Its urgent send with coding example is better

Hi

            percent(1) TYPE p DECIMALS 0.
DATA sflight_tab TYPE TABLE OF sflight.
FIELD-SYMBOLS <sflight> TYPE sflight.
SELECT *
       FROM sflight
       INTO TABLE sflight_tab
       WHERE carrid = p_carrid AND
             fldate = sy-datum.
IF sy-subrc = 0.
  LOOP AT sflight_tab ASSIGNING <sflight>.
    <sflight>-price =
      <sflight>-price * ( 1 - percent / 100 ).
  ENDLOOP.

    Hi,
    loop at internal table.
    modify <Z- table > from values < internal table Workarea>.
    if sy-subrc = 0.

  • Update databse from internal table statement not using index

    Hi Guys,
    We are updating a databse table from a file. The file has a couple of fields which have data different from what the database has (non-primary fields :). We upload the file data into an internal table and then update the database table from internal table. At a time, internal table is supposed to have 10,000 records. I did SQL trace and found that the update statement is not making use of the databse index.
    Should not the update statement here be using the table index (for primary key)?
    Regards,
    Munish

    ... as often there are recommendations in this forum which makes me wonder, how people overestimate their knowledge!!!
    Updates and Deletes do of course use indexes, as can be seen in the SQL Trace (use explain).
    Inserts don't use indexes, because in many databases inserts are just done somewhere, But also with the INSERT, the primary key is the constraint for the uniqueness condition, duplicate keys are not allowed.
    Coming to the original question, what is you actually coding for the update?
    What is the table, which fields are in the internal table and what are the indexes?

  • Update ztable from database table directly

    hi all,
    can u tell me the possible ways to update a ztable from database table directly.
    i mean is there anyway to update ztable whenever entry is created in database table .
    i dont want to update using insert,modify statements.
    points will be rewarded to all hlpful answers.

    A slightly dirty solution:
    Use SAP functions for reading from CDHEADER and CDPOS tables [with enough filters such that you extract minimum records possible] to read changes to MARA table fields since last run of your program. Use this information to update your ZTABLE. I would recommend having a table maintainance generator on ZTABLE. The actual update should be by a BDC by calling transaction SM30 for ZTABLE maintainance. Now the program may be set up as a batch job running 1ce an hour. You get updates to the extent of 1 hour latency.
    Alternatively, you may look if an opportunistic BADI / user Exit is there alongside MM01/02 transactions - assuming the latter are the only ones updating MARA. In this BADI you may write the code to update ZTABLE- again, look to do it by BDC call transaction sm30 to maintain ZTable. To lighten up the code -load on BADI you may simply raise a custom event and move on. You will configure a job that runs your program when that particular event is raised. This will need the 'burden' of figuring out the changes, though.
    An elegant way would be to fire a MATMAS fIDOC for every change to Material, capture that and turn back the changes to ZTABLE. This will facilitate the delta load.

  • Modify ztable from internal table

    Hi,
    I have a Ztable in which i have 4 diff fields....1 2 3 4
       and an internal table in whch i have same number of fields...
    Internal table :
        1 2 3 4
        a w x 9
        a w x 10
        a w x 11
        a w x 13
        a w x 12
    When I am using Modify it only appends last record into ztable as below:
    Ztable :  1 2 3 4
               a w x 12
    Internal table has 6 records and z table should be appended with 6 records too...
      if varid-report  = 'ZFINRR1001' and

         varid-VARIANT = 'WACHOVIA - ZBA'.

    Hi,
    You only get last record appended because your MODIFY statement uses t_data_new as a working area and not as a table.
    To append the content of your internal table, use the FROM TABLE option as below :
    MODIFY zv12_sweep FROM TABLE t_data_new.

  • Updating ztable from the table maintenance

    hi,
           I want to knw how and where to check , whether the records which user has entered in the table control of new entries screen exists in the ztable table or not . if the same record exists then that record should not go for saving it shd be deleted when it is detected that it exists in the ztable . can any one tell me how . where and what code to be written . so that the duplicate entries are deleted and others entries get appended in the database.
    thank you.

    Hi
    if you have declared some Primary key fields then by default when you enter the records in the Table maintenance using SM30 it will not allow duplicate records with the same key fields
    You can check the Table entries in SE16 Tcode
    go to Se16 enter table name execute and see the table records

  • Need to update Ztable from final internal table

    Hi,
    ITAB   = Final internal table has 9 fields : 1 2 3 4 5 6 7 8 9
    Ztable = Ztable has 6 fields ex : 1 3 4 6 7 8
    Structure of both Itab and Ztable are different.
    I have data in the Final Internal table and needs to update data into a ztable.
    If condition is true...
      Modify ztable from itab
    endif.
    Any suggestions how I can update Ztable from the INternal table
    Regards,
    Kittu

    Hello,
    First keep the loop to the final internal table then move all the records to the work area after moving to workarea then create another workarea for the Ztable then move only the field values which are there in Ztable then use modify keyword.
    example
    move:
    y_wa_final_itab-kdauf to y_wa_zhr_item-vbeln,
    y_wa_final_itab-kdpos to y_wa_zhr_item-posnr,
    y_wa_final_itab-receiptno to y_wa_zhr_item-receiptno
    modify zhr_item from y_wa_zhr_item

    Hi Matthew,
    I think there is no difference in database insert between OO and non-OO.
    The correct syntax according to ECC600 online documentation is
    [Inserting Several Lines|http://help.sap.com/saphelp_erp2005vp/helpdata/en/fc/eb3a6d358411d1829f0000e829fbfe/content.htm]
    To insert several lines into a database table, use the following:
    INSERT target FROM TABLE itab \[ACCEPTING DUPLICATE KEYS].
    This writes all lines of the internal table itabto the database table in one single operation. If one or more lines cannot be inserted because the database already contains a line with the same primary key, a runtime error occurs. You can prevent the runtime error occurring by using the addition ACCEPTING DUPLICATE KEYS.
    Whenever you want to insert more than one line into a database table, it is more efficient to work with an internal table than to insert the lines one by one.
    I think the syntax
    INSERT my_dbtable FROM TABLE gi_data.
    should work, your suggestion may lead to syntax error.
    Regards,
    Clemens

  • To get recent timestamp records from internal table

    hi all,
      i have one requirment
      i'm storing error messages in one table  while creating a sales order basing on timestamp
      which is of this format yyyy-mm-dd hh:mm:ss (random Number) 
      if i want to see the error messages left i'm getting all the error messages displayed
      for example i have created a sales order
    i got 10 errors displayed
    i have rectified 5 errors ... if i again display error messages the 10 errors + the 5 errors is getting displayed
    i want to display the 5 error messages only not the previous messages from internal table
    basing on timestamp current one has to displayed remaining has to deleted from internal table.

    I thought we used Sales Order Incompletion process for this....  but, if you're recreating the errors list every time you save with a create or change transaction then, at save, delete all rows in your error table for this document.   Then get your errors and update your db table from your current errors table.   From this viewpoint, the timestamp is not relevant.

    UPDATE dbtab FROM TABLE itab. or UPDATE (dbtabname) FROM TABLE itab.
    Effect
    Mass update of several lines in a database table.Here, the primary key for identifying the lines tobe updated and the values to be changed are taken from the lines of theinternal table itab. 
    The system field SY-DBCNT contains the number of updated lines,i.e. the number of lines in the internal table itab which havekey values corresponding to lines in the database table.
