherwise that I can run which can tell me whether I have correctly set Line Item dimension for these dimensions, if not what are the consequences if I have set this wrong
2) In the example above the dimension below should be set to Line Item
SMMCIM1            /BIC/DSMMCIM12      rows:         57    ratio:         47 %
3) How can I determine for the line items whether it should also have a high cardinality setting
Thanks

Hi Niten,
I would rather advice you to relook at the design than go in for "line-item" dimension. You can go in for line-item dimesnion only if you feel the design is correct. The disadvantage of a line-tem dim is that you can have only 1 char in the dimension. High cardinality would use the B-Tree indexes instead of the normal Bitmap indexes. High cardinality is advisable to use if you are using line item dim.

Whats the difference between high-density and low-density ram?

I bought what I thought was supposed to be a cheap 256 mb chip (pc100 or 133) but the g4 400 read only 128mb, The fellow in the store that sold it flipped out when I told him I had a Mac and said something about high density and low-density.Another guy in the store described it as being one sided and two sided.
I don't know what my machine needs. I got my money back but he would'nt let me exchange the chip for another, me thinking it was simply mislabeled.

The QuickSilvers use PC-133 SDRAM and are compatible with high-density memory chips (256 Megabit), so that 16-chip 512 MB and 8-chip 256 MB non-ECC DIMMs are supported. A low density, 16-chip (128 Megabit) 256 MB DIMM is also supported.

HP 1300 Laserjet & HP 2605dn Laser Jet printers print density problem

I have both an HP 1300 b/w and HP 2605dn color laser printer. In the last week both printers have changed the output density. The 1300 print is coming out lighter than it used to, and the 2605 is not print the color tones as it used to. What used to be orange is now only yellow.Other colors are not right either. I can compare them to output a few weeks earlier, and they are much lighter and different color tones.
Both printers have plenty of toner in all cartridges. The toner cartridge on the 1300 was changed 2 weeks ago. The toner on the 2605 is 3/4 full.
This was like something got into the printer drivers and reset some parameters on both printers at once.
Can anyone help me here to check this out and how to correct the problem?

I have the same problem with my laser printer 2605dn. the color is pale, i replaced the cartridges with original hp's but it did not help. I also lost the capability of double side printing that I had when I originally loaded the printer drivers. I noticed this all after I checked the internet for software updates for my printer. Are there any solutions for these problems?
please let me know.

Adjust density on HP Laserjet P2015dn printer

Hello,
I use HP Laserjet P2015dn printer with Windows 7 Ultimate. I would like to ask you how to adjust the density of printing. I couldn't find any similar option in the printer's properties.
Thanks.

Stasko,
I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial printer. You can do this at http://h30499.www3.hp.com/hpeb/ .
I hope this helps.

You are correct, between the higher numbers of users with multiple devices the bandwidth requirements keep increasing.
The limitation of three non-overlapping channels in the 2.4 GHz space is driving more customers to 5 GHz, it is important to have both bands when high density deployments are needed. While many older devices only support 2.4 GHz, we are now seeing far more devices with 5 GHz as well.
The recomendation of 20-25 clients and 8 voice calls on a given 2.4 GHz channel is still a good "rule of thumb" with actual customer data requirements driving those numbers higher or lower. You are right when you say "throwing Access Points" at the problem can degrade the wireless quality as co-channel interference and overall noise floor can rise with multiple Access Points that can all hear each other.
A better approach to the problem is to throw more spectrum at this issue (using 5 GHz channels) and elements of 802.11n (20 MHz) bandwidth on 2.4 GHz.
What we have been doing in high density deployments is to try to minimize the propagation of a cell and focus it in a given direction. This can be done by
1. Managing the RF power of the radios (Access Points) and in some cases the client's power (using elements of CCX).
2. Using the right antennas to shape both Tx and Rx cell size to help isolate, we have recently introduced a new high gain antenna for stadiums that does this well.
3. Limit supported rates, obviously the higher the data rate the less sensitive the receiver is and the smaller the cell size becomes.
4. Enable 5 GHz (that adds far more channels for data throughput)
5. Limit the number of SSIDs in use as each requires a separate beacon (adding to RF utilization)
6. Co-locating access points with non-overlapping channels
There are some challenges, for example; many dual -band clients prefer to connect to 2.4 GHz, and 2.4 GHz is more likely to be busier and subject to interference, so we also enable Cisco "Band-Select" which basically "nudges" those clients off 2.4 GHz and pushes them to 5 GHz so as to free up the 2.4 GHz band when we can determine the client has 5 GHz capability.
So how is this done? well, we do this by listening to the clients and if we detect that the client is sending out probe requests on both bands we know the client can use 5 GHz so we essentially make the 5 GHz band "appear more attractive" to that client.
Note: Client load balancing and Band select are features in the Cisco Unified controller menu.
Also enabling client link (intelligent beam forming) helps direct the signal directly at the client and reduces same channel interference.

External displays with similar pixel density to 17" MBP display?

I've got a 17" MacBook Pro, native resolution 1920x1200, which is quite high in terms of pixel density. I have a 24" external Samsung display, also 1920x1200, which means the pixel density is lower. It works fine, but (as you might expect), screen items increase in size rather noticeably when I drag from the laptop display to the external display. (The 24" LCD Apple Cinema Display is also 1920x1200, so the same thing would happen). I've been looking all over the place, and I can't seem to find an external display in the 20-24" range that has a resolution higher than 1920x1200. Ideally I'd like to find a display with the same amazing pixel density, so everything is the same size on both my laptop display and on the external display. I don't know what that would be--probably something like 2048x1152 on a 20" or 22", and 2560x1600 for a 24". Even Apple's 30" Cinema Display at 2560x1600 (or what I imagine will be the new 27" LCD coming out later this summer, probably at 2560x1600) would suffer from this problem, because while the resolution is great, the screen size is so large that the pixel density is lower and once again screen items would increase in size when moved from the laptop monitor to the external monitor. I don't really care about screen size or cost. I'd buy a 20" display, or a 30" display, at pretty much any price, if the pixel density were identical to my MacBook Pro. Anybody know where I can find something like this?

The pixel densities of the 15" hi-res MBP at 1680 x 1050 and the 17" at 1920 x 1200 are really quite extreme — the 17" slightly more so than the 15". To read the "fine print" on those screens without a resolution-independent user interface (which the Mac OS doesn't yet offer), most users have to sit closer to those displays than they'd want to be to a 27" or 30" display, simply because for a viewer sitting that close to it, the bigger display would extend outward beyond the central field of sharply focused vision. One would constantly be leaning forward and back: in to read the menus or palettes and then out to see the whole screen. That would be pretty tiring. Thus I think it's quite unlikely that we'll ever see 30", 27" or maybe even 24" displays from Apple or anyone else at the same pixel density as the highest-resolution MBPs: 133.2 pixels per inch for the 17" and 128.6 for the 15", compared with 108.8 for the 27" iMac and 97.7 for the 30" Cinema Display). The current standard-resolution 15" MBP at 110.3 actually has a lower pixel density than the 13", at 113.5.
Interestingly, the current 24" Apple LED-backlit display at 113.2 has almost exactly the same pixel density as the 13" MacBook Pro screen. For someone who wanted things to stay the same size when moving from screen to screen, that would be an ideal pairing. But the 13" MBP sure wouldn't be any match for the 17" in terms of screen real estate when each was being used as a stand-alone portable.

Photoshop Save As PDF Settings Text loses 100% Black or Color Density is too High

I am taking a CMYK Photoshop file and saving it as a PDF for a magazine.
By request, the company has asked that the color density does not exceed 260%. In the output setings of the Save Adobe PDF dialog box, under color, I have:
Color Conversion: Convert to Destination
Destination: U.S. Web Uncoated v2 (told to me by the magazine to use)
Profile Inclusion Policy: Include Destination Profile
When I create the PDF, SUCCESS!!! it works where the color density is under 260%.
I verified in Acrobat Pro X by going to View / Tools / Print Production / Output Preview with the following settings:
Simulation Profile: U.S. Web Uncoated v2
Sample Size: 3x3
Total Area Coverage checked and set to 260%
HOWEVER, when I do this, the text goes from CMYK 0 0 0 100 to using all four colors. I have been recommended by the company to keep pure back on the text due to possible registration errors.
If I export out to PDF using the "PDF/X-1a" (inside photoshop pdf export), then I can get the text to keep 0 0 0 100 but the color density goes way over 260%.
Has anyone had this problem? I cannot get the color density to stay under 260% AND keep the text to 100% black.
Any help is always greatly appreciated.

Thank you Mylenium for your reply. What you have said makes sense but I am not sure how to implement it. I did a google search on Photoshop Multichannel mode and I did really find anything helpful or relevant.
I tried playing with the multichannel just the same. I made a copy of my photoshop document first (just in case I screwed up my file) and I converted it to multichannel mode from the current CMYK. (Image / Mode / Multichannel) Under "Channels" I looked at each layer (Cyan, Magenta, Yellow, and Black) individually and the text and other black areas in question were only on the black channel as it should be. Now that I am in multichannel mode, I cannot "Save As" a Photoshop PDF file so I had to do a Print to PDF option. I used the same export setting (or as close that I could tell) that I was using before and I still ended up with the same problem. My color density is under 260% but my black text is using 4 channels.
I also noticed that when I converted to Multichannel mode, the color of the image did change / shift a bit which also has me a bit worried.
Can you describe how I am to implement Multichannel mode to get my desired output? Also, can you elaborate on "custom channel for text blacks"?
I appreciate the help, thank you!

Setting Total Area Coverage (TAC or Density) in InDesign

Is there a way to set the Total Area Coverage (TAC or Density) in the Export options from InDesign?
I feel that the color management tools relate to elements created within InDesign and not placed images.
My printer requires a PDF/X-1a:2001 compliant PDF with a TAC of 240% maximum.
Is this possible using from within InDesign, or do I have to address 'Placed' images within Photoshop or Illustrator?
Thank you for your response, in advance.

InDesign's colour management can be set to affect placed content as well as native content.
Do you have (or can your printer provide, or suggest) a CMYK profile that has 240% TAC?
