Field symbol as import parameter in class method ???

Hi everyone,
is it possible to pass a field symbol as an import parameter to a method in a class? If yes, how do I define the data type of the import parameter? I'm trying to work with field symbols as the program doesn't know what kind of structure the program parameter p_srcdso has. Coding example would be something like this:
PARAMETERS: p_srcdso TYPE rsdodsobject DEFAULT '/BIC/AKVI0001'.
DATA: lr_srcpkg TYPE REF TO data.
FIELD-SYMBOLS: <fs_table> TYPE ANY TABLE.
CREATE DATA lr_srcpkg TYPE TABLE OF (p_srcdso).
ASSIGN lr_srcpkg->* TO <fs_table>.
SELECT *
FROM (p_srcdso)
INTO TABLE <fs_table>.
CALL METHOD cl_ref->create_somethign
EXPORTING
i_source_package = <fs_table>.
Thanks,
Alex

Halo Alexander,
You can use TYPE REF TO DATA( say the parameter name is i_data) as the importing parameter of the method create_somethign and inside the method you need to dereference it using data reference variable again.
data: dref type ref to data.
field-symbols: <fs_table> type table.
create data dref like i_data.
assign dref->* to <fs_table>.

Using field symbol on export parameter

HI All,
I am using this logic In few methods of mine and I wonder if there is option the create one method
and every time that I need it just call it.
The issue is that <lt_output> is not assign yet (this need to happen in the method itself )so And I need to export it
and if I am creating method with exporting field type any I put the field symbol there I am getting dump.
Any idea ?
ASSIGN COMPONENT lv_table_out
 OF STRUCTURE is_response TO <lt_output>.
IF sy-subrc <> 0.
 READ TABLE it_map INTO ls_map INDEX 1.
 lv_out = ls_map-left.
 ASSIGN COMPONENT lv_out
 OF STRUCTURE is_response TO <lt_output>.
ENDIF.
Best regards
Joy

Hi,
Ok, then you will have to use a data object to reference your field symbol and use a returning parameter I guess:
DATA: lo_data TYPE REF TO data.
FIELD-SYMBOLS: <lt_output> TYPE ANY.
CLASS lcl_main DEFINITION.
PUBLIC SECTION.
 CLASS-METHODS: get RETURNING value(r_val) TYPE REF TO data.
ENDCLASS.
CLASS lcl_main IMPLEMENTATION.
METHOD get.
 FIELD-SYMBOLS <fs> TYPE ANY.
 ASSIGN COMPONENT 1 OF STRUCTURE is_response TO <fs>.
 GET REFERENCE OF <fs> INTO r_val.
ENDMETHOD. "get
ENDCLASS.
START-OF-SELECTION.
lo_data = lcl_main=>get( ).
ASSIGN lo_data->* TO <lt_output>.

Missing Parameter in class method

Hi,
This is with regard to the Survey transaction. For survey, I did some modifications and I did the modifications based on a parameter in class method CL_UWS_PUBLISHING=>PUBLISH. It was working fine in our development server. But when I ported it to the Quality system, an erro appears telling that the parameter ID_SURVEY_ID is not available in the system.
As part of the implementation, our team has applied several notes to the application. Is it that, this parameter came as part of some note? If so, how can I find the relevant note. I searched for notes regarding survey but didn't find this one.
Please do help me in this regard.

Declaring Field Symbols in Public Section of class

Dear All,
I am working with class and hav declared some field symbols in one of the method.
Now I want to move these declaration in Public section of the class so that this field symbol declaration can be used by other methods of the class but I am not able to do the same.
Can anyone help me in finding as what I am doing wrong here.
Regards,
Lalit Kabra

What you are trying to do is define an attribute. I doubt you can use field symbol as a class attribute. Consider using a data object instead.
Data : dref type ref to data.
This can later be deferenced in the individual methods.
Hope this helps.
Here's an example for the same:
REPORT z_class_001 .
* CLASS lcl_class1 DEFINITION
CLASS lcl_class1 DEFINITION.
PUBLIC SECTION.
 DATA dref TYPE REF TO data.
 METHODS : constructor IMPORTING i_type TYPE char20,
 meth1 IMPORTING value TYPE i.
ENDCLASS. "lcl_class1 DEFINITION
* CLASS lcl_class1 IMPLEMENTATION
CLASS lcl_class1 IMPLEMENTATION.
METHOD constructor.
 CREATE DATA dref TYPE (i_type).
ENDMETHOD. "constructor
METHOD meth1.
 FIELD-SYMBOLS <fs> TYPE ANY.
 ASSIGN dref->* TO <fs>.
 WRITE: 'Value is ' ,value.
 ASSIGN value TO <fs>.
 WRITE: 'Field symbol is ', <fs>.
ENDMETHOD. "meth1
ENDCLASS. "lcl_class1 IMPLEMENTATION
START-OF-SELECTION.
DATA ref_class TYPE REF TO lcl_class1.
CREATE OBJECT ref_class EXPORTING i_type = 'I'.
CALL METHOD ref_class->meth1
 EXPORTING
 value = 3.

Problem with retrieving a value from the import parameter of a method

Hi Friends,
I have a problem accessing the field.
I have a import paramter in the method of my Z class. The import paramter is of type ANY.
In my method I get the value of this import paramter as
. In this I have a field Catalog Id which is a z field.
How should I retrieve the value of this catalog Id from this importing parameter?

Hi Friends
Can anyone tell me whether this is a structure or a Class refernce, so that I can access the field in that.

Field-symbols as parameters to the method of a class

Hi All,
I am having an doubt regarding the field-symbols.Can we pass the field-symbols as a parameter to the method of a class.If yes can anyone tell me how to do this. Before posting I have searched regarding it in google but I did not find any better solution.Though I have seen some examples regarding the passing of field symbols as a parameter those scenarios does not match with my report as my report varies dynamically based on selection criteria.
Below is the snippet of my code regarding the passing of field-symbols as a parameter.
methods: final_data importing <fs_h_line>TYPE any
 <fs_h> TYPE STANDARD TABLE
 exporting <fs_f_line> TYPE any
 <fs_f> TYPE STANDARD TABLE,
CALL METHOD l_obj->final_data exporting <fs_h_line> = <fs_header_line>
 <fs_h> = <fs_header>
 importing <fs_f_line> = <fs_final_line>
 <fs_f> = <fs_final>.
With the above code I am getting an error.Check whether it is correct or not.If not suggest the solution to resolve the issue.
Regards,
Chakradhar.

Hi
Maybe if you change this code below to field-symbol, it can work:

Passing unassigned field symbols to a method

Hello Gurus,
I work with a field symbol in a method and after the work is finished i have to use it i my program that i call the method from.
The problem is that the field symbol gets assigned only in the method so i can`t get the field symbol as a changing parameter in my method because it is not assigned yet.
I thought that i can return the field symbol from the method after it has been assigned, but i don`t know how. The <fs> is a dynamic itab that i created within the method.
Can anyone help please ??

Although already answered this code snippet might make it clearer
my_line is your data structure typically an itab structure.
For example
TYPES: BEGIN OF s_elements,
 tabname type DD02L-tabname,
 tabclass type dd02l-tabclass,
 as4user type dd02L-as4user,
 as4date type dd02l-as4date,
 as4time type DD02l-as4time,
 viewed(1) type c.
TYPES: END OF s_elements.
Data: my_line TYPE s_elements.
1) get the structure of your itab automatically so you can build an FCAT simply for any structure without the horrendous usual coding to manipulate and create FCATS.
CALL METHOD me->return_structure
 EXPORTING
 my_line = my_line.
You need to make a table ZOGT data available in the class definition either as an attribute if you are using the class builder SE24 or as DATA in the relevant class section.
data:
 zog LIKE LINE OF lr_rtti_struc->components .
data:
zogt LIKE TABLE OF zog .
method RETURN_STRUCTURE.
lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data( my_line ).
 zogt[] = lr_rtti_struc->components.
endmethod.
Your structure details are now in table zogt.
Use this to build an FCAT.
CALL METHOD me->create_dynamic_fcat
 IMPORTING
 it_fldcat = it_fldcat.
method CREATE_DYNAMIC_FCAT.
LOOP AT zogt INTO zog.
 CLEAR wa_it_fldcat.
 wa_it_fldcat-fieldname = zog-name .
 wa_it_fldcat-datatype = zog-type_kind.
 wa_it_fldcat-inttype = zog-type_kind.
 wa_it_fldcat-intlen = zog-length.
 wa_it_fldcat-decimals = zog-decimals.
 wa_it_fldcat-coltext = zog-name.
 wa_it_fldcat-lowercase = 'X'.
 APPEND wa_it_fldcat TO it_fldcat .
 ENDLOOP.
endmethod.
Now having got your FCAT you can build your dynamic table.
 CALL METHOD me->create_dynamic_table
 EXPORTING
 it_fldcat = it_fldcat
 IMPORTING
 dy_table = dy_table.
(dy_table is defined as ref to data)
method CREATE_DYNAMIC_TABLE.
CALL METHOD cl_alv_table_create=>create_dynamic_table
 EXPORTING
 it_fieldcatalog = it_fldcat
 IMPORTING
 ep_table = dy_table.
endmethod.
Now populate your dynamic table as per sample code here
field_symbols:
<dyn_table> TYPE STANDARD TABLE.
<dyn_wa>.
data: dy_line TYPE REF TO data.
FORM populate_dynamic_itab.
ASSIGN dy_table->* TO <dyn_table>.
 CREATE DATA dy_line LIKE LINE OF <dyn_table>.
ASSIGN dy_line->* TO <dyn_wa>.
SELECT *
 FROM DD02L
 INTO CORRESPONDING FIELDS OF TABLE <dyn_table>
 WHERE TABNAME LIKE 'ZHR%'.
ENDFORM.
Now you can display your grid and process your data.
CALL METHOD z_object->display_grid
 EXPORTING
 g_outtab = <dyn_table>
 g_fldcat = it_fldcat
 i_gridtitle = i_gridtitle
 i_edit = i_edit
 i_zebra = i_zebra
 CHANGING
 it_fldcat = it_fldcat
 gt_outtab = <dyn_table>.
In the Method
method DISPLAY_GRID.
GET REFERENCE OF g_outtab INTO g_outtab1.
 GET REFERENCE OF g_fldcat INTO g_fldcat1.
 struct_grid_lset-edit = i_edit. "To enable editing
 struct_grid_LSET-zebra = i_zebra.
 struct_grid_lset-grid_title = i_gridtitle.
 struct_grid_lset-ctab_fname = 'T_CELLCOLORS'.
 struct_grid_lset-stylefname = 'CELLTAB'.
 CALL METHOD grid1->set_ready_for_input
 EXPORTING
 i_ready_for_input = '1'.
 CALL METHOD grid1->set_table_for_first_display
 EXPORTING
 is_layout = struct_grid_lset
 CHANGING
 it_outtab = gt_outtab
 it_fieldcatalog = it_fldcat.
ENDMETHOD.
You can even easily code your own column names if you so wish in the application program.
Before calling the method that displays the grid encode the following macro.
DEFINE col_name.
read table it_fldcat into wa_it_fldcat index &1.
wa_it_fldcat-coltext = &2.
wa_it_fldcat-outputlen = &3.
modify it_fldcat from wa_it_fldcat index &1.
END-OF-DEFINITION.
Then have a subroutine in your application code something like this
Form name_columns.
Here before displaying you can change the field catalog to
adjust your own column names.
*col_name col-nr 'your name' output length.
 col_name 1 'Table name' 30.
 col_name 2 'Table class' 12.
 col_name 3 'Changed By' 12.
 col_name 4 ' On' 12.
 col_name 5 ' At' 8.
 col_name 6 'Act' 3.
i_gridtitle = 'HR ESS / ITS ZHR Tables - Double click to display'.
i_zebra = 'X'.
i_edit = ' '.
endform.
Hope this clears it up a bit.
Once you get this stuff working you can re-use 99% of the code for almost any structure making the whole process of OO ALV grid applications really simple.
Yoy only need as well a standard dynpro with a custom container on it (se51).

HOW TO PASS SELECT-OPTIONS AS IMPORT PARAMETER TO A CLASS

Hi experts,how to pass select options value as a export parameters to a zclass.
can give me some idea.
Thanks
sai

As Sachin already said, selection options are stored in an internal table. You can reconstruct the table type without the corresponding input fields using the type addition RANGE OF.
So - assuming you have the following in your program:
DATA: wa TYPE sflight.
SELECT-OPTIONS so_car FOR sflight-carrid.
you can create a publically-visible type in your class using direct type entry and the code
TYPES: my_selectoption TYPE RANGE OF sflight-carrid.
and use this to define the importing parameter of the method.
The only other thing you have to remember is that select-options generates an internal table with header line. Thereore, to pass the table to the method, you would use (in the above example) so_car[], and not just the name of the select-option.
Hope this helps.

How to give a value range in export parameter (global class)

hi all,
I have created a class-method called get_po_date. In this i had export parameter as qmfe-qmnum. If i give qmfe-qmnum in import parameter in class, i am able to give only one value at one time, but i need a range of values at a time. Instead of qmfe-qmnum in associated type, i have given 'LXHME_RANGE_C12' ( a range table for char 12 ). the thing is i wanted to select this range in select-options. but still iam getting not type compatible syntax error. can any body solve my problem,
feel free to ask if any confusion with my question.
Best Regards,
abhilash.

Hello Abhilash
Instead of using a specific range (where field LOW and HIGH are of type QMNUM) you can use a generic select option (of type RSDSSELOPT). Have a look at the following sample report ZUS_SDN_SELOPTIONS.
*& Report ZUS_SDN_SELOPTIONS
REPORT zus_sdn_seloptions.
TABLES: qmfe.
DATA:
gt_data TYPE STANDARD TABLE OF qmfe,
gt_data_x TYPE STANDARD TABLE OF qmfe,
gt_selopt TYPE rseloption, " generic table type for selopts
gs_selopt TYPE rsdsselopt.
START-OF-SELECTION.
SELECT * FROM qmfe INTO TABLE gt_data
 WHERE ( qmnum BETWEEN '000000000001' AND '000000000500' ).
gs_selopt-sign = 'I'.
gs_selopt-option = 'BT'.
gs_selopt-low = '000000000001'.
gs_selopt-high = '000000000500'.
APPEND gs_selopt TO gt_selopt.
SELECT * FROM qmfe INTO TABLE gt_data_x
 WHERE ( qmnum IN gt_selopt ).
IF ( gt_data = gt_data_x ).
 WRITE: 'Selected data are equal.'.
ELSE.
 WRITE: 'Selected data are NOT equal.'.
ENDIF.
END-OF-SELECTION.
Since RSDSSELOPT and RSELOPTION are global DDIC objects they can be used in public methods.

Field symbols in ...........in SE24....have ur points..pleas

Hi all,
I want to declare a field symbol <fs> in a class, & to use it in different methods of the same class.
But in attributes of the class, how i declare field symbol in a class.
I m not able to do this...
Pleas assist me..& have ur points.

pradeep phogat

Pradeep,
See this thread. It gives details about field symbol used in a standard class. This should give you some idea.

How to change column name heading thru Class method in ALV report

When I Select LayOut on Selection screen then Display ALV Output columnname display Quantity but I want change this name to Carats.
I set Short, Medium and Long text is Carats.

DATA: lt_fcat type lvc_t_fcat,
 lv_fname type fieldname value '<Your FName>'.
FIELD-SYMBOLS: <fcat> type lvc_s_fcat.
CALL METHOD alv_grid->get_frontend_fieldcatalog
 IMPORTING
 et_fieldcatalog = lt_fcat.
read table lt_fcat assigning <fcat> with key fieldname = lv_fname.
if sy-subrc is initial.
 <fcat>-COLTEXT = <fcat>-SCRTEXT_L = <fcat>-SCRTEXT_M = <fcat>-SCRTEXT_S = <fcat>-SELTEXT = '<Your new Description>'.
endif.
CALL METHOD alv_grid->set_frontend_fieldcatalog
 EXPORTING
 it_fieldcatalog = lt_fcat.
call method alv_grid->REFRESH_TABLE_DISPLAY.

Problem with import parameter

Our GetDetail function has an import parameter that we need to use to filter the returned dataset. The parameter, MTRANTY, shows up correctly in the "Import" section of our GetDetail in the Mapping Screen of merep_sbuilder. What I am not seeing is any reference to MTRANTY in the generated meRepMeta.xml file. In the "Import" section of the mapping screen is does show "Link to Key Field of TOP: MTRANTY" in the Mapping Description.
When I bring up the filtering criteria of our syncbo it shows another field, CUSTOMER, as "Filter Field 1", but I can't seem to be able to change it to MTRANTY as I think it should be.
So, my question is, do the filter field and the import parameter have any connection? Is there something else I need to do to make MTRANTY available in the meRepMeta.xml definition? Or do I just set the key field of TOP (SYNC_KEY from the xml file) to my desired value and perform the synchronization?
On a related note, in the xml file on the "SyncBO id" line, the parameter "reqDirectSync" is set to false. Will this prevent me from initiating a synchronization using SyncManager.synchronizeWithBackend()?
Thanks,
Adam

Hi Adam,
The main thing here are ,
1)Metadata definition (XML file: Client view of SyncBO)
(meRepMeta.xml )
The data structure used for the data exchange between the mobile clients and the MI Server Component can be specified by defining the metadata for the SyncBO.
This XML document will be used by the MI JAVA APIs to access and manipulate the local SyncBO data downloaded from Smart Synchronization.
A client application developer typically looks into the generated XML document for implementing the data access layer of a client application.
2)Default value setting
It might not be necessary to expose some fields to the clients; how ever, the fields can be mandatory fields when the BAPI wrappers are called (mainly in create and change functions). In such cases, the field can be set as default and its default value can be assigned. The default values also need to be assigned for the selection criteria parameter(s) of the GetList BAPI
wrapper function, which is used to pre-filter data being stored in the replica database.
3)Filter setting
To reduce the number of records on client devices, for example, to avoid downloading unnecessary data, the data filtering function can be used to filter the data downloaded from the replica database.
Filtering is possible on these levels:
a)At SyncBO level
b)At Mobile ID level
c) Mobile group Level.
 During synchronization,
associated with each sync bo ...
Getlist populate the Header Instances.
-- for each Header instance getdetail is executed.
so in the importing mapping part ,
the mapped fields are only necessary for the server at runtime.(here u can create value ids corresponding to each importing parameter and set values .)
if u want to filter the header instances by means of user who is syncing .. then u ca directly give the default value of Value ID as ME-SYNC_USER against ur importing parameter.
[In the client we need only the header details and item details only].
 The relation bw filtering of ITEM (Getdetail) is maintained through the key fields in the ImportParam of Getdetail.(which are internally linked through the Header populated in Getlist ..)
(Key fields of Getlist is a subset of fields in the Header Structure).
<<So, my question is, do the filter field and the import parameter have any connection? >>
As i mentioned above , Getlist is executed using the import params , and the replica BD is populated with the output from getList. Filters filter data from Replica DB to the Client Device...
