Accessing a field in nested internal table

Hi,
Could you please help me how to get value in nested structure 'COMT_PRODUCT_IL_API'.
We need to access field 'DESTINGUID' in that nested structure.
Thanks,
Santosh

Helo,
I figured the previous reply would have solved ur issue,
but doesnt look like as you ve still kept the issue open.
So il again as well follow d same lines n leave a snippet fr yu to refer:-
DATA : LT_COMT_PRODUCT_IL_API TYPE TABLE OF COMT_PRODUCT_IL_API,
LW_COMT_PRODUCT_IL_API TYPE COMT_PRODUCT_IL_API,
** i AM NOT SURE WHCIH DEEP STRUCT it is, Im just picking one of the deep strucs in this struc**
LW_COMM_IL_ACCESS TYPE COMT_IL_ACCESS_MAINTAIN.
LOOP AT LT_COMT_PRODUCT_IL_API INTO LW_COMT_PRODUCT_IL_API.
READ TABLE LW_COMT_PRODUCT_IL_API-COMM_IL_ACCESS INTO LW_COMM_IL_ACCESS INDEX 1.
IF SY-SUBRC = 0.
+<UR CODE HERE>+
ENDIF.
ENDLOOP.
Shoudl work.
Please close the thread if ur issue lays resolved

Dynamic access to the fields of an internal table

Hi,
Currently i'm having 10 fields in 1 internal table, and i need to validate this 10 fields but i dont like have too many "if and endif" statement. Is there any option to write an dynamic code.
Example
Data: begin of table,
           field1 type c,
           field2 type c,
           field3 type c,
           field4 type c,
           field10 type c,
         end of table.
Let say i want to fill field1 with 1, field2 with 2,........................... field10 with 10.
So instead of using this code
table-field1 = '1'.
table-field2 = '2'.
table-field3 = '3'.
table-field10 = '10'.
Can i do something dynamic like this
DO 10 times.
Dynamic coding, any idea ?
ENDDO.

Hi,
Sorry may my question is not detail enough. I would like to read the field from the internal table dynamically.
Data: begin of table,
field1 type c,
field2 type c,
field3 type c,
field4 type c,
field10 type c,
end of table.
Let say i want to fill field1 with 1, field2 with 2,........................... field10 with 10.
So instead of using this code
table-field1 = '1'.
table-field2 = '2'.
table-field3 = '3'.
table-field10 = '10'.
IF table-field1 < 0,
endif.
IF table-field2 < 0,
endif.
IF table-field3 < 0,
endif.

Hi
I dont think this requirement is possible. Even if we pass the data through the nested internal table the FM may not give a dump. The main problem will be with field catalog. How can we build field catalog for the fields inside the nested internal table.
Field catalog for this FM REUSE_ALV_GRID_DISPLAY should be of type SLIS_FIELDCAT_ALV and this is a standard one.

Problem reading data from nested internal table.

Hi,
Below is my code;

         fknum LIKE vfkk-fknum,

data: it_freight_costs type v54a0_scdd_tab occurs 0.
*****Here data is getting appended to it_freight_costs. P_frieght_costs is coming from standard program.
     move p_freight_costs TO wa_FREIGHT_COSTS.
     append wa_freight_costs to it_freight_costs.
     clear wa_freight_costs.
***Now the problem is here. I am not able to read the data from the nested internal table x-item.
if i use <fs_f_costs> to move data from it_freight_costs in the outer loop, i get a syntax error; <i> "the line type of the table it_freight_costs is not compatible with field symbol type <fs_f_costs>" </i>
     FIELD-SYMBOLS: <fs_f_costs> type line of v54a0_scdd_tab.

              <b> I want to read <fs_freight_item>-vfkp-netwr.</b>
         ENDLOOP.
Can anyone guide me?

A quick look at how I would do this. Note I haven't checked if this compiles just done a quick brain-dump.
DATA: lr_f_costs TYPE REF TO v54a0_scdd_tab,
        lr_f_cost TYPE REF TO v54a0_scdd.
LOOP AT it_freight_costs REFERENCE INTO lr_f_costs.
    LOOP AT lr_f_costs->* REFERENCE INTO lr_f_cost.
    ENDLOOP.
ENDLOOP.
As you can see I personally prefer pointers to field symbols - I don't believe there is any performance differences and because of my background in other languages pointers make more sense to me.

What are nested Internal tables

Hi Guru's,
I am new to ABAP ...just trying to learn things.Can you please explain me what are nested internal tables and what is the purpose of nested internal table?where can it be used and why a header line is not written in a Nested Internal table...
Kindly explain it (scenario where nested internal tables are used) with an example it will be helpful.
Cheers,
Priyanka

Hi,
When storing data in internal tables, you often use one internal table for each database you read.
Each one contains some or all columns of the relevant database table. It is up to you whether
you create an internal table with a flat structure for each database table or if you create, for
example, internal tables with nested structures. If you have several tables, each one with a flat
structure, you have to work with redundant key fields to link the tables. If, on the other hand, you
use nested internal tables, you can store the data from the database tables hierarchically.
Saving and processing very large amounts of data in internal tables has disadvantages. If you
divide up the data into different internal tables, processing it can be very runtime-intensive, since
the tables have to be processed individually. Furthermore, it requires a lot of storage space,
since internal tables are not stored in compressed form. The system may even need to store the
dataset outside of its working memory. This means that processing it takes even longer.
An example of nested internal table:
Assume the following program is linked to the logical database [Page 1163] F1S.

Reading from select-options field into the internal table

Hi,
I have to read the low and high ranges from the select-options fields into a field in the internal table in order to update the same field in line item table. since the user may change the screen fields, i need to pass the values directly from the screen and store it in a variable in the internal table. Is there a way to pass both ranges, low and high to one variable which holds the entire range?
Thanks,
Sruthy

Hi,
In the Selection screen you can directly read the field(Select-option)value using read statement as follows:
READ TABLE <SELECT-OPTIONS field name> [using index] INTO <work area>.
After reading you can directly access all the values as follows and can store them in the variables:
var1 = <work area>-LOW
var2 = <work area>-HIGH
var3 = <work area>-SIGN
var4 = <work area>-OPTION
as per your requirement.
I think this will help you.

How to create dynamic nested internal table

Hi Experts,
Pleae tell me or give sample code, how to create dynamic nested internal table ?
I have seen threads saying creation of dynamic internal tables using some table structure only. But now the requirement is to create dynamic nested internal table.
For example the internal table contains two fields viz., one is field1 of dynamic internal table and other is normal field2 and values as shown below:
Nested internal table:
field1                     |     field2 ...
<table content1>     |     value2..
<table content1>     |     value2..
Here the [table content] should also a dynamic internal table.
Let me know if you need any other info.

Field catalog for internal table in ALV

In my program the internal table consists many fields from various tables and structure doesn't belong to a single data table.
In order to get output in ALV grid following FM has been used
REUSE_ALV_GRID_DISPLAY
for field catalog the fields are defined specifically.
l_fieldcat-fieldname = 'VBELN'.
l_fieldcat-outputlen = 10.
l_fieldcat-seltext_l = 'Billing doc'.
l_fieldcat-no_zero = 'X'.
l_fieldcat-hotspot = 'X'.
append l_fieldcat to p_fieldtab.

Just wanted to know is there any other method to display all the fields of this internal table automatically so each field is not specified specifically.

Changing the order of fields in an internal table

Hi all,
I'm using field symbol as internal table. this table has got a standard database structure.
I want to make the 3rd column of this internal table as 1st colums keeping rest of the columns as it is.
Is there any way to do this?
Thanks,
Anil.

Hi
Instead of directly taking the type as a standard structure , declare the FS internal table as type of types structure.
Data: fs_scarr like type_s_scarr.
FIELD-SYMBOLS <scarr2> TYPE fs_scarr
In the types put the third column as first one and use into corresponding in select query
or else
while displaying the internal table change the order of the columns
Loop at itab into fs_itab.
write : col3
col2
col4
endloop.

Aggregate a numeric field in an internal table

Hi All,
I have a small requirement in ABAPit goes in this fashion
I need to aggregate a numeric field in an internal table, the table is as follows
FLD1        FLD2         NUM1       FLD3
123A        B1             10            C1
123A        B1             25            C1
123B        B1             20            C2
123C        B2            10             C3
Note: FLD1, FLD2, FLD3 are of type numeric characters and NUM1 is of type number or integer
I want the result to be as follows
FLD1        FLD2        NUM1        FLD3
123A        B1            35             C1
123B        B1            20             C2
123C        B2            10             C3
i.e. values in field NUM1 should get add up when the values in all other fields are same
I am not able to use _collect_ for this as the fields contain numeric characters.

Antony

I need to add check whether 21 fields of a internal table are empty or not.

Hello,
I need to add check whether 21 fields of a internal table are empty or not.How can we write a code for the same wand what would be the correct syntax for it.
I tried entering all the fields in the IF loop with AND condition but its giving syntax error.Perhaps this is because the lenght of the IF condition would be more than the allowed one.

I think nested and deep structure internal tables will not work with gui_download.
you need to convert before giving it to gui_download
