Regarding Reading contents in classical ALV

Hi Experts,
I have a problem in Classical ALV Grid Display.
I donot know how to read the contents of modified fields after the grid is displayed.ie. i will modify some cells and press a button which is defined by me then the modified contents need to be read and updated in the data base.i am not able to read those modified contents.so please help me.i am using REUSE_ALV_GRID_DISPLAY.that is my requirement.i cannot use ALV Objects.i am posting the code.please verify and help me.

Hi
I sure that there is a better way,but this one will work also...
In PBO enter rows you will show in report to itab you define (same type)
In PAI (after change) compare this tables (your grid table and itab with values before the change) and you will get rows which have been changed...

ALV GRID Problem with reading contents

Hi there! I'm quite new with ABAP and I have some problems with the syntax of it. Maybe I should first describe my aim and then I'll show you my code.
1. I read contents from two database tables, called 'zbc_dan_registry' and 'zbc_dan_category'.
'zbc_dan_registry' has 2 columns: name, value.
zbc_dan_category' has 1 column: category.
Now I want to have an ALV Grid, that displays the contents of 'zbc_dan_registry' and one additional column with dropdown fields, where the user can select a category for each row. This is, what my code already does.
Now I want to save the contents of the whole table in a new table 'zbc_dan_registrz' (you see: 'registrz', not 'registry'!) with 3 columns:
name, category, value.
My problem is, how can I read the contents of the ALV Grid, with the user selected category for each row, and save them in an internal table? I've tried to adapt the code of "BCALV_EDIT_04", but I don't get it running.
Some detailled help would be great, you know, I'm really working hard to understand ABAP, but it's really hard for me. Thanks for your support and help!!
Here's my code so far:

Ipod classic music erased, with "iTunes cannot read contents of iPod"

I went to sync my ipod classic 120GB and before it began, a message popped up telling me that there was a problem with my devices and that they should be scanned and fixed. I went to scan and fix them, but it failed each time. It started syncing but then an error message came up saying, "iTunes cannot read contents of iPod, go to summary tab in iPod preferences and click restore to restore this iPod to factory settings. I took my ipod out of the usb cable and looked to see that my music had all been erased! I went to the preferences tab that it told me to go to and if I restore the iPod to factory settings then all my media will obviously be erased. I have tried a few times since then to re-sync it but it is coming up each time. I had previously had another iPod with this same iTunes account, but it was lost. I bought this new one about 7 months ago and I have had no problem syncing until now. I also had to get a new hard drive for my computer, but that was about a year ago and I illegally saved the music files from my itunes to my new hard drive so I could have all the old music from my ipod on the new one. Is there any way I can get my music back onto my iPod or do I really have to set my itunes back to factory settings and erase all my media?

I've got a brand new iPod Video 60Gb and i have had this message since the first time i synced it. I think i restored the iPod about 10 times but it's always crashing when i unlupg it. It try to listen to something, the musics are on the iPod but they aren't listed in playlists or under artists or songs.
Then i plug it to iTunes and i got the message: iTunes cannot read the content.
I've bought a Belkin card just for it, the one recommended for iPod USB 2.0. Doesn't change anything. I've tried different USB ports, again, nothing new.
I was just going to try using USB 1.0 but it's sooooooooooooo slow that it will take me like 12 hours to sync the iPod!
I don't know what to do now, as i can't find if it's a computer problem or an iPod problem...

ALV Control and Classical ALV

Hi all,
Please let me know the advantages and disadvantages of ALV control over Classical ALV.
Thanks & regards,
Naresh.

ALV LIST Can be coded using only FMs
ALV control Can be coded using FMs and object oriented concepts
ALV LIST Can be displayed hieraicharlly
ALV GRID cannot be displayed hierarichally
Alv grid (using oo concept) requires
designing the screen layout .
Hence, in one screen, we can show more
then one alv grid
(we cannot show more than
one alv list on one screen)
ALV LIST is Display Only.
Whereas
ALV Grid Can Be made EDITABLE for entry purpose.

Search Help in Classical ALV

Hi All,
I have a small problem. Can anybody tell me how can i add a search help to a specific column in my classical ALV?
Regards,
Prakash Pandey

Hi Prakash,
In the Field Catalog there are two fields which are used to get the Search Help of any of the Column in ALV. Those are : REF_FIELDNAME and REF_TABNAME.
For example,
ls_fieldcat-fieldname = 'VBELN'.
ls_fieldcat-fix_column = 'X'.
ls_fieldcat-key = 'X'.
ls_fieldcat-outputlen = '10'.
ls_fieldcat-seltext_m = 'Sales Document'.
ls_fieldcat-edit = 'X'.
ls_fieldcat-ref_fieldname = 'VBELN'.
ls_fieldcat-ref_tabname = 'VBAP'.
append ls_fieldcat to p_fieldcat.
clear ls_fieldcat.
The above code will show the F4 for the column VBELN in the ALV.

Classic & ALV

Hi Friends,
I'm doing a comparison between ALV and classic report and I am trying to find differences. So far, I have gathered information regarding their
1) Interactivity (sorting etc. Classic needs more coding in this sense)
2) Capabilities (ability to export to other file format)
Does anyone know of any other major/important differences? It does not have to be too technical. Thanks in advance
Regards,
r3venant

r3venant,
Check
what are ALV reports? how they are different from normal reports?;&#57089;
ALV is nothing but "application list viewer.
An ALV displays the output directly in the form of a grid or a list.
ie,in a tabular format with the required field names as headings.
while in a normal report,user has to design and format his output in a list or table fashion,which is a tedious process.
it is to overcome the user designing the output in list,SAP has given ALV,thro which one can deirectly get a tabulated list output.
type-pool:slis is basically declared to call the respective function module for the ALV display.
its mandatory that type-pool:slis is declared.
Imagine you have to write a report that lists out customer addresses. You will write code to get the input from the user via selection screen and then read the data based on the seletion from the database into an internal table(or a set of internal tables). Now once you have the data you will need to output this. In normal list reports, you will have to use 'WRITE' statements to format the output into columns and rows. Now suppose user wants some interactivity in it. Then you will have to provide some buttons and/or menu options through custom pf-status and then write logic for reacting to the user actions. After writing many such reportsm, you will feel like some of this can generalized and reused in every report.
That is exactly what ALV does. It takes out most of repeated sections of the code from out of you and provides you with excellent outputting functionality. It provides many standard functions like 'print', 'sort', 'filter', 'sum' etc by default. Imagine writing code yourself for all these if you were writing normal list program. One more major difference is the editing feature. If you were write a program that gives the user with editing features, then you will have to write a lot of logic. But with ALV, all the features like adding a row, deleting a row, copying a row, editing some fields of a row etc come by default.
Likewise, interactivity has become quite easy to implement. Like double clicking on a customer number, if the user wants to go to display customer transaction, it is very easy using ALV.
As pointed out here by others, go through the documentation of ALV and go through some of those demo programs and you will know the difference. ALV takes out a lot of burden of coding everything away from you and lets you worry about the business functionality that your report provides, rather than formatting the output or providing interactivity to the output.

IPad, Acrobat Reader, Content (text and pictures) no longer showing, just blank pages

Hi,
I have a user who successfully opened a .pdf attachment from outlook mail and then opened it in Acrobat Reader on the iPad and then edited it and moved it to a created folder.
Everything was working fine and the user highlighted text in the .pdf document too.
What then happened is when the user subsequently opened the file, the highlights were shown but not the content (text and pictures).
I checked they had the latest version via the apps store updates and noted there had recently been an update which had been applied.
I did check also in the diagnostics to see if there were any acrobat files, but there were none, I also turned on 'send diagnostics' in case this this will help in the future.
I rebooted the iPad by pressing and holding the power and home buttons until the apple logo appeared.
Checked again to see if I could view the .pdf content (it's around 8.5 MB file with 32 pages), still nothing showing apart from the yellow highlights that the user had done.
From within Acrobat Reader on the iPad I chose to open the file in iBooks to see if I could read it there. I could successfully open the file in iBooks and the front page thumbnail was showing (I did note that in Acrobat reader the thumbnail was white).
I found the email with attachment and opened it again in Acrobat Reader and it opens correctly, suggesting somehow the previous copy had become damaged? I have now saved this good copy over the top of the existing bad copy and all is OK except that the user has lost the highlights previously made.
Can you give me some idea of how this file has become broken in Acrobat Reader on the iPad and how I can avoid it happening again.
Many Thanks.

Thanks for replying.
This is the first time it has happened, the user has several folders containing files (on their iPad), (some .pdf's with additional highlights) these files are typically company agm board packs so contain pages of text and photo's too.
I put it down the fact that when I checked the app store for updates there had recently been an update and the user had not rebooted their iPad for some time, hence some of the underlying adobe reader files were perhaps between versions.
I don't know how you handle files when performing an update, do you close the app, flush files from memory and do a clean update?
I can confirm that the .pdf file had not been sent as an email attachment after having added the highlights.
Because the acrobat document contains so many pictures (32 pages and 8.5MB) when scrolling through it takes several seconds for some pages to appear, and others with text and pictures quite a while for the text to become sharp, I presume this is because the Acrobat Reader cannot open the 8.5MB file in one go and has to keep swapping it out of memory. Having reached the end if I scroll back to the beginning it takes 10's of seconds before the first page re-appears, otherwise it's just a white page. Interestingly in iBooks the pages appear almost immediately when viewing.
The iPad in question is model MD368B/A, 64GB, Software Version 7.1.1 (11D201) and has 28GB Memory available. Usage tells me Adobe Reader is taking 328MB and is version 11.3.1
I have just finally browsed back to recent documents, opened 2 or 3 other documents and then this one again (from recent) and it is now broken, just shows white pages (and on the thumbnail too) with my test highlights. so I can now apparently reproduce it.
Hope this all helps you re-produce

Query regarding file content conversion using file adapter

Hi All
I have a question regarding file content conversion in file adapter.
I have a file coming in the following format.
AA,111,222,333
BB,444,555,666
CC,777,888,999
My incoming message structure has a hierarchy. The CC record is a structure part of BB record. BB record is a structure part of AA record. It is like this:
AA,111,222,333
<<BB,444,555,666>>
<<<<CC,777,888,999>>>>
After file content conversion, in the resulted xml, i am getting a flat hierarchy instead of nested hierarchy.
Is it possible to get a nested hierarchy as a result of file content conversion?
Please let me know
Thanks
Chandra

Hi Udo
According to your suggestion, I am trying to use mapping.
I am getting a flat file and i am reading it.
This is my source structure:
AA,11,22,33
BB,44,55,66
CC,77,88,99
This is my required targer structure:
AA,11,22,33
<<BB,44,55,66>>
<<<<CC,77,88,99>>>>
To explain this, BB record can have multiple records of CC records.
AA records can have multiple records of BB record.
I am using removecontext node function.
CC (Source) (removecontext)-> CC (target structure)
But here, when i rightclick on source CC field in the mapping editor, i cannot see any other context except root node. So, how can i proceed here??
Many Thanks
Chandra

How to read contents of files that do not fall under public security group?

Hi,
I need to read the contents of a WCM based xml file that does not fall under public security.
The process is like this:
First the user makes chnages to the content.
The workflow will be triggred based on the security group metadata that is associated with the content.
Once the content is finally approved our workflow calls a custom idoc script.
First we tried directly reading the xml contents from the idoc script which was still in the context of workflow. But since content item is still in workflow I was not able to read the changes. So I created a separate content publisher thread and read the DOC_INFO and checked for the dStatus value. If the value is RELEASED then I reading contents by calling ssIncludeXml idoc script.
This was working fine for public content. But now the requirement is that all content cannot be public. Content authors should not be able to edit the content that does not belong to their group, So we created security groups (and roles) and are associating that groups to the relavent content.
Beacuse of this change I am not not able to read the non public content. The call to DOC_INFO_BY_NAME service, which gives all the content files' metadata, is expecting the user to be logged in to give the details.
I tried calling the CHECKIN service with sysadmin and captured the cookies returned by that service and use cookies for the DOC_INFO_BY_NAME service call. But the service call was faling. It is throing the 401 forbidden error with the message that user needs to be logged in to get the details.
How to address this problem. Someone please help.
Note: I also tried using ridc for this. I was able to get it working but since it is executing in the context of server ridc api is changing server's environment properties like HTTP_HOST, HTTP_CGIPATHROOT etc. It also seemed like system was becoming non functional after using ridc. When I called check-in the system metadata values like security group are no more loading. Not sure if ridc is the culprit here but worried that it might be causing this issue.
Regards,
Pratap

Sorry, I posted too much details while posting this question. I was saying "not able to read *non* public content".
Anyway, I was able to resolve the issue. I was able to authenticate with sysadmin credentials in the request to service using basic authentication and was able to read doc info with that credential.
But I realized there is more than option for reading secure content.
- I could set user name as sysadmin in the m_environment (if I am in the context of a service) and the call the DOC_INFO_BY_NAME service.
- I can post an HTTP request to DOC_INFO_BY_NAME service with sysadmin credentials and do basic authorization via the connection. (This is what i have done successfully as of now )
- I could add guest role to all security groups with R (read) privileges.
I will look into all options and implement the one which is more apt.

Pratap

Regarding displaying role description in alv

Hi All,
Here i got struck up with an issue. I want to display role name and its description. But my problem is description is having more than a single line. I need to concatenate all the lines, But I don't know what to do here exactly. I need to display the output in LAV format. And one more thing the description length is more than 255 characters also in that case how to handle.
Please suggest me a solution for this.

EVENTS in Classical ALV

Hi,
I want to know the Purpose of using the below Events in Classical ALV (if possible with example).
1. CALLER_EXIT
2. REPREP_SEL_MODIFY
3. top_of_coverpage
4. END_OF_COVERPAGE
5. TOP_OF_FOREIGN_PAGE
6. END_OF_FOREIGN_PAGE
7.SUBTOTAL_TEXT
Thanks in Advance,
Sumi

The I_EVENTS table returns with the following possible constants:
1.     Slis_ev_item_data_expand TYPE slis_formname VALUE 'ITEM_DATA_EXPAND'.
Only relevant for hierarchical-sequential lists using the layout parameter IS_LAYOUT-EXPAND_FIELDNAME of the structure IS_LAYOUT. Exit for passing item entries (ITEM table) for a header record that was expanded interactively by the user.
2.     Slis_ev_reprep_sel_modify TYPE slis_formname VALUE 'REPREP_SEL_MODIFY'.
RS_SELFIELD-TABINDEX contains the header table index for which the item entries are to       be put in the global item output table (T_OUTTAB_SLAVE). The Callback is only called if ALV has no items for a header that is to be expanded.
RFLG_ALL is passed with 'X' if the user shows all items. The application must ensure that    entries are not repeated in the item table.
    RS_SELFIELD is initial in this case.
3.     Slis_ev_caller_exit_at_start TYPE slis_formname VALUE 'CALLER_EXIT'.
Is called at the beginning of the function module to make special settings. It is not usually used.
4.     Slis_ev_user_command TYPE slis_formname VALUE 'USER_COMMAND'.
As this is a frequently-used Callback event, the form routine can also be passed        directly in the interface by passing the user command in the IMPORTING parameter           I_CALLBACK_USER_COMMAND.
5.     Slis_ev_top_of_page TYPE slis_formname VALUE 'TOP_OF_PAGE'.
   Equivalent to the list processing TOP-OF-PAGE event.
6.     Slis_ev_top_of_coverpage TYPE slis_formname VALUE 'TOP_OF_COVERPAGE'.
The selection information and list status are output together (if they exist) on a separate page by default
7.     Slis_ev_end_of_coverpage TYPE slis_formname VALUE 'END_OF_COVERPAGE'.
Analogously to TOP_OF_COVERPAGE the user can add other information
to the information output by ALV (selection information, list status) at this event.
8.     Slis_ev_foreign_top_of_page TYPE slis_formname VALUE FOREIGN_TOP_OF_PAGE'.
The Top-of-page event is always processed in ALV and is only passed to the caller via the Callback mechanism. This is still the case if the caller, e.g. by a user action, processes a branch list which was not formatted by ALV (e.g. a popup with additional information about the list record selected and displayed by ALV).
In this case, top-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event top-of-page still occurs in ALV. When ALV notices a top-of-page which was not caused by an ALV output, the form routine in FOREIGN_TOP_OF_PAGE is called.
9.     Slis_ev_foreign_end_of_page TYPE slis_formname VALUE 'FOREIGN_END_OF_PAGE'.
The event end-of-page is always processed in ALV and only passed to the caller via callback. This is still the case, e.g. when the caller processes a details list which was not formatted by ALV (e.g. a popup with further information about selected list records which were displayed by ALV).
In this case, end-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event end-of-page still occurs in ALV. When ALV notices an end-of-page that was not caused by an ALV output, the form routine in FOREIGN_END_OF_PAGE is called.
10.     Slis_ev_pf_status_set TYPE slis_formname VALUE 'PF_STATUS_SET'.
If a user list status is to be set, it must be done in the form routine assigned to this event. The ALV function codes, which must not be active, are in the Parameter RT_EXTAB. This table must be passed with the SET PF-STATUS command (with inactive user function codes as well, if necessary).
The STANDARD status of the function group SALV should be used as a          template for a user-specific status. As this is a frequently used Callback event, its form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_PF_STATUS_SET.
11.     Slis_ev_list_modify TYPE slis_formname VALUE 'LIST_MODIFY'.
LIST_MODIFY USING R_TABNAME TYPE SLIS_TABNAME
                                         R_INDEX LIKE SY-TABIX
                                         R_INDEX_ITEM LIKE SY-TABIX
                                         R_INDEX_SUM LIKE SY-TABIX.
12.     Slis_ev_top_of_list TYPE slis_formname VALUE 'TOP_OF_LIST'.
Information output at the start of the list
13.     Slis_ev_end_of_page TYPE slis_formname VALUE 'END_OF_PAGE'.
Information output at the end of a page. This is only called for printing.
14.     Slis_ev_end_of_list TYPE slis_formname VALUE 'END_OF_LIST'.
Information output at the end of the list
15.     Slis_ev_after_line_output TYPE slis_formname VALUE 'AFTER_LINE_OUTPUT'.
Output information after each output line. Should only be used in justified cases because it costs a lot of performance.
16.     Slis_ev_before_line_output TYPE slis_formname VALUE   'BEFORE_LINE_OUTPUT'.
Output information before each output line. Should only be used in justified cases because it costs a lot of performance.
17.     Slis_ev_subtotal_text TYPE slis_formname VALUE 'SUBTOTAL_TEXT'.
This event table (I_EVENTS) is now checked with the desired constants. If the desired constant is found, then the corresponding field for the FORM NAME is populated with the name of the routine containing the corresponding event.

Hello,
ODI is an ELT product and not a Reporting one.
To work correctly with this tool you need good knowledge about Databases ans SQL.
About the market I can't answer you, I know that a new ODI major release will go out in 2009 and i think that all will depend on, this release is announced as totally different of the last one.
Essbase is one of the technology which is managed by the product, I don't really see the need for planning knowledge...
In ODI you can work with different DB, coding in SQl or directly in OS language, Java or Jython which are the only accepted language (if i'm right).
Hope to be helpfull,

Read contents of file

hello,
i want to read the contents of an image file without really opening it. i know this can be achieved by reading the header and footer of the file. this header and footer contain details regarding the contents of the image file. with this i can know the pixel arrangement of the image. how can i acieve this?
asrar

You could use a RandomAccessFile object if you know the size in bytes of the header and footer. For the header you would read the first X number of bytes where X is the length of the header. For the footer you'd use the "seek" method to seek to the L - Y point in the file where L is the length of the file obtained using File.length() and Y is the length of the footer. Then read the remainder of the file.
You could also use the new Java NIO package to read the various parts of the image file directly into byte buffers. You'd create two ByteBuffers big enough to hold the header and footer and a third that contains the rest of the file. Check out the java.nio.channels.FileChannel class.
But the guy who posted before is right in that you have to open the file if the header and footer are part of the file.

Save contents of editable alv into dbtable

Hi All,
I have an alv output with editable fields. This output has the contents some from an itab and some are hardcoded in the program. Now I have edited the contents in the alv o/p.
Now I want to save the contents of the alv o/p fully into the dbtable.
Please suggest how to do this.

Hi,
STEP :1.
In the PBO of the Screen in Which you are designed your container for output - SET the PF-STATUS.
Example : SET PF-STATUS '1500'.
In this PF Status you activate the SAVE Button.
I think for SAVE Button the sy-ucomm = 'SPOS'.
STEP 2:
In the PAI of the Screen in Which you are designed your container for output.
Write the below code.
IF SY-UCOMM = 'SPOS'.
    CALL METHOD G_GRID->CHECK_CHANGED_DATA
      IMPORTING
        E_VALID = L_VALID.
    IF L_VALID EQ 'X'.
      CALL METHOD G_GRID->GET_SELECTED_ROWS
        IMPORTING
          ET_ROW_NO = LT_ROW_NO[].
    ENDIF.
At this Point your output table will have the modified values.
Now you can proceed it to update the database table.
ENDIF.

Amir
