At end of field, for dynamic internal table entries ?

Dear All,
I've data in my dynamic internal table.
But, to understand in a better way I created a test program with static entries.
Case 1 -->
DATA: BEGIN OF itab OCCURS 0,
        year TYPE char4,
        name TYPE char10,
      END OF itab.
DATA: BEGIN OF itab2 OCCURS 0 ,
        year TYPE char4,
        name TYPE char10,
        count TYPE i,
      END OF itab2.
DATA: gv_count TYPE i,
      gv_flag TYPE char1.
itab-name = 'AAAA'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAB'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAC'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'AAAD'.
itab-year = '2008'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBB'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBA'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBC'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'BBBD'.
itab-year = '2007'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCC'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCA'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCB'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCD'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCE'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'CCCf'.
itab-year = '2006'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDD'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDA'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDB'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDC'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
itab-name = 'DDDE'.
itab-year = '2005'.
APPEND itab.
CLEAR itab.
SORT itab BY year.
LOOP AT itab.
* Counter
gv_count = gv_count + 1.
AT END OF year.
    itab2-count = gv_count.
    MOVE-CORRESPONDING itab TO itab2.
    APPEND itab2.
    CLEAR gv_count.
    WRITE:/ itab2-name,
    itab2-year,
    itab2-count.
    CLEAR itab2.
    CLEAR gv_flag.
ENDAT.
ENDLOOP.
Now for the above program the Output is :
Name     Year          Count
********** 2005          5
********** 2006          6
********** 2007          4
********** 2008          4
" Forget about the asterisk values as it's an example !
The above output is correct, But in my real case the table structure is not like the above .
The order of the field are in reverse.
i.e. The internal table is like this :
Case 2 -->
DATA: BEGIN OF itab OCCURS 0,
        name TYPE char10,
        year TYPE char4,
      END OF itab.
DATA: BEGIN OF itab2 OCCURS 0 ,
        name TYPE char10,
        year TYPE char4,
        count TYPE i,
      END OF itab2.
In this case if I'm using at end of year the output is coming wrong.
Even on change of is also not working.
Request you guys to help me out so that I can achieve the same output as of case 1 with the table declaration as of CASE 2.

Hello Rich Heilman,
Again you came for my rescue ............
My code for this scenario is like this :

Use this code to get all components of internal table.
Then build fieldcatlog.
DATA: tab_return type abap_compdescr_tab,
          components like line of tab_return.
perform get_int_table_fields using    <fs_it> changing tab_return.
loop at tab_return into components.

Should I remove the T_CELLTAB as the field name is not mentioned in the structure 'ZCELLTAB'.

To create a deep structure for dynamic internal table.

Hello
My ALV has fields which are defined dynamically during execution.
so, i did it in the following way,
Declared Field symbolds, DREF and fieldcatalog as,
FIELD-SYMBOLS: <t_dyntable> TYPE STANDARD TABLE,
              <fs_dyntable>.
DATA:   dref_dyntab    TYPE REF TO data,
        dref_dynwa     TYPE REF TO data.
DATA: ts_fieldcatalog TYPE lvc_t_fcat.
DATA: wa_fieldcatalog TYPE lvc_s_fcat.
Updated Fieldcatalog dynamically as,
*function module to read segment structure
    CALL FUNCTION 'SEGMENT_READ'
      EXPORTING
        segmenttyp           = v_segment_name
      TABLES
        segmentstructure     = ts_seg_structure
      EXCEPTIONS
        no_authority         = 1
        segment_not_existing = 2
        OTHERS               = 3.
    IF sy-subrc <> 0.
      CASE sy-subrc.
        WHEN '1'.
          MESSAGE e024.
          STOP.
        WHEN '2'.
          MESSAGE e025 WITH v_segment_name.
          STOP.
        WHEN OTHERS.
          MESSAGE e023.
      ENDCASE.
    ENDIF.
*FETCH FIELDS FROM STRUCTURE OF SEGMENT AND CREATE FIELDCATALOG FOR
EACH FIELD OF SEGMENT (DYNAMIC FIELD CATALOG)
    LOOP AT ts_seg_structure INTO wa_seg_structure.
      ADD 1 TO v_counter.
      wa_fieldcatalog-fieldname = wa_seg_structure-fieldname.
      wa_fieldcatalog-col_pos   = v_counter.
      wa_fieldcatalog-ref_table = wa_seg_structure-segtyp.
      APPEND wa_fieldcatalog TO ts_fieldcatalog.
      CLEAR wa_fieldcatalog.
    ENDLOOP.
and generated dynamic internal table using fieldcatalog as,
*--Method to get the structure of table using fieldcatalog.
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = ts_fieldcatalog
    IMPORTING
*--Variable of type REF TO DATA.

*--Dynamic internal tables required when show segments selected

*--Create dynamic work area and assign to FS
CREATE DATA dref_dynwa LIKE LINE OF <t_dyntable>.
    ASSIGN dref_dynwa->* TO <fs_dyntable>.
And then i populated this <t_dyntable> which is being passed as data-table to method
CL_GUI_ALV_GRID => SET_TABLE_FOR_FIRST_DISPLAY
for ALV grid Display along with above used filedcatalog ts_fieldcatalog.
Things are fine till here, but now i have the requirement to edit selected rows of the ALV display..
As you might be aware, we need a field
        TS_STYLEROW TYPE lvc_t_styl, (i.e, a field of type 'h' and we can say as an internal table inside an internal table or else as a deep structure)
in the output internal table <t_dyntable> to meet our requirement.
My issue is about declaring one such field of type 'h' in this dynamically created internal table ''<t_dyntable>".
I tried in the following way by adding one such field to fieldcatalog :
*Field for Styling
ADD 1 TO v_counter.
wa_fieldcatalog-fieldname   = 'TS_STYLEROW'.
wa_fieldcatalog-tabname     = 'TS_STYLE'.
wa_fieldcatalog-col_pos     = v_counter.
wa_fieldcatalog-no_out      = 'X'.
wa_fieldcatalog-inttype     = 'h'.      " I even mentioned this
APPEND wa_fieldcatalog TO ts_fieldcatalog.
CLEAR wa_fieldcatalog.
But this is creating a field of type 'C' in the table <t_dyntable> instead of what i was expecting
Guyz and respected,
Please advice me with the solution or ur ideas....
Note : The overall requirement is create a deep structure for dynamically generated internal table.
Your help is highly appreciated and unforgettable..!!!!!!!

Hi Avinash,
Either use parameter
I_STRUCTURE_NAME = W_TABNAME
or
IT_FIELDCATALOG = LT_FIELDCATALOG2
Both are not required.
At the end of ur program simply use a write statement like below. Your program will work.
IF SY-SUBRC 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
Write /.      <----

Usage of 'Select for all entries' for dynamic internal tables..

Hi all,
I have a situation where I need to use select for all entries for a dynamic internal table.
select * from /BIC/AZHSD_O1500 into i_table for all entries in <b>Dynamic_table</b> where doc_number = <dynamic_table????????>
here iam not knowing how to match the <dynamic_table????????> doc_number ?
the dynamic_table contains the doc_number as one field.
here dynaimc_table is the internal table which is dynamic.
I have tried various options but couldnot find the solution.
Please resolve.
Sidhartha.

data : i_dyn_where type char72 occurs 0.
field-symbols : <fs> type table.
assign itab[] to <fs>.
i_dyn_where = 'docno = <fs>-docno'.
append i_dyn_where.
select *
from   vbak
into   table t_vbak
for    all entries in <fs>
where (I_dyn_where).   "Populate this where condition dynamically too
Hope this will solve ur prob.

Splitting a string into respective fields of dynamic internal table

Hi,
    I've a string concatenated with a separator. I've to split the string and assign it to the respective fields of an internal table, which is dynamic.
Table name will be passed through selection screen. The data is coming from another system via RFC.
Eg : String ITAB :
                            100;89001;EN;Material1;MATERIAL1
                            100;89002;EN;Material2;MATERIAL2
The String ITAB may contain any master data. Let's say the above data is from MAKT table. So, I want to assign the above data to the respective fields of MAKT internal table(Dynamic).
I heard, this requirement can be achieved using some standard CLASS.
Please help me in doing this task.
Regards,
Sunny

Hello,
you can use dynamic programming for this issue, i.e.:
DATA: gv_table_name   TYPE string,
      gr_type_desc    TYPE REF TO cl_abap_typedescr,
      gr_struct_desc TYPE REF TO cl_abap_structdescr,
      gr_table_desc   TYPE REF TO cl_abap_tabledescr,
      gv_t            TYPE c,
      gv_comp         TYPE i,
      gr_table_ref    TYPE REF TO data,
      gr_struc_ref   TYPE REF TO data.
DATA: gt_itab   TYPE TABLE OF string,
      gt_split TYPE TABLE OF string,
      gv_str    TYPE string.
FIELD-SYMBOLS: <table>    TYPE ANY TABLE,
               <struct>   TYPE ANY,
               <comp>     TYPE ANY.
APPEND '100;89001;EN;Material1;MATERIAL1' TO gt_itab.
APPEND '100;89002;EN;Material2;MATERIAL2' TO gt_itab.
"go!
gv_table_name = 'MAKT'.
cl_abap_tabledescr=>describe_by_name(
      EXPORTING p_name = gv_table_name
      RECEIVING p_descr_ref = gr_type_desc
      EXCEPTIONS type_not_found = 4 ).
gr_struct_desc ?= gr_type_desc.
gr_table_desc = cl_abap_tabledescr=>create( gr_struct_desc ).
CREATE DATA gr_table_ref TYPE HANDLE gr_table_desc.
CREATE DATA gr_struc_ref TYPE HANDLE gr_struct_desc.
ASSIGN gr_table_ref->* TO <table>.
ASSIGN gr_struc_ref->* TO <struct>.
DESCRIBE FIELD <struct> TYPE gv_t COMPONENTS gv_comp.
LOOP AT gt_itab INTO gv_str.
CLEAR: gt_split.
SPLIT gv_str AT ';' INTO TABLE gt_split.
DO gv_comp TIMES.
    READ TABLE gt_split INTO gv_str INDEX sy-index.
    ASSIGN COMPONENT sy-index OF STRUCTURE <struct> TO <comp>.
    <comp> = gv_str.
    CLEAR gv_str.
ENDDO.
INSERT <struct> INTO TABLE <table>.
ENDLOOP.
After this code you will have all data in <table> field symbol in proper type.

Jacek

Field Texts for Dynamic Internal Tables

Hi All,
I want to know whether there is any way to get the field Headings (Not the field names)
Below is my CODE
For ex :
CLASS lvl_met DEFINITION.
   PUBLIC SECTION.
     METHODS : l_met IMPORTING m_itab TYPE STANDARD TABLE.
ENDCLASS.
CLASS lvl_met IMPLEMENTATION.
METHOD l_met.
data : l_t_fields TYPE abap_compdescr_tab." WITH HEADER LINE.
field-symbols:
    <p_data>      type any,
    <p_field>     type any,
    <p_component> type abap_compdescr.
CREATE DATA MY_WA LIKE LINE OF m_itab.
ASSIGN MY_WA->* TO <P_DATA>.
DESC_STRUC ?= CL_ABAP_TYPEDESCR=>DESCRIBE_BY_DATA( <P_DATA> ).
*I want the field Headings(Field Text) - In this case i want some thing like Material Number and Plant
I can read this texts if i know atleast the data element
At this point i see <p_data> in degbug mode under absolute type column i see \TYPE=WERKS_D aganst werks field
I don't know how to capture the \TYPE=WERKS_D this thing so atleast i can read field Text based on Data Element
Is there any other way to find out the field text
ENDCLASS.
TABLES : marc.
DATA : l_met TYPE REF TO lcl_met.
types : BEGIN OF t_itab,
matnr like marc-matnr,
werks like marc-werks,
end of t_itab.
data : itab type table of t_itab.
START-OF-SELECTION.
IF l_met IS INITIAL.
    CREATE OBJECT l_met.
ENDIF.
select matnr werks from marc into TABLE itab up to 10 rows.
l_met->get_headertext( EXPORTING m_itab = itab ).
Thanks
David

Hi Naimesh,
I tried exactly what you said
lt_comp = desc_struc->get_components( ). "Get the fields of the structure
loop at lt_comp into ls_comp.
lo_elem_desc ?= cl_abap_elemdescr=>describe_by_name( ls_comp-name ).
lf_dfies = lo_elem_desc->get_ddic_field( ).
WRITE: / lf_dfies-scrtext_s,
       / lf_dfies-scrtext_m,
       / lf_dfies-scrtext_l.
WRITE:/ ls_comp-name. " Write the column names
endloop.
It Works fine for Matnr because field name and data element are same but when it comes to werks it gives me a dump because the date element is different werks_d
I just tried hard coding werks_d and it works fine
lo_elem_desc ?= cl_abap_elemdescr=>describe_by_name( 'WERKS_D' ).
lf_dfies = lo_elem_desc->get_ddic_field( ).
WRITE: / lf_dfies-scrtext_s,
       / lf_dfies-scrtext_m,
       / lf_dfies-scrtext_l.
Let me know how
Thanks
David

Populating Empty Fields for Existing Internal Table Using For All Entries

I have an internal table called itab_extract that populates without any issues in SELECT A and SELECT B below. Trying to avoid looping, I am using select DB table 'for all entries' in itab_extract. I want the empty fields in itab_extract to populate from the values in the database. However, about 200,000 entries are being appended to the table, and, the values that existed for the already populated fields in itab_extract are gone, and the new fields are populated.
I've played with the syntax and cannot seem to get it to work. My next option is a time consuming loop.
How should the for all entries syntax look to accomplish filling the empty fields in the itab?   Thank-You
*read ekko
    select ebeln lifnr aedat bsart from ekko                                                     *SELECT A*
           into CORRESPONDING FIELDS OF TABLE me->itab_extract
           where aedat in r_aedat.
    select ebeln lifnr aedat BSART from ekko                                                  *SELECT B*
           appending CORRESPONDING FIELDS OF TABLE me->itab_extract
           where aedat in S_DATE2 AND
                 BSART IN S_BSART.
      select ebelp werks matnr                                                                           *SELECT C*
        into CORRESPONDING FIELDS OF TABLE itab_extract
        from ekpo
        FOR ALL ENTRIES IN itab_extract
        where ebeln = itab_extract-ebeln.

Hi Tom,
           This SQL statement will be time consuming, Do not use a loop.
There are two options.
1. Select EKKO and EKPO details based on standard SAP view. (You can type EKKO in se11 view to find the correct view).
    also use one range table populate r_aedat and s_date2 in the same. So you where condition will have r_newrange and
    s_bsart. Also do not use into corresponding fields, it is not a good idea. It will increase your performance. Maintain the proper
    sequence (Based on database structure of EKKO and EKPO)
2. If you are keen to use for all entries, then first select ekko then after your sy-subrc check get the data from EKPO.
Should be like this.
select ebeln bsart aedat lifnr from ekko into table gt_ekko where aedat in r_newrange and bsart in s_bsart.
if sy-subrc eq 0.
sort gt_ekko by ebeln ascending.
select ebeln ebelp werks matnr into table gt_ekpo for all entries in gt_ekko where ebeln eq gt_ekko-ebeln.
endif.
Hope it helps,
Best Regards,
Tapodipta Khan.

Dynamic Alv for Dynamic Internal Table

Hi All,
I am new for abap dynpro.
How can i create a dynamic alv table in abap dynpro withoud ddic structure??
My requirement is as follows:
I have a table having some field e.g MATNR WERKS NETWR.
I want to pivot data werks and to display in webdynpro alv.
Thnx:

You can use the RTTI to build up a dynamic structure in memory:

Filling dynamic internal table with data from other internal table

Hi Friends,
My problem is that i have already built a dynamic internal table
(class int_table->create) but now i want to fill it with data from other internal table.
The dynamic table column name and the field value of the data filled internal table are same, but how to access that column name, since i cant hard code it anyway.
Like if my werks field value is '8001'. I want to place it under the column 8001 of dynamic table, Can anybody help me in this regard?
Awarding points is not a problem for even giving a slight hint.
Best Regards

Hi
See this
Dynamic internal table is internal table that we create on the fly with flexible column numbers.
For sample code, please look at this code tutorial. Hopefully it can help you
Check this link:
http://www.****************/Tutorials/ABAP/DynamicInternaltable/DynamicInternalTable.htm
Sample code:
DATA: l_cnt(2) TYPE n,
l_cnt1(3) TYPE n,
l_nam(12),
l_con(18) TYPE c,
l_con1(18) TYPE c,
lf_mat TYPE matnr.
SORT it_bom_expl BY bom_comp bom_mat level.
CLEAR: l_cnt1, <fs_dyn_wa>.
Looping the component internal table
LOOP AT it_bom_expl INTO gf_it_bom_expl.
CLEAR: l_cnt1.
AT NEW bom_comp.
CLEAR: l_cnt, <fs_dyn_wa>, lf_mat.
For every new bom component the material data is moved to
temp material table which will be used for assigning the levels
checking the count
it_mat_temp[] = it_mat[].
Component data is been assigned to the field symbol which is checked
against the field of dynamic internal table and the value of the
component number is been passed to the dynamic internal table field
value.
ASSIGN COMPONENT c_comp_list OF STRUCTURE <fs_dyn_wa> TO
<fs_check>.
<fs_check> = gf_it_bom_expl-bom_comp.
ENDAT.
AT NEW bom_mat.
CLEAR l_con.
ENDAT.
lf_mat = gf_it_bom_expl-bom_mat.
Looping the temp internal table and looping the dynamic internal table
*by reading line by line into workarea, the materialxxn is been assigned
to field symbol which will be checked and used.
LOOP AT it_mat_temp.
l_nam = c_mat.
l_cnt1 = l_cnt1 + 1.
CONCATENATE l_nam l_cnt1 INTO l_nam.
LOOP AT <fs_dyn_table2> ASSIGNING <fs_dyn_wa2>.
ASSIGN COMPONENT l_nam OF STRUCTURE <fs_dyn_wa2> TO <fs_xy>.
ENDLOOP.
IF <fs_xy> = lf_mat.
CLEAR lf_mat.
l_con1 = l_con.
ENDIF.
Checking whether the material exists for a component and if so it is
been assigned to the field symbol which is checked against the field
of dynamic internal table and the level of the component number
against material is been passed to the dynamic internal table field
value.
IF <fs_xy> = gf_it_bom_expl-bom_mat.
ASSIGN COMPONENT l_nam OF STRUCTURE <fs_dyn_wa> TO <fs_check>.
CLEAR l_con.
MOVE gf_it_bom_expl-level TO l_con.
CONCATENATE c_val_l l_con INTO l_con.
CONDENSE l_con NO-GAPS.
IF l_con1 NE space.
CONCATENATE l_con1 l_con INTO l_con SEPARATED BY c_comma.
CLEAR l_con1.
l_cnt = l_cnt - 1.
ENDIF.
<fs_check> = l_con.
l_cnt = l_cnt + 1.
ENDIF.
ENDLOOP.
AT END OF bom_comp.
At end of every new bom component the count is moved to the field
symbol which is checked against the field of dynamic internal table
and the count is been passed to the dynamic internal table field
value.
ASSIGN COMPONENT c_count OF STRUCTURE <fs_dyn_wa> TO <fs_check>.
<fs_check> = l_cnt.
INSERT <fs_dyn_wa> INTO TABLE <fs_dyn_table>.
ENDAT.
ENDLOOP.

Dynamic Internal Table with the same name

Hey Guys
I have a question.
I know that we can create dynamic internal table taking a struct dynamically.
But I have 2 ques on the same subject.
1. Can we create an internal table based on a type that we have locally declared eg
types: begin of ty_demo.
           var1(1) type c,
           var2     type p,
          end of ty_demo.
2. If an internal table is already declared based on the above type say data: i_tab type standard table of ty_demo.
    If i need to enhance the struct of this internal table. Can i do that by dynamically redefining it based on a different structure but keepin the same name i_tab.
In a nut shell I cannot change the name of my itab but I want to enhance the structure.
I Hope I am clear.
Help will be greatly apprcieated.
Thanks
Sameer

hai.
we can create an internal table based on a type that we have locally declared, but you have to use data instead of types like.
data: begin of ty_demo.
var1(1) type c,
var2 type p,
end of ty_demo.
check the example notes for dynamic itab .

To populate data in a dynamic internal table

Hi,
I have an internal table <FS_1> which I have created dynamically. Now i need to populate the columns (7th column onwards) in the internal table with my data in GT_REQMT which is an internal table.
Data: L_IDX type I.
L_IDX = 6.
Loop at <FS_1> assigning <FS_2>.
If sy-tabix = 1.
    Loop at GT_REQMT.
     Add 1 to L_IDX.
*****I need to populate GT_REQMT-DATA to column 7 then 8 etc depending on the number of loops.
     Modify <FS_1> from <FS_2>.
    Endloop.
Else.
**do other things here**
Endif.
Endloop.
I have search through the forums and weblogs but the solutions are catered to populating the internal tables from SAP database using SQL statements.
I couldn't find anything on populating own data in dynamic table by looping it. Please help. THANKS!!
Cheers,
Chelsea

Hi!
I have used classes for dynamic internal table, SO i here give you my sample code for your help.
DATA : new_table TYPE REF TO data,
       new_line TYPE REF TO data.
FIELD-SYMBOLS : <TAB1> type standard table,
                <l_table> TYPE ANY TABLE,
                <l_line> TYPE ANY,
                <l_field> TYPE ANY.
    count = count + 1.
    clear wa_fieldcat.
    wa_fieldcat-col_pos   = count.
    wa_fieldcat-fieldname = 'CONDITION'.
    wa_fieldcat-coltext   = 'Condition Value'.
    wa_fieldcat-ref_field = 'KWERT'.
    wa_fieldcat-ref_table = 'KONV'.
    wa_fieldcat-outputlen = 13.
    append wa_fieldcat to it_fieldcat.
CALL METHOD cl_alv_table_create=>create_dynamic_table
   EXPORTING
     it_fieldcatalog = it_fieldcat
   IMPORTING
     ep_table        = new_table.
ASSIGN new_table->* TO <l_table>.
CREATE DATA new_line LIKE LINE OF <l_table>.
ASSIGN new_line->* TO <l_line>.
ASSIGN COMPONENT KWERT OF STRUCTURE <l_line> TO <l_field>.
<l_field> = t_kschlkonv-vtext.
NOw u append internal table
IF its helps you then dont forget to rewards points.
