What are various restrictions in BW like max structures etc

Hi,
         I have few questions.Kindly clarify them.
1. What are the various restrictions we have in BW like
    No of structures in a query - 2(maximum)
    No of Key Figures in Fact table - 233
    No of characteristics in a dimension - 248.
    What are all the other restrictions like how many queries can be in a work book and any other restrictions like that you are aware of.
2.  How can we control the population of Statistical tables like Extraction Queue and update tables.I know that  we can use direct delta ,Queued delta and unserialised V3 update modes.But that will be for populating Delta Queue.How can we control whether it has to use V1,V2,V3 methods.
     Kindly clarify them.Thanks in advance.

Sai,
Delta is set by the extractor you use and the way you want data to come into BW ( Push / Pull )
There are a lot of restrictions in BW but in most cases it is for an extreme case and if you wish to overcome / see the constraint as a serious limitation it would mean that :
1. You design is faulty or some very unique design requirement which is not supported by BW in its current state
2. Some very unique client requirements which you think can be satisfied only by trying to find a workaround for the limitation/restriction.

  • What are various ways

    If its a off-topic please execuse me. But i am curious to know them. As there are so many experts here who have almost worked or have knowledge about different tools or software applications which do different tasks.
    As i am one of mumbaikar(mumbai normal person, India) and eyewitness for yesterdays serial bomb blasts and want to know whether internet can also be misused for communication.
    What are various ways to misuse internet for secret communication by terrorists or anyone who always think to do harm to human community.(by all means in terms of using software for all their communication)

    One could use forums to find out how to abuse the
    internet and then put what one learned into play.
    Why all these steganography-as-terrorism questions
    the last couple days? Homework assignment, or new
    approach for al qaeda?Sir jverd,
    I respect you as you being seniors here. But as i
    told you i am one of the co-passenger in the bomb
    blast but i have luckily escaped. I am just a newbie.
    I will feel to do something good for my nation. But
    just lack of experience and lack of information i am
    just curious of any concepts or links or information
    that will lead me to atleast 1% to do something good
    for my nation. But rather if i can say atleast i can
    save atleast one life if i can gather good
    information and go on to try myself and findout
    various ways to atlest have good knowledge and spread
    awareness. I dont feel this is something wrong.

    I have no idea who you are. You might be a survivor, or you might be one of people responsible for the bombing. I have no way of knowing, and am not making any judgements on you.

  • I'd to lengthen my USB cable with Cat5e or Cat6.  What are the restrictions?

    I'd to lengthen my USB cable with Cat5e or Cat6.  What are the restrictions?  My iPad will live in my office upstairs and my computer is in a rack down stairs (about 50 feet away).  Will the iPad and computer connect at this distance?  If I use a powered balun will it help?

    USB has a maximum limit of about 5 meters. To go longer than that, you will need multiple intervening self-powered hubs, though that can be problematical. Using the simple Cat-5/6 "baluns" may not work because they can cause signal timing problems. There are some USB extender products that can successfully use Cat-5 cabling over significant distances, but they're not cheap.

  • What are various data speeds supposed to be?

    I am doing my research now on the iPhone while awaiting the end of my Sprint contract. I currently on the slow Sprint data network using a Treo 650. All my bookmarks are to text based mobile sites: BBC, NYT, etc.
    I was playing with an iPhone here in Phoenix yesterday & the full graphic sites like BBC World News displayed pretty slow on the Edge network.
    What are the various "published" speeds supposed to be for the slower Sprint, ATT Edge & ATT 3G Networks? In "theory" how much faster is 3G over Edge?
    Thanks.

    In theory EDGE has a maximum speed of 220 kbps, and 3G 1500 kbps as implemented by AT&T. In practice I get about 200 kbps and 1000 kbps respectively using the aircard on my laptop. So 3G would appear to be 5 times faster than EDGE. Some magazines have done real comparisons between the iPhone and a 3G PPC. The found much smaller differences, from sites that took about the same on both to a best case of the PPC being twice as fast as the iPhone. The reason is that a website requires many requests to the server, and each one requires the overhead of setting up and tearing down a connection. So this "latency" slows down the useful throughput. This would not be an issue for email or youtube, however.
    On my laptop 3G is faster than EDGE for web browsing one page at a time, but not strikingly so. The difference is that I can launch a browser with multiple tabs loading simultaneously, and for that scenario (and for downloads) 3G is much faster.

    since in this case you dont seem to have a key value to figure out what your header is, it is better to go for a two level mapping. i.e first read all the data - each line as an xml tag. and in the first mapping group it as required and then use it for your original mapping.

  • SWF_WORKPLACE - can we use it? And what are the restrictions?

    Hello,
    I'm in the middle of specifying a new ESS/MSS role out and one of the points that has come up is the need to use the UWL, and specifically substituting approvals/task during absences. There is a desire that we should be able to allow/disallow certain users for being used for substitution. (This is something that I do not believe exists as standard functionality)
    With the portal based UWL being in Java we are reluctant to enhance it, however, I can see that a WDA app SWF_WORKPLACE exists which seems to do the same thing. And WDA is much easier to enhance (and support that enhancement after a support pack update).
    It seems that this functionality is only released for NWBC [Note 1149144 - SWF_WORKPLACE:Composite SAP Note Business Workflow Workplace|https://service.sap.com/sap/support/notes/1149144]
    >You can call the Business Workflow Workplace in SAP NetWeaver Business Client (with PFCG connection). The integration in the Enterprise Portal is currently not supported.
    >In addition, you cannot use the Business Workflow Workplace directly in the backend system since certain functions * require SAP NetWeaver Business Client.
    - my emphasis
    Does anyone know what these certain functions are? (possibly OBN?) And what bit of portal integration is not supported?
    As far as I can see, although it only allows tasks to be launched using object based navigation and reads table swfvgt with a key of NWBC cl_swf_powl_launch_services=>c_wlc_nwbc , it still uses the standard portal integration interface to launch the OBN. I can't see what functions wouldn't be supported in the portal.
    Thomas Jung mentioned this app in this thread Transaction SBWP - although I think he confused what looks like a WDA view of the absence approval application for the substitution logic - which is built into the SWF_WORKPLACE application.
    Other than that - no-one seems to have discussed/used this app anywhere - could you tell me why?
    Thanks!
    Chris

    Thanks Harshit,
    the BAdI, although allows us some control, doesn't really meet the requirement (although it might just have to do), for example I'd like to be able to allow different users for different profiles - so leave (profile1)  has one logic and financial approvals (profile2) another - although this can be done, it seems to be after the user has made the choice rather than restricting the search results in the first place.
    I had a search for new notes regarding SWF_WORKPLACE and couldn't find any, so I doubt it is even enhanced in 7.02. As it stands the lack of functionality that it presents - plus the SAP disclaimer about using it with anything other than NWBC makes me think were probably just going to have to go with the Java based app and the BAdI.
    Thanks for your help - and good to see you on SCN!
    Cheers,
    Chris

  • What are the restrictions &pitfalls of renaming a table vs select * into...

    Hello all,
    I've got a situation coming up possibly, that I'm looking at where I may need to rename a table that has about 3 TB of data in it.
    I'd looked at doing the oracle RENAME command, and it mentions that some restrictions that would error out would be:
    views, synonyms, and stored procedures and functions that reference the table.
    I'd been looking around on different sites researching more, and found some saying that tables with foreign keys, check constraints would also error out on this....but in the Oracle docs I see it saying:
    "Oracle Database automatically transfers integrity constraints, indexes, and grants on the old object to the new object."
    Were the other non-Oracle site references maybe to older versions? I'm using 11Gr2.
    The other part of this is that the app designers really want to recreate the original table. Essentially this is doing
    TABLENAME1 -> TABLENAME1_OLD
    Then recreating TABLENAME1 anew empty for new use.
    My original thoughts were to do select * from TABLENAME1 into TABLENAME1_OLD, and then truncate TABLENAME1....but with the size of the data (and this will eventually be done in PROD), I"m trying to say that doing the RENAME and recreating the empty table would be less resource intensive.
    Would the rename and recreate table be the way to go?
    If so, then I need to make sure I know all the restrictions and pitfalls on rename would have....
    Thanks in advance!!

    {quote}
    You are missing a key piece of the requirements
    What is the intended use of the OLD and the NEW tables?
    Why do you need a new table with exactly the same name unless you intend to use it exactly the same way you were using the old table? And if that is the case it seems to me that other tables with foreign keys need to be truncated also and point to the new table and not the old one.Unfortunately, I don't know. This is just a request the devs have, and I'm not sure of their reasoning, but this is what they're asking for, so, I'm trying to research the best way to do what they request.

  • What are the restrictions of the bulkloader?

    We want to use BulkLoader for Personalization server 3.5.
    How many files can BulkLoader index? We have files for
    different 17 portals. Shall I put all files in one directory
    and make the difference by using meta-tags or put files per
    portal in different directories.
    Can somebody tell me the restrictions of bulkloader?
    Thanx,
    Levent

    Alex,
    Both examples you mention are possible with JHeadstart by customizing the Generator Templates. Add a control item in the formGroupButtons or tableGroupButtons template for example, or customize the groupContent template for a specific group and replace it with references to your own bindings, which you then prevent from being overwritten by unchecking "Clear Page Definition before generating".
    Hope this helps,

  • What are the restrictions/limitation in lookout with the use of graphs created in third party software? When we use these kind of graphs we normally loose resolution, shadows or 3D effects.

    We don't know exactly how does lookout handle .bmp or .wmf files created in third party programs like CorelDraw, since we have a different response from lookout to those graphs. We loose the shadows effects, we don't have a transparect effect, etc.
    Thanks in advance, any help is welcome.

    It shows Peter's doing its jobs properly.
    Anyway there is no more communication from Sony since awihle. If you can have any news.

  • How ro restrict BEx Items like Report Designer,etc..

    Hello Friends,
    I have a situation where my end users should not be able to run Report Designer,Web Analyzer,Planning Modeller and BEx Broadcaster.
    Can any one suggest me how to do this.
    Do we have any auth objects that control them.
    I tried to look many ways i didnt find any way.
    Thanks,
    Ram

    for working on broadcaster user should have S_RS_ADMWB with field RSADMWBOBJ = BR_SETTING, and object S_RS_BCS.
    and for saving and executing the formatted report in report designer user should have access to S_RS_ERPT.
    make sure your endusers do not have these. that would do your job. users can get in to broadcaster and report designer, but they can't do anything. getting into these tools cannot be prevented until what I know.
    S_RS_TOOLS was made a mandatory check in NW04s. so unless a user has it he won't be able to get into Web application designer.besides that S_RS_BITM and BTMP would help to restrict at owner level.
    S_RS_TOOLS takes the 'COMMAND' = WEBPUBLISH.
    unless you add this object to a user, he won't be able to get into WAD.
    SAP din't provided anything like this to other tools until now. may be not many customers are requesting for it.

  • What are the different licences?

    I'm thinking about getting the Production Premium suite, but I'm slightly confused about the different licences... As far as I can tell, there's a student licence, and a "normal" one... Is that all of them?  Also, what are the restrictions for each?
    At the moment, I just want to build up my portfolio.. I don't have any plans to publish anything commercially - however, I don't want to be restricted from that option, should I wish to do so in future.  Which is the best license for me?
    p.s. sorry if this is the wrong forum to post this in!

    From what I've learned of the iPhone 5 I got 3 days ago, I can identify the following:
    Off, phone completely de-energized. Press the power switch for 3 sec, flick the slide onscreen.
    Sleep, phone is on but screen dar. Briefly press the power switch.
    Normal, phone on the home screens
    Airplane mode, fully on but with all radios off.
    Do not disturb, cellphone dark but only receives calls from selected sources.
    I'm sure there's more to discover.

    I listen to audio books in my car while driving to and from work and also while driving to Northern Michigan on the week ends. The TransPod is the only accessory I have tried that actually allows me to listen to the iPod through my FM radio without any interference or static. This is a great solution until the car companies figure out that millions of drivers want to listen to their iPods while driving.
