Exception on a select condition in a Function Module

Abap Experts,
I have function module. The selection conditions fails sometimes. Even if it fails I want to carry out the remaining part of the function module.
Wondering how to create a exception on a selection condition.
Any suggestions appreciated.
Many thanks in advance.
BWer

Don't clear your problem.
Your function module is created by you?
if so, you can check the select result of select, like this:
SELECT XXXX
  FROM XXX
WHERE ....
IF SY-SUBRC = 0.
SELECT SUCCESS
ELSE.
SELECT FAILED
ENDIF.
Does it what you want?  if not, please explain more details about your problem.

  • Start conditions and check function modules

    Hi,
    When we apply start conditions to any particular even linkage you will find check function module as SWB_2_CHECK_FB_START_COND_EVAL. However, what if i want to implement both a custom check function module AND start conditions ?
    My requirement is to implement both start conditions and check function module.
    Is this possible ?
    Thank you,
    Nikhil.

    Hi,
    You can use both of the things, however its advisable to check all start conditions if you are using check FM.
    This is interface for custom  check FM,once you have the key value, you can put all the checks here
    *"*"Local Interface:

  • Calling a Selection Screen from a Function Module/Method

    Hi,
      I would like to call a selection screen from a function module or method. I understand it is not possible by the definition. Are there any alternative options as I am looking for the Variants Save option on the screen. Any thoughts?
    Thanks
    Raghav

    Since i don't know your exact requirements (standard SAP selection screen? your own selection screen?) the onl;y thing i can come up with is:
    1. in your function pool create your own screen with a subscreen area
    2. create your own selection screen as a subscreen.
    3. include the selection subscreen in the first screen
    4. call the first screen in your function.

  • Data transfer of Selected sets (QS51) using Function modules

    Hi All,
    I am doing data migration of Selected sets (TCODE QS51) using function module. I have tried using BDC recording but it is not working in background.In foreground it is giving information error on second screen as field  RQSKT-AUSWAHLMGE is not present on screen 1000..  In foreground I am pressing enter after this error its working fine but in background the execution stops there. So I am trying function modules QPAM_SELSET_CODE_CREATE  and QPAM_SELECTED_SET_CREATE
    The fields in template I have are KATALOGART(Catalog), WERKS(Plant),AUSWAHLMGE(Selected set) ,KTX01(short text), STATUS(status),CODEGRUPPE(code group), CODE (code), KURZTEXT (short text for codegroup),BEWERTUNG(Valuation code), FEHLKLASSE(Defect class)
    QPAM_SELSET_CODE_CREATE contains fields  KATALOGART, WERKS,AUSWAHLMGE ,CODEGRUPPE,CODE which I need and While stand alone testing of this function module I am geting error as follows with the data filled :
    Runtime:        6.496 Microseconds
    Exception       WRONG_KEY
    Message ID:          QS                         Message number:           299

    QPAM_SELECTED_SET_CREATE contains KATALOGART , WERKS,AUSWAHLMGE , KTX01 which I need and it requires Language key fiels KSP01. I specified it it executes successfully but in transaction it is not there. some FMs contain some fields and not all fields so I want to know which one to use ? Can anyone give me sample code how to use these FMs?

    Note 381286 - Code grps + selectd sets:Transport request requestd
    Note 592418 - Composite SAP note: Transport of code groups and codes
    But I do not recommend a modification because the system does not generate request for that in the production system.
    This means you can maintain catalog directly without transport in the production system.
    Only development or test system ask you a request number.

  • Passing SELECT-OPTIONS value to Function Module

    Hi,
    I need to pass select-options value to a function module.
    Code is like the following:
    SELECT-OPTIONS seltab FOR object-type.
    CALL FUNCTION 'Z_MY_FM'
          EXPORTING
            sel_tab         = seltab
         IMPORTING
            result_tab     = it_result
    I have found a similar problem in the SDN forum: How to pass select-options parameter to FM?
    However, that could not help me much in solving my problem.
    So far I have tried to created a structure in DDIC with the following components for the select-options:
    SIGN - BAPISIGN
    OPTION - BAPIOPTION
    LOW - ZBWOBJECTTYPE (my type)
    HIGH - ZBWOBJECTTYPE (my type)
    and subsequently a table type for this structure which is specified in the "Import" tab of my function module.
    Unfortunately, when I ran the program a runtime exception occured (CALL_FUNCTION_CONFLICT_TYPE).
    Could anyone please help me on this issue?
    Thanks in advance.
    Regards,
    Joon Meng

    Hello Joon,
    CALL FUNCTION 'Z_MY_FM'
          EXPORTING
            sel_tab         = seltab
         IMPORTING
            result_tab     = it_result
    You have defined SELTAB as a SELECT-OPTION.
    So when you pass only SELTAB, the header line is transferred to the FM. When you pass SELTAB[] the whole table(range) is passed.
    It is similar to the concept of an internal table with header line.
    Hope i am clear.
    Anyways how have you defined result_tab and sel_tab ?

    I have given a similiar example which i did
    Declare a
    Table type:Z_TT_PONUM             
    Short text  :  Select options  PO Number
    in SE11 tcode with row type eg: Z_ST_PONUM
    create a structure (this will be the row type)
    Structure          Z_ST_PONUM            
    Short text         Select Options Field PO number
    Compenent  Compent type
    SIGN       BAPISIGN      Inclusion/exclusion criterion SIGN for range tables
    OPTION       BAPIOPTION      Selection operator OPTION for range tables
    LOW       EBELN                      Purchasing Document Number
    HIGH       EBELN                      Purchasing Document Number
    In the function module import
    give as
    I_PO_NUM     TYPE     Z_TT_PONUM     opt  pass value Select options  PO Number
    Hope this is exactly what you want to know.
    So you create a structure simliar to mine but the low an high whould be your component
    then a table type  and then include that in the BAPI.
    Then pass your select-option value to this BAPI when you call this BAPI in the program

  • What is the difference using start condition and check function module

    what is the difference  between using start condition and check function module

    That's new to me, I thought a start condition was evaluated before the workflow started, and thus now workflow work item is available. That's why I think the only situation in which start conditions/check functions can't be used, is when the availability of a workflow log for investigation of exactly what stopped the workflow is a requirement.
    I suppose the <a href="http://help.sap.com/saphelp_46c/helpdata/en/4c/86bf43feca11d2a64f0060087a79ea/frameset.htm">SAP documentation</a> is in need of an update.

  • Select Options to RFC function modules

    Hi all
    When we use a PERFORM in main program, we can simply use the select-options
    as for ex.,
    in so_matnr
    in so_bsart
    like that
    without passing any parameters.
    This way it will take all values given in 'Single values' in the multiple selection option of selection screen.
    We need not bother about so_matnr-low and so_matnr-high.
    When we use a function module to be executed in another R/3 server ,
    we have to pass values. In these values we can pass so_matnr-low and so_matnr-high only. If the user selects Single Vals instead of these,
    how to pass them?
    Regards
    Vijaya Chamundi

    Hi,
    so_matnr is stored as a table, with fields sign, option, low and high.
    Each time you add a single value, a line is added to the table.
    If you add 'single value'  1 in the selection screen, then a line is added to table so_matnr[] with fields sign='I', option='EQ' and low='00000..1' and high is empty.
    So, if you want to pass it as a parameter, you can pass it as a table:
    so_matnr[]
    In this way you are sure you have all the information you need.
    regards,
    Rolf

    If the correct configuration allows for manual entry of the condition type you want to populate, You can map your value using
    ' ORDER_CONDITIONS_IN'  . If item level map line number, cond step number of the condition type in your pricing procedure, your condition type you are using,  condition value you are sending into the system,  currency, and cond unit. If it is a header condition, then send in 000000 as the item number.   You can also consider using BAPI_SALESORDER_CREATEFROMDAT2

  • How to pass select option value to function module while using service call

    Hi,
    I have select-option in my WD application. To collect data based on user input im using service call. How to pass this select option values to my RFC.
    rgds
    sudhanshu

    Hi,
    Thank s for your reply. In fact im doing similar with following variation:
    i) collected range values using get_range* method.
    ii) separate low and high values as: 
    read table <field2> index 1 into wa_range.
    vert2_low = wa_range-low.
    vert2_high = wa_range-high.
    (Please note that in RFC I have taken two importing parameter as s_vert_lo and s_vert_hi)
    iii) Now setting these RFC attribute as:
    lo_el_importing->set_attribute(
        EXPORTING
          name =  `S_VERT_LO`
          value = vert2_low ).
    and
    lo_el_importing->set_attribute(
        EXPORTING
          name =  `S_VERT_HI`
          value = vert2_high ).
    iv) In RFC im having my query as :
    select <fld list> from BUT000 into table itab where vertical in r_vert.
    Here, r_vert is a range defined as:
    ranges r_vert for <fld refrence>
    r_vert-sign = 'I'.
    r_vert-option = 'BT'.
    r_vert-low = S_VERT_LO.
    r_vert-high = S_VERT_HI.
    append r_vert.
    Issue here is with ranges. if im passing both low and high values it is fine but if only low value being passed it is not giving me any record.
    Please suggest.

  • Exceptions in Function Modules

    Hi
    How can I create an Exception in a Function Module and Raise that based on some condition? Plz help

    Hi Santo,,,,
    Look into this link ,, where u will get  a clear information on exceptions,,,,,

    In the function module, you can create your own local types and data objects, and call subroutines or other function modules.
    You can make a function module trigger exceptions .
    To do this, you must first declare the exceptions in the interface definition, that is, assign each one a different name.
    In the source code of your function module, you program the statements that trigger an exception under the required condition. At runtime, the function module is terminated when an exception is triggered.
    The changes to exporting and changing parameters are the same as in subroutines. There are two statements that you can use to trigger an exception. In the forms given below, stands for the name of an exception that you declared in the interface. The system reacts differently according to whether or not the exception was listed in the function module call:
    RAISE .
    If the exception is listed in the calling program, the system returns control to it directly. If the exception is not listed, a runtime error occurs.
    MESSAGE () RAISING .
    If the exception is listed in the calling program, the statement has the same effect as RAISE . If it is not listed, the system sends message from message class with type , and no runtime error occurs.
    Function modules differ from subroutines in that you must assume that they will be used by other programmers. For this reason, you should ensure that you complete the steps listed here.
    Documentation (can be translated)
    You should document both your parameters and exceptions with short texts (and long texts if necessary) and your entire function module. The system provides a text editor for you to do this, containing predefined sections for Functionality, Example Call, Hints, and Further Information.
    Work list
    When you change an active function module, it acquires the status active (revised). When you save it, another version is created with the status inactive . When you are working on a function module, you can switch between the inactive version and the last version that you activated. When you activate the inactive version, the previous active version is overwritten.
    Function test
    Once you have activated your function module, you can test it using the built-in test environment in the Function Builder. If an exception is triggered, the test environment displays it, along with any message that you may have specified for it. You can also switch into the Debugger and the Runtime Analysis tool. You can save test data and compare sets of results.
    When you insert a function module call in your program, you should use the Pattern function. Then, you only need to enter the name of the function module (input help is available). The system then inserts the call and the exception handling (MESSAGE statement) into your program.
    You assign parameters by name. The formal parameters are always on the left-hand side of the expressions:
    Exporting parameters are passed by the program. If a parameter is optional, you do not need to pass it. Default values are displayed if they exist.
    Importing parameters are received by the program. All importing parameters are optional.
    Changing parameters are both passed and received. You do not have to list optional parameters.
    Default values are displayed if they exist.
    The system assigns a value to each exception, beginning at one, and continuing to number them sequentially in the order they are declared in the function module definition. You can assign a value to all other exceptions that you have not specifically listed using the special exception OTHERS.
    If you list the exceptions and one is triggered in the function module, the corresponding value is placed in the return code field sy-subrc. If you did not list the exception in the function call, a runtime error or a message occurs, depending on the statement you used in the function module to trigger the exception.
    When you create a function module, you must assign it to a function group. The function group is the main program in which a function module is embedded.
    A function group is a program with type F, and is not executable . The entire function group is loaded in a program the first time that you call a function module that belongs to it.
    The system also triggers the LOAD-OF-PROGRAM event for the function group.
    The function group remains active in the background until the end of the calling program. It is therefore a suitable means of retaining data objects for the entire duration of a program. All of the function modules in a group can access the group's global data.
