How to avoid double logon

Hello experts,
can i avoid that a user is logged in a bsp 2 times (two different pc´s) ?
Is there a standard solution in SAP or is it custom development?

hye Benjimin,
It is not possible to auhenticate single log in through any standard setting. Authetication is bascially initiated from the browse side and hence no real standard setting exists.
This can be achieved only through custom programming.

How to avoid double-click to click-box

Hello,
until now I did not find a solution for this problem:
I have created a training course for a specific application, and in this coure are some click boxes on which the user should click. On many click boxes should the user click only once but if he double-click the click box, in real application nothing happens. There is only one way to succes the action - one click. But in captivate when the user double-click the click box instead of one click it evaluate as success action (the click box is set only to one click, double-click checkbox is not checked).
So my question is, is there any way how to avoid double-click in cases where the user should click only once? Or in case he double-click the click box to show failure caption?
Many thanks.
Lukas

Hi all
Interesting thread. Unfortunately, what would be needed here is some sort of a widget that would run some internal timer. Sure, you can try multiple Click Boxes and configure one with a Single Click and one with a Double Click. But the problem with that (as I see it) is regardless of what you might try, the Single Click will win out every time. Thus you would need a widget of some sort that would "listen" for a Double Click and respond appropriately.
Tough call... Rick

How to avoid database logon dialog on every action of refreshing reports

I am using Crystal reports 208 SP2 and has a database connection to oracle database. Connection is esablished and report retrieves desired data, The problem is when ever i open this report ( which has this connection set) and do a refresh, the report the LogOn dialog pops up.
How to avoid or save this log on info such that it does not pops up the LogOn dialog when i open the report and do a refresh(F5).?

Hi Don,
Thanks for the reply. To try your suggested approach, i need some clarifications .
_Problem summary:for refrence, _
I am following the steps mentioned below to establish a database connection, and fetch the data.
1) I am using Oracle drivers for configuring the ODBC data source. As part of configuration i will specify the Oracle server name
2) In crystal reports, Using "Database" menu, i open "Database Expert" dialog and "Make New connection" by specifing the data source mentioned in step 1). During this process, (ODBC)logon information will be filled in. The user ID and password used has all the rights to access the tables in the database. Logon will be successful and connection is established.
3) Further i use the database table from the "Database Expert" on to the report and refresh(F5) to fetch the data.
After step 3, I close the report and reopen it. Now trying to refresh the database logon dialog pops up. I need to avoid this pop up
Requesting Clarification:;
1) You have specified "When you connect you have the option to use Trusted Authentication, check this option on". Where is this option. Is it in the crystal reports or is it available during data source configuration. Kindly specify.
2) Here "Enterprise logon info that has been configured on the Oracle server." implies the oracle database login information right? If yes, this login details are available and i am using this logon information(i.e. UseriD and Password) during database connection.
If No, Is "Enterprise logon info " is something which should be specifically enabled by DBA in oracle11g configuraion.
Kindly suggest.

How to avoid doubling data

Hi experts,
i loaded a flatfile1 into an ODS and then into an infocube. Again i loaded another flat file2 ( which had the same records as well as few more records as first one) the same way.. when i look at the Infocube, some of the records have double the values. How do i avoid this.. can i go for delta load from ods to infocube..
all the above loads are fulupdate.
Also SDNers,
By full update do we get all the data again if we load from ODS even if we laoded previously.?
thanks
Dave

If you go as Delta from ODS to Cube, ODS will take care in sending only the changed records and the new records.

How to avoid double-counting in Total field

Hi Gurus,
I'm new to Essbase.
Here's a question I don't know how Essbase handle it, my source data stores at relational database, normally one row in the fact table associates with only one row in dimension table, but very common scenario like one fact row can associate with many rows in dimension table, to simplify we have 4 tables:
1. DimProduct(ProductID, ProductName). there's one row like 1, "Bike"
2. FactSales(ProductID, Quantity), there's one row like 1, 10
3. FactSalesReasons(ProductID,ReasonID), there're 2 rows like 1,1 and 1,2 , suppose there're 2 reasons associate with this product sale, that means 1-N relationship between fact and dimension.
4. DimReason(ReasonID,ReasonName), there're 2 rows like 1,"Quality" and 2, "Promotion"
I expect the report as follows:
ProductName ReasonName Quantity
Bike Quality 10
Promotion 10
Total 10
But while built cube, I got the value 20 of Total. I know Microsoft SSAS has a many-many dimension usage can avoid this double counting issue (no need to write extra calculation script), can Essbase do similar way?
Thanks!
Xiao

What I would recommend in this case would be in a calc script. I would guess that this dimension is sparse which usually has a low calculation priority (calcs first and may get overwritten). So, at least for a first pass at a calculation...
========
SET UPDATECALC OFF;
Calc All;
"Total Reason" = @AVG(SKIPNONE,@CHILDREN("Total Reason"));
========
SKIP options are "none", "missing", "zero" or "both".
This will calculate for all accounts.

How to avoid double extension *jpg.tif when exporting layers to files?

Please help, I checked all the topics related and it seems nobody bothers about this issue.
When I do a Photomerge of a series of jpg files, Photoshop builds a multilayered file - but preserves in the name of each layer *.jpg
When I want now to export layers to files, the Scripting function will do the dumb thing and export each file with the original name - ending in JPG - , plus the extension required by me - for ex tif.
It does the same if I chose to export as jpg files and puts double extension again < *.JPG.jpg> at the end of each file exported from a layer.
I looked everywhere and couldn't find a way to solve this behavior, which forces me to do batch renames in Bridge.
The next program where I need the files (After Effects) doesn't want to import these files with double extensions.
Has anyone encountered this issue and what can be done to avoid these double extensions at Scripts/Export layers to files?
Thanks for the answer

I have just altered my script so that it will remove the extentions if found.
http://www.scriptsrus.talktalk.net/Layer%20Saver.htm
Also it would be better to use :-
var layerName = activeDocument.activeLayer.name.replace(/\....$/,'');
As this way it doesn't arbitory remove the last four characters, only if it finds a fullstop.

How to avoid db file parallel read for nestloop?

After upgraded to 11gr2, one job took more than twice as long as before on 10g and 11gr1 with compatibility being 10.2.0.
Same hardware. (See AWR summary below). My analysis points to that Nestloop is doing index range scan for the inner table's index segment,
and then use db file parallel read to read data from the table segment, and for reasons that I don't know, the parallel read is very slow.
AVG wait is more than 300ms. How can I fluence optimier to choose db file sequential read to fetch data block from inner table by tweaking
parameters? Thanks. YD

Its not possible to say anything just by looking at the events.You must understand that statspacks and AWR actualy aggergate the data and than show the results.There may be a very well possibility that some other areas also need to be looked at rather than just focussin on one event.
You have not mentioned any kind of other info about the wait event like their timings and all that.PLease provide that too.
And if I understood your question corretly,you said,
How to avoid these wait events?
What may be the cause?
I am afraid that its not possible to discuss each of these wait event here in complete details and also not about what to do when you see them.Please read teh Performance Tuning book which narrates these wait events and corresponding actions.

How to avoid doubleclick event on a datagrid scrollbars?

Hello.
I've a datagrid.
I need a doubleclick event cliccking on a data grid row.
I've enabled the doubleclick event. It works fine, when the user doubleclicks on a row, an event happens! In my case I open a modal window. Great!
Now the problem:
The problem arises when the user clicks in a short time on a data grid scroll bar (both horizontal or vertical). In this case a double click event is dispatched.
But his intenton is just to scroll the grid, no more.
Please, notice that the dobule click on a scrollbar is a well-known action that can be performed in all the applications and operating systems.
I neet the "double click" event just on a data grid rows and not on its scrollbars. Cliccking twice or more on the scrollbar I just want to scroll the grid. How can avoid to dispatch an event?
Thank you
Pbesi

I was returning today to add something about custom item renderers but you beat me to it, Pbesi. I have a custom gridItemRenderer which I now have to check for just as you demonstrated above. What I don't understand is why I can't just do this:
if( event.target is IGridItemRenderer ) //Should be true for both default and custom
My custom renderer implements the IGridItemRenderer interface, but when I double click one in the grid, the event.target is not myCustomGridItemRenderer, it is GridLayer. So what I have to do is this:
if( (event.target is IGridItemRenderer) || (event.target is GridLayer) )
I presume this would work for all custom gridItemRenderers, but I only have one, so I haven't tested this. Any idea why GridLayer is the type of the event target? My custom renderer is very simple. It just renders Booleans as "Yes/No" rather than "True/False"

try this, may be it will help you.
Example1.java - call the rfc module 'STFC_CONNECTION' with custom definition
of function metadata. Please notice, the communication with static
metadata interface definitions is dangerous. The inconsistencies in the

How to avoid multiple if else using design patterns.

Hi,
Which design patterns is used to avoid lot of if else in our code . Say for example if the user press 1 the out put should be one, if he press 2 it should be two like this upto 10. So we need to include lot of if-else part. How to avoid the multiple if else using design patter for this scenario. I can't find the solution for this problem can you guys help me?.

I'm too lazy to read a whole text book, but the first google link provides a code sample which made me laugh.
http://www.refactoring.com/catalog/replaceConditionalWithPolymorphism.html
double getSpeed() {
    switch (_type) {
      case EUROPEAN:
        return getBaseSpeed();
      case AFRICAN:
        return getBaseSpeed() - getLoadFactor() * _numberOfCoconuts;
      case NORWEGIAN_BLUE:
        return (_isNailed) ? 0 : getBaseSpeed(_voltage);
    throw new RuntimeException ("Should be unreachable");
}My implementation of The Bridge Over The Parrot Shop
package forums;
import java.util.Random;
abstract class Bird {
private static final Random random = new Random();
abstract double getAirSpeed();
public double getBaseSpeed() {
    return randomDouble(18.96);
protected static double randomDouble(double max) {
    return random.nextDouble() * max;
protected static int randomInt(int max) {
    return random.nextInt(max);
class EuropeanSwallow extends Bird {
double getAirSpeed() {
    return getBaseSpeed();
class AfricanSwallow extends Bird {
private int _numberOfCoconuts;
public AfricanSwallow() {
    this(randomInt(4));
public AfricanSwallow(int numberOfCoconuts) {
    _numberOfCoconuts = numberOfCoconuts;
double getAirSpeed() {
    return getBaseSpeed() - getLoadFactor() * _numberOfCoconuts;
public double getLoadFactor() {
    return randomDouble(3.12);
class NorwegianBlue extends Bird {
private boolean _isNailed;
private double _voltage;
public NorwegianBlue() {
    this(randomInt(10)<2, randomDouble(12.0));
public NorwegianBlue(boolean isNailed, double voltage) {
    _isNailed = isNailed;
    _voltage = voltage;
double getAirSpeed() {
    return _isNailed ? 0 : getBaseSpeed(_voltage);
double getBaseSpeed(double voltage) {
    return getBaseSpeed() * (1+(voltage/Math.PI));
public class AirSpeedTest
public static void main(String[] args)
    System.out.println("EUROPEAN: "+new EuropeanSwallow().getAirSpeed());
    System.out.println("AFRICAN: "+new AfricanSwallow().getAirSpeed());
    System.out.println("NORWEGIAN_BLUE: "+new NorwegianBlue().getAirSpeed());
}... and the requisite background for the uninitiated [NORWEGIAN_BLUE|http://www.youtube.com/watch?v=4vuW6tQ0218] and [EUROPEAN v AFRICAN|http://www.youtube.com/watch?v=4b4bGAoVR7g].
You have to know these things when you're a King you know.

How to avoid invalid data entering in LOV through code

hi
1)i have developed lov in table region, but user easily can enter invalid data and saved into the database tables.
2)i created one formvalue and mapping into that return item , still its not working in table region LOV.
3)how to avoid invalid data entering in LOV through code. i have tried this below code in EOimpl set value method. but some how its not wokring.
if (value!=null)
throw new OAAttrValException(OAAttrValException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(),
getPrimaryKey(),
"ProcurementCategory",
getProcurementCategory(),
"FND",
"FND_LOV_SELECT_VALUE");
Thanks.
krish.

Thanks reetesh and gourav for your help.
i followed below mapping details
LOV Item Properties
ID -PurcCommodity
ViewInstance -VendorVO1
ViewObject -PurcCommodity
map1 properties
LOV Region Item - segment1
Return Item -PurcCommodity
CriteriaItem -PurcCommodity
Usefor Validation -Default
map2 properties
LOV Region Item - segment1
Return Item -validation(formvalue)
CriteriaItem -
Usefor Validation -yes
form value properties
ID -validation
ViewInstance -VendorVO1
ViewObject -PurcCommodity
Gourav- i double checked multiple rows it is not working, some times it is not working for single row too.
Thanks
krish.
