Can anyone tell me How to populate system date & time when user enter data for custom table in sm30..
Req is
i have custom table and using sm30 user can enter data.
after saving date i want to update date & time in table
Pls let me know where to write the code?
Thanks in Advance

You have to write the code in EVENT 01 in SE54 transaction. Go to SE54, enter your Ztable name and in the menu 'Environment-->Events'. Press 'ENTER' to go past the popup message. In the next screen, click on 'New Entries'. In the first column, enter 01 and in the next column give some name for your routine(say UPDATE_USER_DATE_TIME). Then click on the souce code icon that appears in blue at the end of the row. In the code, you need logic like below.
FORM update_user_date_time.
DATA: f_index LIKE sy-tabix.
DATA: BEGIN OF l_total.
          INCLUDE STRUCTURE zztable.
INCLUDE STRUCTURE vimtbflags.
DATA END OF l_total.
DATA: s_record TYPE zztable.
LOOP AT total INTO l_total.
    IF l_total-vim_action = aendern OR
       l_total-vim_action = neuer_eintrag.
      MOVE-CORRESPONDING l_total TO s_record.
      s_record-zz_user = sy-uname.
      s_record-zz_date = sy-datum.
      s_record-zz_time = sy-uzeit.
      READ TABLE extract WITH KEY l_total.
      IF sy-subrc EQ 0.
        f_index = sy-tabix.
      ELSE.
        CLEAR f_index.
      ENDIF.
      MOVE-CORRESPONDING s_record TO l_total.
      MODIFY total FROM l_total.
      CHECK f_index GT 0.
      MODIFY extract INDEX f_index FROM l_total.
    ENDIF.
ENDLOOP.
ENDFORM.                    " UPDATE_USER_DATE_TIME
Here ZZTABLE is the Z table and ZZ_USER, ZZ_DATE, and ZZ_TIME are the fields that are updated.

How to find login times greater than 24 hours from custom table.

Hello Guru's,
I am having trouble approaching how to construct a query that will find who has been logged in for more than 24 hours, this table is updated every few hours to show who's logged in and where- I am attempting to find out if someone has been logged in for more than 24 hours- if so, who and where. This is difficult for me because I need to compare each recorded for each user login and then see if the next entry is greater than 24 hours from the previous entry.
A table holds the login times and locations as table position_hist:
position_id,userid,upd_date.
Something like;
select position_id,userid,upd_date from position_hist where (select upd_date from position_hist where "the next entry for that user and that position is greater than 24 hours?????"
I guess the easier way to look at it is for a given position_id who has been logged in for more than 24 hours in one go.
Any advice would be brilliant :-)

It's hard without knowing your Oracle version, or having any sample data to work with. Please post that in the future using \ tags and DDL/DML.
Here is what I came up with as a guess:SQL> WITH POSITION_HIST AS
2 (
3 SELECT 1 AS POSITION_ID, 1 AS USER_ID, TRUNC(SYSDATE) AS UPD_DATE FROM DUAL UNION ALL
4 SELECT 1 AS POSITION_ID, 1 AS USER_ID, TRUNC(SYSDATE)+1 AS UPD_DATE FROM DUAL UNION ALL
5 SELECT 1 AS POSITION_ID, 1 AS USER_ID, TRUNC(SYSDATE)+2 AS UPD_DATE FROM DUAL UNION ALL
6 SELECT 1 AS POSITION_ID, 1 AS USER_ID, TRUNC(SYSDATE)+4 AS UPD_DATE FROM DUAL UNION ALL

Autofill date/time when entering data?

Hi,
I'm new to Numbers so still learning the ropes, but...
I have made a call log which should automatically enter the date and time when I enter data into a 'Notes' field. This works for the first instance but when a new call is received and I add a new note the date and time changes for all previous notes.
The formula I am using is as follows:
IF(ISBLANK(F3),,NOW())
I have tried to attach the numbers file bu struggling to see how so I've attached a screenshot which might be of use.
Any help greatly appreciated!

the function now() atucally returns now. That is... the date and time it is at the very moment the function is called. You are asking for a timestampt. The best way to implement a timestamp (which technically Numbers DOES NOT HAVE) is to keep a single cell table in a handy place (I keep it in the top left corner), then put the formula:
=now()
in the single cell.
When you add a new entry, select that single cell, copy, then paste formula result.
this can be done quickly when you memorize the key combinations:
copy = <command> + c
paste fomula result = <command> + <shift> + v
You can make suggestions to Apple using the menu item "Numbers > Provide Numbers Feedback"

How to use User entered dates in intreval

Hi,
User will enter date range in variable
As per my requirment i want to use no of days between those 2 user entered dates in my calculaction
How can i achieve this at report level.
Thanks

Hi
Create a variable with intreval.
There is a function module which calculates the no of days between the days
Go to SE38 and ZXRSRU01 Program
Write the Code like this (Not exact code) you can modify
WHEN "ZZZZZ"(Before that create a formula variable to get the number of days between the days and use the tech name of the formula variable here)
read ..the lower limit and the upper limit of the caldaz variable
FROMDATE = L_S_RANGE-low
TODATE = L_S_RANGE-HIGH
Then call the function module
Search for the function module by using days in SE37
Then pass the from and to Date to the function module it will retun the number of days
update that to table e_T_Range
You can proceed with this

How to handle user entered data validation

Hi,
In my page i have three fields
Empname (String)
Empnumber (Number)
DOB (Date)
These fields are mapped to VO which are mapped to EO.
When user enters string in Empnumber field then it will throw user following Error "Cannot create an object of type:oracle.jbo.domain.Number with value hghfg"
I want to display above Error in user friendly fashion.
Where to do this and How to do this?
And i have one more question
can we handle all the exceptions in seter method of EOIMPL?
-Thanks
Mithun

Sumit,
I have set 'Disable Client Side Validation' in the property inspector true for submit button. Added below code for validation
In CO
String lb_flag= (String)am.invokeMethod("validateRVSize",prm1,prmType1);
In AM
public String validateRVSize(String val)
String values = "1234567890' ";
for (int i=0; i < val.length(); i++)
if (values.indexOf(val.charAt(i)) < 0)
return "false";
return "true";
but what i have observed is control is not at all coming to process form request. it is doing it's validation in processformdata itself, i suppose.
because no statement is getting printed if i had entered characters in number field.

Calculate one month prior to user entered date by a Date/Time field

Hi All,
I am currently pretty new to Live cycle and have no idea about Java scripting, i have been using this site a lot for my forms and have used the FormCalc for expanding tables and so on but this one is proving difficult. I am currently designing a form that requires a calculation of one month prior to a user entered date by a Date/Time field. I have looked at multiple posts on how to do this but none have worked (they are using the Date2Num).
Is anyone able to enlighten me please?
I currently have:
Date/Time field Date Due
Date/Time field Planned Date of Review
I need Planned Date of Review to be calculated to be 30 days prior to Date Due. How do I go about doing this? Is it incorrect to use a Date/Time field as the field type for the calculation?
Cheers
Brad

You can use FormCalc to compare the user input.
Put this script into the exit:Event of the date field.
if (Date2Num($.formattedValue, "MM/DD/YYYY") ne date()) then
$host.messageBox("The entered date is not todays date!")
endif

How can I read the last cell of a JTable that a user Enters data

I have a one column JTable with several rows that a user enters data to. Upon entering the last data, the user clicks a button to read all the data from the rows in the JTable and puts them in an arraylist. If the user does not click enter or navigates away from the last cell, then after clicking the button it does not read the last cell entered. Since the user is clicking on a button to indicate he is done entering data on the table, does he also have to hit the enter key to indicate he is done entering the data?
The code below is my tablemodelListener:
public class InteractiveTableModelListener implements TableModelListener {
public void tableChanged(TableModelEvent evt) {
if (evt.getType() == TableModelEvent.UPDATE) {
int row = evt.getFirstRow();
System.out.println("Update row:"+" "+row);
jTable1.setRowSelectionInterval(row, row);
}

Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.
In the future, Swing related questions should be posted in the Swing fourm. (This question has been asked and answered dozens of times).
But there is not need to repost because [Table Stop Editing|http://www.camick.com/java/blog.html?name=table-stop-editing] explains whats happening and give a couple of solutions.

How to get the user entered data?

Hi all,
I have created an HTMLB DynPage component.
In That i have created my input screen with textboxes using response.write method.
i have added one onConfirm event on which the data whould validate.
so onConfirm method im trying to get the data with request.getParameter method which returns null...
how to do...how to get the user entered data to do my validations...can anyone plz advice.
Thanks,
Viswes

Hi
inputfield or textbox component entered directly using response.write(...) are not htmlb , but html.
to create portal input field (ie HTMLB), you should do something like
this in the doProcessBeforeOutput member function
InputField field1 = new InputField("Id1");
field1.setSize(8); // 8 characters
this.getForm().addComponent(field1);
and in doProcessAfterInput member function
InputField field1 =
(InputField) this.getComponentByName("Id1");
you can then manipulate the content of the field.
Hope this help,
Guillaume

To compare two user entered dates

HI FRIENDS
here is my code.

Judging from your code, you've got a lot of learning
to do. I suggest you
split it up:
1. Write non-GUI code that attempts to parse, compare
and format dates.
2. Write simpler GUI code to capture ordinary
strings, for example, and
worry about dates after you can do something simpler.And standard instructions: Use code tags.

How to populate the time component of a cube?

We have a question regarding how to populate the time component of a cube. Let me explain:
We are using OWB 10gR2. We have created a cube with several dimensions. We are now building the mapping to load the cube. The cube operator has two columns for every dimension (e.g., "customer" and "customer_id" for the "customer" dimension).
We understand that, in this case, "customer_id" stands for the dimension business key, so we create an arrow from the business key in the source table to the "customer_id" column in the cube operator.
So far so good. The mapping works all right, and the cube is loaded correctly.
Now we need to do the same for the time dimension. We have already created the time dimension and we have loaded it. We have also included it in the cube, so now we have two new columns in it: "time_day_code" and "time", both NUMBER data type.
We have the "sale_date" column (DATE data type), in the source system and, of course, now we want to populate the date column in the cube. We suppose that, somehow, we have to translate the "sale_date" field into the numeric column of the surrogate key of the time dimension. How should do we do this? I suppose that OWB must do the translation for us, just as it does for the other dimensions, but how? We have been looking into the manuals, and we have found no explanation on how to go about this.
Any help would be appreciated.
Best regards
Juan Algaba

Hi Juan
You are right this should have been in the manuals, checked and there is only a brief mention (Using a Time Dimension in a Cube Mapping section)
The identifier format should have been documented for each level and will involve creating the formatted attribute for input to the cube operator's time dimension reference attribute.
The time dimension business keys are stored as follows;
Day Level - YYYYMMDD
Month Level - YYYYMM
Week Level - YYYYWW
Quarter - YYYYQ
Year - YYYY
If you have a source that has a SQL date datatype for example and want to construct the key for a cube's time dimension at the day level something like the following expression can be used to construct the time reference from a SQL date...
to_number(to_char( time_key, 'YYYYMMDD'))
The result of this expression can be used as input to the cube's time dimension attribute.
Cheers
David

Cell data not getting refreshed in which user enters data OO ALV(editable)

Hi Friends,
I am using OO ALV for editable grid display.
I am unable to change grid data in the cell in which user enters something, using OO ALV. Did through debugging of my own program and found that some problem with system program. Then I did all system debugging. Could not find out why is the grid not getting refreshed with the new data in the cell in which user had entered some value. Rest of the cell's data are getting refreshed with the values which i am updating in the final internal table. I can see that the data in the final internal table is changed for the cell in which user enters data. But even after the call of
      CALL METHOD obj_alvgrid1->refresh_table_display
does not refreshes the data in the cell in which user had entered data. Rest of the cells data are getting refreshed.
Piece of code:
SET HANDLER obj_event_receiver->handle_data_changed

                                             zascas modif.
User enters data in zascas field. Based on the data entered, I am changing other fields which is getting refreshed. I am also changing zascas in the program even after user had already entered the value which was bit wrong and i am correcting it in the program on the even "data_changed" even.
Please help me friends as i m strugling past hours wondering why the data is not getting refreshed for the cell in which user enter data.
Regards,
Surya

Hi Surya,
   The approach you are following is correct. You need to use the comibnation of all these things:
Event - DATA_CHANGED
Methods - CHECK_CHANGED_DATA
             - GET_CHANGED_DATA.
However, here are few standard programs which are having similar functionality.

Note however that the concensus among the wise is that accurate "logout" statistics with APEX (or any browser-based system) is impossible. How many users actually logout using using a method that triggers a capturable event at the actual time they stop using the system? How many are going to close the current browser tab? Or the entire browser window? Or press Cmd-Q? Or click a bookmark for a different location? Or type "p0rn" into the Search box? Or switch to another window and spend the rest of the morning reading Twitter? Or shutdown the machine? Or run out of battery power? Or lose their wifi connection? Or get timed-out during the fire drill? Or go home for the night after locking their PC with everything still running? Or...
