Add column in the dynamic internal table

Hi Experts,
I have a dynamic internal table. I need add new column in the internal table and I don´t Know.
My code:
DATA: it_generic TYPE REF TO Data,
wa_generic TYPE REF TO data.
FIELD-SYMBOLS: <table> TYPE ANY TABLE,
<wa>    TYPE ANY,
<field> TYPE ANY.
CREATE DATA it_generic TYPE STANDARD TABLE OF (wa_datoscarga-ZTBLCAR).
CREATE DATA wa_generic TYPE (wa_datoscarga-ZTBLCAR).
ASSIGN it_generic->* TO <table>.
CHECK <table> IS ASSIGNED.
ASSIGN wa_generic->* TO <wa>.
CHECK <wa> IS ASSIGNED.
SELECT *
INTO CORRESPONDING FIELDS OF TABLE <table>
FROM (wa_datoscarga-ZTBLCAR)
WHERE bukrs   EQ p_bukrs      AND
z_petic EQ z_peticion   AND
ZIDFASE eq 'E'.
After this I need add one column selection at the first position of the columns.
Thanks

How to Organize the columns in the dynamic internal table?

Hello Folks!
How to Organize the columns in the dynamic internal table? i tried passing the parameter COL_POS to the fieldcatalog, Which is not working.

Organize in What order ? What is your way to output ?
If you use ALV, you need to create fresh FIELD CATALOG for your dynamic table and then assign the column position.

It cannot reference the dynamic internal table in memory as an object.

Hi,
I am getting the syntax error in the second select. I guest it cannot reference the dynamic internal table in memory as an object.
The internal table contains different fields from multiple tables and it gets created OK. Then the first select within the loop executes OK allowing me to read the multiple tables in ITABLES.
* Create dynamic internal table and assign to FS
call method cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = ifc
    IMPORTING
      ep_table        = dy_table.
***OK, the dynamic tables is created here
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>.
loop at ITABLES.
***OK, no syntax errors in this select here
select * appending corresponding fields of table <dyn_table>
             from (ITABLES-TABNAME).
endloop.
data: ikonp like konp occurs 0 with header line.
***NOT OK, there is syntax errors
select * into table ikonp
from KONP for all entries in <dyn_table>
where knumh = <dyn_table>-knumh.
Some of the tables in ITABLES are pooled tables which does not allow me to use INNER JOINS. Therefore I need a second select in order to read the pricing table KONP.
Thanks in advance for any hint.

Hi Abel,
You must be getting the syntax error that <dyn_table> does not contain the field knumh.
try putiing the entire where clause in a char type variable say wa_char and then use in ur query as
where (wa_char) .. it may work..
concatenate 'knumh' '=' '<dyn_table>-knumh' INTO wa_char SEPARATED BY SPACES.
SELECT ... from konp...
where (wa_char).
Revert if it doesnt work.

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.

How to ADD rows to a dynamic internal table??

My question is simple.
I have a dynamic internal table and I need to ADD rows to if.
I read this thread How to modify a dynamic internal table from dynamic work area but they are modifying existing data.
My internal table is EMPTY and I need to ADD new rows, so I can't use LOOP ASSIGNING.
How can I do that?
Any help is welcome!
Thanks!
Bettina

Hi,
try something similar.
FIELD-SYMBOLS: <fs> type any.
FIELD-SYMBOLS: <f1> type any.
ASSIGN INITIAL LINE TO lo_data ASSIGNING <fs>. " or <f_tab> - not sure w/o editor :-)
assigning component 1 of structure <fs> to <f1>.
<f1> = 'aaa'.
I write it from memory so there can be some syntax errors but focus to command APPEND INITIAL LINE ...

Add columns in the existing Customer table in a Subject Area

Hi All,
Well I need to add two columns from Sales table(new table i created which has customer Id) and join it to the Customer Table which has the Customer Id and several columns. The Customer table was already in the RPD which has all the customer information. Now that i have this new requirement to add few columns from the Sales table to the Customer table in one Subject Area.
What i have done so far is that I imported the sales table into the rpd, made a join in PHYSICAL LAYER on the customer ID of the Sales table to the Customer id of the Customer table and simply dragged the sales table to the Customer LTS in the BMM layer(NO MORE JOINS IN BMM)and dragged and dropped the same into the Presentation layer. The customer table is linked to one fact table in that subject area. So i thought that dragging the sales table columns in the customer table LTS will work because customer is linked to one fact in that subject area.
Now, In the Answers when I dragged columns from customer & sales table I see only one record that is the first customer_id record from my Sales table but i know there are many common customer_ids between those two tables but its only picking the first customer id from the sales table.
Any help will be appreciated..
Normally if we need to add some columns to the existing tables in one subject area what is the best approach??

                          CHANGING <dyn_table>.
you have made use of field symbol <dyn_table> which you have not assigned.... due to which you are getting a dump....
so before the call you have to assign this field symbol and then use it in the call...
just assing to some dummy type and then you pass it using changing...
later on in the called program you can unassign the field-symbol as soon as you enter in the subroutine.
data itab type standard table of scarr.
assign itab to <dyn_table>.
perform get_data(ZSD_CARRIER_SELECTION)
                           TABLES KAPPL

                          CHANGING <dyn_table>.
even if this does not solve your problem try debugging and check at which line it is going for a dump... so that it gives a clear idea where exactly is the fault

Hi,
If you really want to have a dynamic table, then you will have to find a way to generate a whole new table, and then copy the data from the old table to the new one. There is no way to modify a type during runtime in ABAP.

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,
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- column to row conversion

Hello all,
Inside a program i generate a dynamic internal table and
This table has one single column. But I need to convert the rows as columns.
Eg:
dynamic internal table ITAB has content
Forbes
Times
Reuters
Warner
stern
I would like to have a ITAB2 like this
Forbes Times Reuters Warner Stern
Please note this is a Dynamic internal table!!!!
I need some approach for my problem. Thanks a lot in advance.

Hi karthik,
1.
For this purpose,
in my program,

and from those, it consructs dynamic table.
2. Here is the program.
the dynamic table name will be
<DYNTABLE>.
3. U can use this program (FORM in this program)
to generate any kind of internal table
by specifying list of fields.

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.
My Requirement is to Create the Internal table itab during runtime for tables italy_data OR france_data OR ireland_data based on selection screen parameter. Tables on Country may have different number of fields in it.
Can anyone help me on this??

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)
