How to insert line with values in ALV (CL_GUI_ALV_GRID)?

Hi,
Does anyone know how to get control of new line inserted in ALV (I am using class CL_GUI_ALV_GRID) before the new line is shown to the user. What I want the user to see is not a completely blank line, but a new line with certain fields filled with data.
I have tried with ALL events in CL_GUI_ALV_GRID but without any luck. If I create my own user command and insert it in the alv menu I get control, but not with the standards. Why?
Please help
Kind regards - Keld Gregersen

The document contains no posting lines with value other than zero

Hi!
We are having problems posting a invoice in MIRO. When entering the PO number we receive the error message "The document contains no posting lines with value other than zero".
What could be the problem?
/Anders

Hi!
The GR_BASEDIV is set in the PO. The PO is replicated from SRM where this flag has been set for no reason. Only GR and IV are set and we have implemented a note 1155266 so that Confirmation-Related IV will not be set.
How come it is set anyway?
Sincerely
Anders

How to insert line number into APPLIED_CUSTOMER_TRX_LINE_ID?

Hi All,
I am working on the table of receivable AR_RECEIVABLE_APPLICATIONS_ALL.
I get some information about APPLIED_CUSTOMER_TRX_LINE_ID form TRM.
APPLIED_CUSTOMER_TRX_LINE_ID NUMBER (15)
The line number of the debit item or credit memo to which a payment or credit memo is applied
So, I want to use APPLIED_CUSTOMER_TRX_LINE_ID to join with transaction's line (RA_CUSTOMER_TRX_LINES_ALL).
But after applied the credit memo, the APPLIED_CUSTOMER_TRX_LINE_ID is NULL.
How to insert line number into APPLIED_CUSTOMER_TRX_LINE_ID?

Hi Eric,
The application is already at the AR Invoice (header) level. Oracle doesn't give you privilege to apply the invoice at invoice line or distribution level. You need to match the applied_customer_trx_id to customer_trx_id of ra_customer_trx_all to get the applied invoice/debit memo number. Hope my comments are helpful to you.

How to insert check box value in table?

Hi all
kindly help me how to insert check box value in database. what code i have to use as i am new in programing.
thanx in advance

Hi,
There is no "Check box" in a table, a check box is a GUI (Graphical user interface) item.
What you want is to store a boolean value in a table. For that you can use the varchar2(1) datatype and store Y or N. (or anything else)
(you cannot define boolean as a datatype for a column).
If you're using a front-end application like apex then it might be useful for you to read the documentation about chekc boxes :
http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10497/check_box.htm#CHDDFBFH
(for the rest if it's Oracle Forms then everything is already said).

How to insert date with timestamp into table values

hi,
I have a table
create table abc1(dob date);
insert into abc1 values (to_date(sysdate,'RRRR/MM/DD HH24:MI:SS'))
but when i see in data base it shows as normal date without time stamp.
Is it possible to insert into back end with timestamp.
Thanks..

First, SYSDATE is a DATE already, no need to convert it to a DATE using the TO_DATE() function.
The date ALWAYS has a time component, whether or not it is displayed is up to your NLS settings. for example:
SQL> CREATE TABLE ABC1(DOB DATE);
Table created.
SQL> ALTER SESSION SET NLS_DATE_FORMAT='MM/DD/YYYY';
Session altered.
SQL> INSERT INTO ABC1 VALUES(SYSDATE);
1 row created.
SQL> SELECT * FROM ABC1;
DOB
02/04/2010
SQL> ALTER SESSION SET NLS_DATE_FORMAT='MM/DD/YYYY HH24:MI:SS';
Session altered.
SQL> SELECT * FROM ABC1;
DOB
02/04/2010 12:54:57
SQL> DROP TABLE ABC1;
Table dropped.

How to insert a specific record into alv

Hi everyone,
here is my problem:
    I put an ALV GRID control in my screen , it display some records.
    and I create a new button on the toolbar, and in the "handle user command class" , I need to
select a record from DB table into a work area.
    after I select the record I need, here is the key question:
      *I want to insert the record into the ALV at a specific row position which the user decided,
what should I do?*
METHOD HANDLE_ON_USER_COMMAND.
    CASE E_UCOMM.
      WHEN CL_GUI_ALV_GRID=>MC_FC_LOC_INSERT_ROW.
      WHEN 'FC_ASSIGN'.
***I do some selection here
        select %%%$$%%%^&&** into GS_HOLIDAYS.
*** after the selection, what should I do then????
*** I want to insert the work area GS_HOLIDAYS into ALV at a specific position
*** e.g. into the 3rd row.
*** how can I achieve that????
***call a method or something??????I don't know
      WHEN 'FC_DELETE'.
      WHEN OTHERS.
    ENDCASE.
ENDMETHOD.
pls don't let me go through the programs in package "SLIS",because I have already done that and
I haven't solved my problems yet.
Thanks for your help.

All u need to do is on user command for inserting new records u just insert a blank record in your internal table that u are displaying with required style informaion for making it editable and then refresh alv display by method REFRESH_TABLE_DISPLAY.
Thanks & Regards,

How to insert line or row in a table?

Hi OAF experts,
can anyone show me how to insert row or line in a table bean by setting the table.setAutoInsertion(false) ?
Thank you.
Jon

As per Dev Guide:---
The other change you can make is to suppress the default Add Another Row button behavior of adding a
single row to the view instance associated with the table, so that you can handle the event with your own code.
The following code example illustrates how to accomplish this:
processRequest
// Enabled add row and turn off the default "Add Another Row" table event
// The add row event has to be auto-handled by developer in processFormRequest
tableBean.setInsertable(true);
tableBean.setAutoInsertion(false);
processFormRequest
if ((tableBean.getName()Equals(pageContext.getParameter(SOURCE_PARAM))) &&
(ADD_ROWS_EVENT.equals(pageContext.getParameter(EVENT_PARAM))))
OAApplicationModule am = pageContext.getApplicationModule(tableBean);
am.invokeMethod("handleInsertRow", null);
// The ***AMImpl.java in which method "handlInsertRow" has been defined
public void handleInsertRow()
OAViewObject vo = findViewObject("voName");
vo.invokeMethod("handleInsertRow");
// The ***VOImpl.java which is associated with the table; and in which the
// handleInsertRow is defined
public void handleInsertRow()
Row row = createRow();
// Set any default attributes
row.setAttribute(...);
// Insert the row into the VO
insertRow(row);
Thanks

How to insert into default values in onli 1 column of a table

if u create a table with onli 1 column
which can accept a default value of say
only 100.
then how do u actualli enter values into the table.
is there any data dictionary which stores details about default
values of a table

The default value for a column is the value that will be stored
for that column if you do not provide one in your insert
statement. If you do provide a value, then it will be stored in
the column.
You can query user_tab_columns ( or all_ or dba_)to see the
default value assigned to a column.

How to change sub total value in ALV Grid.

Hi All,
Can u please explain how to change SUBTOTAL Value in ALV Grid display based on another field value.
EX; F1 subtotal is initial then we have to modify the F2 sub total to 9999.9.
Thanks
Radha.

Hi Radha,
I doubt if that can be changed....because the event that i was referring to in my previous post works with ALV List display...But in any case you can try that.....
There is an event in SLIS....(As i told you, i dont remember the name and currently i dont have access to SAP system, so i am not able to verify and let you know that event name).....
Other thatn TOP and END of PAGE events, there is an event for sub-total text......i think it would start with "SUBTOTAL"...
you need to use that event in your events table and pass it to ALV Grid display.
Then create a sub-routine with that name (As you do for TOP-OF-PAGE event)....and in this event you can change the values in runtime (PROVIDED, this event gets triggered for ALV GRID).....
If this does not work, i think calculating sub-totals while you build the internal table would be a better option....(If you have time constraint....else you can do some more research on the same)........
Best Regards,
Ram.
