Dynamic Internal Table in Function Module

Hi,
I am developing a function module which is similar to GUI_DOWNLOAD. So , In My function module I would like to pass the internal table dynamically.I saw the paramter DATA_TAB in the function module GUI_DOWNLOAD. But there is no type associated with that. Could anyone help Me out for achieving thsi fucntionality.
Regards
Elini.P

Hi Elini,
When the tables parameter of the function module has got no line type specified, it will acquire the same type as the parameter that is passed to it during the call. In other words, the table is of generic type. you can pass any table to that parameter.
However, in case your function module is Remote Enabled, you will not be able to define the tables parameter as generic. IOt must be given some line type.

Download database table content into internal table using Function Module?

Hi Shabeer,
We don't require a function module to download ddic table content to an internal table. We can use the SELECT statement for the same. Example would be:-
DATA: <INTERNAL TABLE> type table of <DATABASE>.
SELECT * FROM <DATABASE> into corresponding fields of <INTERNAL TABLE>.
Also, function module might be required when you need the data from a remote system, but then it is the developer's task create this function module and the function module should be remote enabled function module.
This remote enable function module should have the above SELECT query as its code.

How to get data to internal table from function module tr_inspect_objects

How to get data from funtion module to an internal table .
function module name is tr_inspect_objects(code inspectore se10)
how top collect all task request data into one internal table using this fm or we have to create another fm .
If you have already made FM please give us the code .

Hi,
You can use tables E070 or E071 to get data into your internal tables instead of a function module.
Hope this helps.

How to delete data from dynamic internal table

Hi,
I have dynamic internal table and I have some slection screen fields , using these selection screen fields
(select -options), I have to filter the data? assigning will work with READ , but I have select options not the parametre,
and also delete will not work for dynamic table..
as we cannot use assigning with delete..
So how to do this?
and one more thing is , I cannot filter the data while selection( in select, I cannot filter the data-> as it's not coming directly from table, it's coming from buffer),
so now after selection of data, I need to filter the data from dynamic table.
Is there any way to do this?

How to do parallel processing with dynamic internal table

Hi All,
I need to implement parallel processing that involves dynamically created internal tables. I tried doing so using RFC function modules (using starting new task and other such methods) but didn't get success this requires RFC enabled function modules and at the same time RFC enabled function modules do not allow generic data type (STANDARD TABLE) which is needed for passing dynamic internal tables. My exact requirement is as follows:
1. I've large chunk of data in two internal tables, one of them is formed dynamically and hence it's structure is not known at the time of coding.
2. This data has to be processed together to generate another internal table, whose structure is pre-defined. But this data processing is taking very long time as the number of records are close to a million.
3. I need to divide the dynamic internal table into (say) 1000 records each and pass to a function module and submit it to run in another task. Many such tasks will be executed in parallel.
4. The function module running in parallel can insert the processed data into a database table and the main program can access it from there.
Unfortunately, due to the limitation of not allowing generic data types in RFC, I'm unable to do this. Does anyone has any idea how to implement parallel processing using dynamic internal tables in these type of conditions.
Any help will be highly appreciated.
Thanks and regards,
Ashin

DYNAMIC INTERNAL TABLE CREATION BASED ON THE CONTENT OF ANOTHER INTERNAL TA

Hi All
I need to create an internal table at runtime.
I have a selection screen parameter which is specific to country, Which can take values below
eg:- IT_AREA for Italy(IT)
FR_AREA for France(FR)
IE_AREA for Ireland(IE).....And similary for other countries
Based on the Above parameter, I need to create Internal Table as below
DATA: itab TYPE italy_data Occurs 0.
If I declare as above, Then itab has fields from italy_data. And this internal table i will be sending it to Function Module to get data into it.

        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....

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.
Mansi

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.

Passing the Dynamic Internal Table as the Output Parameter of the FM...

Hi,
How can we pass the internal table as the output from the Function Module TABLES parameter.
    SELECT * FROM TVRO BYPASSING BUFFER INTO TABLE <ltable>.
Now I need to pass the dynamic internal table <ltable> as the output in the function module.
Thanks!
Puneet.

I can't use TVRO as the table type. The Table name is as the Input. This program will download the contents of the table and create an app server file. It can be for any database table.
so i want the output of this FM should be the data from that table. So what should be the TABLE type.
like in a program i will use:::
FIELD-SYMBOLS: <ltable> TYPE ANY TABLE,
                 <l_line> TYPE ANY,
                 <l_field> TYPE ANY.
    SELECT * FROM (p_table) BYPASSING BUFFER INTO TABLE <ltable>.
That is my requirement.

Passing dynamic internal table to FM using RFC

Dear All,
Is it possible to pass a dynamic internal table to a function module using RFC?
If it is possible than how do i achive this?

Basically not, RFC enabled FM parameters must be defined by a LIKE or TYPE clause. so you may try to use a prededined SAP type wide enough (e.g. TAB512 ) and map the data in the FM and caller program (in Unicode try to use tools like class CL_ABAP_CONTAINER_UTILITIES to map data between actual internal table record and RFC used itab "container" type)
For examples look at RFC enabled RFC_GET_TABLE_ENTRIES FM, and look for where-used program.

Raymond
