What are the ramifications if I choose to deauthorize all of my computers.

I have given away my old pcs but did not deauthoize them beforehand and have now reached the 5 computer limit but need to authorize my new PC's includeing a mac mini. I don't want to lose my old media

No it doesn't affect your files.
Authorization and Deauthorization
Macs: iTunes Store- About authorization and deauthorization.
Windows: How to Authorize or Deauthorize iTunes | PCWorld.
In iTunes you use the Authorize This Computer or De-authorize This Computer option under the Store menu in iTunes' menubar. For Windows use the ALT-S keys to access it.
More On De-authorizing Computers (contributed by user John Galt)
You can de-authorize individual computers, but only by using those computers. The only other option is to "de-authorize all" from your iTunes account.
1. Open iTunes on a computer
2. From the Store menu, select "View my Account..."
3. Sign in with your Apple ID and password.
4. Under "Computer Authorizations" select "De-authorize All".
5. Authorize each computer you still have, as you may require.
You may only do this once per year.
After you "de-authorize all" your authorized computers, re-authorize each one as required.
If you have de-authorized all computers and need to do it again, but your year has not elapsed, then contact: Apple - Support - iTunes - Contact Us.

What are the ramification of changing the default installation path?

Some of the users in my agency would like to standardize the installation path so it doesn't change when we upgrade from one version to another. There are other applications that use Adobe Reader and Adobe Acrobat Pro, and a standard path would be helpful. What are the ramification for security and quarterly updates?
We are on Win 7 Pro SP1, mostly 32-bit.

I tend to agree, and strongly recommended against it. Especially since Adobe products can be finicky. And the path that they have to update is not dynamic, unfortunately.
Thanks.

What are the ramifications of removing owa.num_cgi_vars :=0; ??

Hello All,
Hoping someone can help me with this...
changed my character set from WE8ISO8859P1 to AL32UTF8.
After this many pl/sql procedures would fail with:
ERROR Message:
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "SYS.HTP", line 1526
ORA-06512: at "SYS.HTP", line 1735
ORA-06512: at "SYS.HTP", line 594
ORA-06512: at line 5
The fix from Oracle was:
SQL> set serveroutput on
begin
owa.num_cgi_vars := 0;
HTP.HTBUF_LEN := 84;
htp.init;
htp.htmlopen;
htp.p(rpad('.',128,'.'));
htp.htmlclose;
owa_util.showpage;
end;
This works fine for most of our applications, however some only work ok when I take out the owa.num_cgi_vars := 0;
above.
I'd like to remove it altogether as it works for both sets of applications when I take that line out.

What is it doing?The question is WTF ARE YOU DOING!?
It seems you are clueless as to what a web-enabled procedure is. How these need to be called and used. And not calling these from a proper environment. And what, do you copy the entire HTML buffer (in expensive PGA server memory) to the DBMS_OUTPUT buffer (in expensive PGA server memory) in order for the client to access the HTML output?
As for that static variable. It sets the number of CGI (Common Gateway Interface) parameters that are the in the CGI name-value arrays.

What are the ramifications of removing items from Usage Settings?

When attempting to download and install the latest upgrade to my iPad, I received a message that I needed at least 3.8 GB to install the upgrade. Then it recommended removing items in the Usage Settings.
I'm primarily concerned the process could disrupt my large music library.
If I backup my iPad, remove the music from the iPad Usage Settings, and install the upgrade, can I then restore the music?

" ... restore the music" -- to your iPad?
The upgrade requires more space than the older software you have. You should plan to keep less data on your iPad than you had before the upgrade.

Slow Boot Up, Slow Login caused by AHCI so we used IDE Emulator. What is the ramification of that?

Hi,
We have Windows 7 SP1 Enterprise and x64 machines and we have slow boot up and slow login issue for a while. We thought it was clearly group policy causing it but it can be misleading because we have other machines that use the same
GPO but has no issue. On the other hand, the problem is prominent with a specific HP Model (Elitedesk 800G1 SFF) so when we focused on that model, we reinstalled/reformat the computer but to no avail, the machine would still be be slow as soon as it
joins the domain. The other option is to minize the services and startup items, but we can prove that other machines boot up fine with all the services and startup items running. So "Msconfig" helps but as much as possible, we don't want
to do this because we have several computers with slow issues. We also installed KB2775511 but we don't get consistent result.
What gave us consistent result was changing the BIOS setting from AHCI to IDE but I would like to know what are the ramification of not using AHCI. Our new machines were delivered with this BIOS setting so we suppose that this is the most appropriate
setting however, it screws up other things.
What are we missing, how different is the performance and is this change not recommended? Any thoughts?
Thanks!

HT204053 What are the pros and cons of 1) choosing to use the SAME Apple ID for iCloud services on one side, and purchases on the iTunes Store, App Store, and iBookstore, on the other side; or 2) to have and use two separate Apple Ids for these "two sides

All is in the title, so I repeat it below with a better identation.
What are the pros and cons of
1) choosing to use the SAME
Apple ID for iCloud services on one side, and
purchases on the iTunes Store, App Store, and iBookstore, on the other side; or
2) to have and use two separate Apple Ids for these "two sides"?
P.S.
I have loads and loads of free podcasts in iTunes in my iMac, that are certainly more thant the 5 gigas the iCloud provides for free, so I don't want those to go to the cloud. But this is perhaps a different question...
Also need to mention that I have itunes on a mac, a pc and an iphone.
Sorry to look so silly with this question, but I don't get the "big picture".

You need to create a user account for your wife (or yourself depending on who has the current user account). When syncing, each of you should sign in as a separate user, login to iTunes and then sync. I had this problem when my sister got an iPhone. When we did her initial sync, everything on my iPhone showed up on hers. Apple gave me this solution.

There are many jre exe files: what are the differences and which I choose?

Having some problems, that I will describe in another message, I was looking for the latest jre.
I saw that on www.java.com there is 6 update 1, whereas on www.sun.com there is already 6 update 2. So, I would like to know when an update is made available on www.java.com and through automatic updates?
Also, I saw different names, and I would like to understand in an exact way what are the differences:
jre-6-windows-i586.exe;
jre-6-windows-i586-iftw.exe;
jre-6u1-windows-i586-p-s.exe;
jre-6u1-windows-i586-p-iftw.exe;
jre-6u2-windows-i586-p.exe;
jre-6u2-windows-i586-p-iftw.exe;
I understand that te iftw part means the it is a small download, only the setup module. But why there are some files that end with "-p", some with "-p-s", sm with "-i586"?
Thank You

How to find out what are the interfaces used for Job and Job Codes

HI All,
I just wanted to know how do we find out what are the interfaces used for Job and Job codes .
Thanks In Advance
Sunny

Hi,
Here is an idea for your request.
Basically you can create a simple query on multiprovider 0TCT_MC01.
Filter: you can use a variable for restriction of time ( calday, or calmonth) since you should be interested for a time period.
Choose following characters into your objects:
InfoProvider ( 0TCTIFPROV ) - you can create a variable for choosing infoprovider before query runs.
*Tp.[Type of BI Application Object] 0TCTBISOTYP = filter this with 'QUERY' or whatever your need is.
*BI Application Object 0TCTBISBOBJ, ( this will give you the name of the queries)
In key figures choose, Count for BI Appl. (0TCTWTCOUNT).
(number for query run)
Create a condition , for top 20.
Hope this helps.

What are the roles in CRM implementation Project(all generic extractions)

Hi Gurus,
Now I am placed from a support project from BW (CRM) implementation project(all are generic extractions).
& I am also new to implementation project.
what are the neccessary steps to be taken when we are implementing BW for CRM.
Gurus please clarify my doubts.
1. what are the steps in implementation project in detail(as a developer).
2. what are the sizes of the cubes,ODS & How to decide them.
3. what are the neccessary steps for Master data & Transaction data.
4.How to make the functional specifications for Infoobjects,cubes,ODS,Remote cubes,Multiproviders.
5.can we change to delta loads to full loads if yes what happens to existing data.
6.How flat file extraction used in the case of crm& how to do ascii format.
7.What are the steps to be taken when we are creating Queries & Reports in BW CRM.
It's very urgent.
thanks = points.
Bwcheta.

1. what are the steps in implementation project in detail(as a developer).
U have to basically to the techinal design after understnading the functional designs and implemnet the same( creating infoobjects, datatargets, datasources, queries etc.). Then u have to load data and do the unit testing on the same.
2. what are the sizes of the cubes,ODS & How to decide them.
Completely the business reqmnet and the data that the client wants to load.
3. what are the neccessary steps for Master data & Transaction data.
U have to understand ur master data and transaction data on the basis of whch u have create ur infoobjects and load data in them and finally in the datatarget.
4. can we change to delta loads to full loads if yes what happens to existing data.
Sure u can do that by choosing Full update in the infopkg. It will just load the complete data instead of changed records.
*Hope it helps.

What are the parameters in Call transaction method?

Hi ABAPER'S,
Please give me what are the parameters in call transaction method?
Thanks,
Prakash

Processing batch input data with CALL TRANSACTION USING is the faster of the two recommended data transfer methods. In this method, legacy data is processed inline in your data transfer program.
Syntax:
CALL TRANSACTION <tcode>
USING <bdc_tab>
MODE <mode>
UPDATE <update>
<tcode> : Transaction code
<bdc_tab> : Internal table of structure BDCDATA.
<mode> : Display mode:
A
Display all
E
Display errors only
N
No display
<update> : Update mode:
S
Synchronous
A
Asynchronous
L
Local update
A program that uses CALL TRANSACTION USING to process legacy data should execute the following steps:
Prepare a BDCDATA structure for the transaction that you wish to run.
With a CALL TRANSACTION USING statement, call the transaction and prepare the BDCDATA structure. For example:
CALL TRANSACTION 'TFCA' USING BDCDATA
MODE 'A'
UPDATE 'S'.
MESSAGES INTO MESSTAB.
IF SY-SUBRC <> 0.
<Error_handling>.
ENDIF.
The MODE Parameter
You can use the MODE parameter to specify whether data transfer processing should be displayed as it happens. You can choose between three modes:
A Display all. All screens and the data that goes in them appear when you run your program.
N No display. All screens are processed invisibly, regardless of whether there are errors or not. Control returns to your program as soon as transaction processing is finished.
E Display errors only. The transaction goes into display mode as soon as an error in one of the screens is detected. You can then correct the error.
The display modes are the same as those that are available for processing batch input sessions.
The UPDATE Parameter
You use the UPDATE parameter to specify how updates produced by a transaction should be processed. You can select between these modes:
A Asynchronous updating. In this mode, the called transaction does not wait for any updates it produces to be completed. It simply passes the updates to the SAP update service. Asynchronous processing therefore usually results in faster execution of your data transfer program.
Asynchronous processing is NOT recommended for processing any larger amount of data. This is because the called transaction receives no completion message from the update module in asynchronous updating. The calling data transfer program, in turn, cannot determine whether a called transaction ended with a successful update of the database or not.
If you use asynchronous updating, then you will need to use the update management facility (Transaction SM12) to check whether updates have been terminated abnormally during session processing. Error analysis and recovery is less convenient than with synchronous updating.
S Synchronous updating. In this mode, the called transaction waits for any updates that it produces to be completed. Execution is slower than with asynchronous updating because called transactions wait for updating to be completed. However, the called transaction is able to return any update error message that occurs to your program. It is much easier for you to analyze and recover from errors.
L Local updating. If you update data locally, the update of the database will not be processed in a separate process, but in the process of the calling program. (See the ABAP keyword documentation on SET UPDATE TASK LOCAL for more information.)
The MESSAGES Parameter
The MESSAGES specification indicates that all system messages issued during a CALL TRANSACTION USING are written into the internal table <MESSTAB> . The internal table must have the structure BDCMSGCOLL .
You can record the messages issued by Transaction TFCA in table MESSTAB with the following coding:
(This example uses a flight connection that does not exist to trigger an error in the transaction.)
DATA: BEGIN OF BDCDATA OCCURS 100.
INCLUDE STRUCTURE BDCDATA.
DATA: END OF BDCDATA.
DATA: BEGIN OF MESSTAB OCCURS 10.
INCLUDE STRUCTURE BDCMSGCOLL.
DATA: END OF MESSTAB.
BDCDATA-PROGRAM = 'SAPMTFCA'.
BDCDATA-DYNPRO = '0100'.
BDCDATA-DYNBEGIN = 'X'.
APPEND BDCDATA.
CLEAR BDCDATA.
BDCDATA-FNAM = 'SFLIGHT-CARRID'.
BDCDATA-FVAL = 'XX'.
APPEND BDCDATA.
BDCDATA-FNAM = 'SFLIGHT-CONNID'.
BDCDATA-FVAL = '0400'.
APPEND BDCDATA.
CALL TRANSACTION 'TFCA' USING BDCDATA MODE 'N'
MESSAGES INTO MESSTAB.
LOOP AT MESSTAB.
WRITE: / MESSTAB-TCODE,
MESSTAB-DYNAME,
MESSTAB-DYNUMB,
MESSTAB-MSGTYP,
MESSTAB-MSGSPRA,
MESSTAB-MSGID,
MESSTAB-MSGNR.
ENDLOOP.
The following figures show the return codes from CALL TRANSACTION USING and the system fields that contain message information from the called transaction. As the return code chart shows, return codes above 1000 are reserved for data transfer. If you use the MESSAGES INTO <table> option, then you do not need to query the system fields shown below; their contents are automatically written into the message table. You can loop over the message table to write out any messages that were entered into it.
Return codes:
Value
Explanation
0
Successful
<=1000
Error in dialog program
> 1000
Batch input error
System fields:
Name:
Explanation:
SY-MSGID
Message-ID
SY-MSGTY
Message type (E,I,W,S,A,X)
SY-MSGNO
Message number
SY-MSGV1
Message variable 1
SY-MSGV2
Message variable 2
SY-MSGV3
Message variable 3
SY-MSGV4
Message variable 4
Error Analysis and Restart Capability
Unlike batch input methods using sessions, CALL TRANSACTION USING processing does not provide any special handling for incorrect transactions. There is no restart capability for transactions that contain errors or produce update failures.
You can handle incorrect transactions by using update mode S (synchronous updating) and checking the return code from CALL TRANSACTION USING. If the return code is anything other than 0, then you should do the following:
write out or save the message table
use the BDCDATA table that you generated for the CALL TRANSACTION USING to generate a batch input session for the faulty transaction. You can then analyze the faulty transaction and correct the error using the tools provided in the batch input management facility.

What are the major process to transfer the data from legacy to sap system.

What are the major process to transfer the data from legacy to sap system using BDC at Real Time only?

hi,
BATCH DATA COMMUNICATION
main methods are:
1. SESSION METHOD
2. CALL TRANSACTION
3. DIRECT INPUT
Advantages offered by BATCH INPUT method:
1. Can process large data volumes in batch.
2. Can be planned and submitted in the background.
3. No manual interaction is required when data is transferred.
4. Data integrity is maintained as whatever data is transferred to the table is through transaction. Hence batch input data is submitted to all the checks and validations.
To implement one of the supported data transfers, you must often write the program that exports the data from your non-SAP system. This program, known as a data transfer program must map the data from the external system into the data structure required by the SAP batch input program.
The batch input program must build all of the input to execute the SAP transaction.
Two main steps are required:
To build an internal table containing every screen and every field to be filled in during the execution of an SAP transaction.
To pass the table to SAP for processing.
Prerequisite for Data Transfer Program
Writing a Data Transfer Program involves following prerequisites:
Analyzing data from local file
Analyzing transaction
Analyzing transaction involves following steps:
The transaction code, if you do not already know it.
Which fields require input i.e., mandatory.
Which fields can you allow to default to standard values.
The names, types, and lengths of the fields that are used by a transaction.
Screen number and Name of module pool program behind a particular transaction.
To analyze a transaction::
Start the transaction by menu or by entering the transaction code in the command box.
(You can determine the transaction name by choosing System Status.)
Step through the transaction, entering the data will be required for processing your batch input data.
On each screen, note the program name and screen (dynpro) number.
(dynpro = dyn + pro. Dyn = screen, pro = number)
Display these by choosing System Status. The relevant fields are Program (dynpro) and Dynpro number. If pop-up windows occur during execution, you can get the program name and screen number by pressing F1 on any field or button on the screen.
The technical info pop-up shows not only the field information but also the program and screen.
For each field, check box, and radio button on each screen, press F1 (help) and then choose Technical Info.
Note the following information:
- The field name for batch input, which youll find in its own box.
- The length and data type of the field. You can display this information by double clicking on the Data Element field.
Find out the identification code for each function (button or menu) that you must execute to process the batch-input data (or to go to new screen).
Place the cursor on the button or menu entry while holding down the left mouse button. Then press F1.
In the pop-up window that follows, choose Technical info and note the code that is shown in the Function field.
You can also run any function that is assigned to a function key by way of the function key number. To display the list of available function keys, click on the right mouse button. Note the key number that is assigned to the functions you want to run.
Once you have program name, screen number, field name (screen field name), you can start writing.
DATA TRANSFER program.
Declaring internal table
First Integral Table similar to structure like local file.
Declaring internal table like BDCDATA
The data from internal table is not transferred directly to database table, it has to go through transaction. You need to pass data to particular screen and to particular screen-field. Data is passed to transaction in particular format, hence there is a need for batch input structure.
The batch input structure stores the data that is to be entered into SAP system and the actions that are necessary to process the data. The batch input structure is used by all of the batch input methods. You can use the same structure for all types of batch input, regardless of whether you are creating a session in the batch input queue or using CALL TRANSACTION.
This structure is BDCDATA, which can contain the batch input data for only a single run of a transaction. The typical processing loop in a program is as follows:
Create a BDCDATA structure
Write the structure out to a session or process it with CALL TRANSACTION USING; and then
Create a BDCDATA structure for the next transaction that is to be processed.
Within a BDCDATA structure, organize the data of screens in a transaction. Each screen that is processed in the course of a transaction must be identified with a BDCDATA record. This record uses the Program, Dynpro, and Dynbegin fields of the structure.
The screen identifier record is followed by a separate BDCDATA record for each value, to be entered into a field. These records use the FNAM and FVAL fields of the BDCDATA structure. Values to be entered in a field can be any of the following:
Data that is entered into screen fields.
Function codes that are entered into the command field. Such function codes execute functions in a transaction, such as Save or Enter.
The BDCDATA structure contains the following fields:
PROGRAM: Name of module pool program associated with the screen. Set this field only for the first record for the screen.
DYNPRO: Screen Number. Set this field only in the first record for the screen.
DYNBEGIN: Indicates the first record for the screen. Set this field to X, only for the first record for the screen. (Reset to (blank) for all other records.)
FNAM: Field Name. The FNAM field is not case-sensitive.
FVAL: Value for the field named in FNAM. The FVAL field is case-sensitive. Values assigned to this field are always padded on the right, if they are less than 132 characters. Values must be in character format.
Transferring data from local file to internal table
Data is uploaded to internal table by UPLOAD of WS_UPLOAD function.
Population of BDCDATA
For each record of internal table, you need to populate Internal table, which is similar to BDCDATA structure.
All these five initial steps are necessary for any type of BDC interface.
DATA TRANSFER program can call SESSION METHOD or CALL TRANSACTION. The initial steps for both the methods are same.
First step for both the methods is to upload the data to internal table. From Internal Table, the data is transferred to database table by two ways i.e., Session method and Call transaction.
SESSION METHOD
About Session method
In this method you transfer data from internal table to database table through sessions.
In this method, an ABAP/4 program reads the external data that is to be entered in the SAP System and stores the data in session. A session stores the actions that are required to enter your data using normal SAP transaction i.e., Data is transferred to session which in turn transfers data to database table.
Session is intermediate step between internal table and database table. Data along with its action is stored in session i.e., data for screen fields, to which screen it is passed, the program name behind it, and how the next screen is processed.
When the program has finished generating the session, you can run the session to execute the SAP transactions in it. You can either explicitly start and monitor a session or have the session run in the background processing system.
Unless session is processed, the data is not transferred to database table.
BDC_OPEN_GROUP
You create the session through program by BDC_OPEN_GROUP function.
Parameters to this function are:
User Name: User name
Group: Name of the session
Lock Date: The date on which you want to process the session.
Keep: This parameter is passed as X when you want to retain session after
processing it or to delete it after processing.
BDC_INSERT
This function creates the session & data is transferred to Session.
Parameters to this function are:
Tcode: Transaction Name
Dynprotab: BDC Data
BDC_CLOSE_GROUP
This function closes the BDC Group. No Parameters.
Some additional information for session processing
When the session is generated using the KEEP option within the BDC_OPEN_GROUP, the system always keeps the sessions in the queue, whether it has been processed successfully or not.
However, if the session is processed, you have to delete it manually. When session processing is completed successfully while KEEP option was not set, it will be removed automatically from the session queue. Log is not removed for that session.
If the batch-input session is terminated with errors, then it appears in the list of INCORRECT session and it can be processed again. To correct incorrect session, you can analyze the session. The Analysis function allows to determine which screen and value has produced the error. If you find small errors in data, you can correct them interactively, otherwise you need to modify batch input program, which has generated the session or many times even the data file.
CALL TRANSACTION
About CALL TRANSACTION
A technique similar to SESSION method, while batch input is a two-step procedure, Call Transaction does both steps online, one after the other. In this method, you call a transaction from your program by
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>
Messages into <MSGTAB>.
Parameter 1 is transaction code.
Parameter 2 is name of BDCTAB table.
Parameter 3 here you are specifying mode in which you execute transaction
A is all screen mode. All the screen of transaction are displayed.
N is no screen mode. No screen is displayed when you execute the transaction.
E is error screen. Only those screens are displayed wherein you have error record.
Parameter 4 here you are specifying update type by which database table is updated.
S is for Synchronous update in which if you change data of one table then all the related Tables gets updated. And sy-subrc is returned i.e., sy-subrc is returned for once and all.
A is for Asynchronous update. When you change data of one table, the sy-subrc is returned. And then updating of other affected tables takes place. So if system fails to update other tables, still sy-subrc returned is 0 (i.e., when first table gets updated).
Parameter 5 when you update database table, operation is either successful or unsuccessful or operation is successful with some warning. These messages are stored in internal table, which you specify along with MESSAGE statement. This internal table should be declared like BDCMSGCOLL, a structure available in ABAP/4. It contains the following fields:
1. Tcode: Transaction code
2. Dyname: Batch point module name
3. Dynumb: Batch input Dyn number
4. Msgtyp: Batch input message type (A/E/W/I/S)
5. Msgspra: Batch input Lang, id of message
6. Msgid: Message id
7. MsgvN: Message variables (N = 1 - 4)
For each entry, which is updated in database, table message is available in BDCMSGCOLL. As BDCMSGCOLL is structure, you need to declare a internal table which can contain multiple records (unlike structure).
Steps for CALL TRANSACTION method
1. Internal table for the data (structure similar to your local file)
2. BDCTAB like BDCDATA
3. UPLOAD or WS_UPLOAD function to upload the data from local file to itab. (Considering file is local file)
4. Loop at itab.
Populate BDCTAB table.
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>.
Refresh BDCTAB.
Endloop.
(To populate BDCTAB, You need to transfer each and every field)
The major differences between Session method and Call transaction are as follows:
SESSION METHOD CALL TRANSACTION
1. Data is not updated in database table unless Session is processed. Immediate updation in database table.
2. No sy-subrc is returned. Sy-subrc is returned.
3. Error log is created for error records. Errors need to be handled explicitly
4. Updation in database table is always synchronous Updation in database table can be synchronous Or Asynchronous.
Error Handling in CALL TRANSACTION
When Session Method updates the records in database table, error records are stored in the log file. In Call transaction there is no such log file available and error record is lost unless handled. Usually you need to give report of all the error records i.e., records which are not inserted or updated in the database table. This can be done by the following method:
Steps for the error handling in CALL TRANSACTION
1. Internal table for the data (structure similar to your local file)
2. BDCTAB like BDCDATA
3. Internal table BDCMSG like BDCMSGCOLL
4. Internal table similar to Ist internal table
(Third and fourth steps are for error handling)
5. UPLOAD or WS_UPLOAD function to upload the data from the local file to itab. (Considering file is local file)
6. Loop at itab.
Populate BDCTAB table.
Call transaction <tr.code> using <Bdctab>
Mode <A/N/E>
Update <S/A>
Messages <BDCMSG>.
Perform check.
Refresh BDCTAB.
Endloop.
7 Form check.
IF sy-subrc <> 0. (Call transaction returns the sy-subrc if updating is not successful).
Call function Format_message.
(This function is called to store the message given by system and to display it along with record)
Append itab2.
Display the record and message.
DIRECT INPUT
About Direct Input
In contrast to batch input, this technique does not create sessions, but stores the data directly. It does not simulate the online transaction. To enter the data into the corresponding database tables directly, the system calls a number of function modules that execute any necessary checks. In case of errors, the direct input technique provides a restart mechanism. However, to be able to activate the restart mechanism, direct input programs must be executed in the background only. Direct input checks the data thoroughly and then updates the database directly.
You can start a Direct Input program in two ways;
Start the program directly
This is the quickest way to see if the program works with your flat file. This option is possible with all direct input programs. If the program ends abnormally, you will not have any logs telling you what has or has not been posted. To minimize the chance of this happening, always use the check file option for the first run with your flat file. This allows you to detect format errors before transfer.
Starting the program via the DI administration transaction
This transaction restarts the processing, if the data transfer program aborts. Since DI document are immediately posted into the SAP D/B, the restart option prevents the duplicate document posting that occurs during a program restart (i.e., without adjusting your flat file).
Direct input is usually done for standard data like material master, FI accounting document, SD sales order and Classification for which SAP has provided standard programs.
First time you work with the Direct Input administration program, you will need to do some preparation before you can transfer data:
- Create variant
- Define job
- Start job
- Restart job
Common batch input errors
- The batch input BDCDATA structure tries to assign values to fields which do not exist in the current transaction screen.
- The screen in the BDCDATA structure does not match the right sequence, or an intermediate screen is missing.
- On exceptional occasions, the logic flow of batch input session does not exactly match that of manual online processing. Testing the sessions online can discover by this.
- The BDCDATA structure contains fields, which are longer than the actual definition.
- Authorization problems.
RECORDING A BATCH INPUT
A B recording allows you to record a R/3 transaction and generate a program that contains all screens and field information in the required BDC-DATA format.
You can either use SHDB transaction for recording or
SYSTEM ? SERVICES ? BATCH INPUT ? EDIT
And from here click recording.
Enter name for the recording.
(Dates are optional)
Click recording.
Enter transaction code.
Enter.
Click Save button.
You finally come to a screen where, you have all the information for each screen including BDC_OKCODE.
Click Get Transaction.
Return to BI.
Click overview.
Position the cursor on the just recorded entry and click generate program.
Enter program name.
Click enter
The program is generated for the particular transaction.
BACKGROUND PROCESSING
Need for Background processing
When a large volume of data is involved, usually all batch inputs are done in background.
The R/3 system includes functions that allow users to work non-interactively or offline. The background processing systems handle these functions.
Non-interactively means that instead of executing the ABAP/4 programs and waiting for an answer, user can submit those programs for execution at a more convenient planned time.
There are several reasons to submit programs for background execution.
The maximum time allowed for online execution should not exceed 300 seconds. User gets TIMEOUT error and an aborted transaction, if time for execution exceeds 300 seconds. To avoid these types of error, you can submit jobs for background processing.
You can use the system while your program is executing.
This does not mean that interactive or online work is not useful. Both type of processing have their own purposes. Online work is the most common one entering business data, displaying information, printing small reports, managing the system and so on. Background jobs are mainly used for the following tasks; to process large amount of data, to execute periodic jobs without human intervention, to run program at a more convenient, planned time other than during normal working hours i.e., Nights or weekends.
The transaction for background processing is SM36.
Or
Tools ? Administration ? Jobs ? Define jobs
Or
System ? services ? Jobs
Components of the background jobs
A job in Background processing is a series of steps that can be scheduled and step is a program for background processing.
Job name. Define the name of assigned to the job. It identifies the job. You can specify up to 32 characters for the name.
Job class. Indicates the type of background processing priority assigned to the job.
The job class determines the priority of a job. The background system admits three types of job classes: A B & C, which correspond to job priority.
Job steps. Parameters to be passed for this screen are as follows:
Program name.
Variant if it is report program
Start criteria for the job: Option available for this are as follows:
Immediate - allows you to start a job immediately.
Date/Time - allows you to start a job at a specific name.
After job - you can start a job after a particular job.
After event - allows you to start a job after a particular event.
At operation mode - allows you to start a job when the system switches to a particular operation mode.
Defining Background jobs
It is two step process: Firstly, you define the job and then release it.
When users define a job and save it, they are actually scheduling the report i.e., specifying the job components, the steps, the start time.
When users schedule program for background processing, they are instructing the system to execute an ABAP/4 report or an external program in the background. Scheduled jobs are not executed until they are released. When jobs are released, they are sent for execution to the background processing system at the specified start time. Both scheduling and releasing of jobs require authorizations.
HANDLING OF POP UP SCREEN IN BDC
Many times in transaction pop up screen appears and for this screen you dont pass any record but some indication to system telling it to proceed further. For example: The following screen
To handle such screen, system has provided a variable called BDC_CURSOR. You pass this variable to BDCDATA and process the screen.
Usually such screen appears in many transactions, in this case you are just passing information, that YES you want to save the information, that means YES should be clicked. So you are transferring this information to BDCDATA i.e., field name of YES which is usually SPOT_OPTION. Instead of BDC_OKCODE, you are passing BDC_CURSOR.
BDC_CURSOR is also used to place cursor on particular field.
A simple transaction where you are entering customer number on first screen and on next screen data is displayed for the particular customer number. Field, which we are changing here, are name and city. When you click on save, the changed record gets saved.
Prerequisite to write this BDC interface as indicated earlier is:
1. To find screen number
2. To find screen field names, type of the field and length of the field.
3. To find BDC_OKCODE for each screen
4. Create flat file.
generally Batch Input usually are used to transfer large amount of data. For example you are implementing a new SAP project, and of course you will need some data transfer from legacy system to SAP system.
CALL TRANSACTION is used especially for integration actions between two SAP systems or between different modules. Users sometimes wish to do something like that click a button or an item then SAP would inserts or changes data automatically. Here CALL TRANSACTION should be considered.
2. Transfer data for multiple transactions usually the Batch Input method is used.
