Table and structure

can anybody explain both table & structure and difference between them.
How these are used to create the functional spec.

both have fields in them but the main differnce is table can store data wheras structure can only  take the data but can not store it
if u are running a programme and the moment programme ends all the value mentioned in structure vanish out whereas if u have mentioned tha data in table fileds they would have get stored in database even after programme ends
as the name suggest structure is a structure of a body but it has no soul means u  it is created to avoid redundency
u can include a structure  in table but u cant include a structure in a table

    Go to Transaction SE80, Select Program and paste that program name below..
    Then drop down the tree of that program...then you will find option " Dict. Structures"..
    Here you can find the tables which has been you for that transaction / program.

  • Internal Table and Structures

    I am a beginer. I know how to create a structure and how to create an internal table using ABAP/4. My problem is, i don't understand where to use internal table and structure, also i find myself very confused about the explicit work areas.
    Plese someone show me a program by explaining all of this clearly.

    Internal tables are the core of ABAP. They are like soul of a body. For any program we use
    internal tables extensively. We can use Internal tables like normal data base tables only, but the
    basic difference is the memory allocated for internal tables is temporary. Once the program is
    closed the memory allocated for internal tables will also be out of memory.
    But while using the internal tables, there are many performance issues to be considered. i.e which
    type of internal table to be used for the standard internal table, hashed internal
    table or sorted internal table etc..
    Internal tables
    Internal tables provide a means of taking data from a fixed structure and storing it in working memory in ABAP. The data is stored line by
    line in memory, and each line has the same structure. In ABAP, internal tables fulfill the function of arrays. Since they are dynamic data
    objects, they save the programmer the task of dynamic memory management in his or her programs. You should use internal tables
    whenever you want to process a dataset with a fixed structure within a program. A particularly important use for internal tables is for
    storing and formatting data from a database table within a program. They are also a good way of including very complicated data
    structures in an ABAP program.
    Like all elements in the ABAP type concept, internal tables can exist both as data types and as data objects A data type is the abstract
    description of an internal table, either in a program or centrally in the ABAP Dictionary, that you use to create a concrete data object. The
    data type is also an attribute of an existing data object.
    Internal Tables as Data Types
    Internal tables and structures are the two structured data types in ABAP. The data type of an internal table is fully specified by its line type,
    key, and table type.
    Line type
    The line type of an internal table can be any data type. The data type of an internal table is normally a structure. Each component of the
    structure is a column in the internal table. However, the line type may also be elementary or another internal table.
    The key identifies table rows. There are two kinds of key for internal tables - the standard key and a user-defined key. You can specify
    whether the key should be UNIQUE or NON-UNIQUE. Internal tables with a unique key cannot contain duplicate entries. The uniqueness
    depends on the table access method.
    If a table has a structured line type, its default key consists of all of its non-numerical columns that are not references or themselves
    internal tables. If a table has an elementary line type, the default key is the entire line. The default key of an internal table whose line type
    is an internal table, the default key is empty.
    The user-defined key can contain any columns of the internal table that are not references or themselves internal tables. Internal tables
    with a user-defined key are called key tables. When you define the key, the sequence of the key fields is significant. You should remember
    this, for example, if you intend to sort the table according to the key.
    Table type
    The table type determines how ABAP will access individual table entries. Internal tables can be divided into three types:
    Standard tables have an internal linear index. From a particular size upwards, the indexes of internal tables are administered as trees. In
    this case, the index administration overhead increases in logarithmic and not linear relation to the number of lines. The system can access
    records either by using the table index or the key. The response time for key access is proportional to the number of entries in the table.
    The key of a standard table is always non-unique. You cannot specify a unique key. This means that standard tables can always be filled
    very quickly, since the system does not have to check whether there are already existing entries.
    Sorted tables are always saved sorted by the key. They also have an internal index. The system can access records either by using the
    table index or the key. The response time for key access is logarithmically proportional to the number of table entries, since the system
    uses a binary search. The key of a sorted table can be either unique or non-unique. When you define the table, you must specify whether
    the key is to be unique or not. Standard tables and sorted tables are known generically as index tables.
    Hashed tables have no linear index. You can only access a hashed table using its key. The response time is independent of the number of
    table entries, and is constant, since the system access the table entries using a hash algorithm. The key of a hashed table must be unique.
    When you define the table, you must specify the key as UNIQUE.
    Generic Internal Tables
    Unlike other local data types in programs, you do not have to specify the data type of an internal table fully. Instead, you can specify a
    generic construction, that is, the key or key and line type of an internal table data type may remain unspecified. You can use generic
    internal tables to specify the types of field symbols and the interface parameters of procedures . You cannot use them to declare data
    Internal Tables as Dynamic Data Objects
    Data objects that are defined either with the data type of an internal table, or directly as an internal table, are always fully defined in
    respect of their line type, key and access method. However, the number of lines is not fixed. Thus internal tables are dynamic data objects,
    since they can contain any number of lines of a particular type. The only restriction on the number of lines an internal table may contain are
    the limits of your system installation. The maximum memory that can be occupied by an internal table (including its internal administration)
    is 2 gigabytes. A more realistic figure is up to 500 megabytes. An additional restriction for hashed tables is that they may not contain more
    than 2 million entries. The line types of internal tables can be any ABAP data types - elementary, structured, or internal tables. The
    individual lines of an internal table are called table lines or table entries. Each component of a structured line is called a column in the
    internal table.
    Choosing a Table Type
    The table type (and particularly the access method) that you will use depends on how the typical internal table operations will be most
    frequently executed.
    Standard tables
    This is the most appropriate type if you are going to address the individual table entries using the index. Index access is the quickest
    possible access. You should fill a standard table by appending lines (ABAP APPEND statement), and read, modify and delete entries by
    specifying the index (INDEX option with the relevant ABAP command). The access time for a standard table increases in a linear relationship
    with the number of table entries. If you need key access, standard tables are particularly useful if you can fill and process the table in
    separate steps. For example, you could fill the table by appending entries, and then sort it. If you use the binary search option with key
    access, the response time is logarithmically proportional to the number of table entries.
    Sorted tables
    This is the most appropriate type if you need a table which is sorted as you fill it. You fill sorted tables using the INSERT statement. Entries
    are inserted according to the sort sequence defined through the table key. Any illegal entries are recognized as soon as you try to add
    them to the table. The response time for key access is logarithmically proportional to the number of table entries, since the system always
    uses a binary search. Sorted tables are particularly useful for partially sequential processing in a LOOP if you specify the beginning of the
    table key in the WHERE condition.
    Hashed tables
    This is the most appropriate type for any table where the main operation is key access. You cannot access a hashed table using its index.
    The response time for key access remains constant, regardless of the number of table entries. Like database tables, hashed tables always
    have a unique key. Hashed tables are useful if you want to construct and use an internal table which resembles a database table or for
    processing large amounts of data.
    Creating Internal Tables
    Like other elements in the ABAP type concept, you can declare internal tables as abstract data
    types in programs or in the ABAP Dictionary, and then use them to define data objects.
    Alternatively, you can define them directly as data objects. When you create an internal table as a
    data object, you should ensure that only the administration entry which belongs to an internal
    table is declared statically. The minimum size of an internal table is 256 bytes. This is important if an
    internal table occurs as a component of an aggregated data object, since even empty internal
    tables within tables can lead to high memory usage. (In the next functional release, the size of the
    table header for an initial table will be reduced to 8 bytes). Unlike all other ABAP data objects, you
    do not have to specify the memory required for an internal table. Table rows are added to and
    deleted from the table dynamically at runtime by the various statements for adding and deleting
    You can create internal tables in different types.
    You can create standard internal table and then make it sort in side the program.
    The same way you can change to hashed internal tables also.
    There will be some performance issues with regard to standard internal tables/ hashed internal
    tables/ sorted internal tables.
    Internal table types
    This section describes how to define internal tables locally in a program. You can also define internal tables globally as data types in the
    ABAP Dictionary.
    Like all local data types in programs , you define internal tables using the TYPES statement. If you do not refer to an existing table type
    using the TYPE or LIKE addition, you can use the TYPES statement to construct a new local internal table in your program.
    TYPES <t> TYPE|LIKE <tabkind> OF <linetype> [WITH <key>]
    [INITIAL SIZE <n>].
    After TYPE or LIKE, there is no reference to an existing data type. Instead, the type constructor occurs:
    <tabkind> OF <linetype> [WITH <key>]
    The type constructor defines the table type <tabkind>, the line type <linetype>, and the key <key> of the internal table <t>.
    You can, if you wish, allocate an initial amount of memory to the internal table using the INITIAL SIZE addition.
    Table type
    You can specify the table type <tabkind> as follows:
    Generic table types
    For creating a generic table type with index access.
    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
    For creating standard tables.
    For creating sorted tables.
    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.
    Line type
    For the line type <linetype>, you can specify:
    Any data type if you are using the TYPE addition. This can be a predefined ABAP type, a local type in the program, or a data type from the
    ABAP Dictionary. If you specify any of the generic elementary types C, N, P, or X, any attributes that you fail to specify (field length, number
    of decimal places) are automatically filled with the default values. You cannot specify any other generic types.
    Any data object recognized within the program at that point if you are using the LIKE addition. The line type adopts the fully-specified data
    type of the data object to which you refer. Except for within classes, you can still use the LIKE addition to refer to database tables and
    structures in the ABAP Dictionary (for compatibility reasons).
    All of the lines in the internal table have the fully-specified technical attributes of the specified data type.
    You can specify the key <key> of an internal table as follows:
    [UNIQUE|NON-UNIQUE] KEY <col1> ... <col n>
    In tables with a structured line type, all of the components <coli> belong to the key as long as they are not internal tables or references,
    and do not contain internal tables or references. Key fields can be nested structures. The substructures are expanded component by
    component when you access the table using the key. The system follows the sequence of the key fields.
    If a table has an elementary line type (C, D, F, I, N, P, T, X), you can define the entire line as the key. If you try this for a table whose line
    type is itself a table, a syntax error occurs. If a table has a structured line type, it is possible to specify the entire line as the key. However,
    you should remember that this is often not suitable.
    This declares the fields of the default key as the key fields. If the table has a structured line type, the default key contains all non-numeric
    columns of the internal table that are not and do not contain references or internal tables. If the table has an elementary line type, the
    default key is the entire line. The default key of an internal table whose line type is an internal table, the default key is empty.
    Specifying a key is optional. If you do not specify a key, the system defines a table type with an arbitrary key. You can only use this to
    define the types of field symbols and the interface parameters of procedures . For exceptions, refer to Special Features of Standard Tables.
    The optional additions UNIQUE or NON-UNIQUE determine whether the key is to be unique or non-unique, that is, whether the table can
    accept duplicate entries. If you do not specify UNIQUE or NON-UNIQUE for the key, the table type is generic in this respect. As such, it can
    only be used for specifying types. When you specify the table type simultaneously, you must note the following restrictions:
    You cannot use the UNIQUE addition for standard tables. The system always generates the NON-UNIQUE addition automatically.
    You must always specify the UNIQUE option when you create a hashed table.
    Initial Memory Requirement
    You can specify the initial amount of main memory assigned to an internal table object when you define the data type using the following
    This size does not belong to the data type of the internal table, and does not affect the type check. You can use the above addition to
    reserve memory space for <n> table lines when you declare the table object.
    When this initial area is full, the system makes twice as much extra space available up to a limit of 8KB. Further memory areas of 12KB each
    are then allocated.
    You can usually leave it to the system to work out the initial memory requirement. The first time you fill the table, little memory is used. The
    space occupied, depending on the line width, is 16 <= <n> <= 100.
    It only makes sense to specify a concrete value of <n> if you can specify a precise number of table entries when you create the table and
    need to allocate exactly that amount of memory (exception: Appending table lines to ranked lists). This can be particularly important for
    deep-structured internal tables where the inner table only has a few entries (less than 5, for example).
    To avoid excessive requests for memory, large values of <n> are treated as follows: The largest possible value of <n> is 8KB divided by the
    length of the line. If you specify a larger value of <n>, the system calculates a new value so that n times the line width is around 12KB.
    The program defines a table type ITAB. It is a sorted table, with line type of the structure LINE and a unique key of the component
    The program defines a table type VECTOR with type hashed table, the elementary line type I and a unique key of the entire table line. The
    second table type is the same as in the previous example. The structure DEEPLINE contains the internal table as a component. The table
    type DEEPTABLE has the line type DEEPLINE. Therefore, the elements of this internal table are themselves internal tables. The key is the
    default key - in this case the column FIELD. The key is non-unique, since the table is a standard table.
    Internal table objects
    Internal tables are dynamic variable data objects. Like all variables, you declare them using the DATA statement. You can also declare static
    internal tables in procedures using the STATICS statement, and static internal tables in classes using the CLASS-DATA statement. This
    description is restricted to the DATA statement. However, it applies equally to the STATICS and CLASS-DATA statements.
    Reference to Declared Internal Table Types
    Like all other data objects, you can declare internal table objects using the LIKE or TYPE addition of the DATA statement.
    DATA <itab> TYPE <type>|LIKE <obj> [WITH HEADER LINE].
    Here, the LIKE addition refers to an existing table object in the same program. The TYPE addition can refer to an internal type in the
    program declared using the TYPES statement, or a table type in the ABAP Dictionary.
    You must ensure that you only refer to tables that are fully typed. Referring to generic table types (ANY TABLE, INDEX TABLE) or not
    specifying the key fully is not allowed (for exceptions, refer to Special Features of Standard Tables).
    The optional addition WITH HEADER line declares an extra data object with the same name and line type as the internal table. This data
    object is known as the header line of the internal table. You use it as a work area when working with the internal table (see Using the
    Header Line as a Work Area). When you use internal tables with header lines, you must remember that the header line and the body of the
    table have the same name. If you have an internal table with header line and you want to address the body of the table, you must indicate
    this by placing brackets after the table name (<itab>[]). Otherwise, ABAP interprets the name as the name of the header line and not of the
    body of the table. You can avoid this potential confusion by using internal tables without header lines. In particular, internal tables nested
    in structures or other internal tables must not have a header line, since this can lead to ambiguous expressions.
    MOVE ITAB TO JTAB. <- Syntax error!
    The table object ITAB is created with reference to the table type VECTOR. The table object JTAB has the same data type as ITAB. JTAB also
    has a header line. In the first MOVE statement, JTAB addresses the header line. Since this has the data type I, and the table type of ITAB
    cannot be converted into an elementary type, the MOVE statement causes a syntax error. The second MOVE statement is correct, since
    both operands are table objects.
    Declaring New Internal Tables
    You can use the DATA statement to construct new internal tables as well as using the LIKE or TYPE addition to refer to existing types or
    objects. The table type that you construct does not exist in its own right; instead, it is only an attribute of the table object. You can refer to
    it using the LIKE addition, but not using TYPE. The syntax for constructing a table object in the DATA statement is similar to that for defining
    a table type in the TYPES statement.
    DATA <itab> TYPE|LIKE <tabkind> OF <linetype> WITH <key>
    [INITIAL SIZE <n>]
    As when you define a table type , the type constructor
    <tabkind> OF <linetype> WITH <key>
    defines the table type <tabkind>, the line type <linekind>, and the key <key> of the internal table <itab>. Since the technical attributes of
    data objects are always fully specified, the table must be fully specified in the DATA statement. You cannot create generic table types (ANY
    TABLE, INDEX TABLE), only fully-typed tables (STANDARD TABLE, SORTED TABLE, HASHED TABLE). You must also specify the key and whether
    it is to be unique (for exceptions, refer to Special Features of Standard Tables).
    As in the TYPES statement, you can, if you wish, allocate an initial amount of memory to the internal table using the INITIAL SIZE addition.
    You can create an internal table with a header line using the WITH HEADER LINE addition. The header line is created under the same
    conditions as apply when you refer to an existing table type.
    The table object ITAB has the type hashed table, a line type corresponding to the flat structure SPFLI from the ABAP Dictionary, and a
    unique key with the key fields CARRID and CONNID. The internal table ITAB can be regarded as an internal template for the database table
    SPFLI. It is therefore particularly suitable for working with data from this database table as long as you only access it using the key.

  • Difference between Table and Structure

    Dear SD Gurus,
    Can anybody tell me what is the difference between a Table and Structure
    Pls Reply.

    Tables are Database, which stay in system for long duration , as good as permanent, untill & unless the data is archived, which is not very frequent. Data at transaction level are captured from multiple tables, so as to meet the requirement. We can view the data in the table through T.code SE11 & SE16. there are certain tables in which data can be maintained as well as displayed. To maintain data, we use T.Code: SM30 or SM31.
    Structures are temporary table & hold the data for that particular instance or transaction.

  • How to pass the JCO Table and Structure in a collection List to frontEnd

    I have a BAPI which is returns me a Table and a structure. As i have used JCO I will receive it in JCO Table and JCO Structure. Now the question is that how I should pass both these of these using a collection to the frontend for displaying the data from it.
    Thanks' & Regards,

    Hi Samir,
    As you are trying to pass the Table and the Structure in the form of collection to the JSP page, you can create a javabean with the structure similar to that of the table/Structure.
    Lets assume you have a table called Employee with Emp_Name, Emp_Age, Emp_Sal as three columns, create a java class by name Employee which implements Serializable and attributes as Emp_Name, Emp_Age and Emp_Sal. Generate the setters and getters for the same. In your EJB code, create an instance of this Employee class and set the attributes and save it in a HashMap in the form of key value pair, Value being your Employee class instance and key be your Employee Name. Return the HashMap in your EJB code.
    Use the HashMap in your JSP. Get the Iterator for the HashMap and Loop through the keys to get the values.
    Hope this helps.

                  anzle lgpla lgtyp art anzhoehe fa
    FROM    zle_lagerplanung INTO CORRESPONDING FIELDS OF TABLE it_zle_lagerplanung
    WHERE  kdauf IN s_kdauf
    AND       KDPOS IN s_kdpos
    AND      werk = p_werks.
    But while updating the particular field in zle_lagerplanung using this statement
    UPDATE zle_lagerplanung from table it_zle_lagerplanung.
    it is giving syntax error
    "The type of the database table and work area (or internal table)
    "IT_ZLE_LAGERPLANUNG" are not Unicode convertible. "
    Could any one help me out how to resolve this problem....
    Thanks in advance

    Dear Shayamal,
    XXX....are not Unicode convertible
    This  error comes while inserting or updating database and the fields are not matching between  data base table and structure .
    Check you fields of data base table and  "zle_lagerplanung" and struture "it_zle_lagerplanung" . There fields must match.
    thanks and regrds,

  • Append data to a nested table within structure

    I am trying to write some code (not really an ABAPer but helping out) and my code is not quite working.
    i have a structure that is made up of up three tables and a structure.  it is part of an DIMP add on.
    I have typed my tables and structures and tables in line with target definition, however my data is not being passed across...
    i have tried a number of different ways of doing this, but have been unsuccessful.  I am sure i am close, but would like some guidance...
             LOOP AT gt_mpdcycle INTO gs_mpdcycle.
                APPEND gs_mpdcycle TO gs_create_mpd-cycledata.
                INSERT gs_create_mpd-cycledata INTO gs_create_mpd.
    the gs_create_mpd is typed to the overall structure...  the gt_mpdcycle is typed to table of mpdcycle and gs_mpdcycle is typed to mpdcycle structure.  the gs_create_mpd-mpdcycle is typed as type table of mpdcycle.
    i have also tried the following:
    gs_create_mpd-cycledata[] = gt_mpdcycle[].
    INSERT gt_mpdcycle INTO gs_create_mpd-cycledata.
    does that make sense?  can someone suggest a way of doing this?

    I knew i was close!
              LOOP AT gt_mpdcycle INTO gs_mpdcycle.
                APPEND gs_mpdcycle TO gs_create_mpd-cycledata.
    *            INSERT gs_create_mpd-cycledata INTO gs_create_mpd.

  • Structure of table and work area are not compatible - table control wizard

    Structure of table and work area are not compatible is the error i am getting when specifying my internal table and work area in my table control?  What am I doing wrong?

    this error comes when you have different structure of work area then internal work area will not work here and you will not be able to append records in internal table.
    check strucure of internal table and work should be like below.
      BEGIN OF type_s_kna1,
         kunnr LIKE kna1-kunnr,            " Customer Number
         name1 LIKE kna1-name1,            " Name
         vbeln LIKE vbap-vbeln,            " Sales Document
      END OF type_s_kna1.

      DATA : t_kna1 TYPE STANDARD TABLE OF type_s_kna1,
             fs_kna1 TYPE type_s_kna1.

  • What is the concept behind using table PA0002 and structure p0002.

    What is the concept behind using table PA0002 and structure p0002.
    Many times, I have seen Looping at structure e.g. p0002, p0006 etc. and data is processed and also seen Looping at table PA0002, PA0006 etc. with further appropriate subtypes if any to retrieve a value and process the same.
    In which context tables like PA,HRP,IT etc. are used and structures p0001,p0002 etc. are used.

    As mentioned  that that Structure Pnnnn is user as a internal tablw when a LDB is used.
    INFOTYPES: 0001.
      GET PERNR.
        WRITE:  / P0001-PERNR,
    Here it is important to declare the infotypes you want to read  and so the system will create internal tables  ex. P0001.
    Tables PA0001 are database table with following fields
    .INCLUDE   PS nnnn

  • View on a table and a structure

    I have a table STPO and  a structure STPOB .
    in the structure STPOB it is calling the table STPO mentioned above
    i have to create a generic data source with these tables.
    is it valid to create a view on a table and a structure .
    do i have to write code to populate
    how should i proceed. could you pls update me.

    I have two reports i have to create a generic datasource
    1. PRODUCTION ORDERS AND DETAILS OF COMPONENTS( data comes from RESB table only)
    The data for 2nd report is ffetched from RESB and AFKO TABLES.
    To track the changes in RESB table.
    Addition of the components manually in the production order, we can track
    through the change date for master data field (AUFK - AEDAT). For each time
    when we are adding the components, the system will create a new line item in
    RESB - OBJNR. BY change mode only we can add the new components in the
    production order.
    Planned order reservation changes we can track through the MRP date (MDKP -
    1. i have to pull the data for production orders and details of components.
    ie from table RESB ONLY
    2.I have to pull the data for reservation of production orders from RESB &
    AFKO table
    how should i create a generic datasource with above information without
    failing to pull deltas
    I want to create a generic extractor
    my further doubts are i have to create a single extractor( since both the
    reports are using RESB table) or two different extractors.
    2. if at all i go for single or two serparate extractors what would be the delta fields

  • What the difference and use between   of  TABLES and SY-REPID?

    I have came accross 2 cases that i can't able understand
    TABLES: VBAP   -
    >( Here also Appplication Server(AS) creates Wrokarea of Structure VBAP but, by 
    data: v_vbeln like vbap-vbeln.    double clicking on variable v_vbeln AS taking me to DDIC VBAP table VBELN field then what the using declaring tables. )
    ( and ) 
    DATA: VBAP TYPE VBAP -->( Here also Appplication Server(AS) creates Wrokarea of Structure VBAP data: v_vbeln like vbap-vbeln.    but,double clicking on variable v_vbeln AS taking me to user declared VBAP
                                                  i.e., above DATA declaration statement )
    Then Which one is better in Functionality wise as well as Performance wise or when we have to go for TABLES and when we have to go for DATA declaration of DDIC objects.
    what the difference between
    I know that SY_REPID is not a system variable. And also that
    Data: vrepid type SY_REPID.--> Predefined data type in ABAP
    Data: vrepid like SY_REPID.-> Predefined Constatnt in ABAP( it is a constant it allowing with out VALUE                                                                               
    what difference between them and when we have to go Data: vrepid type SY_REPID and when we have to go Data: vrepid like SY_REPID.
    Thank U,
    Shabeer Ahmed.

    Hi Ahmed,
      VBAP.   " DDIC
      v_vbeln like vbap-vbeln.
    *Here you are using the DDIC VBAP
      vbeln like vbap-vbeln.
    *Here you are using the local data object as your data type so it will always
    * take you to user declared VBAP which is declared by you.
      vbeln like vbap-vbeln.
    * here its using T_VBAP not DDIC VBAP
    And for performance always the second option is better, use Data instead of tables, declare your own local structure.
      vrepid type SY_REPID.  thereis nop redefined data type in ABAP as SY_REPID
    * its SY-REPID which is a system variable.
      vrepid type SY-REPID.
    Also refer to the links:
