General place for newbie datamodeler questions?

With the production release of SQL Developer Data Modeler I'd assume that this forum will draw a bunch of new users. Is there a better place to ask some pretty simple, newbie like questions that won't bother the more seasoned members?
For instance, I am working in a Rails environment, which has some stringent naming conventions, one of which is that all of the primary key columns are numeric and called "id", with the foreign key linked columns called <table_name>_id.  When engineering a logical model to a relational model, the added foreign key columns are all "id#".  Is there a way I can define a naming rule to keep me from having to redo the relation column names?
Also, we have a standard set of columns (mostly Rails related) which appear in every table. Can I define a generation rule which automatically includes these tables?
Thanks

Thank you. I will try changing that setting.
IS there a setting which tells the relational model to automatically create pk and fk indexes? I haven't seen one, and manually setting them up is a tedious task. --sw

    The OTA update capability was not introduced until iOS 5. You will need to connect the device to the computer and iTunes and update it as you did in the past.Once you have updated, you will have the ability to do OTA updates in the future.

    That's because you never registered a rescue email address. The only way to resolve this now is to contact iTunes Support. They are the only ones that can help.

    An absolute URL will be a complete URL, it traces from the abosulte root of a file's location on a server...
    http://www.thesite.com/assets/images/Front_Page_Rotating_Banner/banners.xml
    A relative URL is anything short of including the http://domain..., and is read relative to wherever the file using it exists
    assets/images/Front_Page_Rotating_Banner/banners.xml
    In Flash files though, relative links need to be specified relative to the HTML page that embeds the swf.  So if the swf is in a different folder than the html page that embeds it, the swf's targeting must be adjusted as if it were actually in the html file's folder.

  • Question about decimal places for currencies

    hi ,experts ,
       here is the problem , when i use mb5s, i found the net price has been enlarged 1000 times . I  also found the data of the table EKPO has been enlarged 1000 times. So ,i check the decimal places for currencies , i found there are five decimal places , the standard system is two decimal places . 
       Does this mean that we cann't  change the decimal places in SAP?  If we can change , what should we do for configuration ?

  • Newbie wireless question (slightly off-topic)

    I didn't want to post this here as it's not entirely an Airport-specific question. I posted this to the iBook forums, but nobody there has answered so my apologies if this is not welcome here. (Any moderators can remove it if that's the case.)
    I've been using computers extensively for over a decade, but I'm a total newbie to wifi. I just set up a wireless network in my house and would appreciate some advice/feedback.
    My main concerns are whether or not my network is reasonably secure. I know there is no such thing as perfect security, but I don't know if what I've done is good enough or not.
    I don't have an Airport base station, but I do have a D-Link Airplus G and an Airport card in my iBook. I have WEP set up on the router and I have enabled MAC filtering, listing only my desktop and my iBook, excluding all others from the network.
    I'm fairly certain that nobody in my neighborhood is going to get into my machines this way or be able to sniff my network data stream, but am I right in assuming that nobody can "piggyback" on my Internet connection too? Presumably, if everyone but my own machines are MAC-filtered and kept out, then the Internet connection is also protected. Is that how it works?

    WEP and MAC filtering are better than nothing, but you can do better. These are my suggestions:
    1. Use WPA with a pre-shared key (PSK) and TKIP encryption on your Netgear router, along with an alphanumeric passphrase of at least eight characters not found in any dictionary. The equivalent setting on your Mac is "WPA Personal". Unlike WEP security (which an expert can crack in under half an hour), WPA security is currently unhackable by any practical means as long as you use a non-dictionary passphrase. One last point - WPA security requires all your wireless Macs to be running MacOS 10.3 or newer.
    2. MAC filtering is (these days) essentially useless as a wireless security method. Using "packet sniffing" of traffic on your wireless network to find out what MAC addresses are used by computers on your network, and a PC that allows its MAC address to be cloned so that it is identical to the MAC address of one your own wireless computers (which is possible with most PC wireless network adapters) even an amateur hacker can defeat MAC address filtering in minutes.
    By the way - I don't think your posted message here is off topic. In my opinion, the Airport discussion forums are the best place to post any questions related to usage of wireless networks. Questions of this nature are virtually never specific to any Mac model.

  • Newbie script question... consecutive numbers with update.

    complete newbie type question... this is also my first post.  ( I am using CS3)
    does anyone have a script which can make it so I can add numbers into the text consecutively.
    for example, if this is my text "the big fat dog sat on the very wide mat, but was then displaced by a unfriendly cat."
    and I wanted to place a number 1, number 2, 3, etc at points in the text so it read, "the big fat dog1 sat on the very wide mat2, but was then displaced by a unfriendly cat3." but later wanted to add another number and have later numbers update themselves, so the text then said, "the big fat dog1 sat on the very wide mat2, but was then displaced3 by a unfriendly cat.4".
    by inserting the three, the previous three became four.
    Has anyone got something which might be useful in this regard.
    Many thanks
    Steve

    i wanted to avoid footnotes as they leave a bar at the bottom of each page.
    i wanted a script to do something similar to footnotes but not much further.
    does anyone have just a simple script that can do what I asked?

  • Decimal places for JPY currency in change documents

    Hi Gurus,
    For opportunities in SAP GUI the change documents for JPY show incorrect numbers.
    The number is divided by 100 (two decimal places added).
    Checked the CDPOS table and found the values already divided (two decimal places added).
    SPRO->General Settings->Currencies->Set decimal places for currencies is set for 0 decimals for JPY.
    Is there any way I can get correct values in the change documents?
    Please advice. Any hint is useful.
    Thx,
    Martin Kuma

    Hi Naren,
    Thank you for the tip, however the TCURX table is changed via customizing and should be changed only during the system initialization.
    What I would like to do, is to assure that the system displays the values in change documents correctly. It should apply the currency conversion for the data displayed the same way it does for all the tables.
    Do you have any idea, how should I do this?
    Regards,

  • Business Place for document  could not be determined

    "Business Place for document  could not be determined".
    Could any body please help me to solve this problem.
    I maintained the following settings in system
    1. T-Code: J_1IEWTNUMGR
    UN04     SC04     194C     02
    2. T-Code: J_1IEWTNUM

    3. T-Code: J_1IEWTNO
    Maintained Number ranges
    I posted vendor document and I gave Business place and Section code also. Even After all the settings I am getting this problem. Please let me know is there any steps I missed are any thing I have to maintain in system.
    Best Regards
    Raj

    Hi Pavan,
    Thanks for you replay. I checked in table, data available in the table J_1IEWTNUMGR against Company code, Business place and Off Key.
    One more question is whether we need to give Business place or Section code while creating TDS challan using J1INCHLN. It will appear like "Business Place/Section Code" in the screen. If I select from drop down It is taking Section code. Is it possible to change the logic from Section code to Business place.
    Thanks & Regards

  • The best place for content server

    Hello,
    We need to install content Server . SAP ECC is in Paris .
    The users who will use the content server will be in New-York.
    Is the best place for content server in Paris or in New-York?
    The question could be : Will a document (for ex. a pdf of 100 Mb) to be checked_in the CS be first transferred from frontend to ECC and then from ECC to CS or directly from frontend to content server ?
    Thanks

    Hi Oda,
    If your users are in New-York, then better to have content server there to optimize network traffic and speed. There is something called as distributed content server concept where you can have different storage areas for different geographical locations.
    And as far as i know, whenever files are checked-in, they are directly stored in content server and it will not route through the ECC. Only DIR stored in the ECC will be linked to the file in the content server.
    Hope this helps.
    Regards,
    Ravi

  • Changing decimal places for currencies

    Hi everyone,
    I'm a complete begginer to SAP BI and I need to change a value in SPRO > General Settings > Currencies > Set Decimal Places for Currencies, but the option that I want doesn't exist.
    I need to add a new entry with the value: currency - EUR6 and decimals 6, but there is no 6 available. Can anyone tell me where can I add this or what is the table where this information is???
    Thanks in advance!
    Rogério Brá

    ok I think it works - just try and play
    This is what I did (sort of same scenario - if you get my drift)
    Currency Key MGF - translation ratio 1000:1
    Exchange rate is : 11:02750 to the Euro
    Invoice entered for 1,000,000.00
    Currency calculated as 90.68 eur
    (ie 1,000,000/(11.02750 * 1000))
    You can play aroudn with direct/indirect to ge the factors right
    But it works (I thought it did - I am qualified FICO honest!!)
    This wont get you around displaying 6 decimals - BUT it will help with currency conversion

  • Decimal places  for qualitative characterstics in inspection lot

    i have lot quantity with decimal (i.e 2.5 Ltr),and lot is generated for 01 type inspection type,But we have assigned MIC's as qualitative characterstics,While result recording the MIC's are  either accepted are rejected,for this in RRecording,I am entering the quantity 1.5Ltr Accepted and 1Ltr Rejected ,But system not allows me to enter Decimal places.
    Now My question is why system not accepted the quantity but lot Quantity is in Decimal.
    I know for qualitative character is attribute,it cannot accept the Decimal places,But we have assinged an inspection point to generate a rejection leter for above quanity. The Rej Letter fetches the data from resul recording.
    can give any suggestion to enter decimal places in Resul recording.

    Now My question is why system not accepted the quantity but lot Quantity is in Decimal.
    In simple words Lot Qty is derived in inspection lot from the PO or GR qty whereas  sample Qty or individual sample Qty is derived from the sampling procedure attached to a individual char.
    Now As you rightly understood that for attribute char you really can not enter the decimal.what can be done is as you wrote >"the Rej Letter fetches the data from result recording">you can make the enhancement in the Letter fetching data like  1.5Ltr Accepted and 1Ltr Rejected 
    or
    make enhancement & update table with  User Exit :---->QEEM0003 User exit: add. functions after valuating insp. characs 
    I hope this may throw some light
