Internal table question

Hi Everybody-
I am very new to SAP and i have question regarding internal tables. I have struture called "ZMI_VENDOR_TO_BW_GENERIC_V_TAB" which i get from another sap system thru SAP XI. Now i need to traverse thru this structure  and add these values into custom database table. So i have declared an internal table like below
<b>data:itab_venkat type ZMI_VENDOR_TO_BW_GENERIC_V_TAB occurs 10.
  data vendorid type c.
  itab_venkat = Input-Generic_Vendor-Generic_Vendor_Record1.
  LOOP AT itab_venkat.
  vendorid = itab_venkat-generic_vendor_id1.
endloop.
</b>
i am getting an error saying occurs cannot be used and also getting an error at the loop statement, Can somebody please correct me, i am very new to SAP.in the loop i am getting the vendor id and then i should update the database table.
Please help me.
Thank you
Venkat

  • 'Search' internal table - sy-tabix question

    I realize there are many questions out there on sy-tabix but non that answer my question. 
    I have an internal table that will be filled with material numbers (among other things).  I need to loop through the internal table to see if the material number already exists in the table.  If so I need to store the index of the material number.  What is the best way to go about doing this?
    Regards,
    Davis

    Thanks Ravi, I guess instead of
    WRITE: / sy-tabix I can have something like
    LineIndex = sy-tabix.  is that correct?
    I wasn't sure if I could do something like
    READ TABLE itab WITH KEY matnr....
    I thought that I had to include a string that was searched through the whole table like the example in the online help.  Thanks again!
    Davis.
    I'm keeping this question open to see what other suggestions I receive.

  • Question in ABAP syntax, read & insert data from internal table, while loop

    Hi, SDN Fellow.
    I am from Java background and learnt ABAP, I don't usually write much ABAP code.
    I am trying to implement the following logic in a RFC now.
    I have one z-custom database table, the structure as the following:
    It has two columns, with these sample data.
    Says datable table is ZEMPMGRTAB.
    EmployeeID,ManagerID
    user10,user1
    user9,user1
    user8,user1
    user7,user2
    user6,user2
    user5,user2
    user4,user2
    user2,user1
    The logic is this:
    I have a input parameter, userid. I am using this parameter to have a select statement to query the record into export table,EXPTAB 'LIKE' table ZEMPMGRTAB.
    SELECT * FROM  ZEMPMGRTAB
      into table EXPTAB
       WHERE  EMPLOYEEID  = USERID.
    Say, my parameter value, USERID ='USER4'.
    Referring to the sample data above, I can get the record of this in my EXPTAB,
    EmployeeID,ManagerID
    user4,user2
    Now, I want to iterately use the EXPTABLE-ManagerID
    as the USERID input in SELECT statement, until it has no return result. Then, insert the new records in
    EXPTAB.
    In above new loop case, we will get this table content in EXPTAB,
    EmployeeID,ManagerID
    user4,user2
    user2,user1
    I kind of think of the pseudocode logic as below:
    (These may not be a valid ABAP code, so I need help to convert/correct them)
    DATA:
    IWA TYEP ZZEMPMGRTAB,
    ITAB
    HASHED TABLE OF ZZEMPMGRTAB
    WITH UNIQUE KEY EMPLOYEEID.
    SELECT * FROM  ZEMPMGRTAB
      into table ITAB
       WHERE  EMPLOYEEID  = USERID.
    *Question 1: I cannot insert a internal table to export table, it is *incompatible type, what is the alternative way fo this?
    *Question 2: How can I access thedata of the internal table like this,ITAB-MANAGERID? As if I can, I would do this:
    * IWA-EMPLOYEEE = ITAB-EMPLOYEEID. IWA-MANAGERID = IWA-MANAGERID. INSERT IWA INTO TABLE EXPTAB.
    * Question 3: Is the 'NE NULL' - 'not equal to NULL' is right syntax?
    IF ITAB NE NULL.
    INSERT ITAB INTO EXPTAB.
    ENDIF
    * Question 4: Is my WHILE loop setup right here? And are the syntax right?
    WHILE ITAB NE NULL.
    SELECT * FROM  ZEMPMGRTAB
      into table ITAB
       WHERE  EMPLOYEEID  = ITAB-MANAGERID.
    IF ITAB NE NULL.
    INSERT ITAB INTO EXPTAB.
    ENDIF
    REFRESH ITAB.
    ENDWHILE.
    Assume all the syntax and logic are right, I should get this result:
    EmployeeID,ManagerID
    user4,user2
    user2,user1
    If I have a new entry in datable table,ZEMPMGRTAB like this:
    user1,user0
    My pseudocode logic will get this result:
    EmployeeID,ManagerID
    user4,user2
    user2,user1
    user1,user0
    I truly appreciate if you can help me to validate the above syntax and pseudocode logic.
    Thanks in advance.

  • Question,Get data from ALV to internal table

    Hi, friends
    I currently need to get the data displayed on ALV.
    But the original internal table is local.
    It means it has already been deleted.
    Do you know which method I shoud use?
    After that, I will move the records to other internal
    table.
    3Q
    Minghan

    Hi,
    are you using ALV list/GRID FM,
    Check this..,
    1. why can't you declare the internal table as Global.
    2. you can call the FM
    REUSE_ALV_LIST_LAYOUT_INFO_GET
    here you get the table data using the table parameter <b>ET_OUTTAB</b>
    try this...
    where you will try?( when ever you want , please let me know where exactly you need this)

  • Question about reading csv file into internal table

    Some one (thanks those nice guys!) in this forum have suggested me to use FM KCD_CSV_FILE_TO_INTERN_CONVERT to read csv file into internal table. However, it can be used to read a local file only.
    I would like to ask how can I read a CSV file into internal table from files in application server?
    I can't simply use SPLIT as there may be comma in the content. e.g.
    "abc","aaa,ab",10,"bbc"
    My expected output:
    abc
    aaa,ab
    10
    bbb
    Thanks again for your help.

    What are internal tables? How do you get the number of lines in an internal table? How to use a specific number occurs statement?

    hi,

    An internal table is one of two structured data types in ABAP. It can contain any number of identically structured rows, with or without a header line.
    The header line is similar to a structure and serves as the work area of the internal table. The data type of individual rows can be either elementary or structured.
    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.
    Fields of Internal Tables
    SY-TABIX
    Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
    APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
    COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
    LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
    READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
    SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
    SY-TFILL
    After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TFILL contains the number of lines in the relevant internal table.
    SY-TLENG
    After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TLENG contains the length of the lines in the relevant internal table.
    SY-TOCCU
    After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TLENG contains the initial amount of memory allocated to the relevant internal table.
    i think this will solve your problem don't forget to reward points.

  • Question on internal table logic..

    Gurus,
    I have a internal table as follows:
    it_tab:
    ID---ACTION---CHANGE
    A1-----X--
    B2----
    U
    C1-----X--
    U
    C2-----X--
    Without looping at the table, how can I find get the result that the internal table has 3 ids with ACTION ='X'
    and 1 ID with ACTION  = X and Change = U.
    Regards,
    Rajesh.

    I agree with Rob, why not loop?
    First thing without loop that comes to mind is
    Using the Read statement 4 times with index 1,2,3 & 4.

    DNP

  • Dumb question about monodimensional internal tables

    Hi all gurus,
    in ABAP/4 it is possible to define an internal table made up by a single field , so that we could consider such a declaration:
    DATA: itab TYPE TABLE OF EBELN
    as a single-dimension array.
    Now, supposing I want to fast access this vector directly with a read table... I don't have an explicit field name to refer to in the WITH KEY clause.
    My workaround actually is to define such a vector in this way:
    DATA: begin of itab,
                doc_no TYPE EBELN,
                end of itab.
    so that a fast READ TABLE statement can be possible specifying the WITH TABLE clause in this way:
    READ TABLE itab WITH KEY doc_no = <valuetosearchfor>  .
    Anyway, I'm wondering if these ops are possible even in an itab defined in the first form, without the need of defining a specific itab structure. In many situation I find mono-dimensional tables really useful, I'd like to avoid every time an explicit DATA type def.

    Hello,
    I dont know if this is what you are looking for. You can use the addition:
    ... WITH TABLE KEY [keyname COMPONENTS] ...
    SAp documentation also adds:
    The pseudo component table_line can be specified as a component for tables with an unstructured row type, if their whole table entry is defined as a table key.
    For more details on psuedo components read this : [http://help.sap.com/abapdocu_70/en/ABENITAB_COMPONENTS.htm|http://help.sap.com/abapdocu_70/en/ABENITAB_COMPONENTS.htm]

  • Question about Subroutine and Internal tables

    See I  have this code.
    TABLES: SFLIGHT.
        TYPES: BEGIN OF LINE,

               Connid like SFLIGHT-CONNID,
               Fldate like SFLIGHT-FLDATE,
               Seatsmax like SFLIGHT-SEATSMAX,
               Seatsocc like SFLIGHT-SEATSOCC,
               Percen type p decimals 2,
               END OF LINE.
       DATA: ISFLIGHT TYPE STANDARD TABLE OF LINE INITIAL SIZE 10 WITH HEADER LINE.
       DATA: Percent type p decimals 2.
       PARAMETERS: CID LIKE SFLIGHT-CARRID.

       INITIALIZATION.
       CID = '004'.
       SELECT CARRID CONNID FLDATE  SEATSMAX  SEATSOCC FROM SFLIGHT INTO TABLE ISFLIGHT WHERE CARRID = CID.
    So far I've gotten this far. but now I need to compute for the percentage, which I'm required to do in a subroutine.
    So I tried
    FORM U TABLES ISFLIGHT STRUCTURE SFLIGHT.
    ISFLIGHT-Percen = ( ISFLIGHT-Seatsocc / ISFLIGHT-Seatsmax ) * 100.
    ENDFORM.
    But I keep getting an error o that. It keeps telling me that ISFLIGHT does not have a Percen field. Also I'm suppose to use a pass by value to this subroutine but I don't know what that means.
    Basically I need to compute for the percentage and insert it tot he internal table. which I would sort by percentage. After which I'm suppose to print the ouput by passing the internal table to the subroutine.
    I know I'm doing something wrong but I just don't know how to fix this since I only started working on subroutines today. Any help would be appreciated.

    Hi Abhay,
          If you go to Transaction code SE93, enter the tcode "CK86_99" and click display, you may see the default value for transaction is "KKBB" and the screen field for P_SCREEN = 0300, P_TCODE = ck86_99.
          You may need to copy the transaction code "KKBB" and go to SE93 again, enter the tcode for "KKBB" then click display, now you may see the program name is "RKKB1000".
          Hope this answer your question.
    Thanks
