Deep structure - assign component

hi,
I have a structure like:
data: begin of wa_xxx,
 rec like bkpf,
 iba(10) TYPE c,
 bba(10) TYPE c,
 END OF wa_xxx.
Now I would like to assign the strucutre like:
field-symbols: <fs_1> like wa_xxx
loop....
assign component sy-tabix of structure <fs_1> to <fs_2>.
endloop.
The first compoment is rec, but I need <fs_1>-rec-...(fields of the structure)
How can I do this? Any Idea?
thanks
markus

Hi Markus,
I'm not sure exactly what you mean but here's some code:
types: begin of ty_xxx,
 rec like bkpf,
 iba(10) TYPE c,
 bba(10) TYPE c,
 END OF ty_xxx.
data t type table of ty_xxx.
data d type ty_xxx.
field-symbols: <el> type any, <str> type ty_xxx.
you can assign the whole structure to a field-symbol...
loop at t assigning <str>.
you can refer directly to eleemnets within the filed-symbol structure...
if <str>-bba is initial. endif.
do.
you can loop through the individual components of the field symbol structure
assign component sy-tabix of structure <str> to <el>.
if sy-subrc <> 0.
exit.
endif.
you can operate on the current element within the structure
if <el> is initial. endif.
enddo.
endloop.

ASSIGN COMPONENT x OF STRUCTURE not assigning !

Hello,
the problem is that the component PAKET is not getting assigned to my field symbol (<l_str_applparam> type any) and i don't understand why. The PAKET field is type INT4 and the value is 1111. The importing structure i_str_applparam is also type any.
See coding below:

Hello Uwe,
thank you for the first answer. I have another tiny question: i am not allowed to change the values of the import structure and i want to save them in my class, is there a simpler way to save the data besides the loop below ??

Assign Component with dynamic structure.

Hi,
I like to get a field from a structure which i read from a customizing table. I think with a snippet it is easy to understand:
FIELD-SYMBOLS: <fs_value> TYPE Any.
DATA: lv_field type text30,
 lv_structure type but000,
 lv_Structure_name type text30.
select single *
into lv_structure
from but000.
lv_field = 'PARTNER'.
lv_Structure_name = 'LV_STRUCTURE'.
ASSIGN COMPONENT lv_field OF STRUCTURE lv_Structure_name TO <fs_value>.
But this doesn't wok, because it seems, that this statement try to get the fieldname from the variable 'lv_Structure_name'.
If i replace lv_Structure_name with lv_Structure than it works, but this is not what I like.
Any ideas
Stefan

Hi,
with a little addition of a second fs:
FIELD-SYMBOLS: <fs_value> TYPE ANY.
FIELD-SYMBOLS: <fs_struc> TYPE ANY.
DATA: lv_field TYPE text30,
lv_structure TYPE but000,
lv_structure_name TYPE text30.
SELECT SINGLE *
INTO lv_structure
FROM but000.
lv_field = 'PARTNER'.
lv_structure_name = 'LV_STRUCTURE'.
ASSIGN (lv_structure_name) TO <fs_struc>.
ASSIGN COMPONENT lv_field OF STRUCTURE <fs_struc> TO <fs_value>.
it will work.

Hi All,
I am creating a dynamic table using method cl_alv_table_create=>create_dynamic_table.
The normal structure gets created. but now I want to creat a Deep structure for having information of colors also for each column. So I want to add a COLTAB type LVC_T_SCOL for colors information .

How can i point to a specific field in DEEP structure and populate it?

Hello,
I have declared a internal table as below,
DATA: BEGIN OF wa_data,
 vkorg TYPE vkorg
 vtweg TYPE vtweg
 spartTYPE spart
 field_name TYPE CHAR30
 value TYPE CHAR50
 END OF wa_data
DATA: ls_data TYPE wa_data,
 lt_data TYPE STANDARD TABLE OF wa_data.
The lt_data is populated as below,

1000-----------10-------------01------------ZTERM---------------15 days "Payment terms
1000-----------10-------------01------------MAHNA---------------09 "Dunning
Fine.
Now, i have a DEEP DEEP DEEP structure as belowm
DATA: ls_deep TYPE cmds_ei_extern. "Pls. see this deep structure 'cmds_ei_extern' in SAP DDIC / SE11
This deep structure is part of Customer master creation. Now, i would like to POPULATE this deep structure from my lt_data itab DYNAMICALLy, i mean, with out mentioning the field names (like, ZTERM, KALKS, MAHNA etc etc), bcz its these i am pulling this lt_data from a custom table, so going further business may also ADD a new record / field like BUSAB (Accouting clerk) with a value of AL (Allen Christi), hence i want to hv dynamic and its less tediuos also bcz,
We can LOOP lt_data INTO ls_data (for example, the ls_data-field_name = KALKS)
Now, point the KALKS in the deep deep deep structure and populate it with a value of ls_data-value (= 15 days)
ENDLLOOP.
Pls. let me know How can i do this, i guess, we need to use field symbols, pls. let me know the code to achieve my requirement
Thank you

Deep Structures

Hi experts,
Pls tell me how to create deep structures and use them in the program with an example?Urgent.
<REMOVED BY MODERATOR>
Edited by: Alvaro Tejada Galindo on Apr 14, 2008 5:47 PM

these are the steps to create deep structures
Procedure
In the initial screen of the ABAP Dictionary, enter the structure name in field Data type and choose Create.
A dialog box appears in which you must select the type category.
Select Structure and choose .
The maintenance screen for structures appears.
Enter an explanatory short text in the field Short text.
You can for example find the structure at a later time using this short text.
Carry out the following steps for all the components you want to insert in the structure.
You can also include structures, tables or views instead of individual components.
the link is
http://help.sap.com/saphelp_nw04/helpdata/en/90/8d7301b1af11d194f600a0c929b3c3/frameset.htm
The procedure here is described in Inserting an Include(internal table in case of deep structure).
Inserting an Include
Prerequisites
Only flat structures may be included in a table. No field refers to another structure in a flat structure. All the fields of a flat structure therefore refer either to a data element or were directly assigned a data type, field length and decimal places.
A field name may not have more than 16 places in a table. A structure therefore can only be included in a table if none of the field names of the structure are longer than 16 places.
Procedure
Place the cursor under the line in which you want to insert the include and choose Edit ® Include ® Insert.
A dialog box appears.
Enter the structure name. You can optionally enter a group name (see Named Includes) or a three-place suffix.
With the group name, you can access the fields in the include together in ABAP programs.
The suffix can be used to avoid name collisions between fields of the include and fields already in the table. The suffix is added to all the fields of the include, whereby the field name is first truncated if necessary.
Choose .
A line with .INCLUDE in the Fields field and the name of the include in the Field type field is inserted in the field maintenance screen for the table.
Select column Key if all the fields in the include should be key fields of the table.
The table key must be at the start of the field list. If you select column Key, you must insert the include after the last key field or between the existing key fields of the table.
If you do not select column Key, none of the included fields is a key field of the table.
Choose .
Result
The fields of the include are added to the table in the database. If you inserted the fields of the include as key fields, the primary index of the table is built again.
You can find information about the activation flow in the activation log, which you can display with Utilities ® Activation log. The activation log is displayed immediately if errors occur when the table is activated.
Other Options
You can display the fields contained in an include by placing the cursor on the line of the include and choosing . The fields of the include are now shown below this line. You can cancel this action with .
Enter a name in column Components.
If you want to insert the structure as an include in a transparent table at a later time, the component names may not be longer than 16 characters.
Enter the name of the type whose attributes should be used in the component in field Component name. You can enter any type (data element, structure or table type) here.
If you want to add components by entering the data type and length directly, choose Built-in type. You can now enter values for fields DTyp, Length, Dec.places, and Short description. With Component type you can switch back to the screen for entering references to existing types.
You can also enter a Reference Type in the Component Type field. If you enter a class, interface, or generic reference (ANY, OBJECT, or DATA) in the Component Type field, the R type field is set automatically. If you enter a reference type already defined in the Dictionary as a reference type, a blue arrow appears in the D type column.
If the type defined in the ABAP Dictionary or the built-in type is a reference type, set the indicator in the R Type column.
You can combine components with direct type definition and components that are defined by referencing an existing type as you like.
The reference field and reference table must be specified for components of type CURR (currency) and QUAN (quantity).
You can make these entries on the Currency/quantity fields tab page.
Now maintain the foreign keys of the structure.
Proceed as when maintaining the foreign keys of a table (see Creating Foreign Keys).
Choose Search Help, if you want to assign a search help to a structure field that points to a data element. Enter the name of a search help in the dialog box that appears. See Attaching a Search Help to a Table or Structure Field.
Save your entries once you have defined all the components of the structure.
You are asked to assign the structure a development class. You can change the development class later with Goto ® Change object directory entry.
Choose an enhancement category. For more information, see Structure Enhancements.
Choose
You can expand all the includes contained in a table with . Cancel this action with .
You can copy the fields contained in the include directly to the table with Edit ® Include ® Copy components. The fields of the include become table fields. They are no longer adjusted to changes in the include.

 ASSIGN dref_dyntab->* TO <t_dyntable>.
*--Create dynamic work area and assign to FS
CREATE DATA dref_dynwa LIKE LINE OF <t_dyntable>.
 ASSIGN dref_dynwa->* TO <fs_dyntable>.
And then i populated this <t_dyntable> which is being passed as data-table to method
CL_GUI_ALV_GRID => SET_TABLE_FOR_FIRST_DISPLAY
for ALV grid Display along with above used filedcatalog ts_fieldcatalog.
Things are fine till here, but now i have the requirement to edit selected rows of the ALV display..
As you might be aware, we need a field
 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....
Note : The overall requirement is create a deep structure for dynamically generated internal table.
Your help is highly appreciated and unforgettable..!!!!!!!

Source and destination are deep structures.. can't seem to map the detail table

So, both my source data structure and my destination structure are very similarly built:
They both have a HEADER and BODY component. The HEADER has the standard AIF fields (MSGGUID, NS, IFNAME, IFVER).
I have defined the BODY as a deep structure composed of a Header Structure + a Detail Table. Each row in the BODY has a structure with a few header fields, then a table of detail data attached to it.
In my Structure Mappings, I've created 2 rows:
The first to map BODY-HEADER to my header structure.
The second to map BODY-DETAILS to my details table. Here, I've chosen "Indirect Mapping".
Selecting that row and navigating to "Define Field Mappings", I choose my destination table (DTL) and enter the Sub-table from my source structure.
At this point, I only have 1 action - to save the data in Ztables. I'm seeing that the header data is passed in fine. But there aren't any detail lines coming through.
Any ideas?
thanks alot.
RP.

Christoph,
In your reply, I only have the ability to perform the First Structure Mapping (please see the below screenshots):
Source Structure; BODY
Destination Structure: BODY
Field Mapping:
1. Field in Dest.Struc=HDR, Sub-Table = SCH_HEADER
2. Field in Dest.Struc=DTL, Sub Table = SCH_DETAILS
I presume I'm following your suggestion, but when I try to create the other two structure mappings, I only have HEADER or BODY as available options to choose from: I've attached screenshots of the F4 dropdown of the Source Structure and also the Destination Structure fields.
I believe this is because my Interface Definition is defined as a HEADER and BODY:
Source Data Structure
Destination Data Structure

Please explain, the job of the "ASSIGN COMPONENT ".

Please read this popular example appended below. I am newbie to ABAP.
At the end of the execution the code is printing 33. Don't get it.
Please explain, the job of the "ASSIGN COMPONENT ". How or why it is printing value 33. What is the meaning of the statement, "ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>." ?
DATA: BEGIN OF LINE,
COL1 TYPE I VALUE '11',
COL2 TYPE I VALUE '22',
COL3 TYPE I VALUE '33',
END OF LINE.
DATA COMP(5) VALUE 'COL3'.
FIELD-SYMBOLS: <F1>, <F2>, <F3>.
ASSIGN LINE TO <F1>.
ASSIGN COMP TO <F2>.
DO 3 TIMES.
ASSIGN COMPONENT SY-INDEX OF STRUCTURE <F1> TO <F3>.
WRITE <F3>.
ENDDO.
ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>.
WRITE / <F3>.
11 22 33
33

DATA: BEGIN OF LINE,
COL1 TYPE I VALUE '11',
COL2 TYPE I VALUE '22',
COL3 TYPE I VALUE '33',
END OF LINE.
DATA COMP(5) VALUE 'COL3'.
FIELD-SYMBOLS: <F1>, <F2>, <F3>.
ASSIGN LINE TO <F1>.
ASSIGN COMP TO <F2>. "here you are assigning the column name which is COL3 to <f2>.
DO 3 TIMES.
ASSIGN COMPONENT SY-INDEX OF STRUCTURE <F1> TO <F3>.
WRITE <F3>.
ENDDO.
ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>.
ASSIGN 'COL3' of structure <f1> to <f3>. "it is equal to above statement.
WRITE / <F3>.
11 22 33
33
ASSIGN COMPONENT <F2> OF STRUCTURE <F1> TO <F3>. means
assigining COL3 value of the structure <f1> to <f3>, so value is 33 , it will be assigned to <f3> .it prints 33.

Read a Deep Structure

Hi Abapers, how can i read a Deep Structure? i mean, read a field inside a table that i'ts inside another table.
[TABLE1 [TABLE2-FIELD] ] -> I need read the "Field" Value

Hi Carlos
Here is an approach I believe that can help:
LOOP AT <main_table> INTO <main_wa> .
LOOP AT <wa>-<inner_table> INTO <inner_wa> .
<var_1> = <inner_wa>-<field_to_be_read> .
ENDLOOP .
ENDLOOP .

Create deep structure to disable some cells in Dynamic ALV GRID

Hi,
I want to disable some cells in a Dynamic ALV Grid before calling "SET_tABLE_Display" Method.
I check the BCALV_EDIT_02, where some cells are grayed out by assign the CL_GUI_ALV_GRID-MC_STYLE_DISABLED to the field name.
But I want the same using Field symbol.
I'm creating Dynamic table and dynamic structure based on the Dynamic field catalog.
Example: <FT_TAB> TYPE STANDARD TABLE,
 <FS_TAB> TYPE ANY,
DATA: INT_TAB is my dynamic table values.
For the INT_TAB internal table, I created dynamic Structure and dynamic field symbol table.
LOOP AT INT_TAB.
ASSIGN COMPONENT 'MATNR' OF STRUCTURE <FS_TAB> TO <F_VALUE>
<F_VALUE> = INT_TAB-MATNR.
APPEND <FS_TAB> TO <FT_TAB>
"Here is the problem occurs, I want to grayed out the MATNR value based on some condition.
ENDLOOP.
I would like to set the 'MATNR' value to be grayed out by passing the CL_GUI_ALV_GRID-MC_STYLE_DISABLED.
and update into <FT_TAB>( <FT_TAB> structure will have 2 structures)
Finally the fieldsymbol should have two structure ( <F_TAB> = DYNAMIC STRUCTURE + LVC_S_STYLE )
Display alv grid by passing <FT_TAB> to set_table_display method.
Thanks in advance,
Kumar.

Hi,
I am not sure whether I really understand your request. Let me try to help.
> Example: <FT_TAB> TYPE STANDARD TABLE,
> <FS_TAB> TYPE ANY,
>
> DATA: INT_TAB is my dynamic table values.
>
>
> LOOP AT INT_TAB.
> ASSIGN COMPONENT 'MATNR' OF STRUCTURE <FS_TAB> TO <F_VALUE>
> <F_VALUE> = INT_TAB-MATNR.
> APPEND <FS_TAB> TO <FT_TAB>
Here <FT_TAB> must already be assigned to some internal table with a given (dynamic) structure. Did this happen before this piece of code?
What I would do is to create a dynamic table (see documentation to CREATE DATA) with MATNR and the STYLE field (LVC_T_STYL). See the documentation for CREATE DATA - creation of internal tables. When collection the field descriptions for that internal table I would also build the field catalogue for the ALV.
Then assign <FT_TAB> to that newly created internal table, <FS_TAB> to a newly created structure (same as a table line).
Move the MATNR to component 1 (or component 'MATNR') of the table and fill the style table according to your needs. Then insert the <FS_TAB> into <FT_TAB>.
Finally call the ALV SET_TABLE... method with your dynamic table and your field catalogue.

How to add deep structure like LVC_T_SCOL in dynamic internal table

Hello,
can any one help me with adding a deep structure to a dynamically created internal table. the deep structure which needs to be added is for the color purpose for each record i.e. LVC_T_SCOL .
Dynamic table created with below method.
 CALL METHOD cl_alv_table_create=>create_dynamic_table
 EXPORTING
 it_fieldcatalog = gt_struct
 i_length_in_byte = 'X'
 IMPORTING
 ep_table = dy_table.
 ASSIGN: dy_table->* TO <dyn_table>,
 dy_table->* TO <dyn_line>.
gt_struct has the list of fields and their technical attributs.
Thanks In Advance.
BR,
Rajesh

can you add a column name and attribs in gt_struct? It needs to be declared like:
<colorcolumnname> type lvc_t_scol.

Read Table with Key in a Deep Structure

Hello,
I'd like to read a table while comparing a value in a deep structure. So in the following code the key ID is a deep structure within cs_purchase_order_message-purchase_order-item-value.
For some reason code check returns no errors with the following code, but I get a short dump with a syntax error on id-value when I execute the code.
read table cs_purchase_order_message-purchase_order-item assigning <fs_xml_item> with key id-value = <fs_item>-number_int.
How do I use "with key" when the value is in a deep structure?
Thanks,
Matt
