Query on select stmt

hi,
below is the extraction logic
1.     Select all invoice documents from Table VBRK where Sales Organization VBRK-VKORG, Distribution Channel VBRK- VTWEG and Division VBRK-SPART matches to Sales Organization, Distribution Channel and Division specified in the selection parameters and SD Document Catergory VBRK- VBTYP <> N u2013 Invoice Cancellation type S1 and S2.
2.     Select all invoice documents from the above where all Sold-to party/Ship-to party customers VBRK-KUNAG and payer customers VBRK-KUNRG matches to Sold-to party/Ship-to party and payer specified in the selection parameters
how to write the select stmts for the abluve logic??.
thank you in advance.

Hi.
I will lock this thread. This is not a question that should be discussed in this forum. Your specification is so close to real code that even without any ABAP knowledge a look into some demo programs and the online help for 'SELECT' will solve it.
As Martin said: If you tried it and have any particular problems then we can discuss them here.
Best regards,

  • Count (*)  for select stmt take more time than  execute a that sql stmt

    HI
    count (*) for select stmt take more time than execute a that sql stmt
    executing particular select stmt take 2.47 mins but select stmt is using the /*+parallel*/ (sql optimer) in that sql  command for faster execute .
    but if i tried to find out total number of rows in that query it takes more time ..
    almost 2.30 hrs still running to find count(col)
    please help me to get count of row faster.
    thanks in advance...

    thanks in advance...That may be because your client is displaying only the first few records when you are running the "SELECT *". But when you run "COUNT(*)", the whole records has to be counted.
    As already mentined please read teh FAQ to post tuning questions.

  • How to convert update,delete statement into select stmt

    Hi all,
         I have a field called dml_stmt, i am getting the dml statement has input from the user.
         My requirement is, if user is giving "update set col_name = 'xyz' from table_name where codition = 'aa'", before updating the table, i need to get old values from the table and put it in the audit table
         For that,i need to convert those update statement into select stmt and need to execute the query to get the data and then i will put it in the audit table..
         can anyone guide how to convert the update or delete stmt into select(need to write in pl/sql)
    Please do needfull things ......
    Regards,
    Jame

    Maybe I'm missing something, but why would auditing help here? It sounds like the user wants to know the prior values of the data, not the SQL UPDATE statement that was issued. Auditing would tell you that a table was updated, fine-grained auditing would tell you what the UPDATE statement was, but you'd need something else to capture the state of the data prior to the update.
    Depending on why putting triggers on every table was discounted, you may also want to take a look at using Workspace Manager or Total Recall (in 11g) to track a history of data changes. But triggers would be the common solution to this sort of problem.

  • RE: Using BAPI in place of select stmt..

    Hi Experts,
    We alway use Select stmt to fetch the datas and display it, so is there any way to use available BAPI's  to select data and display the resultant output?if so can you given one simple example...

    1. Did you ever re-visited your queries
    Total Questions:  32 (30 unresolved) 
    I will suggest to close them by rewarding/answering with your solutions, if they are solved.
    2. Seeing your queries I dont think, you try to search the forum before posting a query. Start using it from today.
    3. Read rules of engagements before posting queries.
    Now for this one, if you search for BAPIs, their usage and their documentation you can understand this one by yourself.

  • Select stmt issue, performance tuning.

    Hi Group,
    I have a question.
    There is a select stmt which is using inner join, and its taking good amoutn of time to get executed. I was told to tune the performance of that query. And my TL suggested me to use ranges in that select stmt, like the sign, option, low, high.
    Could you please help me out on this issue? Urgent.
    Thank you in advance.
    Regards,
    P. Varun Kumar.

    They are suggesting to use ranges rather than For all entries.
    Here is the query:

  • How to get all rows that are returned in inner sub query of select statemen

    If a sub query in select statement returns more than one row than how to get all those returned rows in the final
    output of the query .It will be all right if all column's value repeat and that multiple output of inner query comes
    in another column .
    How to get that ?

    As Frank said, you likely want a join, and likely an outer join to replicate the select in the projection. Something like:
    SELECT id,stat, section, USER_ID concerned_person
    FROM table_all,
      left join table2
        on room_id = sectoion and
           sur_role = 'r001'
    WHERE section IN (SELECT code
                      FROM t_area
                      WHERE dept= 'p002')An alternative, depending on where and how you are using the statement would be something like:
    SQL> WITH t AS (
      2    select 1 id from dual union all
      3    select 2 id from dual),
      4  t1 as (
      5    select 1 id, 'One' descr from dual union all

  • Need of SQL query in selecting distinct values from two tables

    hi,
    I need a query for selecting distinct values from two tables with one condition.
    for eg:
    there are two tables a & b.
    in table a there are values like age,sex,name,empno and in table b valuses are such as age,salary,DOJ,empno.
    here what i need is with the help of empno as unique field,i need to select distinct values from two tables (ie) except age.
    can anybody please help me.
    Thanks in advance,

    Not sure what you mean either, but perhaps this will start a dialog:

  • The parameter name [...] in the query's selection criteria does not match..

    Hi all,
    I'm trying to pratice EJB 3 (which I learnt at school), with JSF and JPA, but i'm really stuck with that error :
    Exception [TOPLINK-6094] (Oracle TopLink Essentials - 2.0 (Build b41-beta2 (03/30/2007))): oracle.toplink.essentials.exceptions.QueryException
    Exception Description: The parameter name [departmentID] in the query's selection criteria does not match any parameter name defined in the query.
    Query: ReadAllQuery(oracle.datamodel.Employees)
    I will try to explain clearly what i'm trying to do :
    In fact, i'm following that tutorial :
    http://www.oracle.com/technology/obe/obe1013jdev/10131/ejb_and_jpa/master-detail_pagewith_ejb.htm
    But, as i didn't have any oracle database, but had a mysql one on my machine, i decided to use that DB instead of the the oracle DB... So i created a set of example data (to replace the oracle example set) ...so i created the tables EMPLOYEE, and DEPARTMENT... with the correct relations (FK) and PK)
    All was ok, i choose my "mysql-connector" (jdbc) instead of the oracle jdbc connector... so i could follow the tutorial.
    My problem appears at the step 12 (of "Creating a Master-Detail JavaServer Faces Page"), when i run the file deptEmployees.jspx.
    The information of the first departement displays correctly :
    departmentID 1
    departmentName ... etc
    but it can't display the employees belonging to that department !
    the error is :
    JBO-29000: Exception Description: The parameter name [departmentID] in the query's selection criteria does not match any parameter name defined in the query. Query: ReadAllQuery(oracle.datamodel.Employees)
    I think i understand what is the problem... I think that the query in charge of gathering the data of a specific departement need a parameter, but couldn't find it. But i don't know why :-/ I have tried many things and read the topics talking about that error... but it didn't solved the problem. I don't know anymore where to investigate.
    I have created a Zip file of my work (it's an EJB/JSF Application.. with jdev 10.1.3.3.0)
    (available here : http://dl.free.fr/mQ5esdQuS/EJB_appli.zip)
    I would be glad if someone could take few minutes to help me.
    Thank you in advance,
    Thomas B (student)

    Hello,
    This is a common mistake. Java string comparisons in TopLink are case sensitive by default, and since column names are uppercase when defaulted, TopLink cannot find the "departmentID" column name. In this case, Departments ID column defaults to "DEPARTMENTID" as required by the JPA specification.
    Either change Departments id annotation to     @Id
        @Column(name="departmentID", nullable = false)
        private Integer departmentID;or change Employees' ManytoOne annotation to:
        @ManyToOne
        @JoinColumn(name = "departmentID", referencedColumnName = "DEPARTMENTID")
        private Departments departments;Best Regards,
    Chris

  • Impact of selecting "Removing Query from Selection List" in 2 channels.

    HI All ,
    I have customized a query in one channel (My Agreements and Contract Documents query in Master Agreements List channel) and have removed the standard query from the channel by checking the  "Remove Query from Selection List" and introduced my custom query in that query group .
    But  it resulted in break in chain for  "Master Agreements" link in "Contracts To Do List" channel as the link was pointing to standard  "My Agreements and Contract Documents" query and is displaying "The query can not be executed. Contact your system administrator" when ever I click on that.
    Any pointers on how to overcome above scenario wud be gr8!
    Regards,
    Uday

    Hi Uday,
    In order for To Do List channel to work, the query definition should be in the Master Agreement List query group. Do you still want the standard query in the To Do List? If so, you would have to leave it on the Query Group as To Do list is pointing to it. May be change the display name of the query so you can differentiate between the 2 queries. The other option is change the To Do channel to point to the custom query.
    Regards,
    Vikram

  • Use of Select stmts with Update stmts

    Hi,
    I want to execute the following update stmt...
    UPDATE Test1_tab a
    SET a.invpln_seq_no = (SELECT b.seq_no
    FROM Test2_tab b
    WHERE b.contract_id = a.contract_id
    AND b.date_from = a.period_from_date)
    WHERE a.invpln_seq_no != (SELECT b.seq_no
    FROM Test2_tab b
    WHERE b.contract_id = a.contract_id
    AND b.date_from = a.period_from_date)
    Here the problem is I have used 'SELECT b.seq_no FROM Test2_tab b WHERE b.contract_id = a.contract_id AND b.date_from = a.period_from_date' twice, one in the SET clause and the other one in WHERE clause...But it is the same SELECT stmt...So this same Select stmt runs twice when I run the whole update stmt I guess. Is there a way to do the above update, where it runs the SELECT stmt only once...
    Any input is highly appreciated...
    Thanks And Best Regards,
    /Dinesh...

    Then you can use Merge statement instead.
    try this
    merge into test1_tab t1
    using
    (SELECT a.rowid,b.seq_no SEQ_DEST
    FROM test1_tab a,test2_tab b
    WHERE b.contract_id = a.contract_id
    AND  b.date_from = a.period_from_date
    AND a.invpln_seq_no != b.seq_no) t2
    ON (t1.rowid=t2.rowid)
    WHEN MATCHED THEN
    UPDATE SET t1.invpln_seq_no=t2.seq_destor if you are sure that sno is a unique key with out any duplicates and if you are going to perform one time manual update then you can use an undocumented hint /*+ bypass_ujvc */ to do this.
    *DO NOT include this code if you are about to add it in a production procedure or a function
    UPDATE /*+ bypass_ujvc */ (SELECT a.invpln_seq_no SEQ_SRC,b.seq_no SEQ_DEST FROM test1_tab a,test2_tab  b
    WHERE b.contract_id = a.contract_id
    AND  b.date_from = a.period_from_date
    AND a.invpln_seq_no != b.seq_no)
    SET SEQ_SRC = SEQ_DESTRegards,

  • Reg different kinds of select stmts

    Hi All,
    Hope all are doing gud,
    cud any tell me different kinds of select stmts ????
    regards,
    abc xyz

    hi,
    SELECT
    Basic form
    SELECT result [target] FROM source [where] [GROUP BY fields] [ORDER BY order].
    Effect
    Retrieves an extract and/or a set of data from a database table or view (see Relational database ). SELECT belongs to the OPEN SQL command set.
    Each SELECT command consists of a series of clauses specifying different tasks:
    The SELECT result clause specifies
    whether the result of the selection is a table or a single record,
    which columns the result is meant to have and
    whether the result is allowed to include identical lines.
    The INTO target clause specifies the target area into which the selected data is to be read. If the target area is an internal table, the INTO clause specifies
    whether the selected data is to overwrite the contents of the internal table or
    whether the selected data is to be appended to the contents and
    whether the selected data is to be placed in the internal table all at once or in several packets.
    The INTO clause can also follow the FROM clause.
    You can omit the INTO clause. The system then makes the data available in the table work area (see TABLES ) dbtab . If the SELECT clause includes a "*", the command is processed like the identical SELECT * INTO dbtab FROM dbtab statement. If the SELECT clause contains a list a1 ... an , the command is executed like SELECT a1 ... an INTO CORRESPONDING FIELDS OF dbtab FROM dbtab .
    If the result of the selection is meant to be a table, the data is usually (for further information, see INTO -Klausel ) read line by line within a processing loop introduced by SELECT and concluded by ENDSELECT . For each line read, the processing passes through the loop once. If the result of the selection is meant to be a single record, the closing ENDSELECT is omitted.
    The FROM source clause the source (database table or view ) from which the data is to be selected. It also determines
    the type of client handling,
    the behavior for buffered tables and
    the maximum number of lines to be read.
    The WHERE where clause specifies the conditions which the result of the selection must satisfy. It thus determines the lines of the result table. Normally - i.e. unless a client field is specified in the WHERE clause - only data of the current client is selected. If you want to select across other clients, the FROM clause must include the addition ... CLIENT SPECIFIED .
    The GROUP-BY fields clause combines groups of lines together into single lines. A group is a set of lines which contain the same value for every database field in the GROUP BY clause.
    The ORDER-BY order clause stipulates how the lines of the result table are to be ordered.
    Each time the SELECT statement is executed, the system field SY-DBCNT contains the number of lines read so far. After ENDSELECT , SY-DBCNT contains the total number of lines read.
    The return code value is set as follows:
    SY-SUBRC = 0 At least one line was read.
    SY_SUBRC = 4 No lines were read.
    SY-SUBRC = 8 The search key was not fully qualified.
    (nur bei SELECT SINGLE ). The returned single record is any line of the solution set.
    Example
    Output the passenger list for the Lufthansa flight 0400 on 28.02.1995:
    TABLES SBOOK.
    SELECT * FROM SBOOK
      WHERE
        CARRID   = 'LH '      AND
        CONNID   = '0400'     AND
        FLDATE   = '19950228'
      ORDER BY PRIMARY KEY.
      WRITE: / SBOOK-BOOKID, SBOOK-CUSTOMID,   SBOOK-CUSTTYPE,
               SBOOK-SMOKER, SBOOK-LUGGWEIGHT, SBOOK-WUNIT,
               SBOOK-INVOICE.
    ENDSELECT.
    Performance
    In client/server environments, storing database tables in local buffers (see SAP buffering ) can save considerable amounts of time because the time required to make an access via the network is much more than that needed to access a locally buffered table.
    Notes
    A SELECT command on a table for which SAP buffering is defined in the ABAP/4 Dictionary is normally satisfied from the SAP buffer by bypassing the database. This does not apply with
    - <b>SELECT SINGLE FOR UPDATE
    - SELECT DISTINCT in the SELECT clause ,
    - BYPASSING BUFFER in the FROM clause ,
    - ORDER BY f1 ... fn in the ORDER-BY clause ,
    - aggregate functions in the SELECT clause ,
    - when using IS [NOT] NULL WHERE condition ,</b>
    or if the generic key part is not qualified in the WHERE-Bedingung for a generically buffered table.
    Authorization checks are not supported by the SELECT statement, so you must program these yourself.
    In dialog systems, the database system locking mechanism cannot always guarantee to synchronize the simultaneous access of several users to the same dataset. In many cases, it is therefore advisable to use the SAP locking mechanism .
    Changes to data in a database are only finalized after a database commit (see LUW ). Prior to this, any database update can be reversed by a database rollback (see Programming transactions ). At the lowest isolation level (see the section on the "uncommitted read" under Locking mechanism ), this can result in the dataset selected by the SELECT command not really being written to the database. While a program is selecting data, a second program can add, change or delete lines at the same time. Then, the changes made by the second program are reversed by rolling back the database system. The selection of the first program thus reflects only a very temporary state of the database. If such "phantom data" is not acceptable for a program, you must either use the SAP locking mechanism or at least set the isolation level of the database system to "committed read" (see Locking mechanism ).
    In a SELECT-ENDSELECT loop, the CONTINUE statement terminates the current loop pass prematurely and starts the next.
    If one of the statements in a SELECT ... ENDSELECT loop results in a database commit, the cursor belonging to the SELECT ... ENDSELECT loop is lost and the processing terminates with a runtime error. Since each screen change automatically generates a database commit, statements such as CALL SCREEN , CALL DIALOG , CALL TRANSACTION or MESSAGE are not allowed within a SELECT ... ENDSELECT loop.

    SELECT clause
    Variants
    1. <b>SELECT [SINGLE [FOR UPDATE] | DISTINCT] *
    2. SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... sn
    3. SELECT [SINGLE [FOR UPDATE] | DISTINCT] (itab)</b> Effect
    The result of a SELECT statement is itself a table . The SELECT clause describes which columns this table is supposed to have.
    In addition, you can use the optional addition SINGLE or DISTINCT if you want only certain lines of the solution set to be visible for the calling program:
    SINGLE The result of the selection is a single record . If this record cannot be uniquely identified, the first line of the solution set is selected. The addition FOR UPDATE protects the selected record against parallel changes by other transactions until the next database commit occurs (see LUW and Database locking ). If the database system detects a deadlock, the result is a runtime error.
    DISTINCT Any lines which occur more than once are automatically removed from the selected dataset.
    Note
    To ensure that a record is uniquely determined, you can fully qualify all fields of the primary key by linking them together with AND in the WHERE condition.
    Note
    Performance
    The additions SINGLE FOR UPDATE and DISTINCT exclude the use of SAP buffering .
    The addition DISTINCT requires sorting on the database server and should therefore only be specified if duplicates are likely to occur.
    Variant 1
    SELECT [SINGLE [FOR UPDATE] | DISTINCT] *
    Effect
    In the result set, the columns correspond exactly in terms of order, ABAP/4 Dictionary type and length to the fields of the database table (or view ) specified in the FROM clause .
    Example
    Output all flight connections from Frankfurt to New York:
    TABLES SPFLI.
    SELECT * FROM SPFLI
             WHERE
               CITYFROM = 'FRANKFURT' AND
               CITYTO   = 'NEW YORK'.
      WRITE: / SPFLI-CARRID, SPFLI-CONNID.
    ENDSELECT.
    Example
    Output all free seats on the Lufthansa flight 0400 on 28.02.1995:
    TABLES SFLIGHT.
    DATA   SEATSFREE TYPE I.
    SELECT SINGLE * FROM SFLIGHT
                    WHERE
                      CARRID   = 'LH '      AND
                      CONNID   = '0400'     AND
                      FLDATE   = '19950228'.
    SEATSFREE = SFLIGHT-SEATSMAX - SFLIGHT-SEATSOCC.
    WRITE: / SFLIGHT-CARRID, SFLIGHT-CONNID,
             SFLIGHT-FLDATE, SEATSFREE.
    Variant 2
    SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... sn
    Effect
    The order, ABAP/4 Dictionary type and length of the columns of the result set are explicitly defined by the list s1 ... sn . Each si has the form
    ai or ai AS bi .
    Here, ai stands either for
    a field f of the database table or
    a aggregate print.
    bi is an alternative name for the i-th column of the result set.
    When using INTO CORRESPONDING FIELDS OF wa in the INTO clause , you can specify an alternative column name to assign a column of the result set uniquely to a column of the target area.
    An aggregate print uses an aggregate function to group together data from one or all columns of the database table. Aggregate prints consist of three or four components:
    An aggregate function immediately followed by an opening parenthesis DISTINCT (optional) The database field f A closing parenthesis
    All components of a print must be separated by at least one blank.
    The following aggregate functions are available:
    MAX Returns the greatest value in the column determined by the database field f for the selected lines. Specifying DISTINCT does not change the result. NULL values are ignored unless all values in a column are NULL values. In this case, the result is NULL .
    MIN Returns the smallest value in the column determined by the database field f for the selected lines. Specifying DISTINCT does not change the result. NULL values are ignored unless all values in a column are NULL values. In this case, the result is NULL .
    AVG Returns the average value in the column determined by the database field f for the selected lines. AVG can only apply to a numeric field. NULL values are ignored unless all values in a column are NULL values. In this case, the result is NULL .
    SUM Returns the sum of all values in the column determined by the database field f for the selected lines. SUM can only apply to a numeric field. NULL values are ignored unless all values in a column are NULL values. In this case, the result is NULL .
    COUNT Returns the number of different values in the column determined by the database field f for the selected lines. Specifying DISTINCT is obligatory here. NULL values are ignored unless all values in a column are NULL values. In this case, the result is 0
    COUNT( * ) Returns the number of selected lines. If the SELECT command contains a GROUP BY clause , it returns the number of lines for each group. The form COUNT(*) is also allowed.
    If ai is a field f , MAX( f ) , MIN( f ) or SUM( f ) , the corresponding column of the result set has the same ABAP/4 Dictionary format as f . With COUNT( f ) or COUNT( * ) , the column has the type INT4 , with AVG( f ) the type FLTP .
    If you specify aggregate functions together with one or more database fields in a SELECT clause, all database fields not used in one of the aggregate functions must be listed in the GROUP-BY clause . Here, the result of the selection is a table.
    If only aggregate functions occur in the SELECT clause, the result of the selection is a single record. Here, the SELECT command is not followed later by an ENDSELECT .
    Notes
    This variant is not available for pooled tables and cluster tables .
    If the SELECT clause contains a database field of type LCHAR or LRAW , you must specify the appropriate length field immediately before.
    Notes
    Performance
    Specifying aggregate functions excludes the use of SAP buffering .
    Since many database systems do not manage the number of table lines and therefore have to retrieve this at some cost, the function COUNT( * ) is not suitable for checking whether a table contains a line or not. To do this, it is best to use SELECT SINGLE f ... for any table field f .
    If you only want to select certain columns of a database table, you are recommended to specify a list of fields in the SELECT clause or to use a View .
    Examples
    Output all flight destinations for Lufthansa flights from Frankfurt:
    TABLES SPFLI.
    DATA   TARGET LIKE SPFLI-CITYTO.
    SELECT DISTINCT CITYTO
           INTO TARGET FROM SPFLI
           WHERE
             CARRID   = 'LH '       AND
             CITYFROM = 'FRANKFURT'.
      WRITE: / TARGET.
    ENDSELECT.
    Output the number of airline carriers which fly to New York:
    TABLES SPFLI.
    DATA   COUNT TYPE I.
    SELECT COUNT( DISTINCT CARRID )
           INTO COUNT FROM SPFLI
           WHERE
             CITYTO = 'NEW YORK'.
    WRITE: / COUNT.
    Output the number of passengers, the total weight and the average weight of luggage for all Lufthansa flights on 28.02.1995:
    TABLES SBOOK.
    DATA:  COUNT TYPE I, SUM TYPE P DECIMALS 2, AVG TYPE F.
    DATA:  CONNID LIKE SBOOK-CONNID.
    SELECT CONNID COUNT( * ) SUM( LUGGWEIGHT ) AVG( LUGGWEIGHT )
           INTO (CONNID, COUNT, SUM, AVG)
           FROM SBOOK
           WHERE
             CARRID   = 'LH '      AND
             FLDATE   = '19950228'
           GROUP BY CONNID.
      WRITE: / CONNID, COUNT, SUM, AVG.
    ENDSELECT.
    Variant 3
    SELECT [SINGLE [FOR UPDATE] | DISTINCT] (itab)
    Effect
    Works like SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... sn if the internal table itab contains the list s1 ... sn as ABAP/4 source code, and like SELECT [SINGLE [FOR UPDATE] | DISTINCT] * , if itab is empty. The internal table itab can only have one field which must be of type C and cannot be more than 72 characters long. itab must appear in parentheses and there should be no blanks between the parentheses and the table name.
    Note
    With this variant, the same restrictions apply as for SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... sn .
    Example
    Output all Lufthansa flight routes:
    TABLES: SPFLI.
    DATA:   FTAB(72) OCCURS 5 WITH HEADER LINE.
    REFRESH FTAB.
    FTAB = 'CITYFROM'. APPEND FTAB.
    FTAB = 'CITYTO'.   APPEND FTAB.
    SELECT DISTINCT (FTAB)
           INTO CORRESPONDING FIELDS OF SPFLI
           FROM SPFLI
           WHERE
             CARRID   = 'LH'.
      WRITE: / SPFLI-CITYFROM, SPFLI-CITYTO.
    ENDSELECT.

  • Problem in Select stmt in loop

    Hi all,
    Pls provide your suggestions for the following code.
    LOOP at ITAB.
    select * from zxyz into corresponding fields of table ITAB_FINAL
    where fromdate eq date1
              todate eq date2
              MATNR eq ITAB-matnr.
    ENDLOOP.
    My question is that for a particular entry in itab , select stmt is executed and some 5 to 6 line item is selected into itab_final. Now in second loop , again select stmt is executed and again some line item will be selected , BUT will this selection will replace the earlier entry in ITAB_FINAL OR the entry in SUCCESSIVE loop will be APPENDED ?
    Please suggest your valuable suggestion on this problem
    Thanks in advance,
    Regards,
    Vivek

    Hi,
    There is no need to loop if you are using FOR ALL ENTRIES
    select * from zxyz into corresponding fields of table ITAB_FINAL
    for all entries in itab
    where matnr eq itab-matnr
    and fromdate eq date1
    and todate eq date2.
