Accessing Dynamic Internal table fields

Hello All,
I have one internal table ep_tabx having 138 columns whose data is getting displayed
by using function module reuse_alv_grid_display.
Now my query is, i have created one custom button on the appl toolbar to download ep_tabx data.
IF the user changes the the layout of the output at runtime and then presses that custom button
then i have created one dynamic internal table using call method cl_alv_table_create=>create_dynamic_table suppose <dyn_table> whose struc will be that of
dynamic fieldcatalog returned by using FM REUSE_ALV_GRID_LAYOUT_INFO_GET.
And then I have put a loop on the int table ep_tabx and move corresponding to the int table
<dyn_table>. But when i download the <dyn_table> data through GUI_DOWNLOAD the
date fields data is not getting downloaded correctly. I have 4 date fields in my ep_tabx.
In the alv grid output the date is getting displayed like 08/30/2004(ie mon/date/yr) but in download
file it comes like 20040830(ie yr/mon/date and that too without /).How to access the dynamic
internal tables fields separately so asto convert them in the pgm before the download.
Kindly Help.
Thanks in advance.

Hi,
Search in SDN you would get loads of info on accessing dynamic itab's .
in order to convert your date format use WRITE stmt to convert the value in your itab before passing it to download FM.

How to populate dynamic internal table fields with data??

Hi Folks,
How to assign a particular internal table field to a dynamically assigned internal table?
I have an excel sheet, and i upload the excel sheet data into an internal IT_EXLOAD table using FM ALSM_EXCEL_TO_INTERNAL_TABLE
Now i created a dynamic internal table which has the same column as in my DB table.
I have to fill the dynamically created Internal table with the IT_EXLOAD data dynamically.
Suppose in future if i add some field in DB table and for that field if i add some column in excel sheet there is no need to change in the program.
Looking for reply...
Best Regards,
Sayak

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.

How to populate data in dynamic internal table

Hi Expert,
fyi. My dynamic internal table field is created base on data selected. Eg. select table qpcd has 5 records. These 5 recods will become fieldname to my dynamic internal table. My dynamic internal table will be
...itab
      01
      02
      03
      04
      05
The 5 records from qpcd is populated in another table call viqmel. I need to find the occurance of each code in viqmel and populate the number of occurance in itab in each of column. The final dynamic itab will be like this
table itab
01       02     03    04     05   -
> field name
2         0        1     0       1    -

hello dear i m giving u a code in this a dynamic table is made on the basis of table in database , and u can download this data correct it , see it, or even change it....and upload in tht table help full if u dont know the table name...in advance.
also the code to populate data in dynamic table is in this code like:
SELECT * FROM (MTABLE_N)

Column names of a dynamic internal table

Hi Friends,
I have a dynamic internal table flowing in my ABAP program and I want to list down the column names of the this dynamic internal table.
The declaration of this dynamic internal table :
   FIELD-SYMBOLS:
    <l_t_data>         TYPE STANDARD TABLE.
Can you please tell me how to get the column names?
Thanks,
Gaurav

Hi,
     You can use ABAP Runtime Type Identification to get the column names of the internal table.
e.g >
>lo_itab holds reference to description object of internal table whose column names i have to extract.
>Using method describe_by_data of class cl_abap_typedescr export the field symbol assigned to the table and import the object reference into lo_itab.
>Then using method get_table_line_type of lo_itab import line type description object reference into lo_line.
>Check if lo_line is referring to a structure, if yes , downcast it to a object reference lo_struct of type cl_abap_structdescr.
>The column description of all columns in the structure is stored in 'components' table of cl_abap_structdescr.
     So loop at the table to get all the column names stored in column 'name' of table 'components'.
Thank You.

Dynamic internal table problem in FM - HR_INFOTYPE_OPERATIONS

Dear All,
I have a problem when I use a Dynamic internal table in FM - HR_INFOTYPE_OPERTATION..
Please suggest me on the way to overcome this problem..
We wanted to have a dynamic Program for Info type operations which can be used for any info types as we are changing only BEGDA and the related actions
So in my program I have the parameters to accept
P_BEGDA - 01.10.2007
P_INFTY - P0008
P_ACTIO - COPY
I am able to create a dynamic table based on the parameters P_INFTY and able to read it also using the FM - HR_READ_INFOTYPE
BUT when I pass the dynamic internal table to a FM - HR_INFOTYPE_OPERTATION I am getting a DUMP
The DUMP is at the below statement from FM - HR_INFOTYPE_OPERTATION
ASSIGN record TO <record> CASTING TYPE (tabname). "XDP UniCode
It gives the below possiblities
"ASSIGN_BASE_TOO_SHORT" C
"SAPLHRMM" or "LHRMMU03"
"HR_INFOTYPE_OPERATION"
But If I use the below internal table
Data : g_t_0008 like P0008 occurs 0 with header line.
And If I use the internal table g_t_0008 instead of dynamic tables then it works. So I strongly feel it's due to not having a header in the dynamic table below see below the sample code on how I am generating a dynamic internal table
field-symbols: <dyn_table> type standard table.
data: dy_table type ref to data,
      dy_line type ref to data,
      xfc type lvc_s_fcat,

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 .
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,

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.

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.

ENDIF.

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>.

Create object/structure like dynamic internal table

Hi,
We have created dynamic internal table with some fields.
for the above how to create structure or internal table like dynamic internal table structure .
Scenario: internal table itab1 ( with header line) have 5 fields.
Based on some of the conditions in layout of the report.
we have to create dynamic internal table.
field-symbols: <FS> type standard table.
we are able to create dynamic internal table with 3 fields
with assignment <fs> = itab1[]
the columns are not appearing but data appearing in next column.
how to solve this one
Thanks
Ramesh

Dynamic internal tables using field symbols

Hello,
Is it possible to create a dynamic table where the no of fields in the internal table can be created dynamically(using field symbols).
Say sometimes internal tables with 10 fields and depending upon the requirement the fields can be dynamically increased or decreased in runtime.
Thanks.

Hi,

data: lt_data type ref to data.
data: lt_fieldcatalog type lvc_t_fcat.
*** Structure

*** Data References
data: new_line type ref to data,
      fs_data type ref to data.
*** Field Symbols
field-symbols: <fs_data> type ref to data,
               <fs_1> type any table,
               <fs_2>,
               <fs_3>.
*Populating the internal table with fieldnames required for our dynamic
*internal table
ls_fieldcatalog-fieldname = 'MANDT'.

Error while creating a dynamic internal table refers to custom field

Hi all,
I am getting the exception TYPE_NOT_FOUND when I try to create a dynamic internal table using:-
DATA: gr_desc TYPE REF TO cl_abap_typedescr.
gr_desc = cl_abap_typedescr=>describe_by_name( p_field ).
The field p_field is a Z-field inside a DB table, (e.g. a user added field in MARA). The statement fails at that point and gives a runtime exception. Any suggestions to how I may solve this problem? Or any alternatives for the same? I guess we face this issue for all custom fields..has SAP released a note for this??
Thanks..

that's just the wrong method, you should use DESCRIBE_BY_DATA
gr_desc = cl_abap_typedescr=>describe_by_data( p_field ).
Note: DESCRIBE_BY_NAME is to be used for referencing a DDIC type by its name. Example:
gr_desc = cl_abap_typedescr=>describe_by_name( 'MARA-ZZFIELD' ).

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,

********** 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.

How to populate field catalogue fields in ALV using dynamic internal table

Hi All,
Please let me know how to populate field catalogue fields in ALV using dynamic internal table.
I have created <dyn_table> using code below.
CALL METHOD cl_alv_table_create=>create_dynamic_table
                 EXPORTING
                   it_fieldcatalog = g_t_ifc
                    it_fieldcatalog = g_t_fieldcat
                 IMPORTING
                    ep_table        = dy_table.
ASSIGN dy_table->* TO <dyn_table>.
Create dynamic work area and assign to FS
CREATE DATA dy_line LIKE LINE OF <dyn_table>.
ASSIGN dy_line->* TO <dyn_wa>.
Now this <dyn_table> has fields like idoc no.,creation date ,
segment field 1, segment field 2 etc..Now idoc no.,creation date are static fields from table EDIDC. And segment field 1, segment field 2 etc are dynamic fields from table EDSAPPL.
In my ALV report I am getting the final layout properly but I am unable to move values to corresponding fields in the final layout shown.Please let me know how to populate these fields from different tables.
I tried this way but its not working.
SORT g_t_edid4 BY docnum.
LOOP AT g_t_edidc INTO g_r_edidc.
    READ TABLE g_t_edid4 into g_r_edid4
                     WITH KEY docnum = g_r_edidc-docnum
                                    BINARY SEARCH.
    IF sy-subrc = 0.
      <dyn_wa> = g_r_edid4-sdata.
     MOVE-CORRESPONDING g_r_edid4 to <dyn_wa>.
   CLEAR g_r_edid4.
    ENDIF.
MOVE-CORRESPONDING g_r_edidc to <dyn_wa>.
APPEND <dyn_wa> TO <dyn_table>.

You have to assign each field to field symbol and then assign the value to that field symbol and asssign that field symbol to workarea field symbol.
LOOP AT g_t_edidc INTO g_r_edidc.
READ TABLE g_t_edid4 into g_r_edid4
WITH KEY docnum = g_r_edidc-docnum
BINARY SEARCH.
IF sy-subrc = 0.
ASSIGN COMPONENT 'SDATA' OF STRUCTURE <DYN_WA> TO <DYN_FLD>.
<DYN_FLD> = g_r_edid4-sdata.
" <dyn_wa> = g_r_edid4-sdata.
" Assign each fields like this.
" MOVE-CORRESPONDING g_r_edid4 to <dyn_wa>.
CLEAR g_r_edid4.
ENDIF.
" MOVE-CORRESPONDING g_r_edidc to <dyn_wa>.
APPEND <dyn_wa> TO <dyn_table>.

Are field symbols and Dynamic internal tables consistant?

Hi,
Are field symbols and Dynamic internal tables
always consistent?
In my program I m creating a dynamic itab and assignig values to it using <FS>, sometimes the program fails to execute assign <Fs> statement...
this happens once in 3 to 4 runs
any solution...
I have proper clear and refresh statements in program.
Thanks,
Hardik

Anurag,
Thanks for a quick reply. Here I am sending a small piece of my code.
MOVE-CORRESPONDING OUTTAB TO DYNTAB.
      CLEAR IT_UDATE.
      CLEAR : T_KBETR .
      READ TABLE IT_UDATE WITH KEY UDATE = OUTTAB-UDATE.
      CONCATENATE 'DYNTAB-KBETR' IT_UDATE-CO_POS INTO T_KBETR.
      ASSIGN (T_KBETR) TO <FS> .
      SUBRC5 = SY-SUBRC .
      IF SUBRC5 = 0 .
          <FS> = OUTTAB-KBETR .
      ENDIF .
read statement will always return CO_POS .
while debuging this code a few times
<b>ASSIGN (T_KBETR) TO <FS> .</b>
returns sy-subrc = 4
and that was leading the program to short dump earlier.
now, as I have a check DYNTAB-KBETR holds no value on display.
this happens very few times. (most of the times report is displaying desired output)
Thanks,
Hardik

Dynamic Internal Table with Dynamic Fields

Hi all,
My scenario is fairly simple----
--> End user clicks a button on screen and he gets the list of HR tables.
--> Then selects a table and list of all the fields for that table gets displayed.
--> He/she selects the fields they want data to be retrieved for.
So, the requirement is, the dynamic internal table should get created with the fields selected.
The select statement should only retrieve fields which were selected by the end user
and from the table selected by the end user.
I believe the fields selected by end user can be passed by a variable of type string.
something like this---
select (fields)
from (p_table)        " Table selected by end user
into dynamic internal table.   " should contain columns selected by end user"
Appreciate your inputs and guidance.
Warm regards,
Hari Kiran
