Can anybody help its urgent error :RPE-02018
Can any body help me inthis error, actually i was executing the mappig on regular basis but today i found this error
" RPE-02018: Oracle Workflow schema OWF_MGR on host ZAINBIDB cannot be accessed using service BIPROD through port 1521. Please check the location details and try again."
Followed by :
"Io exception: Got minus one from a read call."Hi, we have found this error when configuration parameters in database where not correct. Each time a process flow with a lot of process in parallel was executed, a process failed.
I can't remember the exact parameter to change to correct this error (we had some other errors due to configuration parameters) but I think it was by changing the optimizer_mode to FIRST_ROWS. Ask your DBA to take a look to DB parameters and look for the error message in metalink, I think there's an entry for this error.

hi everybody in the group have to attend the Accenture walk in this Saturday on abap.
pls anybody can tellme
how will be the interview?
what will be the possible questions may raised by them?Hi Sridhar,
MAY BE THIS WILL HELP YOU
ABAP / 4 INTERVIEW QUESTIONS WITH ANSWERS
1) What is SAP R/3?
Ans SAP R/3 refers to Systems Application and Product for data processing Real-time having a 3 tier architecture i.e. Presentation layer, Application layer and Database layer.
2) What are the programming standards followed?
3) What are the contents in technical specifications?
Ans There are five contents in Technical Settings: Data Class, Size Category, Buffering Permission, Buffering Type and Logging.
4) What is an instance?
Ans When you call a function module, an instance of its function group plus its data, is loaded into the memory area of the internal session. An ABAP program can load several instances by calling function modules from different function groups.
5) How to take care of performance in ABAP Development?
6) What is Function group? Difference between function group and function module?
Ans Function Groups act as containers for Function Modules that logically belong together.
Function Groups
1) These cannot be defined in a Function Module.
2) It cannot be called.
3) They are containers for Function Module.
Function Modules
1) These must be defined in a Function Group.
2) It can be called from any program.
3) They are not containers for Function Group.
7) What is the difference between 'Select single * ' and 'Select upto 1 rows'?
Ans Select single * The result of the selection should be a single entry. If it is not possible to identify a unique entry, the system uses the first line of the selection. For e.g.
DATA : ITAB TYPE ZREKHA_EMP.
SELECT SINGLE * FROM ZREKHA_EMP INTO ITAB
WHERE EMPNO = 00101 AND DEPTNO = 0010.
WRITE : / ITAB-EMPNO, ITAB-EMPNAME,ITAB-DEPTNO.
Select upto 1 rows -
8) What Function does data dictionary perform?
Ans Central information repository for application and system data. The ABAP Dictionary contains data definitions (metadata) that allow you to describe all of the data structures in the system (like tables, views, and data types) in one place. This eliminates redundancy.
9) Difference between domain and data element? What are aggregate object?
Ans Domain - Specifies the technical attributes of a data element - its data type, length, possible values, and appearance on the screen. Each data element has an underlying domain. A single domain can be the basis for several data elements. Domains are objects in the ABAP Dictionary.
Data Element - Describes the business function of a table field. Its technical attributes are based on a domain, and its business function is described by its field labels and documentation.
Aggregate Object Views, Match Code and Lock objects are called aggregate objects because they are formed from several related table.
10) What is view? Different types of view. Explain?
Ans View - A view is a virtual table containing fields from one or more tables. A virtual table that does not contain any data, but instead provides an application-oriented view of one or more ABAP Dictionary tables.
Different Types of View:
1) Maintenance
2) Database It is on more than two tables.
3) Projection It is only on one table.
4) Help
11) Can u print decimals in type N? What is difference between float and packed data type?
Ans No, we cannot print decimals in type N because decimal places are not permitted with N
data type.
Float Data Type: It cannot be declared in Parameters.
Packed Number: It can be declared in Parameters. For e.g.
PARAMETERS : A(4) TYPE P DECIMALS 2,
B(4) TYPE P DECIMALS 2.
DATA : C(4) TYPE P DECIMALS 2.
C = A + B.
WRITE : / THE SUM IS , C.
12) What is step-loop? Explain all the steps?
Ans A step loop is a repeated series of field-blocks in a screen. Each block can contain one or more fields, and can extend over more than one line on the screen.
Step loops as structures in a screen do not have individual names. The screen can contain more than one step-loop, but if so, you must program the LOOP...ENDLOOPs in the flow logic accordingly. The ordering of the LOOP...ENDLOOPs must exactly parallel the order of the step loops in the screen. The ordering tells the system which loop processing to apply to which loop. Step loops in a screen are ordered primarily by screen row, and secondarily by screen column.
Transaction TZ61 (development class SDWA) implements a step loop version of the table you saw in transaction TZ60.
Static and Dynamic Step Loops
Step loops fall into two classes: static and dynamic. Static step loops have a fixed size that cannot be changed at runtime. Dynamic step loops are variable in size. If the user re-sizes the window, the system automatically increases or decreases the number of step loop blocks displayed. In any given screen, you can define any number of static step loops, but only a single dynamic one.
You specify the class for a step loop in the Screen Painter. Each loop in a screen has the attributes Looptype (fixed=static, variable=dynamic) and Loopcount. If a loop is fixed, the Loopcount tells the number of loop-blocks displayed for the loop. This number can never change.
Programming with static and dynamic step loops is essentially the same. You can use both the LOOP and LOOP AT statements for both types.
Looping in a Step Loop
When you use LOOP AT <internal-table> with a step loop, the system automatically displays the step loop with vertical scroll bars. The scroll bars, and the updated (scrolled) table display, are managed by the system.
Use the following additional parameters if desired:
FROM <line1> and TO <line2>
CURSOR <scroll-var>
13) What is the initial value and maximum length of all data type?
Ans
Data Type Initial field length Valid field length Initial value Meaning
Numeric types
I 4 4 0 Integer (whole number)
F 8 8 0 Floating point number
P 8 1 16 0 Packed number
Character types
C 1 1 65535 ' ' Text field (alphanumeric characters)
D 8 8 '00000000' Date field (Format: YYYYMMDD)
N 1 1 65535 '0 0' Numeric text field (numeric characters)
T 6 6 '000000' Time field (format: HHMMSS)
Hexadecimal type
X 1 1 65535 X'0 0' Hexadecimal field
14) What are the ways to find out the tables used in the program?
Ans
15) Can you have two detail lists from the basic list at the same time?
If yes how and if no why?
Ans

CALL SELECTION-SCREEN 500 STARTING AT 10 10.
21) What do you know about a client?
Ans
22) What are the system fields? Explain?
Ans The ABAP system fields are active in all ABAP programs. They are filled by the runtime environment, and you can query their values in a program to find out particular states of the system. Although they are variables, you should not assign your own values to them, since this may overwrite information that is important for the normal running of the program. However, there are some isolated cases in which you may need to overwrite a system variable. For example, by assigning a new value to the field SY-LSIND, you can control navigation within details lists.
23) What is SAP Script? What is the purpose of SAP Script? Difference between
SAP Script and Report?
Ans SAP Script It is the integrated text management system of the SAP R/3 System. Two types PC Editor & Line Editor.
Reports - It is the way to display data fetched from database table onto screen or directly output it to a printer. Two types Classical and Interactive.
24) What is the use of occurs in internal table? Can u change occurs value in program?
Ans Use of Occurs - If you use the OCCURS parameter, the value of the INITIAL SIZE of the table is returned to the variable <n>
Data : Begin of ITAB occurs 0,
End of ITAB.
Occurs or Initial Size to specify the initial amount of memory that should be assigned to the table.
Yes, we can change the occurs value in program but output remains the same.
25) Difference between SY-TABIX and SY-INDEX? Where it is used?
Can u check SY-SUBRC after perform?
Ans SY-TABIX - Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY_INDEX - In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
26) Difference between UPLOAD and WS_UPLOAD?
Ans UPLOAD - File transfer with dialog from presentation server file to internal table. Data which is available in a file on the presentation server is transferred in an internal table. ASCII & Binary files can be transferred.
WS_UPLOAD - To read data from the presentation server into an internal table without a user dialog, use the function module WS_UPLOAD. The most important parameters are listed below.
Parameters Function
CODEPAGE Only for upload under DOS: Value IBM
FILENAME Filename
FILETYPE File type

28) What is a Logical Database?
Ans Logical Databases are special ABAP programs that retrieve data and make it available to application programs.
Use of LDB is used to read data from database tables by linking them to executable ABAP programs.
29) What are the events used for Logical Database?
Ans Two Events
1) GET - This is the most important event for executable programs that use a logical database. It occurs when the logical database has read a line from the node <table> and made it available to the program in the work area declared using the statement NODES <table>. The depth to which the logical database is read is determined by the GET statements
2) PUT - The PUT statement directs the program flow according to the structure of
the logical database.
30) What is the difference between Get and Get Late?
Ans GET - After the logical database has read an entry from the node <table>.
GET LATE - After all of the nodes of the logical database have been processed that are below <table> in the database hierarchy.

Ans
58) What is LUW?
Ans Logical Unit of Work
59) Different types of LUWs. What r they?
Ans Two types of LUW are:
1) DB LUW - A database LUW is the mechanism used by the database to ensure that its data is always consistent. A database LUW is an inseparable sequence of database operations that ends with a database commit. The database LUW is either fully executed by the database system or not at all. Once a database LUW has been successfully executed, the database will be in a consistent state. If an error occurs within a database LUW, all of the database changes since the beginning of the database LUW are reversed. This leaves the database in the state it had before the transaction started.
2) SAP LUW - A logical unit consisting of dialog steps, whose changes are written to the database in a single database LUW is called an SAP LUW. Unlike a database LUW, an SAP LUW can span several dialog steps, and be executed using a series of different work processes.

65) What are the difference between call screen and leave screen?
Ans Call Screen: Calling a single screen is a special case of embedding a screen sequence. If you want to prevent the called screen from covering the current screen completely, you can use the CALL SCREEN statement with the STARTING AT and ENDING AT
CALL SCREEN 1000.
CALL SCREEN 1000 STARTING AT 10 10 ENDING AT 20 20.
LEAVE SCREEN statement ends the current screen and calls the subsequent screen.

78) From a table how do u find whether a material is used in another material BOM?
Ans
79) What is read line?
Ans READ LINE and READ CURRENT LINE These statements are used to read data from the lines of existing list levels. These statements are closely connected to the HIDE technique.
80) How u used logical database? How is data transferred to program? Corresponding statement in LDB.
Ans
81) How do u suppress fields on selection screen generated by LDB?
Ans
82) Can there be more than 1 main window in SAP Script?
Ans No, there cannot be more than 1 main window in SAP Script because in WRITE_FORM, it asks for the parameter Window that will create the problem.
WRITE_FORM
Exporting
Element
Window
83) Global and local data in function modules.
Ans
84) What are the differences between SAP memory and ABAP memory?
Ans ABAP Memory is a memory area in the internal session (roll area) of an ABAP program. Data within this area is retained within a sequence of program calls, allowing you to pass data between programs that call one another. It is also possible to pass data between sessions using SAP Memory.
SAP Memory is a memory area to which all sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session (as with ABAP memory) or to pass data from one session to another.
85) What are differences between At selection-screen and At selection-screen output?
Ans AT SELECTION-SCREEN event is triggered in the PAI of the selection screen once the ABAP runtime environment has passed all of the input data from the selection screen to the ABAP program.
AT SELECTION-SCREEN OUTPUT - This event block allows you to modify the selection screen directly before it is displayed.
86) What are the events?
Ans
87) What is get cursor field?
Ans GET CURSOR statement transfers the name of the screen element on which the cursor is positioned during a user action into the variable <f>.
GET CURSOR FIELD <f> [OFFSET <off>] [LINE <lin>] [VALUE <val>] LENGTH <len>].
88) What is the inside concept in select-options?
Ans Select-options specify are displayed on the selection screen for the user to enter values.
Different Properties of Select-options:
1) Visible Length
2) Matchcode Object
3) Memory ID
4) Lowercase
5) Obligatory
6) No Display
7) Modify ID
89) What is the difference between occurs 1 and occurs 2?
Ans
90) What is the difference between Free and Refresh?
Ans Free - You can use FREE to initialize an internal table and release its memory space without first using the REFRESH or CLEAR statement. Like REFRESH, FREE works on the table body, not on the table work area. After a FREE statement, you can address the internal table again. It still occupies the amount of memory required for its header (currently 256 bytes). When you refill the table, the system has to allocate new memory space to the lines.
Refresh - This always applies to the body of the table. As with the CLEAR statement, the memory used by the table before you initialized it remains allocated. To release the memory space, use the statement
91) What are elements?
Ans
92) Can we have more than one selection-screen and how?
Ans Yes, we can have more than one selection screen.
Selection-screen begin of block honey with frame title text-101.
Select-options : deptno for zrekha_deptt-deptno.
Selection-screen end of block honey.
Selection-screen begin of block honey1 with frame title text-102.
Select-options : dname for zrekha_deptt-dname.
Selection-screen end of block honey1.
93) How to declare select-option as a parameter?
Ans SELECT-OPTIONS: specify are displayed on the selection screen for the user to enter values.
Parameters: dname like dept-dname.
Select-options: dname for dept-dname.
94) How can u write programmatically value help to a field without using search help and
match codes?
Ans By using two types of function modules to be called in SAP Script:
1) HELP_OBJECT_SHOW_FOR_FIELD
2) HELP_OBJECT_SHOW
95) What are the differences between SE01, SE09 and SE10?
Ans SE01 - Correction & Transport Organizer
SE09 - Workbench Organizer
SE10 - Customizing Organizer
96) How to set destination?
Ans
97) What are the function module types?
Ans
98) What are tables?
Ans Tables : ZREKHA_EMP.
It creates a structure the table work area in a program for the database tables, views or structure ZREKHA_EMP. The table work area has the same name as the object for which we created it. ZREKHA_EMP must be declared in the ABAP dictionary. The name and sequence of fields in the table work area ZREKHA_EMP corresponds exactly to the sequence of fields in the database table, view definition in the ABAP dictionary.
99) What are client-dependant tables and independent tables?
Ans
100) How to distinguish client-dependant tables from independent tables?
Ans
101) What is the use of Table maintenance allowed?
Ans Mark the Table maintenance allowed flag if users with the corresponding authorization may change the data in the table using the Data Browser (Transaction SE16). If the data in the table should only be maintained with programs or with the table view maintenance transaction (Transaction SM30), you should not set the flag.
102) How to define Selection Screen?
Ans Parameters, Select-options & Selection-Screen
103) What are the check tables and value tables?
Ans Check Table: The ABAP Dictionary allows you to define relationships between tables using foreign keys . A dependent table is called a foreign key table, and the referenced table is called the check table. Each key field of the check table corresponds to a field in the foreign key table. These fields are called foreign key fields. One of the foreign key fields is designated as the check field for checking the validity of values. The key fields of the check table can serve as input help for the check field.
Value Table: Prior to Release 4.0, it was possible to use the value table of a domain to provide input help. This is no longer possible, primarily because unexpected results could occur if the value table had more than one key field. It was not possible to restrict the other key fields, which meant that the environment of the field was not considered, as is normal with check tables.
In cases where this kind of value help was appropriate, you can reconstruct it by creating a search help for the data elements that use the domain in question, and using the value table as the selection method.
Check table will be at field level checking.
Value table will be at domain level checking ex: scarr table is check table for carrid.
104) What is the difference between tables and structures?
Ans Tables:
1) Data is permanently stored in tables in the database.
2) Database tables are generated from them.
Structure:
1) It contains data temporarily during program run-time.
2) No Database tables are generated from it.
105) How to declare one internal table without header line without using structures?
Ans No, we cannot declare internal table without header line and without structure because it gives error ITAB cannot be a table, a reference, a string or contain any of these object.
Code with Header without Structure
TABLES : ZREKHA_EMP.
DATA : ITAB LIKE ZREKHA_EMP OCCURS 0 WITH HEADER LINE.
SELECT * FROM ZREKHA_EMP INTO CORRESPONDING FIELDS OF ITAB.
APPEND ITAB.
ENDSELECT.
LOOP AT ITAB.
WRITE : / ITAB-EMPNO, ITAB-EMPNAME,ITAB-DEPTNO.
ENDLOOP.
Code without Header with Structure
TABLES : ZREKHA_EMP.
DATA : BEGIN OF ITAB OCCURS 0,
EMPNO LIKE XREKHA_EMP-EMPNO,
EMPNAME LIKE XREKHA_EMP-EMPNAME,
DEPTNO LIKE XREKHA_EMP-DEPTNO,
END OF ITAB.
SELECT * FROM ZREKHA_EMP INTO CORRESPONDING FIELDS OF ITAB.
APPEND ITAB.
ENDSELECT.
LOOP AT ITAB.
WRITE : / ITAB-EMPNO, ITAB-EMPNAME,ITAB-DEPTNO.
ENDLOOP.
106) What are lock objects?
Ans Reason for Setting Lock: Suppose a travel agent want to book a flight. The customer wants to fly to a particular city with a certain airline on a certain day. The booking must only be possible if there are still free places on the flight. To avoid the possibility of overbooking, the database entry corresponding to the flight must be locked against access from other transactions. This ensures that one user can find out the number of free places, make the booking, and change the number of free places without the data being changed in the meantime by another transaction.
The R/3 System synchronizes simultaneous access of several users to the same data records with a lock mechanism. When interactive transactions are programmed, locks are set and released by calling function modules (see Function Modules for Lock Requests). These function modules are automatically generated from the definition of lock objects in the ABAP Dictionary.
Two types of Lock: Shared and Exclusive
107) What are datasets? What are the different syntaxes?
Ans The sequential files (ON APPLICATION SERVER) are called datasets. They are used for file handling in SAP.
OPEN DATASET [DATASET NAME] FOR [OUTPUT / INPUT / APPENDING]
IN [BINARY / TEXT] MODE
AT POSITION [POSITION]
MESSAGE [FIELD]
READ DATASET [DATASET NAME] INTO [FIELD]
DELETE DATASET [DATASET NAME]
CLOSE DATASET [DATASET NAME]
TRANSFER [FIELD] TO [DATASET NAME]
108) What are the events we use in dialog programming and explain them?
Ans There are two events in Dialog Programming i.e. screen:
1. PBO (Process Before Output) Before the screen is displayed, the PBO event is processed.
2. PAI (Process After Input) When the user interacts with the screen, the PAI event is processed.
3. POH (Process On Help) - are triggered when the user requests field help (F1). You can program the appropriate coding in the corresponding event blocks. At the end of processing, the system carries on processing the current screen.
4. POV (Process On Value) - are triggered when the user requests possible values help (F4). You can program the appropriate coding in the corresponding event blocks. At the end of processing, the system carries on processing the current screen.
109) What is the difference between OPEN_FORM and CLOSE_FORM?
Ans OPEN_FORM This module opens layout set printing. This function must be called up before we can work with other layout set function like WRITE_FORM.
WRITE_FORM Output text element in form window. The specified element of the layout set window entered is output. The element must be defined in the layout set.
CLOSE_FORM End layout set printing. Form printing started with OPEN_FORM is completed. Possible closing operations on the form last opened are carried out. Form printing must be completed by this function module. If this is not carried out, nothing is printed or displayed on the screen.
110) What are the page windows? How many main windows will be there in a page window?
Ans Page Window: In this window, we define the margins for left, width, upper and height for the layout of Header, Logo, Main, & Footer.
111) What are control events in a loop?
Ans Control level processing is allowed within a LOOP over an internal table. This means that we can divide sequences of entries into groups based on the contents of certain fields.
AT <level>.
<statement block>
ENDAT.
You can react to the following control level changes:
<level> Meaning
FIRST First line of the internal table
LAST Last line of the internal table
NEW <f> Beginning of a group of lines with the same contents in the field <f> and in the fields left of <f>
END Of <f> End of a group of lines with the same contents in the field <f> and in the fields left of <f>
112) How to debugg a script?
Ans Go to SE71, give layout set name, go to utilities select debugger mode on.
113) How many maximum sessions can be open in SAPgui?
Ans There are maximum 6 sessions open in SAPgui. -

When i try to start itunes i get a message saying that the MSVCR80.dll file is missing and to reinstall itunes. When I try to reinstall itunes it tells me that I have an Error 7 (windows error 126). Can anybody tell me what this means? Thanks
Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

Visual C ++ Runtime Library, Runtime Error.. I keep getting this message can anybody help!
Visual C ++ Runtime Library, Runtime error..I keep getting this message can anybody help please !!
What is the /exact/ error? What are your system details? Are you running 32-bit or 64-bit version of the software (if your OS supports it)?
I assume the message you are getting is about the UI runtimes every application needs some version of, which is typically supplied by Visual Studio, though there are redist versions bundled with many apps.
Unfortunately, Windows library management can be a bit of DLL hell (which Microsoft is making an effort to address in Windows 7.) There are many, many references to this with potential fixes, in Microsoft KB articles.
But the first step is good information so you can work from the known to the unknown. -
