Hi
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.
15. Financial Accounting (New)>**** (New) Docs >Define Doc types for General
Ledger View.
16.Financial Accounting (New)>**** (New) Docs > Doc Number Ranges >Define
Doc No Range for GL View.

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 AngraHi 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.

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.

Data Structure for New General Ledger for mySAP 2004
Guys,
We are preparing to upgrade to mySAP 2004.
mySAP 2004 doesn't have data migration tool for upgrade "classic" ledger to new ledger with advanced functionality. To utilize all new functionality, data should be migrated to the new ledger. Data migration tool in this case should be developed (ABAP). What is the difference in data structure of new ledger?
if anybody who already went thru upgrade and could share some examples of programs for mySAP 2004 upgrade, my e-mail : [email protected]
Thanks in advance,
MikeNow I have the same problem. Anyone has a solution for this matter?

What is the new data structure for .RTM files in LV8?
We have software that translates our LV
program to another language. Part of that software package reads RTM
files, decodes them, replaces text, and resaves them. That code is
broken for menus that are saved in LV8+, however. What is the new data
structure?
The simple attached zip file has vi's which
are not ours but serve to illustrate the point. If it's run on an
older RTM file, it correctly outputs and XML version of it, on newer
RTM files it just throws an error.
-- This is the second time I posted this. I was curious what the Solution? icon did on somebody elses post and I apparently marked the whole thread as solved (there should really be an undo on that feature btw --
Attachments:
RunTime_Menu_to_XML.zip 33 KBHi Thomas,
What error are you getting when running the program? I was actually able to run it without errors in LV 8.6.
There are ways to programmatically read and customize RTM files in LabVIEW. I hope that the following links will help:

Error in creating New Data Structures
Hi Gurus,
I tried creating new data structure in the R3 server using RSO2. I was planning to use the Purchasing Table (EKBE). But when I tried saving the structure this error occured/showed.
Invalid Extract sturcture template EKBE of Datasource MM_EKBE
Diagnosis:
You have tried to generate an extract structure with template structure EKBE. This was not successful, because the template structure references quantity or currency fields, for example the field name MENGE from another table.
Procedure:
Generate a view or a DDIC structure based on the template structure, which does not contain the unstupported fields.
- I have no idea what the problem is and what i should do based on the procedure. If anyone can help it would be much appreciated. Thank you in advance
- KITHi Kristian,
The table EKBE has quantity and currency field refernceing field from other table to define them.
You need to include these refenced filed in the structure you add in the data source as the template.
To do this create a custom dictionary object view.
In the view include the refernce currency and quantity field from the reference table.
Also create a join between EKBE and the refernece table using the data elements that are the same.
For example, for quantity key figures in EKBE the unit of measure would be sourced by menge from MARA.
So you need to have table MARA included in the view.
The join would be on the material in EKBE and material in MARA.
You will find reference quantity and currency tab in the table definition in the Reference currency/quantity tab in the table definition.
You need to do this for all your quantity and currency references.
Once that is done use the ZVIEW to create your data source.
Hope it helps,
Best regards,

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

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:

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.

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).

Adding new field to Master Data
Hi All,
I have one master data which is business content.
i need to add one custom field in that with the status information of records. that new field will get data from R/3 status table via extractor from CMOD.
now this Master data is having delta.
my confusion is if i add new field in it how the delta will react ? coz there are different status - eg. when user create the status - it will be "created" that time delta will pick up that record coz it has been changed. Now if user changes status to "closed" or "in transit" how delta will react ?
i meant is it doable to do like that ? any guidance will be appreciated.
Thanks in advance.Smith,
Your master data extractor will continue to give your existing fields- as for delta - it depends on how the delta is managed - you would have to find that oiut - is it on timestamp / date et etc... ?
CMOD will change only the extract structure and whenever this datasource is called - CMOD fills in the additional field - nothin about delta / init here...

I purchased an iPad mini on October 10th. I want to return it and get the new ipad mini retina when it comes out. I am currently still within the 14 day return/exchange window but how can I exchange it if the new ipad mini release date isn't until "later in November", which would be beyond the 14 days from my purchase date? If apple announces a new version of a product you just purchased but won't actually release it for more than 14 days, how can you possibly exchange the one you just bought? Is my only option to return the one I bought on the 10th (so return by 10/24) and then not have an iPad until the new one is available for purchase? Or would it make any sense to return the one I bought, get a new one, which would presumably have another 14 day return window, and then exchange THAT one for the new ipad mini w/ retina when it comes out (hopefully within that second 14 day window)?
Call the apple store you got it from and ask them. Sometimes in the past they've extended the 'no questions asked return' but only Apple can tell you for sure.

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.
But I am totally clueless how to search thru a vector based on 2 properties of the object... Would really appreciate some help. Like an example how to so so based on my program. Feelin so lost...This is all I have so far:
class AddReservation

public static void main (String[]args)throws IOException
String custName, comments;
int covers, date, startTime, endTime;

//User can only add one reservation at a time
do
//Create a new reservation
Reservation oneReservation=new Reservation();
System.out.println("Please enter customer's name:");
System.out.flush();
custName = stdin.readLine();
oneReservation.setcustName(custName);

Add new fields to additional data tab in customs declaration
Hello friends,
My requirement is to add Z fields in the additional data tab in transaction /SAPSLL/CL_CUS_02 of GTS. I would also like to know If its possible to create a new tab all together in /SAPSLL/CL_CUS_02 where in we can add fields from a custom table.
Thanks a lot in advance. Your help will be highly appreciated.
Regards,
KoustubhHi Koustubh,
As Dave pointed out, there is a BadI for extra tab on declaration Item and Header.
There is an example implementation already available in the System. I believe that 1 BadI will no be enough for what you need.
UI enhancement BadI uses standard CUHD and CUIT tables to store the extended data ( via table APPEND ), in order to save content to Z* table you will need a separate BaDI.
Also, If you intend to use this extra data in outbound message / declaration Idoc, extra BadI has to be used and also the basic IDoc type will need to be extended with your Z* segment. Thats probably 2-3 BadIs working in tandem.
Can you tell what is the purpose of the extra data / extra tab ?
Best Regards,
Branislav Petricek
