Dynamic itab creation

Hi friends,
Have run into to trouble trying to create a dynamic structure as follows
"Material Land Nov.09 Dez.09 Jan.10 Feb.10 Mar.10 TotalCount"
The dates are created dynamically with regard to the time period entered in the select options.
The first 2 fields("Material","Land" and the last field "TotalCount") will always be there.The date fields have to change according to the dates entered.
The code Iam attaching is a compilable code with which Iam trying for this purpose.
Would be helpful and I would really appreciate it if someone could change the code I attached and show it how it works....
Moderator message - Please respect the 2,500 character maximum when posting. Post only the relevant portions of code, butr search before posting - locked
The code gives a dump at the call
"CALL METHOD cl_alv_table_create=>create_dynamic_table"
Please advice what iam doing wrong.
->If the dynamic itab is created ,how to fill it with values.
For example.- I want to access specifically the field names like itab-dez.09 or itab-Feb.10 to put values in it.Is it possible?
->If I write this itab using "Write" statement - Will the field names be written
For example - the following field names.
"Material Land Nov.09 Dez.09 Jan.10 Feb.10 Mar.10 TotalCount"
Thanks

Excel Upload and moving the data to dynamic itab

Hi Folks,
I am building a fieldcatalog dynamically based on the table name and then creating a dynamic internal table based on the fieldcatalog.Now I have a excel sheet having the fields in the same structure as the fieldcatalog that I built.I want to upload the data in the excel to an internal table having the structure of the fieldcatalog I built.I am having a problem in moving the data from the excel to the itab (dynamic itab built based on the fieldcatalog)
1.Building the fieldcatalog.
data:gt_fieldcat TYPE lvc_t_fcat.
ls_fieldcat-tabname = p_tabname.
ls_fieldcat-fieldname = p_fieldname.
ls_fieldcat-inttype = 'C'.
ls_fieldcat-outputlen = wa_dfies-outputlen.
ls_fieldcat-coltext = wa_dfies-fieldtext.
APPEND: ls_fieldcat TO gt_fieldcat.
CLEAR : ls_fieldcat.
2.Building the dynamic itab
DATA:gp_table TYPE REF TO data.
FIELD-SYMBOLS: <gt_table> TYPE table,
CALL METHOD cl_alv_table_create=>create_dynamic_table
 EXPORTING
 it_fieldcatalog = gt_fieldcat
 IMPORTING
 ep_table = gp_table.
ASSIGN gp_table->* TO <gt_table>.
3.Now I have an excel with a similar structure with data.Uploading the excel data into itab.
DATA: g_t_xltab TYPE STANDARD TABLE OF ty_xltab,
 it_rawdata TYPE truxs_t_text_data,
CALL FUNCTION 'TEXT_CONVERT_XLS_TO_SAP'
 EXPORTING
* I_FIELD_SEPERATOR =
 i_line_header = 'X'
 i_tab_raw_data = it_rawdata
 i_filename = xls_filename
 TABLES
 i_tab_converted_data = g_t_xltab[]
 EXCEPTIONS
 conversion_failed = 1
 OTHERS = 2.
IF sy-subrc <> 0.
 MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
 WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
Endif.
*Move the data that got uploaded from excel into
*respective internal tables.
 LOOP AT g_t_xltab
 here I want move the data into an internal table having the structure I built using
 the fieldcatalog/dynamic itab ie <gt_table>.
 Endloop.
I tried using ASSIGN COMPONENT sy-index of <gt_table> and move-corresponding but in vain as I am not that much familiar with dynamic itab using field symbols.Kindly let me know how the excel data can be moved to dynamic itab.
Thanks,
K.Kiran.

Hi,
you can try some logic like this. Please note this is just an example

 it_rawdata TYPE truxs_t_text_data.
CALL FUNCTION 'TEXT_CONVERT_XLS_TO_SAP'
 EXPORTING
* I_FIELD_SEPERATOR =
 i_line_header = 'X'
 i_tab_raw_data = it_rawdata
 i_filename = ' '
 TABLES
 i_tab_converted_data = g_t_xltab[]
 EXCEPTIONS
 conversion_failed = 1
 OTHERS = 2.
IF sy-subrc <> 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
 WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
startpos = 0.
LOOP AT g_t_xltab INTO wa.
DO.
 ASSIGN COMPONENT sy-index OF STRUCTURE <fs_line> TO <fs>.
 IF sy-subrc = 0.
 DESCRIBE FIELD <fs> OUTPUT-LENGTH lv_len.
 IF lv_len > 0.
 <fs> = wa-field+startpos(lv_len).
 startpos = startpos + lv_len.
 ENDIF.
 ELSE.
 append <fs_line> to <fs_tab>.
 EXIT.
 ENDIF.
ENDDO.
ENDLOOP.
Sorry my answer is not for you requirement..Please Ignore.
Your solution can be easily solved by looking at the concept Assign component . Please search

How to MODIFY a dynamic ITAB...

Hi!!!
I wants to modify a dynamic itab in a Z-programme which takes inputs. But I can not use the normal itab modifying syntax for it. Therefore I needs to find out a way to modify this itab and it is really essential for my programme.
Please help me on this...
Thanking You,
Yohan.

Thanks for the prompt replies.
Dear Amit,
I have already done the things mention in the link you sent me. This is ok for when I loop the dynamic itab step by step. So it will modify the itab, line by line. But, what I wants to do is modify an itab field which have the same key in multiple lines.
For an example say in my structure I have material #. I wants to update all the rows of column 'material description' which have the same material #.
This is where I have stucked...
Please help me...
Thanking you,
Yohan.

Hi
I thought my sample was clear:
The "GT_MONTHCALC" itab we dont need anymore,as It was used only to fill in the fieldcatalog with months.
If I rember a your requisition is to create the name of the month concatening the short name and the year, something like this:
NOV09 DEC09 GEN10 FEB10 MAR10 APR10 ..........
In this case the fieldname of month of your dynamic table doesn't corrispond to value in gs_tab-month as here you have stored the short name of the month only.
I suppose if gs_tab-month is nov, the quantity has to move in the field called NOV09, if it's so it needs to get a link in order to know the real name of the moth field of dynamic table.
This link can be in GT_MONTHCALC only, because you've used it to create dynamic table.
Now I've create a routine to transfer the value from GS_TAN to <FS_WA>:
FORM MOVE_VALUE USING P_FIELD
 P_VALUE.
ASSIGN COMPONENT P_FIELD OF STRUCTURE <FS_WA> TO <FS_VAL>.
MOVE P_VALUE TO <FS_VAL>.
ENDFORM.
P_FIELD is the name of dynamic table field
P_VALUE is the value to be transfered
Now I want to
copy the contents of the field "matnummer" to "mat" in fS_itab
copy the contents of the field "soldto" to "OPCO" in fS_itab
This requirement is easy because the name of the dynamic table are constant:
loop gt_tab into gs_tab.
 CLEAR <FS_WA>.
* Move material code
 PERFORM MOVE_VALUE USING 'MAT' GS_TAB-MATNUMMER.
* Move soldto
 PERFORM MOVE_VALUE USING 'OPCO' GS_TAB-SOLDTO.
copy the contents of the field "dqty" to "NOV" in fS_itab
In this case you need to move the value to FS_ITAB-NOV09, so:
Found the name of dynamic table:
TRANSLATE FS_ITAB-MONTH TO UPPER CASE.
LOOP AT GT_MONTHCALC INTO GS_MONTHCALC.
 IF GS_MONTHCALC-MONTH(3) = FS_ITAB-MONTH.
* I found the right name
 EXIT.
ENDIF.
ENDLOOP.
* Move qty
PERFORM MOVE_VALUE USING GS_MONTHCALC-MONTH GS_TAB-DQTY.
I hope it's clear now

Hi Shinjan,
One of the ways to achieve this is by creating ranges. Try this code,
TABLES: dbtab2.
FIELD-SYMBOLS: <l_line> TYPE ANY,
 <l_field> TYPE ANY.
DATA: new_line TYPE REF TO data.
RANGES: r_f1 FOR dbtab2-f1. "Create ranges for the particular field say f1
"Creating work area for your dynamic int table
CREATE DATA new_line LIKE LINE OF <fs_itab>.
ASSIGN new_line->* TO <l_line> .
LOOP AT <fs_itab> ASSIGNING <l_line>.
ASSIGN COMPONENT 'F1' OF STRUCTURE <l_line> TO <l_field>. "Now <l_field> contains the value
"Append the range from the values in dynamic tab
r_f1-sign = 'I'.
r_f1-option = 'EQ'.
r_f1-low = <l_field>.
APPEND r_f1.
ENDLOOP.
SELECT *
FROM dbtab2
INTO t_dbtab2
WHERE f1 IN r_f1. "write the select query using the ranges
Hope this helps you.

Does Seeburger's SFTP adapter support dynamic filename creation

Hi all,
Does the SFTP adapter support dynamic filename creation.
If yes, then do we have to use UDF's and are there any specific settings that have to be done in the SFTP communication channel.
Please provide a blog which helps in the configuration process of the above case.
thanks,
younus

Dynamic Creation of File using counter in Seeburger Variable:
1. Configuration Needed in the Communication Channel:
The process of dynamic creation of files can be done we have to select the following checkbox in the receiver channel:
Dynamic Attribute in receiver Channel:
Import the following modules:
Localejbs/Seeburger/solution/sftp
Localejbs/Seeburger/AttribMapper
Localejbs/ModuleProcessorExitBean
Enter the desired file naming convention:
Use the Parameter GetCounter("ID") to the place where the counter is expected to come.
2. Configuration Needed in the SeeBurger Workbench:
If the J2EE server is listening on a port different from 50000 (which is the standard for the SAP client 000), the port number must be configured:
Login into the seeburger workbench using the URL
http://<localhost>:<port number>/seeburger/index.html
Select Property Store.
Create or edit the following property:
Parameter
Value
Namespace
http://seeburger.com/xi/SeeFunctions
Key
provider.servlet.server
Value
http://localhost:50000/ (where the port number 50000 must be set
accordingly to the J2EE server configuration).
Note: The configured value (server URL) has to end with a slash (/). Otherwise,
SeeFunctions will not work correctly.
If we need to start the counter from any specific value , it can be configured in the SeeBurger workbench, this value can be maintained in Mapping Variables :

Does UCM support dynamic page creation on contributor mode.?

Hi All,
Does UCM support dynamic page creation on contributor mode.
We want to create new pages and link it into the existing pages
is that possible?
Thanks
~Hari

You can create new secondary pages in contributor mode - you would normally do this via a dynamic list fragment though technically you could also achieve it by switching region content and creating new data files. You can then use the linz wizard to link between pages.
If you are talking about creating new primary pages and sections in your site then you would need to use something like Site Studio Manager fragment.

with advance appreciation,
Matthew

Dynamic Event Creation and Handling the events

Hi All
I am using WAS 6.4.
I have two components say Component A and Component B in which Component A is a reusable component and is used by other components say for e.g the Component B.
The following is the requirement.
Component A should create buttons for other components dynamically.
As an example, Component B specifies to Component A the buttons required say button B1 and button B2.
Component B also contains methods M1 and M2 for the buttons created by the component A.
Now I would like to associate these buttons created by component A with the methods created in Component B
The number of buttons that are to be created may vary from component to component.
If any one as any suggestion or solution, help me out.
Thanks
Regards

Hi NagaKishore,
 I'm not exactly sure why you want to do this, but it is pretty easy if I switch it up a bit. (Maybe you are trying to create a navigation page or something?)
 Instead of your component B using component A, if you define a Web Dynpro interface in component A, then implement this interface in component B (or all component Bs), achieving your goal would not be too difficult. It could define a generic method (or event) with a "button key" as an argument that would tell component B which button was pressed and allow it to behave as desired. The Web Dynpro interface defined in A could also have an interface context that would allow the the button text to be passed along with (for the sake of simplicity) a "button key" that component that should be triggered when the button is pressed. (Note this could be a varying size list as required.)
 The component B(s) need not be known until run-time. They can be created using something like:
wdThis.wdGet<Used Compontne Name>ComponentUsage().createComponent(<Component Name>,<Object Name (if in a different component)>)
 Once the component is created, the context can be accessed giving the list of buttons to create and the values. The buttons can be created in the wdModifyView during the first pass of the creation of the view displaying the buttons (after the dynamic creation of the used components which can occur in the wdDoInit of the component controller).
 If the user presses a chosen button on component A, then the generic method (most likely an event) of component Bs interface is called and passed the "button key", component B then takes over. Note this would also work if component B had a visualization component that must be displayed through an interface view that is defined on the web dynpro component interface that is implemented by B.
 Hope this helps or at least triggers discussion that will answer your question,

Dynamic ITAB in function module parameter

Hi
How to define in FM dynamic internal table returning some values in.
For example I want to call FM with any internal table structure and FM must return fill in ITAB.

I got it.
I added type standard table to parameter.

Dynamic ITAB copy problem with field type P

Hello everyone
I need to copy the structure of an internal table that is pass by reference into a method.
Actually everything is fine else than the field type P with decimal is not created properly in the new itab.
Scenario:
An internal table is pass by reference to a method. We need to trait the data without modifying the original table. The Idea is to copy the structure and the data of the referenced internal table into an internal table created dymanically in the method.
Here is what I did and working fine when there are no field of data type "CURR".
Extract the structure of the reference data.
Create a dynamic internal table.
So far so good. Everything seams to work fine. BUT
when I am trying to copy the data from the reference table to the just created internal table the field with data type "CURR" doesn't work.
Here is my example:
FIELD-SYMBOLS: <FS_TABLE> TYPE STANDARD TABLE,
 <TMP_TABLE> TYPE STANDARD TABLE,
 <LS_TMP_TABLE> TYPE ANY,
 <LS_TABLE> TYPE ANY,
 <LS_VALUE> TYPE ANY.
DATA: lt_data TYPE STANDARD TABLE OF vbak,
 ls_data LIKE LINE OF lt_sortfield,
 ref_data TYPE REF TO data,
 l_structure TYPE REF TO DATA,
 lv_ltname TYPE string.
select * from vbak UP TO 10 rows INTO CORRESPONDING FIELDS OF TABLE lt_data.
* --- Assign the reference variable to the table
* ---- Only use to simulate a parameter that is assign to a reference to a internal table
unassign <FS_TABLE>.
lv_ltname = 'lt_data[]'.
ASSIGN (lv_ltname) to <FS_TABLE>.
GET REFERENCE OF <FS_TABLE>[] INTO ref_data.
* --- Assign the reference to the field-symbol
UNASSIGN <FS_TABLE>.
ASSIGN ref_data->* TO <FS_TABLE>.
* --- Create a working area for the reference table to a field-table
CREATE DATA l_structure LIKE LINE OF <FS_TABLE>.
ASSIGN l_structure->* TO <LS_TABLE>.
* --- Retrieve the structure of the field-symbol pointing to the internal table
DATA: lr_tabledescr TYPE REF TO cl_abap_tabledescr, " Internal Table description
 _r_structdescr TYPE REF TO cl_abap_structdescr.
lr_tabledescr ?= cl_abap_tabledescr=>describe_by_data( <fs_table> ).
_r_structdescr ?= lr_tabledescr->get_table_line_type( ).
* --- Read internal table structure to create dynamic internal table
data: ls_struc like LINE OF _r_structdescr->components,
 xfc type lvc_s_fcat,
 ifc type lvc_t_fcat.
* --- Why the field (component) NETWR length is now 8 instead of 15?
LOOP AT _r_structdescr->components into ls_struc.
clear xfc.
xfc-fieldname = ls_struc-name .
xfc-datatype = ls_struc-type_kind.
xfc-inttype = ls_struc-type_kind.
xfc-intlen = ls_struc-length.
xfc-decimals = ls_struc-decimals.
append xfc to ifc.
ENDLOOP.
DATA: dy_table type ref to data,
* --- Create dynamic internal table
call method cl_alv_table_create=>create_dynamic_table
EXPORTING
 it_fieldcatalog = ifc
IMPORTING
 ep_table = dy_table.
* --- assign reference internal table to Field-symbol
assign dy_table->* to <tmp_table>.
unassign <ls_tmp_table>.
DATA: ls_tmp_struc type REF TO DATA.
CREATE DATA ls_tmp_struc like LINE OF <tmp_table>.
ASSIGN ls_tmp_struc->* TO <ls_tmp_table>.
Loop at <fs_table> INTO <LS_TABLE>.
MOVE-CORRESPONDING <ls_table> TO <ls_tmp_table>.
APPEND <ls_tmp_table> TO <tmp_table>.
ENDLOOP.
* <fs_table>-netwr length is 15
* <ls_tmp_table>-netwr length is 8
* ??????????? Why the length is different?
* ??????????? It should a structure copy and have the
* ??????????? same length
I use VBAK as example, and the field NETWR is using data type "NETWR_AK" where it us a data type "CURR" with length 15 and decimal 2.
When reading the structure, the method get_table_line_type of the class cl_abap_tabledescr return a length of 8 instead of 15.
Any idea how to get the exact structure of a variable that is refering to a data type?

Daniel

Hello Everyone
Thank you for your replies.
I think I didn't explain myself clearly.
My goal is to be able to create an exact structure copy of a "Type ref to data" into a new internal table that is not defined yet.
Example:
A method contain a parameter that is a ref to DATA type.
That parameter is refering to an internal table from the calling program.
Now I want to create an internal table into the method where this one will be an exact structure copy of the parameter.
So, lets put some name here.
parameter: ip_data type ref to data.
FIELD-SYMBOLS: <FS_REF_DATA> TYPE STANDARD TABLE,
 <FS_CP_DATA> TYPE STANDARD TABLE.
ASSIGN ip_data->* TO <FS_REF_DATA>.
" some code to assign the same structure to <FS_CP_DATA> from <FS_REF_DATA>
" than copy the data from <FS_REF_DATA> to <FS_CP_DATA>.
<FS_CP_DATA> [ ] = <FS_REF_DATA> [ ]. " This is working if no type P with decimal exist into the structure
" Than I can play with the data of <FS_CP_DATA> without modifying the data of <FS_REF_DATA>.
My problem would be solved if I can create dynamically an internal table that has an exact structure copy of the passed parameter.

Daniel

Dynamic Type creation: structure

Hey,
I made a dynamic table and now I want to loop this table.
But I can't seem to make a structure to use in the loop.
I get the error 'data object has no structure'.
This is what I already have.
data: linetype type ref to cl_abap_structdescr,
 tabletype type ref to cl_abap_tabledescr,
 lt_comp type cl_abap_structdescr=>component_table,
 lr_table type ref to data,
 lr_line type ref to data.
field-symbols: <lt_data> type table,
 <ls_data> type any.
...first I fill lt_comp ...
linetype = cl_abap_structdescr=>create( lt_comp ).
tabletype = cl_abap_tabledescr=>create( p_line_type = linetype p_table_kind = 'S' ).
create data lr_table type handle tabletype.
assign lr_table->* to <lt_data> casting type handle tabletype.
create data lr_line like line of <lt_data>.
assign lr_line->* to <ls_data> casting type handle linetype.
... filling the table <lt_data> ....
loop at lt_data assigning <ls_data>.
... when I try to access a field of <ls_data>, I get the error '<ls_data> is no structure'.
endloop.

Hello Steven
If you are going for dynamic programming then you have to use "the full monty" meaning field-symbols for:
- itab
- structure AND
- fields
FIELD-SYMBOLS:
<ld_fld> TYPE any.
LOOP AT <lt_data> ASSIGNING <ls_data>.
 UNASSIGN <ld_fld>.
 ASSIGN COMPONENT '<name of field OR sy-index>' OF STRUCTURE <ls_data>
 TO <ld_fld>.
 IF ( <ld_fld> IS ASSIGNED ).
" do something...
 ENDIF.
ENDLOOP.

 Uwe
