Finding Dynamic no of Fields

Hi All,
I have a attendance Internal Table of Employees. This internal table is in following format.
Emp ID Date Project Hrs
Now an Employee can have any no of records per day and can book into different no of Project by dividing the no of hrs per day.
Now my requirement is i need to display Output in one line item for each employee for the data in attendance Internal table in the following manner.
EmpID Project1 Hrs1 Project2 Hrs2... ProjectN HrsN.
Here i am facing the problem in finding out the maximum no of Projects as it should be dynamic depending on a particular emp assigned to maximum no of projects.
Please do the needful help..If any Clarification in the Post Plese reply.
Thanks

Hi Shashikanth,
You can do like this. lets say you have your employee table in this reference lref_emp_tab.
DATA: lref_struct   TYPE REF TO cl_abap_structdescr,
           lref_emp_tab TYPE REF TO data,
          ls_emp_wa TYPE REF TO data,
         lv_line TYPE i.
FIELD-SYMBOLS:
    <fs_tab>      TYPE STANDARD TABLE,
<fs_wa>       TYPE ANY.
ASSIGN lref_emp_tab->* TO <fs_tab>.
CREATE DATA ls_emp_wa LIKE LINE OF <fs_tab>.
ASSIGN ls_emp_wa->* TO <fs_wa>.
lref_struct ?= cl_abap_typedescr=>describe_by_data( <fs_wa> ).
DESCRIBE TABLE lref_struct->components LINES lv_line.
Now lv_line has number of coloumns in your internal table.

Dynamic assign in field symbols

dynamic assign in field symbols

Hi,
DYNAMIC ASSIGN:
If you do not know the name of the field that you want to assign to the field symbol when you write a program, you can use a dynamic ASSIGN statement:
ASSIGN (<f>) TO <FS>.
This statement assigns the field whose name is contained in the field <f> to the field symbol <FS>. You cannot use offset and length in a dynamic ASSIGN.
At runtime, the system searches for the corresponding data object in the following order:
If the ASSIGN statement is in a procedure, the system searches first in its local data.
If it cannot find the object in the local data (or if the ASSIGN statement is not in a procedure), it then looks in the local data of the program.
If the field does not exist in the global data of the program, the system looks in the table work areas declared with the TABLES statement in the main program of the current program group. A program group consists of a main program and all of the programs that are loaded into the same internal session as a result of other program calls.
If the search is successful and a field can be assigned to the field symbol, SY-SUBRC is set to 0. Otherwise, it is set to 4, and the field symbol remains unchanged. For security reasons, you should always check the value of SY-SUBRC after a dynamic ASSIGN to prevent the field symbol pointing to the wrong area.
Searching for the field in this way slows down the program. You should therefore only use the dynamic ASSIGN statement when absolutely necessary. If you know when you create the program that you want to assign a table work area to the field symbol, you can also use the following variant of the dynamic ASSIGN statement:
ASSIGN TABLE FIELD (<f>) TO <FS>.
The system then only searches within the table work areas in the main program of the current program group for the data object that is to be assigned to the field symbol. This addition is forbidden in ABAP Objects, since the latter does not support table work areas.
Suppose we have three programs. The main program:
REPORT demo_field_symbols_dynami_as_1.
TABLES sbook.
sbook-fldate = sy-datum.
PERFORM form1 IN PROGRAM demo_form1.
The other two programs are:
REPORT demo_form1.
FORM form1.
PERFORM form2 IN PROGRAM demo_form2.
ENDFORM.
and
REPORT demo_form2.
FORM form2.
DATA name(20) TYPE c VALUE 'SBOOK-FLDATE'.
FIELD-SYMBOLS <fs> TYPE ANY.
ASSIGN (name) TO <fs>.
IF sy-subrc EQ 0.
    WRITE / <fs>.
ENDIF.
ENDFORM.
The output looks something like this:
02.06.1998
The program group in the internal session now consists of the programs DEMO, MYFORMS1 and MYFORMS2. The field symbol <FS> is defined in MYFORMS2. After the dynamic ASSIGN statement, it points to the component FLDATE of the table work area SBOOK declared in the main program DEMO.
REPORT demo_field_symbols_dynami_as_2 .
TABLES sbook.
DATA: name1(20) TYPE c VALUE 'SBOOK-FLDATE',
      name2(20) TYPE c VALUE 'NAME1'.
FIELD-SYMBOLS <fs> TYPE ANY.
ASSIGN TABLE FIELD (name1) TO <fs>.
WRITE: / 'SY-SUBRC:', sy-subrc.
ASSIGN TABLE FIELD (name2) TO <fs>.
WRITE: / 'SY-SUBRC:', sy-subrc.
The output is:
SY-SUBRC:      0
SY-SUBRC:      4
In the first ASSIGN statement, the system finds the component FLDATE of the table work area SBOOK and SY-SUBRC is set to 0. In the second ASSIGN statement, the system does not find the field NAME1 because it is declared by the DATA statement and not by the TABLES statement. In this case, SY-SUBRC is set to 4.

In Report Painter, need to find out how a field is defined.

I'm trying to find out how a field used in a current report is defined. For example, columns 2-13 are monthly columns. Double clicking on the column name (April), for example, brings up the box "Element Definition: April;$Year. The Value Field is Net Sales. Clicking the drop down box brings up a group of fields, including Net Sales.
The Field Name for Net Sales is MA0001. How do I find out how this field is defined and what accounts are included in it?
Thanks for any help you can give.

Hi,
Thank you for your answer. I was able to track 'Net Sales' as a part of a Key Figure Structure and as an element of Key Figure 'Net Sales'. However, when I get into CO-PA, Information System, there is no line for 'Report Components'.
There are the following lines/folders: Display Line Item List, Define Report,Current Settings, Background Processing. I looked at all the possibilities in those line items/folders and nothing was there. Is there another way to get at it?
Thanks again.

How to get the co-ordinates of a dynamically created input field

Hello Frn's
i have created a dynamic text view . but this text view is not appearing at proper position . I want palce it infront of a dynamically created input field . how can i do this ?
as i am thinking ...i should first of all get info about the co-ordinates of dynamaclly creatd input field . and with respect to these co-ordinates ...set the position of text View .
Please suggest your thoughts .
Thanks and Regards
Priyank Dixit

Hi,
There is no provision in WD for getting screen coordinates and then placing the UI element.
You to add the UI element to layout editor and based on the layout type it will add the UI element to respective position.
I would advice not to create dynamic UI elements( instead you can create them statically and then play with visibility status through context binding ). This will be more effective way and less error prone. This is also recommended practice.
still,For dynamic creation you can refer to following wiki:

How do I find what table a field is in?

Hi,
If I know a field name, how would I search the Data Dictionary to find the table (or tables) that the field is found in?
For example, I have a program spec that that says field AZSUB is in table MARM, but it is not. How can I find what table this field is actualkly in?
Thanks for your help!
Andy

Hi Andrew,
Just goto se11, enter the data element of that field and clisk on the where used list on the application tool bar. You will get all the tables in which the field appears.
You got find out which would be your appropriate table may be using by the description of the table or the contents or by the links..

How to find where the screen field is stored in table

Hi all,
How to find where the screen field is stored in the table .
for some transactions if i press F1 on the field and after checking for the technical help.
I can only find the struture for the screen field, but whereas i need table name for it.
Can anybody help me how to find the table name where the field is stored.
Regards,
Madhavi

Hi,
Just hitting a F1 on screen field and getting structure name will not help in getting table name.
First you need to know the flow of data in the reqd module, which will help you know all the tables in that module with there most of the fields with the data flow, now you need to work on your own to figure out that in which actual tables that value is stored.
Hope this helps you.

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.

              Assign Field1 to <TS>.
                ALL_VAL-VALUE = <TS>
"After substituting the <TS> into ALL_VAL-VALUE field I need a DATA to be passed but the variable name is appending"*
         APPEND ALL_VAL.
            ENDIF.

kindly how to pass the value into the table.
Thanks in advance.

Hi,
pls assign a break point in
CONCATENATE 'WA_' WA_TABLEFIELDS-TABNAME '-' WA_TABLEFIELDS-FIELDNAME INTO Field1.
Assign Field1 to <TS>.
ALL_VAL-VALUE = <TS>
   " Put a break point here and check for the value in <TS>.
if <TS> contains value then create a work area for ALL_VAL AND PASS the Field-Symbol to that and then append thw wa into the table...
Hope this works out!!
