ALV oops - Prioritizing the events and customizing ADD icon in toolbar

Hi Experts,
Please help me on how to achieve the following functionalities in ALV:
1. I have the events data_change_finished and user_command.Is it possible to trigger the event user_command first when both events are simultaneously called?
2. I have an alv grid which initially has 3 rows of which in each row 4 cells are editable and 3 are non-editable.Now,when the user clicks on the toolbar to append a new row,I need to have only one cell as editable. For me it appends the new row which is the replica of the exiting row
Kindly help me to resolve this issue.
Thanks and Regards,
Archna Raja

Hi Archna,
Two events can't be invoked simultaneously. So I am not quite able to visualize your scenario.
For disabling individual cells in an ALV you can set cell properties for each cell as Disabled or Enabled.
When a new line is added you can write the specific code to disable the additional two cells.
Write in if you need more.

ALV OOP- Catching the event when the user clicks a cell

Hi Experts,
i have 2 alvs to display using custom containers, now the problem is that i need to make some lines uneditable and some lines editable. On making this i find that ALV does not offer this functionality of selective editable rows, right? I offered a workaround by just popping an error message if a user clicks a row which suppose to be disabled/uneditable. My problem is that how can i catch the single click event in ALV using OOP?
Thanks to replies and points will be given...

hi,
hope this helps.
creating Editable Cells in ALV
Making a column editable in ALV:
IT_FIELDCAT is an internal table which has the structure of the data to be displayed. Each row in this internal table creates a column in ALV. The fieldcat structure has an optional field u2018EDITu2019 which is not required to be passed all the time. By default the column is non-editable. If the value of the field EDIT is u2018Xu2019, that column becomes editable in the display.
Example:
wa_fieldcat-fieldname = 'CHECK'.
wa_fieldcat-edit      = 'X'.
wa_fieldcat-coltext   = 'Delete'.
APPEND wa_fieldcat TO it_fieldcat.
CLEAR wa_fieldcat.
The column DELETE in the ALV display is editable. The corresponding output internal table field name is CHECK.
Making individual cells editable or non-editable:
1.     Include an internal table of type lvc_t_styl in the output internal table (as a field) of the ALV. This inner table is like other output fields of the internal table.
Example:
TYPES: BEGIN OF tt_project,
            check TYPE c,
            status(132) TYPE c,
            it_styletab TYPE lvc_t_styl.
TYPES: END OF tt_project.
2.     This inner internal table controls the style of each cell in the row of the output internal table.
3.     Same like other fields of the output internal table, this style table (inner internal table) should be filled for each row of the table.
4.     The structure of the output internal table.
CHECK     STATUS     IT_STYLETAB
X     ABC     Fieldname     Style
CHECK     Non-editable(MC_STYLE_DISABLED)
STATUS     editable(MC_STYLE_ENABLED)
     CDF     Fieldname     Style
     Non-editable(MC_STYLE_DISABLED)
      wa_stylerow-fieldname = u2018CHECKu2019. -
> Optional
      wa_stylerow-style = cl_gui_alv_grid=>mc_style_disabled. (Non-editable)
      or
      wa_stylerow-style = cl_gui_alv_grid=>mc_style_enabled. (Editable)
      Append wa_stylerow to wa_project-it_styletab.
     Wa_stylerow is a work area for IT_STYLETAB.
       Wa_project is work area for output internal table.
5.     Refresh the inner internal table for each row in outer internal table.
6.     If the fieldname is not provided for the style internal table, the entire row becomes editable or non-editable.
7.     This provides the ability to enable input for a cell dynamically.
8.     The layout of the ALV Grid should also be changed in order to achieve this. The layout has a parameter, u2018STYLENAMEu2019. The name of the style internal table should be given as the value for this field. The layout should be passed in SET_TABLE_FOR_FIRST_DISPLAY.
     Example:
     wa_layout-stylefname = 'IT_STYLETAB'.
reward if useful.

How to delete all the events and create new events from scratch?

I have all my photos separated into albums and I would like these albums to be considered events in iPhoto. The problem is that there are already lots of events in my iPhoto library that are not "real" events. It just so happens they were uploaded at a certain time and during one of my upgrades of iPhoto all these different uploads became different events. Of course, there are some albums I would like to become a single event as well...but I am not sure how to strip all of my photos of events and then add the photos to new events?

Select all the pics in an Album and Flag them.
Then go Events Menu -> Create Event from Flagged Photos
A new Event is created that moves the pics from their existing Event
Unflag the Photos then move to the next album. Repeat.
Regards
TD

Profit Center population in the Vendor and Customer Line items

hello
our client is asking for getting profit center in the vendor and customer line items where in the view FBL5n and fbl1n we are not getting the profit center populated - in the new gl i understand that there is a standard report based on the gl account.
but our business is not satisfied with the report and expecting report at profit center level.
Can any one suggest any way of doing this.
regards,
Vijay

Dear Vijay,
Let me provide you my view of solutioning for this. This is an enahcement that needs to be done
1. You can get the profit center from the given vendor and customer line item at the time of posting, using an enahcement you will be able to capture it.
2. Existing the profit center field is not populated in the BSIK,BSAK,BSID and BSAD tables
3. Hence, in the same enhancement once you capture the profit center , you can write the code that profit center is updated in these tables also.
4. This will help you to do the vendor line item wise selection in the FBL1N, FBL5N profit center wise.
Constraints of this solution:
The only constraint remains where in the for a given document if there are multiple profit center, then the system will do the splitting profit center wise for a vendor line item, which will not populate the profit center in those tables as there is only one field available in the bsid etc.. tables.
This basically would be the one the soltuion where in as seeen from the end user ther eis no change in the front end interface , the way they are doing always they can do.
You need to also take care the % of document splitting means cross profit center postings /cross document splitting charactericstics postings and the volume involved in this. so that you can suggest this to your client.

Bharathi.

How to stop the spinning ball/pizza that is stalling repairs to project on imovie 09? on macosx10.5.8 using iomega and superspeed ext h.d. as storage for the events and projects archive of a wedding video that has had audio sync problems on all share form

How to stop the spinning ball/pizza that is stalling repairs to project on imovie 09? on macosx10.5.8 using iomega and superspeed ext h.d. as storage for the events and projects archive of a wedding video that has had audio sync problems on all share formats (iDVD, mp4, and last of all iTunes). The project label now carries signal with yellow triangled exclamation “i tunes out of date”.
To solve the sync problem I’m following advice and detaching sound from all of the 100 or so short clips. This operation has been stalled by the spinning ball. Shut down restart has not helped.
The Project is mounted from Iomega and superspeed ext hd connected to imovie09 on macosx 10.5.8.
What to do to resume repairs to the audio sync problem and so successfully share for youtube upload?

An event in one of my libraries no longer has the event icon next to it's name just the name only. I can't view the clips in the event or import new clips. I've tried deleting the event and nothing.

an event in one of my libraries no longer has the event icon next to it's name in the browser just the name only. I can't view the clips in the event or import new clips. I've tried deleting the event and nothing. After control clicking the event it shows all the media that has been previously imported. But it does not allow anything to be done to the event including deleting. This showed up at the beginning of a normal import session. This is fortunately the back-up evant.

Did you perhaps mess with the contents of the library in the Finder?

I upgraded my iPod Touch 4th Gen yesterday. Now it won't play music, which is the main thing I use it for. Over 11,000 songs [it's a 64GB model] -- will I actually have to restore the device and re-add all that music?

I upgraded my iPod Touch 4th Gen yesterday. Now it won't play music, which is the main thing I use it for. Over 11,000 songs [it's a 64GB model] -- will I actually have to restore the device and re-add all that music?
[Music files are still there, and I can play them on my computer directly from the iPod [just one track at a time] but not in the usual way, through headphones.]
On the Summary page of iTunes for the iPod, it shows 50-plus gigabytes of "Other" content and no music, which was not previously the case. I assume this is related to the problem.
I can bring up individual tracks on the iPod and see cover art, but cannot play the music.

iCloud is free, iTunes match is $25 a year.
I had the same problem and when I went to Settings I had 0 songs, even though they were obviously still there since I only had 15GB free on my 64GB device.
I decided to do a complete reset/restore of my 4th gen iPod Touch, Bad move! I've been messing with it for hours, and it simply won't restore--it keeps hanging on a black screen with an Apple logo and a progress bar at about 10%, sometimes it goes completely blank and tries again, with the same result. (I've posted my question/plea for help here: https://discussions.apple.com/message/19735862 )
I'm ready to bang my head against the wall! I can put the device in recovery mode, connect to iTunes on my computer, and get it back to the setup screen, but when I go through the process again and try to do an iCloud backup I get the same reset/restore loop.
I could start from scratch, but I really, really, really don't want to go through all of my hundreds of apps, reinstall them one by one, etc. etc. etc.
I thought that once I started using iCloud, I didn't need to sync with iTunes anymore--guess I was wrong.

When I connect my iPod touch to my computer, I have a list of Events on my iTunes/iPod/Photos. I want to erase these Events. However, the photos are NOT on my MacBook Air. When I check one of the Events and then hit Apply, the photos appear on my iPod.

And one last thing: When I connect the iPod and open iPhoto, iPhoto tries to load New Photos (I think), but nothing happens. Any ideas?

Resolved.

How to use the eventing and databag with a WAS 6.20 ?
Is what there is a good guide for these services?
Thank's

In the raise event you can pass the value
like below.
<SCRIPT>
function raiseEvt(value1){
if(window.document.domain == window.location.hostname){
if ( document.domain.indexOf(".") > 0 ) document.domain = document.domain.substr(document.domain.indexOf(".")+1);
   EPCMPROXY.raiseEvent( "urn:com.sap:BWEvents","BWiViewevent", value1, null );
// alert('tree domain'+document.domain);
</SCRIPT>
and in the
subscribe event you can get the values like below.
<script language="javascript">
if(window.document.domain == window.location.hostname){
document.domain = document.domain.substring(document.domain.indexOf('.')+1);
    EPCMPROXY.subscribeEvent("urn:com.sap:BWEvents","BWiViewevent", window, "myreceiveEvent");
function myreceiveEvent( eventObj ) {
      document.forms[0].gp_hidden.value = eventObj.dataObject;
</script>

That happens when iPhoto breaks the file path/link to the original image file. Try the following:
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
2 - Run Option #4, Rebuild Database, followed by Option #1 if needed.
