TxDataSource needed for flat transactions?

Hi all,
I have a question about TxDataSource. I've read that TxDataSource have more overhead
then plain DataSource. Is it better to use plain DataSources -IF- I don't use
distributed transactions in my EJB/JSP ? I think I could simply switch to TxDataSource
if in the future out app will involve new DB resources.....
thanks

FrancescoIf you want EJB transactional semantics, you must use a TxDataSource. It's not any slower
than a regular DataSource, except where it has to, to provide the transactional guarantees.

  • Highest security needed for banking transactions

    I am new to my Linksys wireless WRT160NV2 router and I'd like someone to assure me of the safety in using the router for banking transactions.  It's in my home, and I only bought it so my son could connect video game platforms wirelessly. 
    My computer is connected by wire to one of the WRT160's ethernet ports.  I'm hoping this is more secure. 
    This may be a stupid question, but can anyone tell me if a hacker can use the wireless connection (assuming he can get through WPA encryption) to access my wired computer.  I need absolute security with banking transactions.  Put another way, is my wired computer just as safe as before having the wireless router?

    The quick answer for you is 'yes'.  However, the chances of it occurring is not even slim... but none.  If you think there are people driving around aimlessly stiffing out networks in your neighborhood from their car trying to break the security to get to your computer.... well, it's just not happening.   There are plenty of unsecured networks around, in parking lots, Starbucks and whatever, they can just get on there.  WEP has been broken, WPA has been broken.  I have never read anything anywhere where someone has got on a secured network, by breaking the security code and stole data from the average person.  Your wireless has to transmit about a 1Mb burst that they have to capture in order to start the decoding.
    The only reason people break the security is that it's a challenge to them and fun.  I just use WEP, MAC address filtering (which can be spoofed also), software firewall and the routers firewall.  Heck, my share drives aren't even passworded.
    In my neighborhood, there are seven wireless networks of which four are unsecured.  The crooks will like them before anyone else.  
    Bottom line... don't even worry about it.

  • Which Airport card do I need for an iMac G4 Flat Screen 15"?

    Hi, I have an iMac G4 (flat screen, with silver arm and round base), 15".
    I'd be extremely grateful if someone could let me know which Airport card I need for this Mac and also whether or not I also require an adaptor. I have looked this up on the Apple site and also in 'The Flatscreen iMac for Dummies' book (I'm a complete technophobe, I'm afraid!), but am none the wiser.
    If possible, model numbers for the Airport card and adaptor that I do need would be much appreciated.
    Many thanks,
    Jeremy

    Choose About this Mac from the Apple menu and click on More Info, or if you're running Mac OS 9, choose Apple System Profiler from the Apple menu. Check the speed of the computer's CPU; if it is below 1GHz, you need the regular AirPort card, with the AirPort Extreme card being used on newer iMacs. No iMac G4 requires an adaptor to use an AirPort card.

    Could anybody help me in this. And which BDC method is best for this scenario.

    Hi
    The COMMIT before and after CALL TRANSACTION is useless, The transaction FB01 calls the commit by itself, so u need only:
    CALL TRANSACTION 'FB01' USING BDC_TAB
                                                   MODE 'N'
                                                   UPDATE 'S'
                                                   MESSAGE ITAB.
    Now ITAB is like structure BDCMSGCOLL, so after CALL Transaction u can use message statament in order to show a popup with message:
    CALL TRANSACTION 'FB01' USING BDC_TAB
                                                   MODE 'N'
                                                   UPDATE 'S'
                                                   MESSAGE ITAB.
    LOOP AT ITAB.
    MESSAGE ID ITAB-MSGID TYPE 'I' NUMBER ITAB-MSGNR
             WITH ITAB-MSGV1 ITAB-MSGV2 ITAB-MSGV3 ITAB-MSGV4.

  • Need help on BDC  for MB1A transaction.

    Hello Abapers,
    I need to create a BDC for t-code MB1A to do the Goods Issue with reference to reservation.
    I am not able to use the BAPI 'BAPI_GOODSMVT_CREATE' to do the goods issue as there are some additional functionalities (Stock Determination) to be included.
    The problem I am facing is, The stock determination will determine the Quantity, Storage Location and Valuation type for every item of the reservation. The quantity will be picked up from multiple storage locations and as a result the line item of reservation will be split into two or more for Goods Issue.
    When this happens, If the reservation is having multiple line items, tracking the next item becomes a problem.
    Please suggest a way to approach this problem.
    Usefull answers will be rewarded.
    Thanks in Advance,
    Vinutha.

    Hi  ABAPERS
    i am new for BDC i want to know how the flat file format for call transaction execution.
    if any one have sample flat file data for any transaction please send me.

    Hi,
    The file format differ for different transaction. Basically you can have the field in any order. It matters how you upload into SAP. Use the function module GUI_UPLOAD to upload the flat file.
    Please see this sites for more info.

  • Need to know Objects Linking for MM Transactions MIGO & ML81N

    We have a typical requirement to store & retrieval of Inspection Records / Reports which were used during Goods Receipt in MM i.e QA32 / or MIGO  Transaction & also at service Entry Sheet i.e ML81N  ( MM Transaction ).
    Can anyone help how can we achieve this as we are implementing DMS in ECC 6.0 on EHP 5.
    The purpose is to store Quality Inspection records while doing Goods inspection in QA32 , & same is doing while passing service entry sheet  ML81n. At any time in future we would be able to pull out soft / PDF copy of inspection reports as certified by Quality dept.

    Hi Umesh,
    Please note that SAP DMS doesn't extend any object linking feature for MIGO transaction.A better approach to meet your requirment would be to store documents via Archivelink.The key steps involved are:
    - Content repository definition for Archivelink
    - Document type creation
    -  Assignment of the above document type to MIGO business object BUS2017

  • Accounting entry view needs to be restrcited for STO transactions

    Hi
    There is Stock Transfer scenario at my place. Stock transfer (from one plant to another) is done after adding some profit margin to the cost of material. Note: My different plant represents different profit centers
    Ex: STO is done from plant 1000 to plant 2000. Cost of material is Rs.100 and profit is Rs.20. Hence STO is done at Rs. 120
    Entry posted:
    Stock Plant 2000 (Profit center 2000) - Rs. 120
       To Stock Plant 1000 (Profit center 1000) - Rs 100
       To Profit Margin (Profit center 1000) - Rs. 20
    Now i want that this account entry should not be view by plant 2000 (whose profit center is 2000). Reason is that the management don't want that receiving plant should know about the profit.
    So let me know if i can block the view of accounting entry for plant 2000 for STO transaction only. Plant 2000 should be able view rest all accounting transactions like Purchase from third party, sales, etc.
    Note: For STO transactions, we have created separate PO (Document type) as ZSTO.
    Please help
    Edited by: Deepak Agrawal on Sep 8, 2011 5:58 PM

    Hi,
    You can simply take authorization of GL involving in plant desired. Please ask your BAsis guy to revoke activity 03 against object F_BKPF_BES for authr group of GLs from desired users. It will meet your requirment.

  • Need BDC code for Call Transaction of VL31N, which creates Inbound del.s,

    Hi Experts,
    Is any body does have the BDC (CALL TRANSACTION) code for VL31N transaction, where we can crete INBOUND deliveries from Purc Orders.
    Actually, currently am doing by using FM - GN_DELIVERY_CREATE, but, its not given me a chance to incorporate BATCH SPLIT functionality. So, decided to go with BDC
    1 - Is this VL31N is Okay for BDC, bcoz, some where I red that, since its a ENJOY tx, its NOT recommended?
    2 - Is there any other FM, BAPI to create INBOUND deliveries from POs, which can take care of BATCH SPLIT functionality?
    3 - BDC code for VL31N  tx.

    thanks,
    Romanch

    Hi Romanch,
    You can use the following BTE
    00001321 - CUSTOMER MASTER DATA: Save with Data Transfer
    Also you can check from FIBF Transaction -> Environment -> Infosystem(P/S or Processes) to find the BTE's related to application component.
