对上面提到的几个term不是很明白（尤其是statistical table和ordinary table），其中structure应该不是表的类型。
请举例。

    I HAVE A SOURCE TABLE WITH 10 RECORDS AND TARGET TABLE 15 RECORDS. MY QUESTION IS USING WITH THE TABLE COMPARISON TRANSFORM .I WANT TO DELETE UNMATCHED RECORDS FROM THE TARGET TABLE ?? HOW IT IS ??

    Hi Kishore,
    First identify deleted records by selecting "Detect deleted rows from comparison table" feature in Table Comparison
    Then Use Map Operation with Input row type as "delete" and output row type as "delete" to delete records from target table.

  • At what level are the records pooled in COSS and COSP Tables

    Dear All,
    I have a question for you. i wold like to know what is the criteria that is taken into consideration while arriving at the totals in the COSS and COSP Tables.
    What are the fields that must be similar for some line items to be pooled and shown as a total record in COSS Or COSP Tables.
    For Ex: If i have two records in COEP table, what are the fields that must be equall for them to be shown as one Record in COSS or COSP table.
    Best Regards

    Criteria for pooling in COSS/COSP is the following:-
    Ledger
    Object number
    Fiscal Year
    Value Type
    Version
    Cost Element
    CO subkey
    Bus.Transaction

  • Dynamic Structures and Internal Tables

    Hi All,
    I am doing a report to create condition records based on the condition type and condition table. Assume the condition type as PR00 and it as condition table of 304,305,306.Each condition table as its own header and item fields.Based on the  condition table that the user specifies in the selection screen
    the header and item structures of my report should change dynamically and these should be moved  to the dynamic internal table that contains both header and item fields.Can anyone give an idea how to achieve it. Thanks in advance.
    Regards,
    Chakradhar.

    Hi All,
    Thanks for your replies.
    SPLIT i_string_line-input_str AT cl_abap_char_utilities=>horizontal_tab

              i_header_line-pltyp                                                                              
             i_header_line-waerk.    
    In the above syntax based on the condition table I selected on selection screen my flat file is as below.
    case 1: If condition table given is 304
    H    SalesOrganization    DistributionChannel    Customer
    I    Material    Releasestatus    Amount    Currency    ValidFrom    ValidTo

    H    SalesOrganization    DistributionChannel     PriceListType     DocumentCurrency
    I    Material    Releasestatus    Amount    Currency    ValidFrom    ValidTo
    In the above code i_string_line-input_str contains the following heading of fields based on the condition table we select in selection screen.when I want to split them into respective fields
    using INTO clause my structure should change dynamically.How can I achieve it and my entire program is in OOPS ALV.Thanks in Advance.

  • How to export Tables along with Data and also Tables without data

    Hi All,
    I have a strange situation here. I have a 2 existing schema's under one database. Now the client wants to have 4 more schema's to incorporate the new branches of his company.
    I want to know whether is it possible for me to run an expdp command by which i can have the data from the mentioned tables and only table structure of the remaining along with remaining database objects (procedure,functions,triggers,views,sequences etc).
    Since there are some 32 Master tables, whose data i need to capture in db dump in order to run the batch under new schema and the remaining tables will be populated with data from the new branch employees hence the need is for table’s structure only.

    Hi,
    you should run two different import comand.
    The first import with only metadata, just to recreate the structure.
    With the second import you will import data only for the tables you need.
    I think this is the simplier solution.

  • One to Many with multiple tables on One side and one table on Many side

    Sorry for the confusion in the title. Here is my question. In my program, I have 2 different tables which store 2 different type of entities. Each one of entities has a list of attachments which I stored in a common attachment table. There is a one-to-many relationship between entity tables and attachment table.
    ENTITY_ONE (
    ID
    NAME
    ENTITY_TWO (
    ID
    NAME
    ATTACHMENTS (
    ID
    ENTITY_ID
    ATTACHMENT_NAME
    ENTITY_ID in ATTACHMENTS table is used to link attachments to either entity one or entity two. All IDs are generated by one sequence. So they are always unique. My question is how I could map this relationship into EntityOne, EntityTwo and Attachment JAVA class?

    For EntityOne and EntityTwo you can just define a normal OneToMany mapping using the foreign key.
    Are you using JPA, or the TopLink API? JPA requires a mappedBy for the OneToMany, so this may be more difficult. You should be able to just add a JoinColumn on the OneToMany and make the column insertable/updateable=false.
    For the attachment, you could either map the foreign key as a Basic (DirectToFieldMapping) and maintain it in your model, or use a VariableOneToOne mapping in TopLink (this will require the entities share a common interface).

    You cannot use database link to define foreign key: see database link restrictions.

  • Inforation on Pool tables and cluster tables required.

    I want to know about the pool tables and cluster tables like how to create them and how to look the tables associated with the given tables. Like for the table BSEG we have other tables linked BSID etc. I'm new to this concept please guide me.

    <b>Pooled Table:</b>
    A pooled table in R/3 has a many-to-one relationship with a table in the database (see Figures 3.1 and 3.2). For one table in the database, there are many tables in the R/3 Data Dictionary. The table in the database has a different name than the tables in the DDIC, it has a different number of fields, and the fields have different names as well. Pooled tables are an SAP proprietary construct.
    When you look at a pooled table in R/3, you see a description of a table. However, in the database, it is stored along with other pooled tables in a single table called a table pool. A table pool is a database table with a special structure that enables the data of many R/3 tables to be stored within it. It can only hold pooled tables.
    R/3 uses table pools to hold a large number (tens to thousands) of very small tables (about 10 to 100 rows each). Table pools reduce the amount of database resources needed when many small tables have to be open at the same time. SAP uses them for system data. You might create a table pool if you need to create hundreds of small tables that each hold only a few rows of data. To implement these small tables as pooled tables, you first create the definition of a table pool in R/3 to hold them all. When activated, an associated single table (the table pool) will be created in the database. You can then define pooled tables within R/3 and assign them all to your table pool.
    Pooled tables are primarily used by SAP to hold customizing data.
    <b>Cluster Table:</b>
    A cluster table is similar to a pooled table. It has a many-to-one relationship with a table in the database. Many cluster tables are stored in a single table in the database called a table cluster.
    A table cluster is similar to a table pool. It holds many tables within it. The tables it holds are all cluster tables.
    Like pooled tables, cluster tables are another proprietary SAP construct. They are used to hold data from a few (approximately 2 to 10) very large tables. They would be used when these tables have a part of their primary keys in common, and if the data in these tables are all accessed simultaneously.
    Table clusters contain fewer tables than table pools and, unlike table pools, the primary key of each table within the table cluster begins with the same field or fields. Rows from the cluster tables are combined into a single row in the table cluster. The rows are combined based on the part of the primary key they have in common. Thus, when a row is read from any one of the tables in the cluster, all related rows in all cluster tables are also retrieved, but only a single I/O is needed.
    A cluster is advantageous in the case where data is accessed from multiple tables simultaneously and those tables have at least one of their primary key fields in common. Cluster tables reduce the number of database reads and thereby improve performance.
    Restrictions on Pooled and Cluster Tables
    1. Pooled and cluster tables are usually used only by SAP and not used by customers, probably because of the proprietary format of these tables within the database and because of technical restrictions placed upon their use within ABAP/4 programs. On a pooled or cluster table:
    2. Secondary indexes cannot be created.
    3. You cannot use the ABAP/4 constructs select distinct or group by.
    4.You cannot use native SQL.
    5.You cannot specify field names after the order by clause. order by primary key is the only permitted variation.
    For creation of pooled /cluster table, have  a look at below link.

  • Which type of information can be hold by pool and cluster tables

    hi experts tell me exactly which type of information hold by pooled and cluster tables
    thanks in advance

    Hi
    I hope, you know that Rewarding with Points for the Useful answers is the SDN policy
    Pooled table
    Pooled tables can be used to store control data (e.g. screen sequences,
    program parameters or temporary data). Several pooled tables can be
    combined to form a table pool. The table pool corresponds to a physical
    table on the database in which all the records of the allocated pooled
    tables are stored.
    Cluster table
    Cluster tables contain continuous text, for example documentation.
    Several cluster tables can be combined to form a table cluster. Several
    logical lines of different tables are combined to form a physical record
    in this table category. This permits object-by-object storage or
    object-by-object access. In order to combine tables in clusters, at
    least part of the keys must agree. Several cluster tables are stored in
    one corresponding table on the database.
    Pool Tables (match codes, look up tables)
    Should be accessed via primary key or
    Should be buffered (SE11->Display Table->technical settings)
    No secondary indexes
    Select * is Ok because all columns retrieved anyway
    Cluster Tables (BSEG,BSEC)
    Should be accessed via primary key - very fast retrieval otherwise very slow
    No secondary indexes
    Select * is Ok because all columns retrieved anyway. Performing an operation on multiple rows is more efficient than single row operations. Therefore you still want to select into an internal table. If many rows are being selected into the internal table, you might still like to retrieve specific columns to cut down on the memory required.
    Statistical SQL functions (SUM, AVG, MIN, MAX, etc) not supported
    Can not be buffered
