ABAP interface in real time

Dear all,
Hereafter is my scenario;
My customer after sales system works on AS400. Assuming that I would manage spare parts (required for after sales) inventory, including goods entry, goods issue as well as the company financial accounting in SAP, I have to interface the two system.
From SAP to AS400: (flow1) Master files + (flow2) goods entry
From AS400 to SAP: (flow3) AR postings, (flow4) goods consumption
Then my two systems will be in line in terms of referential data (flow1), stock movement (flow2 + flow4), invoicing (flow3).
1) My question is to know what would be the best way to flow2 knowing that stock movement following a goods entry (done in SAP) should be visible in real time from AS400?
2) Regarding other flows, no need for real time. So I guess flat file should be ok. However, would master data for instance sent from SAP to AS400 require a mapping table in order to be properly integrated in AS400?
Regards.

Real Time doesn't mean always fast. It depends on your application requirements.
Anyway, don't think too much about Real Time in Windows. If it's possible, try to do all "time critical" operations in Matlab and after that pull data with LV.

How do I generate a compiled app with a user interface running real-time?

Hi everyone,
I've developed a simple application that uses a PXI chassis to run. It toggles some discretes and does some simple things, but it doesn't really have any "real-time" requirements. We're just using the PXI chassis because we have it and we need the discrete I/O.
My question is this - how can I convert this application to a compiled real-time app and yet maintain the front panel on the local PC. LabView appears to simply do this for me. I am connected to the real-time target via ethernet. When I compiled the program, it puts it in the target's startup directory, but how do I run the front panel from the local PC?
Thanks,
Jason

Hi Jason,
Below are some links that should get you started with deploying an application onto your real-time target and then controlling it from a PC that does not have the LabVIEW Development environment:

Hi
Logical database
A logical database is a special ABAP/4 program which combines the contents of certain database tables. Using logical databases facilitates the process of reading database tables.
HR Logical Database is PNP
Main Functions of the logical database PNP:
Standard Selection screen
Data Retrieval
Authorization check
To use logical database PNP in your program, specify in your program attributes.
Standard Selection Screen
Date selection
Date selection delimits the time period for which data is evaluated. GET PERNR retrieves all records of the relevant infotypes from the database. When you enter a date selection period, the PROVIDE loop retrieves the infotype records whose validity period overlaps with at least one day of this period.
Person selection
Person selection is the 'true' selection of choosing a group of employees for whom the report is to run.
Sorting Data
· The standard sort sequence lists personnel numbers in ascending order.
· SORT function allows you to sort the report data otherwise. All the sorting fields are from infotype 0001.
Report Class
· You can suppress input fields which are not used on the selection screen by assigning a report class to your program.
· If SAP standard delivered report classes do not satisfy your requirements, you can create your own report class through the IMG.
Data Retrieval from LDB
1. Create data structures for infotypes.
    INFOTYPES: 0001, "ORG ASSIGNMENT
                        0002, "PERSONAL DATA
                        0008. "BASIC PAY
2. Fill data structures with the infotype records.
    Start-of-selection.
         GET PERNR.
    End-0f-selection.
    Read Master Data
Infotype structures (after GET PERNR) are internal tables loaded with data.
The infotype records (selected within the period) are processed sequentially by the PROVIDE - ENDPROVIDE loop.
          GET PERNR.
             PROVIDE * FROM Pnnnn BETWEEN PN/BEGDA AND PN/ENDDA
                    If Pnnnn-XXXX = ' '. write:/ Pnnnn-XXXX. endif.
             ENDPROVIDE.
Period-Related Data
All infotype records are time stamped.
IT0006 (Address infotype)
01/01/1990   12/31/9999 present
          Which record to be read depends on the date selection period specified on the
          selection screen. PN/BEGDA PN/ENDDA.
Current Data
IT0006 Address - 01/01/1990 12/31/9999   present
RP-PROVIDE-FROM-LAST retrieves the record which is valid in the data selection period.
For example, pn/begda = '19990931'    pn/endda = '99991231'
IT0006 subtype 1 is resident address
RP-PROVIDE-FROM-LAST P0006 1 PN/BEGDA PN/ENDDA.
Process Infotypes
RMAC Modules - RMAC module as referred to Macro, is a special construct of ABAP/4 codes. Normally, the program code of these modules is stored in table 'TRMAC'. The table key combines the program code under a given name. It can also be defined in programs.The RMAC defined in the TRMAC can be used in all Reports. When an RMAC is changed, the report has to be regenerated manually to reflect the change.
Reading Infotypes - by using RMAC (macro) RP-READ-INFOTYPE
          REPORT ZHR00001.
          INFOTYPE: 0002.
          PARAMETERS: PERNR LIKE P0002-PERNR.
          RP-READ-INFOTYPE PERNR 0002 P0002 .
          PROVIDE * FROM P0002
              if ... then ...endif.
          ENDPROVIDE.
Changing Infotypes - by using RMAC (macro) RP-READ-INFOTYPE.
· Three steps are involved in changing infotypes:
1. Select the infotype records to be changed;
2. Make the required changes and store the records in an alternative table;
3. Save this table to the database;
The RP-UPDATE macro updates the database. The parameters of this macro are the OLD internal table containing the unchanged records and the NEW internal table containing the changed records. You cannot create or delete data. Only modification is possible.
INFOTYPES: Pnnnn NAME OLD,
Pnnnn NAME NEW.
GET PERNR.
    PROVIDE * FROM OLD
           WHERE .... = ... "Change old record
           *Save old record in alternate table
           NEW = OLD.
    ENDPROVIDE.
    RP-UPDATE OLD NEW. "Update changed record
Infotype with repeat structures
· How to identify repeat structures.
a. On infotype entry screen, data is entered in table form.
    IT0005, IT0008, IT0041, etc.
b. In the infotype structure, fields are grouped by the same name followed by sequence number.
    P0005-UARnn P0005-UANnn P0005-UBEnn
    P0005-UENnn P0005-UABnn
Repeat Structures
· Data is entered on the infotype screen in table format but stored on the database in a linear
structure.
· Each row of the table is stored in the same record on the database.
· When evaluating a repeat structure, you must define the starting point, the increment and the
work area which contains the complete field group definition.
Repeat Structures Evaluation (I)
· To evaluate the repeat structures
   a. Define work area.
       The work area is a field string. Its structure is identical to that of the field group.
   b. Use a DO LOOP to divide the repeat structure into segments and make it available for
       processing in the work area, one field group (block) at a time.
Repeat Structures Evaluation(II)
Define work area
DATA: BEGIN OF VACATION,
              UAR LIKE P0005-UAR01, "Leave type

      ENDDO.
Processing 'Time Data'.
· Dependence of time data on validity period
· Importing time data
· Processing time data using internal tables
Time Data and Validity Period
· Time data always applies to a specific validity period.
· The validity periods of different types of time data are not always the same as the date selection period specified in the selection screen.
Date selection period |----
|
Leave |----
|
· PROVIDE in this case is therefore not used for time infotypes.
Importing Time Data
· GET PERNR reads all time infotypes from the lowest to highest system data, not only those within the date selection period.
· To prevent memory overload, add MODE N to the infotype declaration. This prevents the logical database from importing all data into infotype tables at GET PERNR.
· Use macro RP-READ-ALL-TIME-ITY to fill infotype table.
INFOTYPES: 2001 MODE N.
GET PERNR.
    RP-READ-ALL-TIME-ITY PN/BEGDA PN/ENDDA.
    LOOP AT P0021.
         If P0021-XYZ = ' '. A=B. Endif.
    ENDLOOP.
Processing Time Data
· Once data is imported into infotype tables, you can use an internal table to process the interested data.
DATA: BEGIN OF ITAB OCCURS 0,
              BUKRS LIKE P0001-BUKRS, "COMPANY

Database Tables in HR
· Personnel Administration (PA) - master and time data infotype tables (transparent tables).
   PAnnnn: e.g. PA0001 for infotype 0001
· Personnel Development (PD) - Org Unit, Job, Position, etc. (transparent tables).
   HRPnnnn: e.g. HRP1000 for infotype 1000
· Time/Travel expense/Payroll/Applicant Tracking data/HR work areas/Documents (cluster
   PCLn: e.g. PCL2 for time/payroll results.
Cluster Table
· Cluster tables combine the data from several tables with identical (or almost identical) keys
into one physical record on the database.
. Data is written to a database in compressed form.
· Retrieval of data is very fast if the primary key is known.
· Cluster tables are defined in the data dictionary as transparent tables.
· External programs can NOT interpret the data in a cluster table.
· Special language elements EXPORT TO DATABASE, IMPORT TO DATABASE and DELETE
FROM DATABASE are used to process data in the cluster tables.
PCL1 - Database for HR work area;
PCL2 - Accounting Results (time, travel expense and payroll);
PCL3 - Applicant tracking data;
PCL4 - Documents, Payroll year-end Tax data
Database Tables PCLn
· PCLn database tables are divided into subareas known as data clusters.
· Data Clusters are identified by a two-character code. e.g RU for US payroll result, B2 for
time evaluation result...
· Each HR subarea has its own cluster.
· Each subarea has its own key.
Database Table PCL1
· The database table PCL1 contains the following data areas:
B1 time events/PDC
G1 group incentive wages
L1 individual incentive wages
PC personal calendar
TE travel expenses/payroll results
TS travel expenses/master data
TX infotype texts
ZI PDC interface -> cost account
Database Table PCL2
· The database table PCL2 contains the following data areas:
B2 time accounting results
CD cluster directory of the CD manager
PS generated schemas
PT texts for generated schemas
RX payroll accounting results/international
Rn payroll accounting results/country-specific ( n = HR country indicator )
ZL personal work schedule
Database Table PCL3
· The database table PCL3 contains the following data areas:
AP action log / time schedule
TY texts for applicant data infotypes
Data Management of PCLn
· The ABAP commands IMPORT and EXPORT are used for management of read/write to
database tables PCLn.
· A unique key has to be used when reading data from or writing data to the PCLn.
Field Name KEY Length Text
MANDT X 3 Client
RELID X 2 Relation ID (RU,B2..)
SRTFD X 40 Work Area Key
SRTF2 X 4 Sort key for dup. key
Cluster Definition
· The data definition of a work area for PCLn is specified in separate programs which comply
   with fixed naming conventions.
· They are defined as INCLUDE programs (RPCnxxy0). The following naming convention applies:
   n = 1 or 2 (PCL1 or PCL2)
   xx = Relation ID (e.g. RX)
   y = 0 for international clusters or country indicator (T500L) for different country cluster
Exporting Data (I)
· The EXPORT command causes one or more 'xy' KEY data objects to be written to cluster xy.
· The cluster definition is integrated with the INCLUDE statement.
REPORT ZHREXPRT.
TABLES: PCLn.
INCLUDE: RPCnxxy0. "Cluster definition
Fill cluster KEY
xy-key-field = .
Fill data object
Export record
EXPORT TABLE1 TO DATABASE PCLn(xy) ID xy-KEY.
   IF SY-SUBRC EQ 0.
       WRITE: / 'Update successful'.
   ENDIF.
Exporting Data (II)
. Export data using macro RP-EXP-Cn-xy.
· When data records are exported using macro, they are not written to the database but to a
main memory buffer.
· To save data, use the PREPARE_UPDATE routine with the USING parameter 'V'.
REPORT ZHREXPRT.
*Buffer definition
INCLUDE RPPPXD00. INCLUDE RPPPXM00. "Buffer management

INCLUDE RPPPXD10.
DATA: END OF COMMON PART 'BUFFER'.
RP-EXP-Cn-xy.
IF SY-SUBRC EQ 0.
    PERFORM PREPARE_UPDATE USING 'V'..
ENDIF.
Importing Data (I)
· The IMPORT command causes data objects with the specified key values to be read from
   PCLn.
· If the import is successful, SY-SUBRC is 0; if not, it is 4.
REPORT RPIMPORT.
TABLES: PCLn.
INCLUDE RPCnxxy0. "Cluster definition
Fill cluster Key
Import record
IMPORT TABLE1 FROM DATABASE PCLn(xy) ID xy-KEY.
   IF SY-SUBRC EQ 0.
Display data object
   ENDIF.
Importing data (II)
· Import data using macro RP-IMP-Cn-xy.
· Check return code SY-SUBRC. If 0, it is successful. If 4, error.
· Need include buffer management routines RPPPXM00
REPORT RPIMPORT.
*Buffer definition

DATA: BEGIN OF COMMON PART 'BUFFER'.
INCLUDE RPPPXD10.
DATA: END OF COMMON PART 'BUFFER'.
*import data to buffer
RP-IMP-Cn-xy.
*Buffer management routines
INCLUDE RPPPXM00.
Cluster Authorization
· Simple EXPORT/IMPORT statement does not check for cluster authorization.
· Use EXPORT/IMPORT via buffer, the buffer management routines check for cluster
authorization.
Payroll Results (I)
· Payroll results are stored in cluster Rn of PCL2 as field string and internal tables.
n - country identifier.
· Standard reports read the results from cluster Rn. Report RPCLSTRn lists all payroll results;
report RPCEDTn0 lists the results on a payroll form.
Payroll Results (II)
· The cluster definition of payroll results is stored in two INLCUDE reports:
include: rpc2rx09. "Definition Cluster Ru (I)
include: rpc2ruu0. "Definition Cluster Ru (II)
The first INCLUDE defines the country-independent part; The second INCLUDE defines the country-specific part (US).
· The cluster key is stored in the field string RX-KEY.
Payroll Results (III)
· All the field string and internal tables stored in PCL2 are defined in the ABAP/4 dictionary. This
allows you to use the same structures in different definitions and nonetheless maintain data
consistency.
· The structures for cluster definition comply with the name convention PCnnn. Unfortunately,
   'nnn' can be any set of alphanumeric characters.
*Key definition
DATA: BEGIN OF RX-KEY.
     INCLUDE STRUCTURE PC200.

*Payroll directory
DATA: BEGIN OF RGDIR OCCURS 100.
     INCLUDE STRUCTURE PC261.

Payroll Cluster Directory
· To read payroll results, you need two keys: pernr and seqno
. You can get SEQNO by importing the cluster directory (CD) first.
REPORT ZHRIMPRT.
TABLES: PERNR, PCL1, PCL2.
INLCUDE: rpc2cd09. "definition cluster CD

Function Module (I)
CD_EVALUATION_PERIODS
· After importing the payroll directory, which record to read is up to the programmer.
· Each payroll result has a status.
'P' - previous result
'A' - current (actual) result
'O' - old result
· Function module CD_EVALUATION_PERIODS will restore the payroll result status for a period
   when that payroll is initially run. It also will select all the relevant periods to be evaluated.

Authorization Check
   Authorization for Persons
· In the authorization check for persons, the system determines whether the user has the
   authorizations required for the organizational features of the employees selected with
   GET PERNR.
· Employees for which the user has no authorization are skipped and appear in a list at the end
   of the report.
· Authorization object: 'HR: Master data'
Authorization for Data
· In the authorization check for data, the system determines whether the user is authorized to
read the infotypes specified in the report.
· If the authorization for a particular infotype is missing, the evaluation is terminated and an error
message is displayed.
Deactivating the Authorization Check
· In certain reports, it may be useful to deactivate the authorization check in order to improve
performance. (e.g. when running payroll)
· You can store this information in the object 'HR: Reporting'.
these are the main areas they ask q?

How much interfaces can be driven in "real-time" with a VI in LABVIEW 6i

In my application I need to merged data from different devices hanging to my computer via different interface types. Each data set in to be specifically formatted in a file. Each data set comes a a rate of ~ 10 Hz.
As acquisition devices I do have
- 4 digitizers connected to the PCI bus and their labview driver are already given by the constructor
- an instrument from which data to be imported via a GPIB interface
- an instrument from which data are imported via a serial port
- and probably in the future, 2 devices mounted on two USB port
I wish to developp a LABVIEW 6i code which permit me to make the request to all instrument, to import the data and to merged them as quick as possible so
that I can store data set coming every 0,1 s. All data from all instruments must be recorded for the same event at the same time (in a triggered manner) before it performs the acquistions for the next event
I would like to know what is the best way to each my goal.
- Is it possible to control all this with one VI (containing lot of VIs) ?
- Should I execute a VI for each interface and run them at the same time and save all data set with a time stamps in a file and then, off-line, process all the files and merge my information.
In a general manner, are there any rules which indicate the maximum number of interface (according to their nature) which can be properly controled on a given platform from one computer.
Thanks you very much for any answers

Its been a couple of days with no reply....
Look at the occurence functions.
You can have one loop send occurences at teh rate you need.
Put each of the other functions in seperate loops that wait for the occurence on each interation.
Provided each of your loops runs fast enough this approach should serve you up till you run into the indeterminism of Windows. If the the indeterminism will be an issue, you may have to go with LV Real-Time.

FieldPoint real-time controller or Ethernet interface

Good Afternoon,
The first feature listed on the FP-2000 product page is:
Stand-alone embedded real-time controller or Ethernet interface for PC-based distributed I/O.
Has anybody successfully implented a FP-2000 as an Ethernet interface for PC-based distributed I/O? In other words, have the FP-2000 act like a FP-1600?
There are some discussion forum threads that dance around the subject but I have not found one that really answers it.
Thanks,
Ed
Solved!
Go to Solution.

Hi edlad,
After playing around with a FP-2010 for a while, I do believe that you need to install LabVIEW Real-Time on the controller in order for it to work, even if you are technically not using it because you are not running a VI/executable on the controller. As far as your issue with installing LabVIEW 8.5.1 on a FP-2000, that is troubling because there should not be an issue doing this at all. In fact, I have personally been able to install LabVIEW 8.5.1 on many FP-2000s. For that issue, I would suggest reformatting the FP-2000 from MAX and try again.
ThinkG: Regarding your question about using a cFP-2220 to communicate with Lookout, I am not sure because Lookout support is handled by our Shanghai branch via email only. However, I do know that you can use that second ethernet port to communicate with another FieldPoint network module (cFP-180x) using the FieldPoint drivers. Here are a couple good KnowledgeBase articles regarding that configuration. I hope they are helpful.

Real time in webdynpro ABAP?

Hello Frends,
I am new to webdynpro fr ABAP. I have been working from the past 2 yrs on ABAP R/3. Recently I have been trained on OOPS, BSP and Webdynpro fr ABAP fr a CRM project. Before I get in to the project, i just wanted to know, how and what exactly I need to do in real time. How the requirement comes for a webdynpro and how different is it from R/3. If I can get the information more on what will be done in real time, would be appreciated.
Thanks,
Regards.

Hi Rao,
Wrong place to be looking for Interview questions my friend try google instead , if you are looking for some excercises than try this link Web Dynpro ABAP exercises from TechEd 2007 for ABAP Trial Version
Happy Learning,

Need ABAP real time questions

hello ABAP gurus,
i am a fresh ABAper, technically very sound, but not getting job as a fresh ABAPer. So i am showing +2 years fake exp.
I usually clear the ABAP tech round, but always being rejected because of the lack of real time ABAP questions those r usually put/asked by the interviewers to trap the fake candidates.
If anybody having such question and answers, plz open to the SAP community.
it will be really the most rewardable help to all ABAP freshers.

You'd think so, but in some countries it can be very messy and costly to get rid of someone even if they did get the job dishonestly or under false pretences.
It also means that the person who made the decision to hire them has to admit he was wrong ...
I once saw a guy who'd been on two projects with a consulting firm - kicked off both within a few weeks and spenmt a year on the bench - get hired as develpment manager. Now there were three guys from his ex-firm already on site and the dork who hired him didn't even think to informally ask them. When the penny dropped they tried demoting him and he threatined to sue.
You think Dilbert is fiction?

FEDEX / UPS real-time interface

Hello All,
did any one worked with real-time interface to FEDEX/UPS using XI ?
any input greatly appreciated?
Thanks

My company specializes on multi carrier shipping solutions. We have an interfacing white paper if you are interested.
Before using the interfaces described above you need to consider the following attributes about your shipping. The thing is the carriers systems have both legal licensing restrictions, performance issues and compliance issues that you need to consider.
- Do you need to rate compare between carriers. ( This is a legal issue with the on-line services ).
- What modes of transport are you going to ship. Is it all parcel or are there some freight ( not all the services are available through the API's ).
- What volume? ( this is key.. the on-line carrier API's are designed for a couple of hundred parcels per day max ).
- How often does you company change carriers? ( each carrier is constantly changing and there is no interface standard in the industry ).
If you want to chat more please feel free to call me on 508.787.1842. I would also be happy to e-mail you interfacing white papers if thats of interest. [email protected]
Good Luck

Implementing Real Time, Outbound Interfaces

Hi All,
I have never worked on Interfaces before.
I need help in Real time, Outbound Interfaces.
How do we implement Real Time and Outbound Interfaces.
Any pointers or suggestions would really be helpful.
Thanks,
Saher

Unless you just wanted to play with sockets for the experience in which case you can do as you like. If you want get better with Java networking then IMO you must get ejp's book. [http://www.amazon.com/Fundamental-Networking-Java-Esmond-Pitt/dp/1846280303]
It's more of a fix before we release it to the poor souls that will be using our software, oh how the public are blind...

How do you interface a Renishaw laser real-time with NI DAQ?

I understand that it is possible to acquire "real time" feedback from a Rensishaw Laser while measuring linear position, with the following modifiers applied.
*The standard output is a digitized value to a proprietary (Renishaw) data acquisition (DAQ) card.
*Renishaw lasers have a quadrature output facility on the back of the laser head. This permits capture of the �raw� interferometry signal. This raw signal is not compensated for environmental factors such as temperature, air pressure, humidity, etc.
*The standard system integrates signals from an environmental unit for air temperature, pressure, and humidity, as well as signals from up to three material probes. Acquisition and pro
cessing of these or equivalent signals would have to be considered to provide data for environmental compensation calculations (Edlen equation). This is mandatory in order to obtain accurate distance and velocity readings.
*The quadrature output can communicate with other cards. (NI DAQ?)
Specifics with regard to Labview software and required DAQ to read real time Laser output would be very much appreciated.

You can use a counter available on the E-series MIO DAQ boards or the 660x counter boards. You can measure the position, frequency, and period of the output from a quadrature encoder. Examples on how to measure signals from a quadrature encoder for LabVIEW can be found on the web at ww.ni.com/support under the technical resource section search under the example programs section.
You may also want to contact Renishaw to see if they have drivers available for LabVIEW and their DAQ equipment.

BAdI........How are they used in the real time scenario.

Im a rookie in ABAP development and i was wondering that how we use the BAdI enhancement technique in the real time scenarios. Like do we get create them or we have few already built BAdI's which we work on? Can any body please explain how this works.

Hi Ramana,
Business add-ins are enhancements to the standard version of the system.
Business Add-In is a new SAP enhancement technique based on ABAP Objects.
They can be inserted into the SAP system based on specific user requirements.
Each Business Add-In has:
at least one Business Add-In definition
a Business Add-In interface
a Business Add-In class that implements the interface
In order to enhance a program, a Business Add-In must first be defined
Subsequently two classes are automatically generated:
An interface with IF_EX_ inserted between the first and second characters of the BADI name.
An adapter class with CL_EX_ inserted between the first and second characters of the BADI name.
The Application developer creates an interface for this Add-In.
There are multiple ways of searching for BADI.
Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
Finding BADI Using SQL Trace (TCODE-ST05).
Finding BADI Using Repository Information System (TCODE- SE84).
1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for CL_EXITHANDLER=>GET_INSTANCE.
Make sure the radio button In main program is checked. A list of all the programs with call to the BADIs will be listed.
The export parameter EXIT_NAME for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter INSTANCE will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
2. Start transaction ST05 (Performance Analysis).
Set flag field "Buffer trace"
Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)
Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.
Push the button "Deactivate Trace".
Push the button "Display Trace".
The popup screen "Set Restrictions for Displaying Trace" appears.
Now, filter the trace on Objects:
V_EXT_IMP
V_EXT_ACT
Push button "Multiple selections" button behind field Objects
Fill: V_EXT_IMP and V_EXT_ACT
All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.
So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA
3. Go to Maintain Transaction (TCODE- SE93).
Enter the Transaction VD02 for which you want to find BADI.
Click on the Display push buttons.
Get the Package Name. (Package VS in this case)
Go to TCode: SE84->Enhancements->Business Add-inns->Definition
Enter the Package Name and Execute.
Here you get a list of all the Enhancement BADIs for the given package MB.

Real time synchronisation of sap hr employee data with LDAP

Hi friends,
I wanted to synchronize sap hr employee data with ldap. I have written a abap program for the same which is using ldap connector interface for creation/modification/deletion of employees. I am planning to put this as a scheduled job.
But I want to do it in real time i.e. when the employee is getting created/modified/deleted in sap hr, my program should receive all the values and do the changes in ldap at the same time.
What all options do i have to do this?
I am new to sap hr.
Regards,
Nilz

Hi Nilesh
U can take help of Standard Events in SAP.
Go to Tcode SWELS.Then Activate Event trace.
Go and do creation/modification/deletion for employees and Check which allevents are getting triggered in Tcode SWEL.
This might give U an Initial idea how to go about this.
