Extend Data Structure
Hi..
I want to add some fields into data structure 0FI_AP_3.
With this data structure , extract structure named DTFIAP_3 is there. I have added the fields into this extend structure. But when I m using the RSA3 these fields are not appearing there.
Please suggest me.
Thanks a lot.
Pankaj Angra
Hi Pankaj ,
After adding the fields you have to unhide the added fields in T-Code RSA6 for the data source 0FI_AP_3 by removing hide check box . Have you done that? .
If you have done this and still fields are not appering in RSA3 you can go to the path settings->Layout->Current and move your added fields from right to left so that layout displays the added fields.

Edited by: amulya chowdary on Jan 22, 2008 6:34 AMHi
Iam providing the necessary configuration steps for New G/L
1Define Currencies for Leading Ledger:
Financial Accounting (New)>**** (New)>Ledgers>Ledger>Define currencies of The leading ledger
2.Define Ledger for General Ledger Accounting
F/A (New) > ****/ (New) > Ledgers >Ledger > Define Ledgers for General Ledger Accounting
3.Assigning Scenarios to Ledger
Financial Accounting (New)>**** (New)>Ledgers>Ledger>Assign scenarios & Customer fields to ledger
Following Predefined Scenarios is assigned to the Non leading Ledger
Cost Centre
Preparation for Consolidation
Business Area
Profit Centre Update
Segmentation
Cost of Sales Accounting
4.Define and activate Non Leading Ledger:
Financial Accounting (New)>****(New)>Ledgers>Ledger> Define and activateNon Leading Ledger
5. Defining Segment
Enterprise Structure>Definition>Financial Accounting >Define segment
We will assign this segment in the Normal Profit Centre
Hence we will be getting reports for Segment 001
6. Activate Document Splitting:
FA(N)>GLA(N) Business Transactions> Doc.Splitting >Activate Doc Splitting
Spl Note: Always see that the tick is on inheritance
7.Classify G/L Accts for Document Splitting:
Financial Accounting (New)>General Ledger Accounting (New)>Business Transactions>Document splitting> Classify G/L Accts for Document Splitting
For the G/L created in the Company Code , Give from and to and give the category to which, The G/L Belongs
What ever G/L account is created we have select the category from the predefined Groups in the system
8.Classify Document Types for Document Splitting:
Financial Accounting (New)>General Ledger Accounting (New)>Business Transactions>Document Splitting> Classify Documents Types for Document
Here No Changes are done, only standard setting is followed.
Standard Documents Types are predefined by SAP, No configuration changes need been made in this configuration step.
9.DEFINE DOCUMENT SPLITTING CHARACTERISTICS FOR GENERAL LEDGER ACCOUNTING:
Financial Accounting (New)>General Ledger Accounting (New)>Business Transactions>Document splitting>Define Doc Splitting Characteristic for General Ledger Accounting
Here we have to define, Document Splitting Characteristics like
Business Area,
Profit center and
Segment
10.Define Zero Balancing Clearing Account:
Financial Accounting (New)>General Ledger Accounting (New)>Business Transactions>Document splitting>Define Zero Balance Clearing Account
Enter the G/L Acct which we have created for Zero BAL Clearing Accts
Save It
11.DEFINE DOCUMENT SPLITTING CHARACTERISTICS FOR CONTROLLING.
Financial Accounting (New)>General Ledger Accounting (New)>Business Transactions>Document splitting>Define Doc Splitting Characteristic for Controlling
Here we are defining Cost Centre as: Doc Splitting Characteristic for Controlling.
12.FI- Co Real Time Integration
Financial Accounting (New)>**** (New)>ledgers>real time integration of Controlling with financial Accounting>Define variants for Real time integration
In this IMG activity, you define variants for the real-time integration of Controlling (CO) with Financial Accounting (FI).
13.Assign variants for Real Time Integration to Company Codes:
Financial Accounting (New)>**** (New)>ledgers>real time integration of Controlling with financial Accounting>Assign variants for Real time integration to Co Codes
Here we have to assign the variant to our company code.

Extending vs. Using Data Structures
I'm fairly new to Java, though not to coding in general, and I'm wondering, whether its better to extend a data structure or to use one, when creating a class.
For example, I've been messing around with some playing cards, and to make the deck, I essentially want to use a stack. Would it be better to create a Deck class that extends Stack, or to create a Deck class that contains a Stack object and methods that modify the Stack? I've tried it both ways, and they both seem to do okay, but I'm wondering which way is preferable.
So far, inheriting seems more powerful, but using is much cleaner. (e.g. I don't have to worry about them calling pop() instead of draw())
Edited by: chess19 on Mar 16, 2009 6:19 PMYou seem to be on track in terms of the issues involved. If you google for the phrase "prefer composition to inheritance" you'll find a lot of people with relevant advice.

OC4J: marshalling does not recreate the same data structure onthe client
Hi guys,
I am trying to use OC4J as an EJB container and have come across the following problem, which looks like a bug.
I have a value object method that returns an instance of ArrayList with references to other value objects of the same class. The value objects have references to other value objects. When this structure is marshalled across the network, we expect it to be recreated as is but that does not happen and instead objects get duplicated.
Suppose we have 2 value objects: ValueObject1 and ValueObject2. ValueObject1 references ValueObject2 via its private field and the ValueObject2 references ValueObject1. Both value objects are returned by our method in an ArrayList structure. Here is how it will look like (number after @ represents an address in memory):
Object[0] = com.cramer.test.SomeVO@1
Object[0].getValueObject[0] = com.cramer.test.SomeVO@2
Object[1] = com.cramer.test.SomeVO@2
Object[1].getValueObject[0] = com.cramer.test.SomeVO@1
We would expect to see the same (except exact addresses) after marshalling. Here is what we get instead:
Object[0] = com.cramer.test.SomeVO@1
Object[0].getValueObject[0] = com.cramer.test.SomeVO@2
Object[1] = com.cramer.test.SomeVO@3
Object[1].getValueObject[0] = com.cramer.test.SomeVO@4
It can be seen that objects get unnecessarily duplicated â“ the instance of the ValueObject1 referenced by the ValueObject2 is not the same now as the instance that is referenced by the ArrayList instance.
This does not only break referential integrity, structure and consistency of the data but dramatically increases the amount of information sent across the network. The problem was discovered when we found that a relatively small but complicated structure that gets serialized into a 142kb file requires about 20Mb of network communication. All this extra info is duplicated object instances.
I have created a small test case to demonstrate the problem and let you reproduce it.

The parameters you might be interested in playing with are HARDCODE_SERIALISATION and TEST_SIZE defined at the beginning of RMITestApplication.java. The HARDCODE_SERIALISATION is a flag that specifies whether Java serialisation should be used to pass the data across or we should rely on OC4J marshalling. TEST_SIZE defines the size of the object graph and the ArrayList structure. The bigger this size is the more dramatic effect you get from data duplication.
The test case outputs the structure both on the server and on the client and prints out the size of the serialised structure. That gives us sufficient comparison, as both structure and its size should be the same on the client and on the server.
The test case also demonstrates that the problem is specific to OC4J. The standard Java serialisation does not suffer the same flaw. However using the standard serialisation the way I did in the test case code is generally unacceptable as it breaks the transparency benefit and complicates interfaces.
To run the test case:
1) Modify provider URL parameter value on line 15 of the RMITestApplication.java for your environment.
2) Deploy the bean to the server.
4) Run RMITestApplication on a client PC.
5) Compare the outputs on the server and on the client.
I hope someone can reproduce the problem and give their opinion, and possibly point to the solution if there is one at the moment.

AlexeiHi,
Eugene, wrong end user recovery. Alexey is referring to client desktop end user recovery which is entirely different.
Alexy - As noted in the previous post:
http://social.technet.microsoft.com/Forums/en-US/bc67c597-4379-4a8d-a5e0-cd4b26c85d91/dpm-2012-still-requires-put-end-users-into-local-admin-groups-for-the-purpose-of-end-user-data?forum=dataprotectionmanager
Each recovery point has users permisions tied to it, so it's not possible to retroacively give the users permissions. Implement the below and going forward all users can restore their own files.
This is a hands off solution to allow all users that use a machine to be able to restore their own files.
1) Make these two cmd files and save them in c:\temp
2) Using windows scheduler – schedule addperms.cmd to run daily – any new users that log onto the machine will automatically be able to restore their own files.
<addperms.cmd>
Cmd.exe /v /c c:\temp\addreg.cmd
<addreg.cmd>
set users=
echo Windows Registry Editor Version 5.00>c:\temp\perms.reg
echo [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent\ClientProtection]>>c:\temp\perms.reg
FOR /F "Tokens=*" %%n IN ('dir c:\users\*. /b') do set users=!users!%Userdomain%\\%%n,

Is there an easy way to select Items randomly from a data structure?
Put simply, I want to implement a "bag" data structure. So, when i select an item I don't know which one i'm going to get. I want to be able to select all the items once (so no replacing of items i.e. selecting the same item twice in one session).
I can think of ways to implement it using random number generators and the like but does anyone know of a simple datastructure that will encapsulate this "bag" functionality and make my life simple. Hash tables maybe? Any pointers appreciated.
Chris.I don't think there is anything like this in the collections framework but writing one as an extension of a vector could be simple. Something like:
public class Bag extends Vector {
private Random _random = new Random();
public Object pickRandom() {
return this.remove(this._random.nextInt(this.size()));
}To add objects to the bag you just use the add(Object o) method (specified by the List interface, implemented by Vector). To "grab" one just call pickRandom(). -
Bit shifting tricks and speeding up data structure
I'm pretty new to working directly with bits, but it is a lot of fun. I'm converting a javascript data structure to Flash.
So I'm thinking that Math.floor(uint/32) is the same as uint >> 5, right?
And that uint % 32 is the same as uint & 31 ? Evidently this works for modulos that are powers of 2, what a cool trick.
Using both of those cut the time needed for storing and retrieving data about in half.
But it is still takes about three times longer that just using the native Object. This is in reference to my previous post http://forums.adobe.com/message/5001353#5001353 but that didn't get very far.
So if anybody has any suggestions on how else to speed this up it would be very helpful:

return a&0xffffffff;the math shortcuts, as mentioned above, have a greater benefit. (and thanks. yes, that's from a book i wrote,
Flash Game Development: In A Social, Mobile and 3D World
Math Class Shortcuts
These methods actually do provide a benefit and that benefit can be significant even without needing millions of operations to realize. They are listed in alphabetical order starting with Math.abs. (See support files/Chapter 07/math_class/Math.abs_v_conditional.fla, support files/Chapter 07/math_class/Math.floor_v_int.fla etc.)
Math.abs
Using
x = (y<0) ? -y: y;
instead of
x = Math.abs(y)
is about twice as fast. Unless you are using millions of Math.abs operations, you should not expect a noticeable benefit from using the inline code. In addition, the inline code is cumbersome.
var xx:int;
var n:int = 10000000;
var n2:int = n/2;
var i:int;
var startTime:int = getTimer();
//// Math.abs duration: 1016
for(i=0;i<n;i++){
xx = Math.abs(n2-i);
trace("Math.abs duration:",getTimer()-startTime);
// conditional duration: 445
startTime = getTimer();
for(i=0;i<n;i++){
xx = (n2-i<0) ? i-n2 : n2-i;
trace("conditional duration:",getTimer()-startTime);
Math.ceil and Math.floor
Using
x = int(y);
Instead of
x = Math.floor(y); // y>=0
x = Math.ceil(y); // y<=0
Is about twice as fast. Unless you are using millions of Math.floor operations (with non-negative numbers), you should not expect a noticeable benefit.
var i:int;
var n:int = 10000000;
var xx:int;
var startTime:int = getTimer();
// Math.floor duration: 1105
for(i=0;i<n;i++){
xx = Math.floor(i/n);
trace("Math.floor duration:",getTimer()-startTime);
// int duration: 479
startTime = getTimer();
for(i=0;i<n;i++){
xx = int(i/n);
trace("int duration:",getTimer()-startTime);
Math.max
Using
x = (i>j) ? i : j;
instead of
x = Math.max(i,j);
is about twice as fast.
This shortcut is also cumbersome but has the greatest benefit (along with Math.min) of all those listed in this section. Notice the difference in time required to execute the code blocks and how few iterations are needed to demonstrate that difference.
var xx:int;
var n:int = 1000;
var i:int;
var j:int;
var startTime:int;
// Math.max duration: 109
startTime = getTimer();
for(i=n-1;i>=0;i--){
for(j=n-1;j>-0;j--){
xx = Math.max(i,j);
trace("Math.max duration:",getTimer()-startTime);
// conditional duration 43
startTime = getTimer();
for(i=n-1;i>=0;i--){
for(j=n-1;j>-0;j--){
xx = (i>j) ? i : j;
trace("conditional duration",getTimer()-startTime);
Math.min
Using
x = (i<j) ? i : j;
instead of
x = Math.min(i,j);
is about twice as fast.
This shortcut is also cumbersome but has the greatest benefit (along with Math.max) of all those listed in this section. Notice the difference in time required to execute the code blocks and how few iterations are needed to demonstrate that difference.
var xx:int;
var n:int = 1000;
var i:int;
var j:int;
var startTime:int;
// Duration Math.min 121
startTime = getTimer();
for(i=0;i<n;i++){
for(j=0;j<n;j++){
xx = Math.min(i,j);
trace("Duration Math.min",getTimer()-startTime);
// Duration conditional 43
startTime = getTimer();
for(i=0;i<n;i++){
for(j=0;j<n;j++){
xx = (i<j) ? i : j;
trace("Duration conditional",getTimer()-startTime);
Math.pow
It is two to three times faster to explicitly multiply a number variable compared to using Math.pow. That benefit even extends a little beyond integer exponents because Math.sqrt(i) is about twice as fast as Math.pow(i,.5).
var i:int;
var n:int = 10000000;
var xx:int;
var startTime:int;
// exp .5: 2020, exp 2: 1533, exp 3: 1617, exp 4: 1427, exp 5: 1381, exp 10: 1391
startTime = getTimer();
for(i=0;i<n;i++){
xx = Math.pow(i,.5);
trace("Duration Math.pow",getTimer()-startTime);
// exp .5: 1064, exp 2: 427, exp 3: 778, exp 4: 557, exp 5: 501, exp 10: 586
startTime = getTimer();
for(i=0;i<n;i++){
xx = Math.sqrt(i);
trace("Duration iteration",getTimer()-startTime); -

simple transformation to accommodate these possibilities?
2. In trying to accommodate the "zero or more times" case, I am trying
to use the <tt:loop> instruction. It occurs several layers deep in the
XML hierarchy, but at the top level of the ABAP table. The internal
table has a structure defined in the ABAP program, not in the data
dictionary. In the simple transformation, I used <tt:type> and
<tt:node> to define the structure of the internal table and then
tried to use <tt:loop ref="ROOT2" name="line"> around the subtree that
can occur zero or more times. But every variation I try seems to get
different errors. Can anyone supply a working example of this?
3. Among the fields in the internal table, I've defined three
one-character fields named TYPE_CSV, TYPE_XLS, and TYPE_PDF. In the
XML file, I expect zero to three elements of the form
<ExportType exporttype='csv' />
<ExportType exporttype='xls' />
<ExportType exporttype='pdf' />
I want to set field TYPE_CSV = 'X' if I find an ExportType element
with its exporttype attribute set to 'csv'. I want to set field
TYPE_XLS = 'X' if I find an ExportType element with its exporttype
attribute set to 'xls'. I want to set field TYPE_PDF = 'X' if I find
an ExportType element with its exporttype attribute set to 'pdf'. How
can I do that?
4. For an element that has a value like
<ErrorCode>123</ErrorCode>
in the simple transformation, the sequence
<ErrorCode> <tt:value ref="ROOT1.CODE" /> </ErrorCode>
seems to work just fine.
I have other situations where the XML reads
<IsNew value='true' />
I wanted to write
<IsNew>
<tt:value ref="$line.IS_NEW"
map="val(' ') = xml('false'), val('X') = xml('true')" />
</IsNew>
but I'm afraid that the <tt:value> fails to deal with the fact that in
the XML file the value is being passed as the value of an attribute
(named "value"), rather than the value of the element itself. How do
you handle this?Try this code below:
data l_xml_table2 type table of xml_line with header line.
W_filename - This is a Path.
if w_filename(02) = '
open dataset w_filename for output in binary mode.
if sy-subrc = 0.
l_xml_table2[] = l_xml_table[].
loop at l_xml_table2.
transfer l_xml_table2 to w_filename.
endloop.
endif.
close dataset w_filename.
else.
call method cl_gui_frontend_services=>gui_download
exporting
bin_filesize = l_xml_size
filename = w_filename
filetype = 'BIN'
changing
data_tab = l_xml_table
exceptions
others = 24.
if sy-subrc <> 0.
message id sy-msgid type sy-msgty number sy-msgno
with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif. -

Can I automate the creation of a cluster in LabView using the data structure created in an auto generated .CSV, C header, or XML file? I'm trying to take the data structure defined in one or more of those files listed and have LabView automatically create a cluster with identical structure and data types. (Ideally, I would like to do this with a C header file only.) Basically, I'm trying to avoid having to create the cluster by hand, as the number of cluster elements could be very large. I've looked into EasyXML and contacted the rep for the add-on. Unfortunately, this capability has not been created yet. Has anyone done something like this before? Thanks in advance for the help.

Is this something you're trying to do at runtime? Clusters are fixed data structures so you can't change them programmatically. Or, are you just trying to create some typedef cluster controls so that you can use them for coding? What would your clusters basically look like? Perhaps another way of holding the information like an array of variants?
You can try LabVIEW scripting, though be aware that this is not supported by NI.
Wow! Thanks for the quick response! We would use this cluster as a fixed data structure. No need to change the structure during runtime. The cluster would be a cluster of clusters with multiple levels. There would be not pattern as to how deep these levels would go, or how many elements would be in each. Here is the application. I would like to be able to autocode a Simulink model file into a DLL. The model DLL would accept a Simulink bus object of a certain data structure (bus of buses), pick out which elements of the bus is needed for the model calculation, and then pass the bus object. I then will take the DLL file and use the DLL VI block to pass a cluster into the DLL block (with identical structure as the bus in Simulink). To save time, I would like to auto generate the C header file using Simulink to define the bus structure and then have LabView read that header file and create the cluster automatically. Right now I can do everything but the auto creation of the cluster. I can manually build the cluster to match the Simulink model bus structure and it runs fine. But this is only for an example model with a small structure. Need to make the cluster creation automated so it can handle large structures with minimal brute force. Thanks! -
What is the best data structure for loading an enterprise Power BI site?
Hi folks, I'd sure appreciate some help here!
I'm a kinda old-fashioned gal and a bit of a traditionalist, building enterprise data warehouses out of Analysis Service hypercubes with a whole raft of MDX for analytics. Those puppies would sit up and beg when you asked them to deliver up goodies
to SSRS or PowerView.
But Power BI is a whole new game for me.
Should I be exposing each dimension and fact table in the relational data warehouse as a single Odata feed?
Should I be running Data Management Gateway and exposing each table in my RDW individually?
Should I be flattening my stars and snowflakes and creating a very wide First Normal Form dataset with everything relating to each fact?
I guess my real question, folks, is what's the optimum way of exposing data to the Power BI cloud?
And my subsidiary question is this: am I right in saying that all the data management, validation, cleansing, and regular ETTL processes are still required
before the data is suitable to expose to Power BI?
Or, to put it another way, is it not the case that you need to have a clean and properly structured data warehouse
before the data is ready to be massaged and presented by Power BI?
I'd sure value your thoughts and opinions,
Cheers, Donna
Donna KellyDear All,
My original question was:
what's the optimum way of exposing data to the Power BI cloud?
Having spent the last month faffing about with Power BI – and reading about many people’s experiences using it – I think I can offer a few preliminary conclusions.
Before I do that, though, let me summarise a few points:
Melissa said “My initial thoughts: I would expose each dim & fact as a separate OData feed” and went on to say “one of the hardest things . . . is
the data modeling piece . . . I think we should try to expose the data in a way that'll help usability . . . which wouldn't be a wide, flat table ”.
Greg said “data modeling is not a good thing to expose end users to . . . we've had better luck with is building out the data model, and teaching the users
how to combine pre-built elements”
I had commented “. . . end users and data modelling don't mix . . . self-service so
far has been mostly a bust”.
Here at Redwing, we give out a short White Paper on Business Intelligence Reporting. It goes to clients and anyone else who wants one. The heart
of the Paper is the Reporting Pyramid, which states: Business intelligence is all about the creation and delivery of actionable intelligence to the right audience at the right time
For most of the audience, that means Corporate BI: pre-built reports delivered on a schedule.
For most of the remaining audience, that means parameterised, drillable, and sliceable reporting available via the web, running the gamut from the dashboard to the details, available on
demand.
For the relatively few business analysts, that means the ability for business users to create their own semi-customised visual reports when required, to serve
their audiences.
For the very few high-power users, that means the ability to interrogate the data warehouse directly, extract the required data, and construct data mining models, spreadsheets and other
intricate analyses as needed.
On the subject of self-service, the Redwing view says: Although many vendors want tot sell self-service reporting tools to the enterprise, the facts of the matter are these:
v
80%+ of all enterprise reporting requirement is satisfied by corporate BI . . . if it’s done right.
v Very few staff members have the time, skills, or inclination to learn and employ self-service business intelligence in the course of their activities.
I cannot just expose raw data and tell everyone to get on with it. That way lies madness!
I think that clean and well-structured data is a prerequisite for delivering business intelligence.
Assuming that data is properly integrated, historically accurate and non-volatile as well, then I've just described
a data warehouse, which is the physical expression of the dimensional model.
Therefore, exposing the presentation layer of the data warehouse is – in my opinion – the appropriate interface for self-service business intelligence.
Of course, we can choose to expose perspectives as well, which is functionally identical to building and exposing subject data marts.
That way, all calculations, KPIs, definitions, and even field names, and all consistent because they all come from the single source of the truth, and not from spreadmart hell.
So my conclusion is that exposing the presentation layer of the properly modelled data warehouse is – in general - the way to expose data for self-service.
That’s fine for the general case, but what about Power BI? Well, it’s important to distinguish between new capabilities in Excel, and the ones in Office 365.
I think that to all intents and purposes, we’re talking about exposing data through the Data Management Gateway and reading it via Power Query.
The question boils down to what data structures should go down that pipe.
According to
Create a Data Source and Enable OData Feed in Power BI Admin Center, the possibilities are tables and views. I guess I could have repeating data in there, so it could be a flattened structure of the kind Melissa doesn’t like (and neither do I).
I could expose all the dims and all the facts . . . but that would mean essentially re-building the DW in the PowerPivot DM, and that would be just plain stoopid. I mean, not a toy system, but a real one with scores of facts and maybe hundreds of dimensions?
Fact is, I cannot for the life of me see what advantages DMG/PQ
has over just telling corporate users to go directly to the Cube Perspective they want, that has already all the right calcs, KPIs, security, analytics, field names . . . and most importantly, is already modelled correctly!
If I’m a real Power User, then I can use PQ on my desktop to pull mashup data from the world, along with all my on-prem data through my exposed Cube presentation layer, and PowerPivot the
heck out of that to produce all the reporting I’d ever want. It'd be a zillion times faster reading the data directly from the Cube instead of via the DMG, as well (I think Power BI performance sucks, actually).
Of course, your enterprise might not
have a DW, just a heterogeneous mass of dirty unstructured data. If that’s the case,
choosing Power BI data structures is the least of your problems! :-)
Cheers, Donna

Lease Out Contract - Master Data Structural Relations
Dear Gurus,
I am new to FX RE and if my question is too simple, please excuse me!
I am researching the possibilities for the master data structure of lease in contracts and have a serious confusion.
The documentation says that objects can be assigned to a contract individually or many objects related to one contract. At the same tim it is said that rental units are assigned only to lease out contracts.
How should i proceed if my company has got many lease in contracts for different object. Is it a must the contract to be assigned to an object or it can be managed just as a contract? I saw that from the RE Navigator you can create a contract, does that mean that in FX RE the contracts itself is considered as master data record?
Any opinions will be highly appreciated.
Many thanks in advance!Dear Kumar,
Sorry if I ve been confusing. I will try to make it more clear.
I am working for a Teleco and i am researching the possibility of implementing FX - RE internally. We will not need all the functionalities of the module, but only the ones that allow you to manage your lease in contracts. We`ve got lots of base stations contracts (as you can imagine) where our company is a tenant in a lease contract.
I did some research in relation to the master data structure and cant work out how should our master data be structured. The business requirements are - handling the advance payments, accruals and postings, giving and receiving notices, adjustments of rent etc. Is it possible to create the contract within the system, set all the conditions directly in it or do we need to have another master record other that the contract itself.
My confusion comes from the fact that the standard solution of the lease outs suggests creating a rental unit first and then assigning the contract to it. But since we will be tenants we dont need to more detailed information on these objects, we just need the conditions in the contract that will let us handle all the activities that arise in connection to it.
I hope that i put the question more clearly this time.
Can you also tell me if it is possible to create a template and after entering the conditions about the particular contract to generate it from the system on a hard copy?
Many thanks and sorry if i cant make myself more clear! -
Urgent! Need help in deciding data structure to use
Hi all,
I need to implement a restaurant system by which a customer can make a reservation.
I was wondering whether vector would be able to be store such an object, The thing is I don't want a complex data structure. just sumthin simple cos i hardly have anytime left to my submission. sighz...
The thing is I need to able to search based on 2 properties of an object. Eg. I need to search for a reservation based on the customer name and the date he reserved a table.

What's the easiest way to move app data and data structures to a server?
Hi guys,
I've been developing my app locally with Apex 4.2 and Oracle 11g XE on Windows 7. It's getting close to the time to move the app to an Oracle Apex server. I imagine Export/Import is the way to move the app. But what about the app tables and data (those tables/data like "customer" and "account" created specifically for the app)? I've been using a data modeling tool, so I can run a DDL script to create the data structures on the server. What is the easiest way to move the app data to the server? Is there a way to move both structures and data in one process?
Thanks,
KimThere's probably another way to get here, but, in SQL Developer, on the tree navigation, expand the objects down to your table, right click, then click EXPORT.. there you will see all the options. This is a tedious process and it sucks IMO, but yeah, it works. It sucks mostly because 1) it's one table at a time, 2) if your data model is robust and has constraints, and sequences and triggers, then you'll have to disable them all for the insert, and hope that you can re-enable constraints, etc without a glitch (good luck, unless you have only a handful of tables)
I prefer using the oracle command line EXP to export an entire schema, then on the target server I use IMP to import the schema. That way, it's near exact. This makes life messy if you develop more than one application in a single schema, and I've felt that pain -- however -- it's a whole lot easier to drop tables and other objects than it is to create them! (thus, even if the process of EXP/IMP moved more than you wanted to "move".. just blow away what you don't want on the target after the fact..)
You could use oracle's datapump method too.
Alternatively, what can be done, IF you have access to both servers from your SQL developer instance (or if you can tnsping them both already from the command line, you can use SQL*PLUS), is run a script that will identify your apex apps' objects (usually by prefix to object names, like EBA_PROJ_%, etc) and do all the manual work for you. I've created a script that does exactly this so that I can move data from dev to prod servers over a dblink. It's tricky because of the order that must be executed to disable constraints and then re-enable them, and of course, trickier if you don't consistently prefix ALL of your "application objects"... (tables, views, triggers, sequences, functions, procs, indexes, etc) -
Dictionary Structure---data structure of Dictionary
I don't know how to build a data structure of dictionary...
somebody said it's was built by binary tree. but I don't know how.
somebody helps me????
thanks for reading my topicA dictionary is not a tree/hierarchical structure. Have you ever opened a dictionary before?! If you have even once, you already know the structure of a dictionary. Now, how to build that in Java is another question. I'm not sure of your requirements but you could start by creating an object that represents a single term, it's definitions, usages, etc. Then you can create a List of them (and sort them alphabetically). Simple enough?

SAP ABAP Proxy - recursive data structure problem
Hi,
For our customer we try to bind SAP with GW Calendar using GW Web Services. We tried to generate ABAP Proxy from groupwise.wsdl file but there are problems: GW uses recursive data structures what ABAP Proxy can not use. Is there any simple solution to this problem?
Best regards
PawelAt least I don't have a clue about ABAP Proxy.
