How to delete the records from database table without using work area

Hi all,
The purpose of the down program is to delete the entire contents from all the tables. The deletion of the table should be in sorted manner. Is there any other way to write the code more efficiently,
TABLES: ZFFMCTL_AP, ZFFMHDR_AP, ZFFM_CHANGE_LOG, ZFFMDTL_AR, ZFFMHDR_AR, ZFFMDTL_JV, ZFFMHDR_JV, ZFFMDTL_SKF,ZFFMHDR_SKF,ZFINVOICE_DETAIL, ZFFMMASTER, ZFFMLOGREAD_CLUS, ZFFMCTL.
DELETE ZFFMCTL_AP.
IF SY-SUBRC = 0.
DELETE ZFFMMHDR_AP.
IF SY-SUBRC = 0.
DELETE ZFFM_CHANGE_LOG.
IF SY-SUBRC = 0.
DELETE ZFFMDTL_AR.
IF SY-SUBRC = 0.
DELETE ZFFMHDR_AR.
IF SY-SUBRC = 0.
DELETE ZFFMDTL_JV.
IF SY-SUBRC = 0.
DELETE ZFFMHDR_JV.
IF SY-SUBRC = 0.
DELETE ZFFMDTL_SKF.
IF SY-SUBRC = 0.
DELETE ZFFMHDR_SKF.
IF SY-SUBRC = 0.
DELETE ZFINVOICE_DETAIL.
IF SY-SUBRC = 0.
DELETE ZFFMMASTER.
IF SY-SUBRC = 0.
DELETE ZFFMLOGREAD_CLUS.
IF SY-SUBRC = 0.
DELETE ZFFMCTL.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
ENDIF.
Waiting for response,
Thanks in advance

  • How to delete the records from custom table???

    My requirement is,
    I have a custom table, assume as ZABC, I have updated this by my custom program, This data having table can be extracted by BI etract program(Assume ZZZ). Here I am not writing any code for extracting data from table to BI extract program, That they will do by BI extract program. But I want to write the code for
    <b>Cleanup of Z table—delete records 30 days after the BI data extractor has run.</b>
    How this is possible suggest me any method having for these???
    Thanks Sanju

    Hell Sanjana,
    Ask your basis people to do the clean up after  30 days. If you want the clean up only to be done 30 days after BI extract has been done, then u need some sort of indicator to say that BI Extract has been done , like  flag and date in a custom table which will be set as soon as extract is done. Then based on that info u need to delete a the records.

  • Add a new record in database table without using table maintance generator

    Hi Expart ,
                  Plz. tell me how to add new record in database table without using table maintance ganerator ....give me one ex.
    Regards
    Bhabani

    Hi,
    The other way to safely handle the modification of tables is through is by programs that can be done with SE38 or SE80.
    To insert into database table we use INSERT statement :
    1. To insert a single line into a database table, use the following:
    INSERT INTO <target> VALUES <wa>.
    INSERT <target> FROM <wa>.
    2. To insert a several lines into a database table, use the following:
    INSERT <target> FROM TABLE <itaba>.
    Or even we can use MODIFY statementas this single statement is used to insert as well as update the records of database table.
    MODIFY <target> FROM <wa>.
    or MODIFY <target> FROM TABLE <itab>.
    thanx.

    Hi Naren,
    First get the index number of the IT_data table and store it in one variable whose declaration like this.
    data: tabix type sy-tabix.
    while reading the internal table it_data set the tabix variable.
    tabix = sy-tabix.
    Instead of  the above use below one.
    Delete it_data-objek
    Use the Below statement it will delete  the row from the internal table.
    Delete it_data-objek index tabix
    Thanks,

  • How to delete a record from BSEG table

    Dear Experts,
    How to delete a record from BSEG table.
    If there possible to delete some records from transparent table ?
    Please help.
    Regards,
    Tan

    Hi,
    Deleting a record from a standard table can be done only if table maintenance exists - Cehck tcode - SM30.  But it is not advisable to delete records, coz the records may be dependent on many other tables.  If u delete in a single place, there may be chance that inconsistency in the data happens and hence will affect ur financial statements.
    Pls. assign points, if useful

  • How to delete the data from partition table

    Hi all,
    Am very new to partition concepts in oracle..
    here my question is how to delete the data from partition table.
    is the below query will work ?
    delete from table1 partition (P_2008_1212)
    we have define range partition ...
    or help me how to delete the data from partition table.

    Oracle supports different structures for data and indexes. A table can be a hash table or index organised table. It can have B+tree index. It can have bitmap indexes. It can be partitioned. Etc.
    How the table implements its structure is a physical design consideration.
    Application code should only deal with the logical data structure. How that data structure is physically implemented has no bearing on application. Does your application need to know what the indexes are and the names of the indexes,in order to use a table? Obviously not. So why then does your application need to know that the table is partitioned?
    When your application code starts referring directly to physical partitions, it needs to know HOW the table is partitioned. It needs to know WHAT partitions to use. It needs to know the names of the partitions. Etc.
    And why? All this means is increased complexity in application code as this code now needs to know and understand the physical data structure. This app code is now more complex, has more moving parts, will have more bugs, and will be more complex to maintain.
    Oracle can take an app SQL and it can determine (based on the predicates of the SQL), which partitions to use and not use for executing that SQL. All done totally transparently. The app does not need to know that the table is even partitioned.
    This is a crucial concept to understand and get right.

    You mean when you click on the hyperlink you want that row to disappear from the page, but not delete the row from the database until a commit/submit button is pressed?
    Personally, I think I'd prefer that you have a delete checkbox next to every row and NOT remove them from the display if I was a user. You give your users a chance to change their mind about their choice, and when they're done they can see exactly which rows will be deleted before they commit.
    You know your problem, of course, so you might have a good reason for designing it this way. But I'd prefer not removing them from the display. JMO - MOD

  • How to delete a row from database table in facade client

    Hi all,
    I followed the tutorial in creating a persistence entity from database table, then a session facade. Then I followed the tutorial to create a sample client to test the model. In the session facade, I could use persistEntity method to insert a record to the database. I am just thinking of an extension to the tutorial, i.e., being able to delete the record too. So I created a new method removeEntity in the session facade
    public void removeEntity(Object entity) {
    entity=em.merge(entity);
    em.remove(entity);
    em.flush();
    and called it in the sample client. It was executed without any error, but the record in the table still exists.
    I tried to look around for a solution, but I did not find one. Would anybody here please help out? Many thanks in advance!

    Application code should only deal with the logical data structure. How that data structure is physically implemented has no bearing on application. Does your application need to know what the indexes are and the names of the indexes,in order to use a table? Obviously not. So why then does your application need to know that the table is partitioned?
    When your application code starts referring directly to physical partitions, it needs to know HOW the table is partitioned. It needs to know WHAT partitions to use. It needs to know the names of the partitions. Etc.
    And why? All this means is increased complexity in application code as this code now needs to know and understand the physical data structure. This app code is now more complex, has more moving parts, will have more bugs, and will be more complex to maintain.
    Oracle can take an app SQL and it can determine (based on the predicates of the SQL), which partitions to use and not use for executing that SQL. All done totally transparently. The app does not need to know that the table is even partitioned.
    This is a crucial concept to understand and get right.

  • How to delete the entries from NAST table

    Hi,
    Please help me out by providing any function module that delete's the entries from hte NAST table.
    Regards,
    Kiran.L

    REPORT ZSCD_TEST13.
    delete from nast where VSTAT = '1'.
    =====
    If you see the FM : NAST_DELETE_OBJECT, its only useful when NACHA = 7 (i.e. message transmission medium = Simple Mail)
    For others its not useful.
    We had similar issue few days back and after long RnD, we straightaway deleted the entries using the Zprogram.
