Can anybody give me a link or documentatiom for implementing BADI with an example not theoritical practical.
with regards,
chandu.

Practical examples for SAP BI

Hi BI-experts!
Can some one please recommend some practical examples/case studies to gain practical experience with SAP BI?
- Data modelling/procurement and Reporting
- Integrated Planing
- BW based Consolidation
Also other web sources, SAP books will be very appreciated.
I already went through the first example "From the Data Model to the BI Application in
the Web" and SAP courses SAP BW305 and 310.
Any helpful information will be very appreciated.
Thank you very much!
regards
Thom

Hi,
I suggest first you go through the what is BI? then where it is used, which scenario BI is usually required, for that go through this links,

Best practice question for implementing a custom component

I'm implementing a custom component which renders multiple <input type="text" .../> controls as part of it. The examples I've seen that do something similar use the ResponseWriter to generate the markup "by hand" like:
 writer.startElement("input", component);
 writer.writeAttribute("type", "text", null);
 writer.writeAttribute("id", "foo", null);
 writer.writeAttribute("name", "foo", null);
 writer.writeAttribute("value", "hello", null);
 writer.writeAttribute("size", "20", null);
 writer.endElement("input");
I don't know about anyone else, but I HATE having to write code that manufactures this stuff - seems to me that there are already classes that do this, so why not just use those? For example, the above could be replaced with:
 HtmlInputText textField = new HtmlInputText();
 textField.setId("foo");
 textField.setValue("hello");
 textField.setSize(20);
 // just to be safe, invoke both encodeBegin() and encodeEnd(),
 // though it seems like encodeEnd() actually does the work in this case,
 // but who knows if they might change it at some point
 textField.encodeBegin(context);
 textField.encodeEnd(context);
So my question is, why does everyone seem to favor the former over the latter? Why not leverage objects that already do the (encoding) work for you?

Got it!
You JSP should have this:
<h:panelGroup styleClass="jspPanel" id="jspPanel1"></h:panelGroup>
And your code page ValueChangeListener/ActionListner should have this:
 if (findComponent(getForm1(),"myOutputText") == null)
 FacesContext facesCtx = FacesContext.getCurrentInstance();
 System.out.println("Adding component");
 HtmlOutputText output =
 (HtmlOutputText) facesCtx.getApplication().createComponent(
 HtmlOutputText.COMPONENT_TYPE);
 output.setId("myOutputText");
 output.setValue("It works");
 getJspPanel1().getChildren().add(output);
 System.out.println("Done");
 DebugUtil.printTree(FacesContext.getCurrentInstance().getViewRoot(),System.out);
 else
 System.out.println("component already added");
I just have to figure out this IOException on the closed stream - probably has to do with [immidiate="true"].
Thanks.

Example for Implementing SQL Authenticator

Hi,
I am using JDev - 11.1.1.5.0 and WLS - 10.3
I have a standalone ADF Application which is assessed by users registered in Oracle Application System (11i/R12). I need to authenticate the users using entries in "fnd_user" and "fnd_responsibility" tables.
Since the password in "fnd_user" table is encrypted, I need a way to authenticate using username and password given in plain text in the login page. Taking these values I need to validate the user and the responsibility and then allow the user into the application.
Please let me know suitable example or document containing SQL Authentication with encrypted password i.e. using "fnd_user" table for authentication.
Thanks
Rathnam

Hi,
Maybe you are talking about hashing of passwords (but not about password encryption), because SHA-1 is not an encryption algorithm but a hashing one. If your table contains hash digests of passwords (e.g. MD5 or SHA-1 digests), you should set a statement similar to the one below into authenticator's parameter "SQL Get User Password":
<tt>SELECT '{SHA-1}' || UTL_RAW.CAST_TO_VARCHAR2( UTL_ENCODE.BASE64_ENCODE( password ))
FROM users_table
WHERE username = ?</tt>
This statement assumes that a SHA-1 digest of the password is stored in a DB column <tt>users_table.password</tt> of datatype RAW. If your algorithm is MD5, then replace <tt>{SHA-1}</tt> with <tt>{MD5}</tt> in the statement above. If your column is not of datatype RAW, then modify the SELECT statment accordingly.

Doubts in XI basics..help me with some practical examples

hi friends,
I am new to SAP XI have some basic doubts. Answer my questions with some practical examples.
1. what is meant by "Business System" and what is difference between client,customer,Business partner,3rd party
2.If a small company already using some systems like Oracle or peopleSoft,if it wants to use SAP products then what steps it has to follow.
3. SAP system means a SERVER?
4.SAPWebAs means a server software?
5.R/3 system comes under SAP system?
6.XI is also one of the SAP module..how it relates to other modules.
7.In one organization which is using SAP modules,each module will be load in separate servers?
8.PO(purchase order) means just looks like one HTML file..customer will fill the form and give it.like this,Combination of many files like this is one SAP module.Is it right assumption..?if so,then what is speciality SAP?
I have an theoretical knowledge about IR and ID and SLD.what are general business transactions happens in any business ?(like who will send cotation,PO) give some practical example for what actually happens in business?..who will do what?and what XI will do?

Hi Murali,
 1.Business System
Business systems are logical systems that function as senders or receivers within the SAP Exchange Infrastructure(XI).
Before starting with any XI interface,the Business systems involved has to be configured in SLD(The SLD acts as the central information provider for all installed system components in your system landscape.)
business system and technical system in XI
2.Third Party
http://help.sap.com/saphelp_nw04/helpdata/en/09/6beb170d324216aaf1fe2feb8ed374/frameset.htm
eg.For the SAP system a Bank would be a third-party which would be involved in interfaces involving exchange of data(Bill Payment by customer).
3.XI(Exchange Infrastructure)
It enables you to connect systems from different vendors (non-SAP and SAP) in different versions and implemented in different programming languages (Java, ABAP, and so on) to each other.
Eg.If an interface involves Purchase Order sent from SAP system to the vendor(Non-SAP system)then,the vendor might expect a file.But the Data is in the IDOC(intermediate document) form with the SAP system.Here XI does the work of mapping the IDOC fields and the File fields and sends it to the vendor in the form of a file.
In short,always the scene is Sender-XI-Receiver.
The Sender and the Receiver depends upon the Business you are dealing with.
4.Business Partner
A person, organization, group of persons, or group of organizations in which a company has a business interest.
This can also be a person, organization or group within this company.
Examples:
Mrs. Lisa Miller
Maier Electricals Inc.
Purchasing department of Maier Electricals Inc.
5.Client

Implementing BADI ALM_ME_001_ORDER

Hi All,
MAM30 SR1
MI25 SP15
I followed the guide for implementing BADI ALM_ME_001_ORDER to get more fields for the ORDER_OPERATION details.
In the MI server, merep_mon says my fields and values are there and enhancement flags, and so as in the device - if I look in start.jsp.
But they are nowhere to be found on the screen. What did I miss?
Here's what I did:
1) added fields in CI_ALM_ME_ORDER_OPERATION structure
2) implemented BADI method MAM30_GETDETAIL
METHOD if_ex_alm_me_001_order~mam30_getdetail .
DATA: l_oper TYPE mam_30_order_operation,
 lce_oper TYPE alm_me_custom_order_operation.
LOOP AT order_operation INTO l_oper.
 clear lce_oper.
 lce_oper-zusr00 = l_oper-usr00.
 lce_oper-zusr01 = l_oper-usr01.
 lce_oper-zusr02 = l_oper-usr02.
 lce_oper-zusr03 = l_oper-usr03.
 lce_oper-key_activity = l_oper-activity.
 lce_oper-key_sub_activity = l_oper-sub_activity.
 APPEND lce_oper TO ce_order_operation.
 l_oper-enhancement_flag = 'X'.
 MODIFY order_operation
 FROM l_oper TRANSPORTING enhancement_flag.
ENDLOOP.
ENDMETHOD.
3) implemented BADI method MAM30_GETLIST
METHOD if_ex_alm_me_001_order~mam30_getlist .
DATA l_order_list TYPE mam_30_order_header.
LOOP AT order_list INTO l_order_list.
 l_order_list-enhancement_flag = 'X'.
 MODIFY order_list
 FROM l_order_list TRANSPORTING enhancement_flag.
ENDLOOP.
ENDMETHOD.


Hi Kuya!
Did you activate your BADI implementation in SE19?
Thank You

Best Practices guide for BW in SRM?

Dear Friends,
Is there a SAP Best Practices guide for implementing SRM in BW? If so please help with links and documenation. My email id is <removed by moderator>....
Thanks
Raj

Hello ,
I assume you are looking BW integration for SRM.
In the related business scenario config guides at the end they have given necessary BW integration with SRM.
I will send you the guides.
Mostly you should refer the 'spend analysis' guides as it talks mostly on integartion and reporiting in SRM through BW.

BADI for practice: example plz

hi
i need several concrete example of BADI:
1 to understand how filter BADI work
2 to understand how multiple purpose BADI work
3 Implementation of already enhance BADI
4 defining new BADI and implementing it
I already read lots of docs on BADI but to really understand how it work i need to actually do an example

Hi
Business Add-Ins
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
As with customer exits (SMOD/CMOD [Page 40]), two different views are available:
In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.
In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.
In contrast to customer exits, Business Add-Ins no longer assume a two-system infrastructure (SAP and customers), but instead allow for multiple levels of software development (by SAP, partners, and customers, and as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.
SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time.
In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example). All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard.
A single Business Add-In contains all of the interfaces necessary to implement a specific task. In Release 4.6A, program and menu enhancements can be made with Business Add-Ins. The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects
DEFINING THE BADI
1) execute Tcode SE18.
2) Specify a definition Name : ZBADI_SPFLI
3) Press create
4) Choose the attribute tab. Specify short desc for badi.. and specify the type :
multiple use.

8) place the cursor on the method name desc its parameters to define the interface.
Parameter type refe field desc
I_carrid import spfli-carrid some
I_connid import spefi-connid some
9) save , check and activateadapter class proposed by system is
ZCL_IM_IM_LINESEL is genereated.
IMPLEMENTATION OF BADI DEFINITION
1) EXECUTE tcode se18.choose menuitem create from the implementation menubar.
2) Specify aname for implementation ZIM_LINESEL
3) Specify short desc.
4) Choose interface tab. System proposes a name fo the implementation class.

Catalogue of SQL and PL/SQL bad practices: Call for participation

I started compiling a list of Oracle SQL and PL/SQL bad practices, with the intention of producing a comprehensive catalogue of common and recurring programming mistakes, that can be used as a check-list for code reviews or given to junior developers. I have identified about 30 bad practices so far. For each bad practice, I provided a list of symptoms in the code, an explanation why it causes problems and a list of preferred solutions.
My goal with this list is primarily to start a discussion about similar recurring issues that other people have noticed. That discussion should lead to a more complete list which the community will then be able to use, hopefully, to learn something from the mistakes of others and to produce better code.
I would really appreciate your feedback - if you are interested in discussing these practices we can either do it in this forum, or start a separate mailing list.
You can download the first version of the catalogue in PDF form from http://gojko.net/effective-oracle

exception handler (already covered), the philosophy
behind not using stored procedures, and having beenHi riedelme,
I'm not advocating not using stored procedures, but I am advocating not using exclusively stored procedures. I've seen that approach often, typically with people coming from SQL server or Oracle forms backgrounds, I never could understand the reasons behind it. Even for a simple select or update, they would write a stored proc that wraps the call and then require the client to execute a stored proc.
I think that views are much better for getting the data out of the database in general, and forcing people to use stored procedures with ref output cursors makes little sense. If the only possible interface is a stored proc, then one proc must be created for every required combination of data and every required filtering or grouping method, so there is much much more code in the database, and more code means harder maintenance.
If client apps can get data out using views, then they can join them with other views, filter or group the data as they require, which means that there is a lot less code in the database to maintain.
My other problem with stored-proc only approach is when people wrap simple insert/update/delete commands into a stored proc. Again, I'm not advocating using complex instead-of triggers to implement workflows and forcing people to use views, but I simply don't see any benefit of implementing a stored proc to do a simple update. I see a bad side of it because a stored proc needs to be implemented for every combination of columns that a client may need to update and every criteria that can be used for that. If a client is allowed to update a view, there is much less code in the database.
Views are, in my experience, also a lot easier to maintain and optimise without downtime because they can be revalidated without causing any problems to currently connected clients, where revalidated stored procedure or package will throw an exception the first time a connected client that had called it before calls it again.
If I'm missing something, please tell me. I'd really love to understand why someone would build a client API exclusively from stored procedures.
So far, I've been given explanations that it is for security purposes, or for performance. I don't know of any security restriction that can be implemented on a stored procedure or package that cannot be implemented with a view, and if bound variables and statement caching is used, sql statements don't suffer from sql injection and support pre-compilation.
Again, i'm not advocating throwing stored procs completely out, i'm against using them exclusively and throwing out any chance of SQL access.

How may implementations can we have for a BaDI?

How may implementations can we have for a BaDI?

if BADI check Multi-USE , then u can
Multiple-Use Business Add-Ins
You can differentiate between single-use and multiple use Business Add-Ins. The distinction is based on the procedure or event character of an enhancement. In the first case, the program waits for the enhancement to return something, usually a return code. A typical example could be a benefit calculation in HR. Depending on the implementation, alternative calculations can be executed. With multiple use add-ins, an event that may be of interest to other components is processed in program flow. Any number of components could use this event as a hook to hang their own additional actions on to.
In addition to importing parameters, you can also use changing parameters for multiple-use Business Add-Ins. There is no sequence control for multiple-use implementations of BadIs. Therefore, using changing parameters can cause problems. There is no guarantee that implementations will not overwrite the results of previous implementations. Sequence control is technically impossible, since at the time of the definition the interface does not know which implementations there will be and which parameters will be changed by implementations. It is not possible to have a decision as to which implementation should be executed before which other (future) implementation.
Example:
In a particular application, you want to be able to continue processing indexes after another component has saved data (in other words, the system should allow you to use an add-in after saving). Since this point in time can be useful for different purposes, you can create an enhancement here that can be used by multiple subscribers.
To create a multiple-use Business Add-In, proceed as follows:
       1.      Define an add-in and select the Multiple Use checkbox from the Administration tab.
       2.      Define an interface with the method OBJECT_SAVED'and the importing parameter OBJECTNAME.
Calling your enhancement in the application program:
program event.
data exit_obj type ref to if_ex_event.
call method cl_exithandler =>get_instance
     changing instance = exit.
form save_object using obj_name type c.
update
call method exit_obj->object_saved
     exporting objectname = obj_name.
endform.
For the caller it is irrelevant whether (and how many) subscribers use the event as a starting point for further actions. The active implementations are called in the adapter method.

Best practice for implementing Manufacturing Cost Planning ( MCP)

is there any best practice for implementing Manufacturing Cost Planning ( MCP) using BI-IP?

Hi:
Both options are viable. If you reverse posting in FB50 then FI GL account postings will also be reversed and along with cost center postings. Hence here advantage is that cost center reversal will be with referenced to the original document with which wrong posting were made. Disadvantage here is that you will to post the entry again in FB50 . In KB11N you will simply transfer cost center amount from wrong to new one that should be in place of it but here you will have no reference . I personally think reversing posting through FB50 is viable options , reverse postings can be seen in KSB1 as well against that cost center.

How to know if implementation with a filter value exist for a BAdI in code?

Hi all,
Scenario:
I created a BAdI. There will be a button on the UI to call its implementation(s); while if there is no implementation with specified filter value, this button needs to be hidden. Thus I need to know if the implementation exist before calling it.
Question:
In the ABAP code, how to get whether implementation with specified filter value exists for a BAdI?
If it's possible, please help provide code.
Thanks and regards,
Said

Problem solved:
data: r_badi type ref to YOUR_BADI,
          badi_impl_num type i.
get badi r_badi
    filters
      flt_name = fit_val.
badi_impl_num = cl_badi_query=>number_of_implementations( badi = r_badi ).
if badi_impl_num > 0.
    "there are badi implementation(s)
endif.

Unable to create the implementation for BBP_PD_DOWNLOAD badi

Hi ,
Iam trying to create a new implementation for this BADI BBP_PD_DOWNLOAD as zbbp_pd_download but when iam trying to activate it .iam getting a message that already active implementation is there and i cannot create a new implementation unless i deactivate the other one.since it is a standard one i cannot deactivate it .
Has any one used this earlier . any inputs on this wil be of great help .
Thanks in advance

Hi
You can create any number of Customer Implementations, provided only one is active at a time.
Here are the steps ->
Either Using SE18 / SE19 Transaction, or
After you call the IMG activity, the system displays a dialog box where you enter a name for the implementation.
If implementations of this Business Add-In have already been created, the system displays them in a dialog box. You then choose one of them by choosing Create, and continue as follows:
1. In the dialog box, enter a name for the implementation of the Add-In and choose Create. (Say ZBADI)
The system displays the initial screen for creating Business Add-In implementations.
2. On this screen, enter a short description for you implementation in the Implementation Short Text field.
3. If you choose the Interface tab, you will notice that the system has filled in the Name of the Implementing Class field automatically, by assigning a class name based on the name of your implementation.
4. Save your entries and assign the Add-In to a package.
5. To edit a method, double-click its name.
6. Enter your implementation code between the method <Interface Name>~<Name of Method>. and endmethod. statements.
7. Save and activate your code. Navigate back to the Change Implementation screen.
Note: You can also create an implementation for an Add-In and not activate it until later. If you want to do this, do not carry out the following step:
8. Choose Activate.
When the application program is executed, the system carries out the code in the method you wrote.
