You haven't explained what object and object key you're using, nor have you provided any indication of how you implemented the GOS attachment functionality. You need to provide more information to resolve an issue like this.

How do I pass input values from a html page to a jsf page

hi,
In my project,for front view we have used html pages.how can I get input values from that html page into my jsf page.for back end purpose we have used EJB3.0
how can I write jsf managed bean for accessing these entities.we have used session facade design pattern and the IDE is netbeans5.5.
pls,help me,very urgent
thanx in advance

Simplest way is to rewrite html page into jsf page.
You can use session bean in your managed bean like this:
import javax.naming.Context;
import javax.naming.InitialContext;
public class ManagedBean {
private Context ctx;
private Object res;
// session bean interface
private Service service;
          public ManagedBean() {
            try{
                 ctx = new InitialContext();
                 res = ctx.lookup("Service");
                 service = (Service) res;
           catch(Exeption e){

How to map single input value to Two columns of Database table using format file of Bulk Copy Process

Hi All,
Am using OPENROWSET to load the file data into table, here the problem is i need to map same input value to two different columns of table, As format file doesn't allow the duplicate numbers am unable to insert same value to two columns, please help me to
find a solution for this.
i can use only OPENROWSET because i need to insert some default values also which come based on file. only the problem is how to map same input value to two different columns of table. please give me the suggestions.
Thanks,
Sudhakar

From what you say:
INSERT tbl(col1, col2)
SELECT col1, col1
FROM OPENROWSET(....)
But I guess it is more difficult. You need to give more details. What sort of data source do you have? What does your query look like? The target table?
Erland Sommarskog, SQL Server MVP, [email protected]
Hi Erland,
Thanks for your response
my source file is text file with | symbol separate for ex:
1002|eTab |V101|eTablet|V100|Logic|LT-7|Laptops|SCM
Database table have columns like
column1,column2,column3...etc, now i need to insert same value from input file into two columns for ex:
the eTab value from text file has to be insert into column2 and column3 of
table
we cannot change format file like below one
for the above situation how can we insert eTab into column2 and column3
Thanks,
Sudhakar.

How to implement line selectability for a table control using table Wizard?

Hello SDN Community,
I have created a table control using the Table Wizard. I found my exact question in this forum, but unfortunately it had not been andsered. While I cannot paste a screen-print into this plane-text area, here are the steps I followed...
1) SE51
2) Create new screen 0100
3) Click Layout button
4) Clidk Table Control (with Wizard) and draw box on canvas.
5) Step is "Start" - click Continue
6) Step is "Name of Table Control" - provided name
7) Step is "Table Name" - provided name of dictionary table (AUFK)
8) Step is "Definition of Columns" - selected order numver and order text
9) Step is "Table Control Attributes" - Line Selectability is in display mode - cannot set it.
I would like to have a selectability column for my table. Would appreciate any insight into how to do this.
Thank you,
Dean Atteberry.

This is a puzzling...
For the table control wizard, in the Table Control Attributes step, I was able to get line selectability to open up by declaring a char01 data element at the beginning of my type.
The puzzling is in regards to the "Selection col. fld" entry field.
If I leave it blank and try to go to the next step, I get message "Enter the name of the selection column if you are using a program table"
So it looked like it wanted to know the name of my selection column. So I type in "CHAR1". and got the message "The field "CHAR1" for the selection column is already contained in the table."
Hmmmmm.... don't understand............

How to add a new data element for existing table filed(Primary key field)

Hi Experts,
How to add a new data element for existing table field(Primary key field)
For this filed ther is no foreign key relation ships and even check table.
while activating table it is giving message like below.
can you help any one to solve this and wil steps to add new dataelement for existing primary key filed of a table.
Check table (NAMING SPACE/TABLE NAME(EX:/TC/VENDOR)) (username/19.02.10/03:29)
Primary key change not permitted for value table /TC/VENDOR
Check on table /TC/VENDOR resulted in errors
Thanks
Ravi

Hi,
Easiest way is to download the table eg into an Excel table (if possible) or text table. Drop the table from the database. Build your table with the new key field. Build the database table again and fill it.
You can do it also over the database into a new table. Drop the old one. Build the enhanced one and fill it. Afterwards drop your (temporary) table.
Maybe there are other ways, but this works.
Success,
Rob

How to use 'DELETE ADJACENT DUPLICATES FROM' for deleting as some field

How to use 'DELETE ADJACENT DUPLICATES FROM' for deleting as some field
eg:
I have a inner table ,it contains a field named ast_guid,now,I search ten records,contains some duplicate records in the field of ast_guid.but I can not delete the duplicate records as ast_guid.

If the type of inner table is standard table, you should sort the inner table by the fields before user 'DELETE ADJACENT DUPLICATES ', and use COMPARING addtion.

Hello body,
You can give a name such as 'SEL' in w/selcol and declare SEL as char1. Then follow the coading.
in TOP.
data: sel type c.
PROCESS AFTER INPUT.
user_command_0011.
loop at <Your internal table>.
module get_data.
endloop.
Inside Module get_data.
    if sy-ucomm = <Your Fcode>
    if sel = 'X'.
       <Your internal table>-<Field for checkbox> = 'X'.
      append <Your internal table>.
    endif.
endif.
I think your issue is resolved.

Question(s) about the Active Cell:Position property node for a table control

Hello,
What determines the Active Cell Position property node for a table control? I have this in my code and I am displaying its value to a front panel indicator. The value displayed is always set to 0,0. The help for the property node say that it is "read -only" so what sets the value of Active Cell Position for a Table Control?
Regards,
Kaspar
Solved!
Go to Solution.

You set the active cell with a property node. Once you select an active cell, you can do specific things to that cell and that cell alone, things like set the background color.

Hi,
You can use the class CL_TABLECONTROL for creating table control and the method SET_VALUES shall be used to fill values for tha tabcntrl.
Else, you can use the Table Control Wizard to create the tabcntrl easily.

How to populate a listbox with key in a table control

I have the following code:
MODULE carga_huecos INPUT.

I see that internal table li_huecos has the values I need. But vrm_set_values function is not working. I need this values to be seen in a table control field which I have defined as "listbox with key". The name of the internal table associated to the table control is "I_zmov_wm" and the field is HUECO.
After function is executed sy-subrc = 0 but no value is seen in the list.
Thanks.

hi ,
instead of this
LOOP AT estru_hueco.
li_huecos-key = estru_hueco-hueco.
li_huecos-text = estru_hueco-hueco.
APPEND li_huecos.
CLEAR li_huecos.
ENDLOOP.
CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING
id = 'I_ZMOV_WM-HUECO'
values = li_huecos[]
EXCEPTIONS
id_illegal_name = 1
OTHERS = 2.
IF sy-subrc 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
add this
data : name type vrm_id .
LOOP AT estru_hueco.
li_huecos-key = estru_hueco-hueco.
li_huecos-text = estru_hueco-hueco.
APPEND li_huecos.
CLEAR li_huecos.
ENDLOOP.
name = 'I_ZMOV_WM-HUECO' .
CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING

Coding for giving 'find' functionality to a table control field

hi.
i want to give find functionality to a table control field.when ever i will select one field & i will enter 'find' icon one modal screen comes.when i will enter one value of that field it will highlight that field in the table control.

Hi,
FIND <p> IN [SECTION OFFSET <off> LENGTH <len> OF] <text>
            [IGNORING CASE|RESPECTING CASE]
            [IN BYTE MODE|IN CHARACTER MODE]
            [MATCH OFFSET <o>] [MATCH LENGTH <l>].
The system searches the field <text> for the pattern <p>. The SECTION OFFSET <off> LENGTH <len> OF addition tells the system to search only from the <off> position in the length <len>. IGNORING CASE or RESPECTING CASE (default) specifies whether the search is to be case-sensitive. In Unicode programs, you must specify whether the statement is a character or byte operation, using the IN BYTE MODE or IN CHARACTER MODE (default) additions. The MATCH OFFSET and MATCH LENGTH additions set the offset of the first occurrence and length of the search string in the fields <p> and <l>.

Priya.
