    *DELETE SOURCE_PACKAGE where BAL_FLAG = 'X'. I had made comment to allow the G/L accounts. since I have some GL Accounts which does'nt have the cost center data, so in this case I have to write a ABAP code to allow this G/L accounts with cost center data.
    So Let me know if anyone can help me how to write the ABAP code in the start routine.

  • How to write the expression when create the calculated column?

    Dear,
           I want to create some calculated column in my attribute view, but I don't know how to write the code in the expression, is there any introduction about this part, how to use those function and how about the grammar in this expression code ?  or is there any example about this calculated column?
       Thanks for your sincerely answer.

    Hi Zongjie,
    you can find some information about the creation of calculated columns in the HANA Modeling Guide (http://help.sap.com/hana/SAP_HANA_Modeling_Guide_for_SAP_HANA_Studio_en.pdf).
    Within chapter 6.2.1 (Create Analytic Views) you can see under point 7 some basics and also a simple example. The same is also valid for Calculation Views.
    Chapter 8.9 (Using Functions in Expressions) describes the different available functions.
    You also can use the integrated search in the HANA Studio by clicking the "?" button in the button left corner. Then you get some links in the side panel with related information.
    In general you can write your expression manually or you can just drag and drop the functions, elements, operators into the editor window. For example if you drag and drop the "if" function into the editor window you get "if(intarg,arg2,arg3)" inserted. The arguments can be replaced manually or also by drag and drop.
    It is also worse to use the "Validate Syntax" button on top of the editor window. It gives you directly a feedback if your expression syntax is correct. If not you get some helpful information about the problem (ok, sometimes it is a little bit confusing because of the cryptic error message format ).
    Best Regards,

  • How to Capitalize the first letter or an entire word using a shortcut on the keyboard just like in microsoft that uses shift+F3

    please how can one How to Capitalize the first letter or an entire word using a shortcut on the keyboard just like in microsoft that uses shift+F3

    What do you mean there was "no effect?" I'm not aware of any effects.
    It looks like that Service is also in the App Store. From their screen shots, the services are prefaced with WordService:
    You can see an example in the App Store for their app: App Store
    After installing, you should now have those text services in your Services menu. You can then add shortcuts in the Keyboard System Prefs.
    Most Apple apps have a Transformations menu in the Edit menu. You can Make upper, lower, and Initial caps with those. I would stick with Word Services, but you can make Application Shortcuts for the items in the Transformations menu.
    Again, in Keyboard System Prefs, Under Applications, Click the Add button on the right side pane.
    Set it for All Applications
    Enter the menu command exactly as they appear in the Transformation menu (separate entries for each),
    Make Upper Case
    Make Lower Case
    Capitalize
    Give them a shortcut.

  • How to write the exceptions in function module

    dear all,
         how to write the exceptions in function modules with example.
    thanq
    jyothi

    Hi,
    Raising Exceptions
    There are two ABAP statements for raising exceptions. They can only be used in function modules:
    RAISE except.
    und
    MESSAGE.....RAISING except.
    The effect of these statements depends on whether the calling program handles the exception or not. The calling program handles an exception If the name of the except exception or OTHERS is specified after the EXCEPTION option of the CALL FUNCTION statement.
    If the calling program does not handle the exception
    · The RAISEstatement terminates the program and switches to debugging mode.
    · The MESSAGE..... RAISING statement displays the specified message. Processing is continued in relation to the message type.
    If the calling program handles the exception, both statements return control to the program. No values are transferred. The MESSAGE..... RAISING statement does not display a message. Instead, it fills the system fields sy-msgid, sy-msgty, sy-msgno , and SY-MSGV1 to SY-MSGV4.
    Source Code of READ_SPFLI_INTO_TABLE
    The entire source code of READ_SPFLI_INTO_TABLE looks like this:
    FUNCTION read_spfli_into_table.
    ""Local Interface:
    *" IMPORTING
    *" VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
    *" EXPORTING
    *" VALUE(ITAB) TYPE SPFLI_TAB
    *" EXCEPTIONS
    *" NOT_FOUND
    SELECT * FROM spfli INTO TABLE itab WHERE carrid = id.
    IF sy-subrc NE 0.
    MESSAGE e007(at) RAISING not_found.
    ENDIF.
    ENDFUNCTION.
    The function module reads all of the data from the database table SPFLI where the key field CARRID is equal to the import parameter ID and places the entries that it finds into the internal table spfli_tab. If it cannot find any entries, the exception NOT_FOUND is triggered with MESSAGE ... RAISING. Otherwise, the table is passed to the caller as an exporting parameter.
    Calling READ_SPFLI_INTO_TABLE
    The following program calls the function module READ_SPFLI_INTO_TABLE:
    REPORT demo_mod_tech_fb_read_spfli.
    PARAMETERS carrier TYPE s_carr_id.
    DATA: jtab TYPE spfli_tab,
    wa LIKE LINE OF jtab.
    CALL FUNCTION 'READ_SPFLI_INTO_TABLE'
    EXPORTING
    id = carrier
    IMPORTING
    itab = jtab
    EXCEPTIONS
    not_found = 1
    OTHERS = 2.
    CASE sy-subrc.
    WHEN 1.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
    WHEN 2.
    MESSAGE e702(at).
    ENDCASE.
    LOOP AT jtab INTO wa.
    WRITE: / wa-carrid, wa-connid, wa-cityfrom, wa-cityto.
    ENDLOOP.
    The actual parameters carrier and jtab have the same data types as their corresponding interface parameters in the function module. The exception NOT_FOUND is handled in the program. It displays the same message that the function module would have displayed had it handled the error.
    Or
    just have to decide what exceptions u want and under what conditions.
    then declarethese exeptions under the exceptions tab.
    in the source code of ur function module.
    if
    like this u can code .
    now when u call the function module in tme mainprogram.
    if some error occurs and u have declared a exception for this then it will set sy-subrc = value u give inthe call of this fm.
    in the fm u can program these sy-subrc values and trigger the code for ur exception.
    Please reward if useful

  • How to write the dynamic code for RadioGroupByKey and Check Boxes?

    Hi,
    Experts,
    I have created a WD ABAP application in that i have used RadioGroupByKey and CheckBox Ui elements but i want how to write the dynamic code to that i want to display male and female to RadioGroupByKey and 10  lables to check boxs.
    Please pass me some idea on it and send any documents on it .
    Thanks in advance ,
    Shabeer ahmed.

    Refer this for check box:
    Do check :
    bind_checked property is bind to a node with cardinality of 1:1
    CHECK_BOX_NODE <---node name
    -CHECK_BOX_VALUE <--attribute name of type wdy_boolean
    put this code under your WDDOMODIFYVIEW:
    DATA:
    lr_container TYPE REF TO cl_wd_uielement_container,
    lr_checkbox TYPE REF TO cl_wd_checkbox.
    get a pointer to the RootUIElementContainer
    lr_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
    lr_checkbox = cl_wd_checkbox=>new_checkbox(
    text = 'WD_Processor'
    bind_checked = 'CHECK_BOX_NODE.CHECK_BOX_VALUE'
    view = view ).

  • How to write the sql statement of my finder function in cmp?

    hi,
    I create a cmp ejb from table INFOCOLUMN,and I create a my finder function ,which sql statement is :
    select * from INFOCOLUMN WHERE employee_id=id
    employee_id is a column of the table,and id is the finder function parameter.
    The error is : invalid column name
    So,how to write the sql statement.
    Thanks .

    Mole-
    Bind variables are of the form $1, $2, etc., so your query stmt should look like:
    select * from INFOCOLUMN WHERE employee_id=$1
