Ravi Kumar

I did not understand your requirement fully...but this code will give you date range for any two months..
depending up on date you've supplied...
DATA : date LIKE sy-datum,
       date_low LIKE sy-datum,
       date_high LIKE sy-datum.
date = sy-datum.
CALL FUNCTION 'MONTH_PLUS_DETERMINE'
EXPORTING
    months = '-1'
    olddate = date
IMPORTING
    newdate = date_low.
date_low+6(2) = '01'.
CALL FUNCTION 'SLS_MISC_GET_LAST_DAY_OF_MONTH'
EXPORTING
    day_in            = date
IMPORTING
    last_day_of_month = date_high.
WRITE :/ date_low.
WRITE :/ date_high.

How to validate the dates in the table control ?

How to validate the dates in the table control ?
Can I write like this ?
LOOP AT it_tab .
CHAIN.
FIELD : it_tab-strtdat,it_tab-enddat.
module date_validation.
ENDCHAIN.
ENDLOOP.
Module Date_validation.
ranges : vdat type sy-datum.
vdat-sign = 'I'.
VDAT-LOW = it_tab-STRTDAT.
VDAT-HIGH = it_tab-ENDDAT.
VDAT-OPTION = 'BT'.
APPEND VDAT.
WHAT CODE I have to write here to validate ?
and If I write like this How can we know which is the current row being add ?
It loops total internal table ..?
Bye,
Muttu.

Hi,
I think there is no need to put chain endchain.
To do validation you have to write module in PAI which does required validations.

How to validate the date in my class

Hi
In my project with jsp and struts I need to validate the date field.
So in the action class I want to validate the date that is the date is in dd/mm/year format?
can anybody please give some idea to do this?
Thank you so much.

Here is a method that validates day/month/year using the Calendar class.
     public boolean validateDate(int day, int month, int year) {
          try {
               Calendar cal = Calendar.getInstance();
               cal.clear();
               cal.setLenient(false);
               cal.set(year, month-1, day);
               // need to call getTime() to make the calendar compute/validate the date
               cal.getTime();
               return true;
          catch (IllegalArgumentException e) {
               return false;
     }

How to validate the data in the table

Hi Experts,
My question is
I am having a table control on my view. I need to validate the data entered by the user on the table
and after validation i need to save the data into database table.
Now my question is only related to Data Validation on table UI element.
If the user enters 3 rows and if the 2nd and 3rd row are already existing,
It should throw the message Entry already exists and the pointer should
be at Row number 2 in this case.
Similarly in the 2nd row i have a date field and if the user enters some character
then it should throw an error message that Numeric values are only allowed and
the pointer is placed in the 2nd row Date column so that it allows user to modify
the wrong entry.
Please advise.
Regards,
Chitrasen

Hi,
for validating user input in table , you have to get the entries inserted by user into an internal table using get_static_attribute_table and futher have your check using loop endloop.
For date field, make the context attribute binded to date column as DATS. This would make sure the user inputs a valid date without your custom code.

Function module to save the data from ALV list to MS Excel file

Hi,
I am displaying an ALV list.
I am assigning a pushbutton in the GUI status to save the list as a MS Excel file.
Can you please let me know the function module to achieve this task.
I tried 'SAP_CONVERT_TO_XLS_FORMAT' FM but it is giving some type confict error.
Thanks & Regards,
Balaji.R

ALV has this option built in, you may also find FM like [ALV_XXL_CALL|https://www.sdn.sap.com/irj/scn/advancedsearch?cat=sdn_all&query=alv_xxl_call&adv=false&sortby=cm_rnd_rankvalue].
Can you elaborate a little more on your need, why adding an option that already exits?

How to download the datas of ALV tree without passing iternal table

I want to download the values of ALV tree output in an Excel file without using any internal table.
Please suggest your thoughts on the same.

Shasiraj.C
Edited by: Raj Shasi on Aug 1, 2008 8:44 AM

There is one option -Export' in menu bar of ALV grid itself. Click on that and then click 'Local File'. Then choose 'Spreadsheet' option and provide local PC path for download.

How to fetch the data & display the data if fields got the same name in alv

hi frnds, i need ur help.
how to fetch the data & display the data if fields got the same name in alv grid format.

Refer the url :
http://abapexpert.blogspot.com/2007/07/sap-list-viewer-alv.html
Go thru the guide for OOPs based ALV.
Use SET_TABLE_FOR_FIRST_DISPLAY to display the table:
CALL METHOD grid->set_table_for_first_display
EXPORTING
I_STRUCTURE_NAME = 'SFLIGHT' Structure data
CHANGING
IT_OUTTAB = gt_sflight. Output table
You can also implement
Full Screen ALV, its quite easy. Just pass the output table to FM REUSE_ALV_GRID_DISPLAY.
For controlling and implementing the FS-ALV we have to concentrate on few of the components as follows :
1. Selection of data.
2. Prepare Layout of display list.
3. Event handling.
4. Export all the prepared data to REUSE_ALV_GRID_DISPLAY.

Please do the needful how to do it.If you want to validate at entry level then use When-Validate-Item trigger and check the input and show message. Like
If :quentity <0 then
message('do not enter negative value');
message('do not enter negative value');

How to transpose the data records (rows) to column(lists) using apd

Hi,
how to transpose the data records (rows) to column (lists) using apd in sap bw.
I do not want to use abap routine.only use the transpose rows to list transformation .
Pls provide the step by step procedure .
thanks,
Nimai

Save youe file to transpose as a csv and in the header row of your file for the columns you want to transpose you need to put some soer of a tag before the column name (ie your colum header was for a period budget will be something lie 2011001:ZFIBDD)
1. You will need to create a new apd process (rsanwb)
2. Insert a "Read from Data File" data source object and map it file (,csv)
3. insert a transpose object into your apd process (middle row 4th one over in the transformations section)
4. under the definition tab in the transformation object select all the columns that are to be transposed into rows and move them to the transformed area, the grouping fields section should contain the rows that you want to now be columns
5.under the transformation tab enter in the seperator you selected under the Field Name/Infoobject area (ie. ZFIBDD)
6. under the details tab you need to enter in all the fields to be transformed and tner the transposition field (ie ZFIBDD)
7. Then you can insert a set of transformations and a DSO and link the newly transposed fields into that.
hope that helps
