Regarding space in grid dsiplay
Hi frnds,
I have one field involved in my alv grid display
but my problem is after display the one field its
displaying spaces which i dont want.
like
<code>
output list in grid
matnr--space--
10----
20----
30----
40----
</code>
the above space i want to delete , i only need matnr to be displayed.
regards,
sanjay
Hi Sanjay,
First you check the length of the data element of MATNR through se11 and then you define the same length into the fieldcatalog declaration....
fieldcatalog-fieldname = 'MATNR'.
fieldcatalog-seltext_m = 'Material No.'.
fieldcatalog-col_pos = 1.
fieldcatalog-outputlen = 19.
fieldcatalog-emphasize = 'X'.
fieldcatalog-key = 'X'.
fieldcatalog-do_sum = 'X'.
fieldcatalog-no_zero = 'X'.
append fieldcatalog to fieldcatalog.
clear fieldcatalog.
i hope this will help you..
Thanks & Regards

There is an space issue in datatop.Could you please help me out in deleting any logs and unnecessary data in that location.As the mount which own datatop is completely filled.
Hi,
Do you have any archivelog files on this disk? If so, consider moving/deleting obsolete files. For datafiles/tablespaces, if it is possible to shrink it, please do so. Otherwise, you need to move it to some other disk.
Also, if AUTOEXTEND is enabled, you need to disable it (at least for now) until you have more space on this disk.
You may also refer to the following document, it should be helpful.

Regarding space removal for a numeric value
Hello ALL,
I have declared a vairable in my program as
LV_amount type wrbtr.
in that filed i m passing a value as 250
hence it is taking as 250.00
but the problem is it is having some space in the front,
like ' 250.00'.
I want to remove that space, how can i do that ..
Thanks,
SureshWhen you write the Amount field it will be written as the Right Justified and put the space in front of it. You can move it to some character field and remove the space.
Check this code:
data: l_amt type wrbtr,
l_char type char20,
l_cha1 type char20.
l_amt = '123.00'.
write: / l_amt.
write: l_amt to l_char.
write: / l_char.
l_cha1 = l_amt.
condense l_cha1.
write: / l_cha1.

Just getting started with the Grid Control. Anyone know roughly how much disk space is required for a basic installation?
Some numbers can be found in the documentation :
http://download.oracle.com/docs/cd/B19306_01/em.102/b40103/pre-installation_requirements.htm
Though I use more than 2 GB for the OMS installation (AIX).

Archiving Statistics regarding space saved
I'm doing some IDOC archiving and want to know what the column headings are under the 'Display Statistics' option.
Currently I see columns for Disk Space, Disk Space Write, DB Space Delete etc.
Which one is a fairly accurate display of what I have saved in terms of space within the table?
Is it the (Write) columns or the (Delete) columns?Hi,
It's the DB space (Deleted) which tells you that this much amount of space have been freed up after you have archived the IDOCs or R/3 data.
DB space (written) will tell you the number of objects written for archiving but not yet removed from the SAP R/3 database. The delete program tells you the accurate information as it compares the written objects wtih the saved objects on the storage system and the sap database.
Thanks,

Regarding spaces in the last in of TXT file in the outbound interface
Hi ,
I am doing one outbound file, which will have 100 characters length, But last 25 characted i have to fill spaces. When i m trying to fill those 25 chatacters with spaces its not working, i tryed by creating a variabnle of 25 chracted space, still it is not working. Here below i gave the example program....
data: wa_detailed(100) type c.
wa_detailed+0(1) = 'suresh'.
wa_detailed+70(5) = 'welcom'.
wa_detailed+75(25) = ' ',.
append wa_detailed into ist_download.
This is my program, i m unable to fill those spaces.
can any one respond asap.
Thanks,
SureshIt may not be possible to append spaces in any of the variable. E.g. if you look at write statement, it does not allow us to write spaces. Instead, you can have an end of file character like '$' which is placed at 101st position. Look at the below code:
wa_detailed+0(1) = 'suresh'.
wa_detailed+70(5) = 'welcom'.
wa_detailed+100(1) = '$'.
This way you can transfer first 100 characters to the outbound file.
Let me know if you have any further queries.
Don't forget to mark helpful answers!

Regarding space not released after rm commend on root
hello guys
actually i am facing an unexpected problem
i have a folder /archivelog which is mounted on ocfs.daily i used to store my export file here.But yesterday i started taking exp from one terminal with file=28june.dmp and after starting it removed previous day export from other terminal with file=27june.dmp.
But i have seen something different.
i fired rm -rf 27june.dmp it returned the root prompt immediately though daily to remove a 60 gb file it taken 30-40 seconds.
also it didn't released the spcae from /archivelog and also removed the file
means its not listing the file and also the space is not released ...i also fired command updatedb..but still the space is not released.
hoe could this be possible..anyone has any idea so kindly tellThere is a bug with ocfs2 if you delete archive logs manually some time will not freee the space which is used. So for future to avoid this case use rman to delete archive logs.
now to free space need ocfs2 partition to delete and create again with ocfs2. becarefull with this.

Regarding Oracle 10g Grid Control Enterprise Manager
Hi Friends,
the file at http://www.oracle.com/technology/software/products/oem/htdocs/winsoft10g.html
Named B30800-01.zip is having a problem.
As I had downloaded the file with the (download manager and Directly also), but after downloading file size is been matching and there was no error with the download of the file.
Downloaded File Size = 1729778063 Jul 13 07:44 b30800_0.zip
But at the time of getting extract the file has been given many errors.
Can anyone tell me what should I do?
As I had tried to send a mail with extraction report to Oracle Corporation email id but I got a failure Delivery.
Can anyone give me the email id of oracle corporation where I can get some help from Oracle Corporation.
Thanks in Advance

Bhavik FuletraHi,
Dear lavaprasadkafle,
Size and size on disk usually differs
The Size is the real size of the file,
The file system stores data in clusters of certain size (Usually 4k bytes in NTFS, 8k or 16k in FAT32), so if you have a file with size 250 bytes on NTFS 4k, Size on disk will be 4 k (4096 bytes), with FAT32 at cluster size 16, the size on disk will be 16384 bytes!
For the file you mentioned, I guess that it is stored on FAT32 partition with 16k cluster size, just calculate it as previously done, you will find where 11889 bytes came from.
On the other hand, to make sure that the zip file is downloaded correctly, just open and test it with any archive tool that have test. or you can use MD5 or any other hashing check.

Hi !!!
I'm using an ALV Grid object with set_table_for_first_display.
Is it possible in a ALV Grid control, to enable or disable some cells (with checkboxes, but not the entire column, just some cells) ... ? By updating the field catalog ?
I want to do this after an authorization control ...
Thanks

Should I have spaces between paragraphs or paragraph indents?
I am creating a pdf interactive document/ebook, and am wondering whether to use a space between paragraphs or use indents. Is there a standard?
dopfel wrote:
Scott Falkner wrote:
It is entirely up to you. Use one or the other, but not both. If you are using paragraph Styles it is easy to make a global change and see which reads better. Generally, I prefer spaces to indents. The space should be either one line of lead (i.e. equal to the paragraph’s leading value) or half a line of lead if one full line looks to large.
My reply is in reference to the above quote regarding how to make a
global change so that all of the paragraphs in the document have spaces between them w/o having to select each and every paragraph and applying the 'paragraphspacing' style.
How do I go about this ?
Format a paragraph as you want all similar paragraphs to look. Now go to the Paragraph Styles panel and create a new Style. Right-click on the new style to edit the style and give it an intuitive name. Now you can format any text the same way by first selecting the text, then clicking on the style in the Paragraph Styles panel. If you later want to change all of the paragraphs using that style, just right-click on the style and change any attributes to globally change all paragraphs in the document using that style.
secondary: not certain the below applies to my question regarding spaces between paragraphs and changing them globally.
i have also found and wondered about using the setting for the 'align to grid' where default is none and options are
'all lines' or 'first line only'. Does this apply in any way to a regular layout of a 'novel' ?
i do not know what this refers to.
The space should be either one line of lead (i.e. equal to the paragraph’s leading value) or half a line of lead if one full line looks to large.
thanks again.
Leading is the term for the space from the baseline of one line of text to the baseline of the next line within a paragraph. The default is “Auto”, which is 120% of the point size. For 12 point text, Auto equals 14.4 point leading. First: Don’t use Auto leading. Change the leading of your style to a number. About 120% is as good a place to start as any, but it depends on the typeface. You may decide to use 11 point text on 14 point leading.
Because you will have columnd of text next to each other on the page, or pages of text neext to each other on a two-page spread, you want to make sure your text lines up neatly in columns or pages (although for pages it is less critical). The easiest way to do this is to use paragraph spacing equal to your leading, i.e. 14 points. This way, no matter how many paragraphs (and thus, blank lines between paragraphs) you have, the text will always have a heigh that is multiples of 14 points, so bottom baselines will always line up.
You may decide that looks like too much space, and want to use a lower value. The next best value is half the leading, or 7 points. That way, about half of the time your columns or pages will line up and the bottom baselines will sync.
Once again, it is ultimately up to you how you want the text to look and how you want your pages or column to look next to each other. If 14 (or whatever your leading is) looks too small or 7 (or whatever half the leading is) looks too big, then go with what looks best. Always try to keep an eye on the big picture, though. Don’t just look at one line of text, look at the entire paragraph. Don’t just look at one paragraph, look at the column. Don’t just look at one column, look at the page. Don’t just look at one page, look at the spread. And always keep the reader in mind. You are designing the document for the reader, not for yourself.
