1.What is a database? What is DBMS?A datbase is a collection of organized data.
A Database Management System (DBMS) is a system/software that enables you to store, modify, and extract information from a database
2.Why would you choose a database system instead of simply storing the data in Operating system files?In the database, the data is stored at a central location and is shared among multiple users. Thus, the main advantage of DBMS is centralized data management. The centralized nature of database system provides several advantages, which overcome the limitations of the conventional file processing system.
3.What is the difference between Logical Independence and Physical Independence?http://en.wikipedia.org/wiki/Data_independence
4.What are the different types of languages supported in database?SQL
Java
PL/SQL
5.What is meant by data modeling?Data modeling is the process of designing and validating a database.
6.Who are the different types of users accessing the database and in what way?Database Adminnistrators
Developers
End Users(Customers)

  • Sample BW certification questions..can you answer these questions ? please.

    Hi Experts,
    im gonna take SAP BI (C_TBW45_70) certication exam at the end of this month..i found some questions but without answers..
    can anyone answer these questions ?
    1.What are the main motivations for using BI Statistics and the BI Administrator Cockpit
    a)Central point of entry for SAP Netweaver BI Monitoring
    b)Remodeling of IC
    c)improved performance tuning using complete and detailed runtime information on processing in SAP Netweaver BI
    d)İmproved monitoring on Mart Data consistincy using new Technical Content
    2.Within DataSource maintenance in an SAP source system...
    a)...infoobjects can be assigned to the extract structure fields.
    b)...fields can be hidden.During Datasource replication ,these fields are not transferred into SAP Netweaver BI
    c)...the initialization selection can be deleted
    d)...fields can be selected for selection.these fields can be used to request selected data from the SAP source system in an infopacket
    e)...fields can be hidden..In other words , these fiedls are remowed from the extract structure and can only be used for calculation within the user exit during data transfer
    3.Which of the following statements are true regarding the BI Accelerator
    a)BI Accelerator indexes are loaded into the memory of the BI Accelerator
    b)A BI Accelerator index contains all the data of an infocube in a compressed but not aggregated format
    c)One BI Accelerator index is created per aggregate of an infocube
    d)The BI Accelerator is used to improve the read performance of queries on IC and DSO
    e)The BI Accelerator is built using TREX technology but is a seperate installation that cannot be used for standart knowledge management functionality
    4.The APD(Analysis Proses Designer) in sap netweaver provides a mechanism for reading data from a source and then transferring the analytical resource back out to a data target.in this scenerio which of the following are possible data targets of the APD ?
    a)DataSource Object for direct update
    b)Standart DataSource Object
    c)Metadata repository
    d)infoObject master data tables
    e)VirtualProviders
    5.Which of the following statements is true regarding the BI Administration Cockpit architecture ?
    a)Bı Statistic collect runtime and status information on various object in your SAP Netweaver BI system.The technical contect extracts these statistics or accesses them directly for central display in  the BI BI Administration Cockpit
    b)After installation of the technical content datasources on your mySAP ERP source system, you are able to load performance data on mySap ERP transactions to the BI Administration Cockpit.
    c) the BI Administration Cockpit triggers periodci BI Statistics calculation , the results of which are displayed in te Data Warehousing Workbench
    6.in which of the following business scenerios should using Real time Data Acquisition be considered ?
    a) your customer need timely data in their operatinal reporst in SAP Netweaver BI.Direct access is not a viable option because of high resource consumption and high data volumes in the SAP Source system.
    b)the data availability in your customer's source system cannot be foreseen.upon availability the source system shall push the data to a web service DataSource (using SAP Netweaver XI or by directly calling the web service).
    c)your customer uses a single dialog process for transferring data from their SAP source system to SAP Netweaver BI.Because of long processing time during data transfer to SAP Netweaver BI , they want to increase the upload frequency since smaller amount of...
    d)your customer needs current flat file data in their operational reports.the file contain approx. 500 records.at regular 5 minute time interval , the flat file shall be extracted to a DataStore Object for delta calculation for further data targets.
    thanks in advance.
    Apo

    As far I know, what is possible (P), impossible (I) and can be reached from database (DB):
    DB - you would have to create query of groups, where such member was (there are Group History Report
    and Group Membership Change Report out of the box, so suitable data is in DB)
    P - you can specify the Member Resource ID in
    Group Membership Change Report
    P - OOB - Group Membership Change Report
    P/DB - rather searched by query in DB than realizable through OOB Report
    & 6. - OOB it would be hard I think - as you would have to join informations about owners, members of some Sets and MPRs - maybe it could be realizable through DB query, but I am not sure about that.

  • HT3591 I was about to download (buy) some music from ITunes when they said I had to answer these security questions, however I've never answered in my hole apple experience which has left me unable to buy anything because I don't know my security question

    I was about download music when it then asked me for my security questions. The problem for me is that I've never answered these questions ever in my hole apple experience and even if I did, I've 100% completely forgot about them. I then decided to email a link to deactivate my questions however this email from Apple had never come, I'm know left unable to download music, apps, and books.

    You need to manage your Apple ID and change your security question there.

    Oracle 9i Administration, Question 1 of 12
    Q What facility does Oracle provide to detect chained and migrated rows after the proper tables have been created?
    The RDBMS cannot detect this. It must use regular export and import with compress=y to remove chained and migrated rows as part of the regular database.
    The UTLCHAIN utility
    The DBMS_REPAIR package
    The ANALYZE command with the LIST CHAINED ROWS option
    The DBMS_MIG_CHAIN built-in package

    ORA-1628 ... max # extents ... reached for rollback segment ..
    Referring to the scenario above, what do you do differently so that the export is resumed even after getting the space allocation error?
    Use the RESUMABLE=Y option for the export.
    Run the export with the AUTO_ROLLBACK_EXTEND=Y option.
    Increase the rollback segment extents before running the export.
    Use THE RESUME=Y option for the export.
    Monitor the rollback segment usage while the export is running and increase it if it appears to be running out of space.

    u0817000.sql
    Q What command do you use to drop a temporary tablespace and the associated OS files?
    ALTER DATABASE TEMPFILE '/data/oracle/temp01.dbf' DROP;
    ALTER DATABASE DATAFILE '/data/oracle/temp01.dbf' DROP;
    ALTER DATABASE TEMPFILE '/data/oracle/temp01.dbf' DROP INCLUDING DATAFILES;
    ALTER DATABASE DATAFILE '/data/oracle/temp01.dbf' DROP CASCADE;
    ALTER DATABASE DATAFILE '/data/oracle/temp01.dbf' DROP INCLUDING CONTEN
    Q You wish to use a graphical interface to manage database locks and to identify blocking locks.
    Referring to the scenario above, what DBA product does Oracle offer that provides this functionality?

    MAXLOGFILES 5
    MAXLOGMEMBERS 5
    MAXDATAFILES 20
    MAXLOGHISTORY 100
    Referring to the code segment above, how do you change the MAX parameters shown?
    They can be changed using an ALTER SYSTEM command, but the database must be in the NOMOUNT state.
    The MAX parameters cannot be changed without exporting the entire database, re-creating it, and importing.
    They can be changed using an ALTER SYSTEM command while the database is open.
    They can be changed in the init.ora file, but the database must be restarted for the values to take effect.
    They cannot be changed unless you re-create your control file
    Q You need to change the archivelog mode of an Oracle database.
    Referring to the scenario above, what steps do you take before actually changing the archivelog mode?
    Execute the archive log list command
    Start up the instance and mount the database but do not open it.
    Start up the instance and mount and open the database in restricted mode.
    Kill all user sessions to ensure that there is no database activity that might trigger redolog activity.
    Take all tablespaces offline
    Q You are experiencing performance problems due to network traffic. One way to tune this is by setting the SDU size.
    Referring to the scenario above, why do you change the SDU size?
    A high-speed network is available where the data transmission effect is negligible.
    The application can be tuned to account for the delays.
    The requests to the database return small amounts of data as in an OLTP system.
    The data coming back from the server are fragmented into several packets.
    A large number of users are logged on concurrently to the system.
    Q When interpreting statistics from the v$sysstat, what factor do you need to keep in mind that can skew your statistics?
    Choice 1 The statistics are static and must be updated by running the analyze command to include the most recent activity.
    Choice 2 The statistics are only valid as a point in time snapshot of activity.
    Choice 3 The statistics gathered by v$sysstat include database startup activities and database activity that initially populates the database buffer cache and shared pool.
    Choice 4 The statistics do not include administrative users.
    Choice 5 The statistics gathered are based on individual sessions, so you must interpret them based on the activity and application in which the user was involved at the time you pull the statistics.
    Q When interpreting statistics from the v$sysstat, what factor do you need to keep in mind that can skew your statistics?

    Hi
    To reset your security questions you will need to contact apple either by phone or email, many people have asked this question before and most have all ended up contacting apple
    Hope this helps

  • Who can answer these simple questions?

    Please be patient to read the following simple code. The numbers at the beginning of each line are line number. It is part of a code to read record into a file.
    // Fig. 17.4: BankAccountRecord.java
    1 public class BankAccountRecord implements Serializable {
    2 private int account;
    3 private String firstName;
    4 private String lastName;
    5 private double balance;
    public BankAccountRecord()
    6 this( 0, "", "", 0.0 );
    public BankAccountRecord( int acct, String first,
    String last, double bal )
    7 setAccount( acct );
    8 setFirstName( first );
    9 setLastName( last );
    10 setBalance( bal );
    public void setAccount( int acct )
    11 account = acct;
    public void setFirstName( String first )
    12 firstName = first;
    public void setLastName( String last )
    13 lastName = last;
    public void setBalance( double bal )
    14 balance = bal;
    import BankAccountRecord;
    public class CreateSequentialFile extends JFrame {
    private ObjectOutputStream output;
    15 File fileName = fileChooser.getSelectedFile();
    16 output = new ObjectOutputStream(
    new FileOutputStream( fileName ) );
    public void addRecord()
    17 int accountNumber = 0;
    18 BankAccountRecord record;
    19 String fieldValues[] = new String(4);
    20 record = new BankAccountRecord(
    accountNumber, fieldValues[ 1 ],
    fieldValues[ 2 ],
    fieldValues[ 3 ] );
    21 output.writeObject( record );
    22 output.flush();
    My questions are:
    1. BankAccountRecord is a class. After line 18 is excecuted,
    record is an object of BankAccountRecord, right?
    2. Line 20 initialize record, right?
    3. After line 21 is excecuted, what is written to the file?
    It should the record(account, firstName, lastName, balance),
    right? But since BankAccountRecord is a class and record is an object of BankAccountRecord, how about the methods
    of the class BankAccountRecord, for example setAccount( ),
    setFirstName(), setLastName(), setBalance(), are these
    methods also written into the file? I think not. But why?

    1) After line 18, record is a reference to a BankAccountRecord with an undefined value. That is, it may be null, it may hold garbage, but you can't use it. Local variables are not initialized. Members are initialized to (0, 0.0, false, null) as appropriate for type, as are array elements.
    2) Line 20 assigns record to refer to a newly created BankAccountRecord object.
    3) Methods are not written out on serialization, only the state of the object--i.e. it's member variables. The method definitions are stored in the .class file that was created when you compiled the class. (If you really wanted to you could override the method (writeObject, I think) and write out whatever you wanted, but there's not need to serialize the method definitions, since they're part of the class.)

    1.Types of Joins in sap-abap?
    2.What is the typical structure of an ABAP program?
    3.Can you create a table with fields not referring to data elements?
    4.What is an interactive report? What is the obvious diff of such report compared with classical type reports?
    5.What is a drill down report?
    What are the exceptions in function module?
    6. What are ranges? What are number ranges?
    7. What are select options and what is the diff from parameters?
    8.What is the client concept in SAP? What is the meaning of client independent?
    9.What specific statements do you using when writing a drill down report?

    HI,
    <b>1. there are two types of join inner and left outer joins.
    2. A ABAP program is typical contains different events. like 'INITILIZATION', 'TOP-OF-PAGE', 'START-OF-SELECTION'. these events together makes the flow logic of program.
    3. yes we can.
    4. interactive reports are that like we have a report in which we are displaying vendors in lines. now by clicking on some vendor all detail of that vendor will be displayed. Classical reports did'nt have details of data showed they are static to 1 level.
    5. there is no difference between interactive and drill down report.
    5. Exceptions in function module are different error types that happen in function module and they will be return to calling program so the program know the exact reason of function module failure.
    6. ranges are same as select-options but will no display.
    7. answer in previous thread.
    8. clients are used to divide server for multiple purposes like in development server we have two clients 100 and 200. 100 will be developement client and 200 will be for testing. ABAP workbench is client independent means if you have developed a program in one client it will be avaialbe in all clients. while customization is client dependent. you can customize different clients differently.

  • Can any one answer these interview questions

    CTS INTERVIEW QUESTIONS( 24/02/07 )
    1.  What is the difference b/w classical report and ALV  report and in classical report can we produce output more than 255 characters?
    2.  Did you used classes to create ALV reports  and how is superior over using    function modules in ALV report generation?
    3.  If we don't know the  exact number of blocks to be generated then Can we generate the output with different number of blocks in 
         ALV   reports?
    4.  In report if we have write statements in initialization, top of page and in start of selection then which event is first excuted and what
         is  the output?
    5.  In interactive report what is the use of exit key word?
    6.  what are nested structures and deep structures?
    7.  how can we write BDC program to  upload  data from  CSV, XL, TAB delimeter type flat files?
    8.  In BDC if the flat file consist of header and multiple line items then how to upload the load, does we create a single internal table for
         both header and body or different internal tables?
    9.  In call transaction and session method which method is prefered one?
    10. why can't we use call transaction method to upload large amount of data?

    15. what are the different types of performance techniques?
    16. can we do modifications on output of   ALV reports, how?
    17. what are the classes that are used in ALV reporting?

    hi bhushan,
    1. What is the difference b/w classical report and ALV report and in classical report can we produce output more than 255 characters?
    Ans. Classical report ---Consist of one program that create a single list.This means that when list is displayed,it has to contain all data
    requested,regardless of the number of details the user wants to see.This procdeure may result in extensive and cluttered list from which the user has to pick the relvent data.(desired selection much be made before hand).
    Mian thing in classical report is it is not interactive(you will have cluttered information).
    Alv report _ IS interactive reporting (it is a set of function modules).(in alv we use both classical and interactive).
    in classical report we can't produce output more than 255 characters(but in ALV we can have the report contains columns more than 255 characters in length).
    ALV is very efficient tool for dynamically sorting and arranging the columns from a report output.
    2. Did you used classes to create ALV reports and how is superior over using function modules in ALV report generation?
    Ans. its upto you(did you use classes in ALV then say yes)
    3. If we don't know the exact number of blocks to be generated then Can we generate the output with different number of blocks in
    ALV reports?
    4. In report if we have write statements in initialization, top of page and in start of selection then which event is first excuted and what
    is the output?
    ANS. TOP_OF_PAGE is triggered.
    this event is triggered with the first WRITE statement or whenever new page is triggered. if you donts have any write statement before top-of-page or
    in start-of-selection then this event is not triggered.
    5. In interactive report what is the use of exit key word?
    Ans.
    6. what are nested structures and deep structures?
    7. how can we write BDC program to upload data from CSV, XL, TAB delimeter type flat files?
    Ans use FM 'GUI_UPLOAD'(CSV/TAB is .XLS)
    CALL FUNCTION 'GUI_UPLOAD'
    EXPORTING
    filename = 'D:PERSONALF1.XLS'
    FILETYPE = 'ASC'
    HAS_FIELD_SEPARATOR = ' '
    HEADER_LENGTH = 0
    READ_BY_LINE = 'X'
    DAT_MODE = ' '
    CODEPAGE = ' '
    IGNORE_CERR = ABAP_TRUE
    REPLACEMENT = '#'
    CHECK_BOM = ' '
    VIRUS_SCAN_PROFILE =
    NO_AUTH_CHECK = ' '
    IMPORTING
    FILELENGTH =
    HEADER =
    tables
    data_tab = itab[]
    EXCEPTIONS
    FILE_OPEN_ERROR = 1
    FILE_READ_ERROR = 2
    NO_BATCH = 3
    GUI_REFUSE_FILETRANSFER = 4
    INVALID_TYPE = 5
    NO_AUTHORITY = 6
    UNKNOWN_ERROR = 7
    BAD_DATA_FORMAT = 8
    HEADER_NOT_ALLOWED = 9
    SEPARATOR_NOT_ALLOWED = 10
    HEADER_TOO_LONG = 11
    UNKNOWN_DP_ERROR = 12
    ACCESS_DENIED = 13
    DP_OUT_OF_MEMORY = 14
    DISK_FULL = 15
    DP_TIMEOUT = 16
    OTHERS = 17
    IF sy-subrc <> 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
    WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    You can also use.
    Use GUI_UPLOAD FM with exporting parameter
    has_field_separator = 'X'
    8. In BDC if the flat file consist of header and multiple line items then how to upload the load, does we create a single internal table for
    both header and body or different internal tables?

    http://www.sap-img.com/abap/bdc-example-using-table-control-in-bdc.htm
    When you have enter multiple line in BDC for a table control use call transaction tcode using i_bdcdata options from opt message into i_messages.
    Check the below example.
    data: lws_cnt type char2,
    lws_field type char15.
    LOOP AT i_invoicing_plan INTO wa_invoicing_plan.
    lws_cnt = sy-tabix.
    CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
    input = lws_cnt
    IMPORTING
    output = lws_cnt .
    CONCATENATE 'FPLT-AFDAT(' lws_cnt ')' INTO lws_field.
    CONCATENATE wa_invoicing_plan-date+6(2)
    wa_invoicing_plan-date+4(2)
    wa_invoicing_plan-date+0(4) INTO lws_date
    SEPARATED BY '.'.
    PERFORM bdc_field USING lws_field lws_date.
    CONCATENATE 'FPLT-FPROZ(' lws_cnt ')' INTO lws_field.
    lws_perct = wa_invoicing_plan-percentage.
    CONDENSE lws_perct.
    PERFORM bdc_field USING lws_field lws_perct.
    ENDLOOP.
    While calling the transaction give like this:
    DATA: opt TYPE ctu_params.
    opt-dismode = 'N'.
    opt-updmode = 'A'.
    opt-defsize = 'X'.
    CALL TRANSACTION tcode
    USING i_bdcdata OPTIONS FROM opt MESSAGES INTO i_messages.
    LOOP AT i_messages.
    ENDLOOP.
    9. In call transaction and session method which method is prefered one?
    Ans. it depends on data if data is small then go for call transaction method.
    10. why can't we use call transaction method to upload large amount of data?
    Ans.there are chances of many errors.
    11.what is the use of standard text in sap scripts, why can't we hard code the same information in form itself?
    Ans.Assume ur company has stored some text which will printed on sapscript based on certain conditions and not taken thru driver program .
    For eg .for a plant 1000
    You have to print 'Plant is 1000 and stock is 1000'.
    for plant 1010
    You have to print 'Plant is 4000 and stock is 3000'.
    Then you will create a standard text thru SO10 create a text name and id would be ST and language as EN .
    AND YOU PLace the text You have to print 'Plant is 1000 and stock is 1000'.
    and this will create one standard text and another standard text for another .
    then in the sapscript you will check the plant
    use the command in the sapscript and write
    Include text name 'zzz' id ST lanuage en.
    When you execute
    Sapscript will read the include and bring the text from SO10 and print on the screen .
    Check T-Code NACE

    12.what are user exits and how can we create them?
    User exits -> They are the provisions given by the sap standard program to add some extra functionality to their program .
    Which will be present till there is any version change .
    1. User exits were nothing but
    subroutines
    FORM/PERFORM
    called from standard programs.
    2. The FORM defintion was placed inside
    an empty include file.
    3. So It was called EVERYTIME.
    and we need to MODIFY/REPAIR the
    standard include .
    USER EXITS
    1. Introduction:
    User exits (Function module exits) are exits developed by SAP.
    The exit is implementerd as a call to a functionmodule.
    The code for the function module is writeen by the developer.
    You are not writing the code directly in the function module,
    but in the include that is implemented in the function module.
    The naming standard of function modules for functionmodule exits is:
    EXIT_<program name><3 digit suffix>
    The call to a functionmodule exit is implemented as:
    CALL CUSTOMER.-FUNCTION <3 digit suffix>

    13. can we modify the sap provided code?
    Ans. Yes,but you need to have access key and i thing you need to have permission also.
    14. what are oss notes?
    ans.SAP provides support in the form of Notes also and this is called OSS. Can check the link Sree provided.
    Just for an example if you face any error in your system. Then there is error number associated with the error. Then you can search for the OSS not for the error number, and the note will give you possible solution to your problem.
    You do have notes for any details for every thng and any thing related to SAP.
    ans.YES! It is Online Suppor System from SAP. It is official.
    Search in http://service.sap.com support portal link with keywork 'OSS' / 'OSS User Guide' to get more info and 'how to' guides.
    OSS (online support system) .You can get this support from WWW.SAP.COM site..SAP will issue OSS userid and password to the customers with each licence to their packages..Here you will get all suppost packages information and how to use the things..These kind of info you will get it..Ask your Project customer about this id.. OSS1 is the transaction code to check the oss notes from SAP...
    15. what are the different types of performance techniques?
    Ans. Use se30--- simply gives you an over view of the time spent on the application processing against the time spend selecting from the database.
         use sto5 _SQL trace tool ---Overview of exactly how the prog is hitting against the database and shows you the individual SQL statements used with which index was used.
    16. can we do modifications on output of ALV reports, how?
    ans.
    17. what are the classes that are used in ALV reporting?
    ans.Check out this tutorial
    An Easy Reference for ALV Grid Control.pdf

    hi,
    Inserting or Changing Lines
    To insert lines into a database table regardless of whether there is already a line in the table with the same primary key, use the following:
    MODIFY <target> <lines>.
    If the database table contains no line with the same primary key as the line to be inserted, MODIFY works like INSERT, that is, the line is added.
    If the database already contains a line with the same primary key as the line to be inserted, MODIFY works like UPDATE, that is, the line is changed.
    For performance reasons, you should use MODIFY only if you cannot distinguish between these two options in your ABAP program.
    You can add or change one or more lines <lines> in a database table <target>. You can only insert or change lines in an ABAP Dictionary view if it only contains fields from one table, and its maintenance status is defined as Read and change. You may specify the database table <target> either statically or dynamically
    To insert or change a single line in a database table, use the following:
    MODIFY <target> FROM <wa> .
    To insert or change several lines in a database table, use the following:
    MODIFY <target> FROM TABLE <itab> .
    To overwrite a single line in a database table with the contents of a work area, use the following:
    UPDATE <target> FROM <wa> .
    To overwrite several lines in a database table with the contents of an internal table, use the following:
    UPDATE <target> FROM TABLE <itab> .
    INDEX TABLE
    For creating a generic table type with index access.
    ANY TABLE
    For creating a fully-generic table type.
    Data types defined using generic types can currently only be used for field symbols and for interface parameters in procedures . The generic type INDEX TABLE includes standard tables and sorted tables. These are the two table types for which index access is allowed. You cannot pass hashed tables to field symbols or interface parameters defined in this way. The generic type ANY TABLE can represent any table. You can pass tables of all three types to field symbols and interface parameters defined in this way. However, these field symbols and parameters will then only allow operations that are possible for all tables, that is, index operations are not allowed.
    Fully-Specified Table Types
    STANDARD TABLE or TABLE
    For creating standard tables.
    SORTED TABLE
    For creating sorted tables.
    HASHED TABLE
    For creating hashed tables.
    Fully-specified table types determine how the system will access the entries in the table in key operations. It uses a linear search for standard tables, a binary search for sorted tables, and a search using a hash algorithm for hashed tables.

    You can do as suggested already and use interface nodes and cross component mapping; but that is all really not necessary.  It creates a situation where you calling application is too dependent upon the freely programmed input help.  You want to try to avoid the situation where the calling application needs code or mappings to communicate with the input help.
    That is easy to do because the framework passes all the information you need into the freely programmed input help via the value_help_listener object. 
    Part of the Freeley Programmed Input Help Component should be the component interface IWD_VALUE_HELP.  This comes with a component controller method called SET_VALUE_HELP_LISTENER.  This allows your freely programmed value help to capture this object called listener of type IF_WD_VALUE_HELP_LISTENER. I generally just store it awa into a component controller attribute.
    With this listerner object you have direct access to the context attribute in the calling component. You can query information about the calling UI element and of course set values directly back into it.  The listener is a hugely helpful object and should be the way you interact with the calling component whenever possible.  Here is small example:
      set single attribute
      wd_this->value_help_listener->f4_context_element->set_attribute(
      exporting
        name = wd_this->value_help_listener->f4_attribute_info-name
        value = l_time
