Delete attachment

Hi all,
I am newbie in BPM. I am confuse about deleting one of attachment that i store in instance BPM attachment (this.attachments).
Example:
I create attachment twice..
- Attachment.create(contents :content1, name :..., description :'desk1', remarks :...);
- Attachment.create(contents :content2, name :..., description :'desk2', remarks :...);
How to delete the first attachment?
I can identify the first attachment use looping.But i dont know to delete this.
Here is the snippet code:
for(Attachment attach :this.attachments){
if(attach.description=='desk1'){
//do things here
Edited by: user10903377 on Dec 6, 2009 7:15 PM

The answer for your question depends on what that method create is doing...
To delete an attachment, all you have to do is stop referencing it.
perhaps this source can clarify what I'm saying:
//Create the attachments
attachments as Attachment[]
for i in 0..2 do
insert attachments using int = length(attachments), value= Attachment()
end
//Delete the second attachment
result as Any = delete centros[1]
I hope it helps...

Outlook delete attachment files if use POP3

Hi every body,
I have a problem with outlook. I send a mail with attachment using java mail api. Anyone get the mail correctly (gmail, outlook, outlook express or thunderbird) via SMTP. But if outlook try to get the mail via POP3, it deletes attachment and show only other part of mail. Other clients dont do it include outlook express. I dont have any idea about this situation. Can any body help me?
My mail code is here:
Properties props = new Properties();
props.put("mail.smtp.host", server);
props.put("mail.smtp.port", String.valueOf(port));

Yes i was wrong. I use SMTP to sent mail, and POP3 to read it. Mail is shown with attachment in gmail but it is shown only body in outlook. If i open socket and sent mail via socket it is worked.
Now i search using this method with attachment. Does any body know that?

Delete Attachment in activity/interaction record ICWEB ???

Hi Laxman,
      The code you have mentioned is fine.
     But the bug might exist in UI or BOL layer. Just to be sure that save is successful, I always use the below code. You may try the same.
IF lv_transaction->check_save_needed( ) EQ abap_true.
    IF lv_transaction->save( ) = abap_true.

We are using CRM 5.0
Thanks,

New Mail Message Won't Let Me Delete Attachment

MacBook Pro (Retina, 15-inch, Mid 2014)
10.10.2 (14C109)
2.8 GHz Intel Core i7
16 GB 1600 MHz DDR3
500 GB SSD
NVIDIA GeForce GT 750M 2048 MB
Now some fun with emails.
I composed a lengthy, carefully thought out, email to my CPA. Then, without thinking, I added an PDF document as an attachment right in the middle of the text. Can happen to anyone.
I spent the next 20 minutes looking for a delete, CMD X, edit delete, or someway to remove the attachment. No luck, CMD Z did remove the CC: entry I just added, but not the attachment. Can't drag it.
So I spent another 10 minutes manipulating the text, ever so carefully, around the attachment, so the attachment would appear at the bottom on the email.
So tell me. Someone actually designed it to work this way? Or maybe design is too harsh of a word. It is a **** of a lot of work for something that should be so simple.

Normally, you delete objects like that in mail by either positioning the cursor just after the attachment and pressing delete. Or by clicking once on it and pressing delete.

I have the same problem. How can I remove the link? After I called the mentioned function module, the attachment was removed (content) but in the UWL the file name is still there:

How to delete attachment to reduce size of message

I recently moved over from Eudora to Mail.app
In Eudora, all attachments were put in an attachments folder, so the size of the actual message in the mailbox was small.
In Mail.app, it seems that the attachments stay as part of the message, even if I save them to another location. If I try to delete the attachment (a jpg for example) it deletes the entire message.
Is there a way to keep the message, but delete the attachment, so that my mailbox size stays small?
thank you...

LOL!
Full marks for spotting my deliberate error!
Ta for the star!

How to recover deleted attached mdf file from sql server management studio

Hi everyone
I've faced very bad problem
I had a mdf file that created in visual studio, and then I had attached this file to sql server management studio and after that, when I wanted to deattach
this file I had a big mistake; and deleted the mdf file; then now this file was deleted from my computer
I test several recovery tools but they can't find deleted mdf file; the volume of the mdf file was more than 2 GB.
Please help me if you can

Hello,
If you don't have a backup of the database, then it's not really possible to get it back. There are some "Undelete" Tools available for Windows, but when even only one page was overwritten on disk, then it's not possible to recover it.

Delete Attachment - GOS

Hi,
I am deleting a GOS attachment using following code.
data: i_borident type borident,
       i_attsrv    type ref to cl_gos_document_service.
i_objectd-objtype = 'YATTA'.
i_objectd-logsys = 'BO'.
i_objectd-objkey = inumber.
select * from srgbtbrel                " Get GOS Link
           into table i_srgbtbrel
           where instid_a eq i_objectd-objkey
             and typeid_a eq i_objectd-objtype
             and catid_a eq i_objectd-logsys
             and reltype eq 'ATTA'.
if sy-subrc eq 0.
    create object i_attsrv.
    loop at i_srgbtbrel.
     i_borident-objkey = i_srgbtbrel-instid_b.
     call method i_attsrv->delete_attachment
       exporting
*         is_object     = i_objectd
         ip_attachment = i_borident-objkey.
     commit work.
    endloop.
endif.
I am getting proper binary key from table SRGBTBREL and passing to method DELETE_ATTACHMENT , and getting sy-subrc eq 0, then also attachment are showing in the document. But if you are going thru service object delete it has been deleting the attachment perfectly. What is the error in the code?
Thanks

Hi.
You are missing SO_OBJECT_DELETE_IN_VB:
    data ls_folder_id type soodk.
    data ls_object_id type soodk.
    loop at i_srgbtbrel.
      i_borident-objkey = i_srgbtbrel-instid_b.
      call method i_attsrv->delete_attachment
        exporting
*         is_object     = i_objectd
         ip_attachment = i_borident-objkey.
      ls_folder_id = i_borident-objkey(17).
      ls_object_id = i_borident-objkey+17(17).
      call function 'SO_OBJECT_DELETE_IN_VB'
         in update task
         exporting
           folder_id = ls_folder_id
           object_id = ls_object_id.
    endloop.
    commit work and wait.
At the end of cl_gos_document_service->delete_attachment, there is the line:
call function 'GOS_ADD_KEY' exporting ip_objkey = ip_attachment.
This function adds the deleted item to table gt_obj_to_delete.
Later, the standard makes the call to SO_OBJECT_DELETE_IN_VB at include LSGOSITSF01, form DELETE_OBJECTS using gt_obj_to_delete.
Thanks.

Composing a new email message, can't delete attachment

While composing an email message, I attached a file. Realizing I attached the wrong file, I couldn't find any way to delete it, and attach the correct file instead. I had to create a brand new message in order to attach the correct file.

I played around with it some more, and have discovered what is really going on. After you add one or more attachments to a composing email, there are two different ways to select an attachement. One way is to click on the icon (the cursor will show as an arrow pointer). You can then do edit - cut, and remove the attachement. Another way is to click on the name of the file below the icon (the cursor will show as a link pointer). This will open the file and move focus to the program that the file is opened under (for instance MS Word). That was what was confusing me. However, if you move focus back to Mail (by clicking on the email you are composing) the attachement will be selected, and you can either use the delete key, or use edit/cut to delete it.

Question about SAP_WAPI_ATTACHMENT_DELETE and deleting attachment in WF

I find SAP_WAPI_ATTACHMENT_DELETE with import parameter of WI_ID just delete the attachment of the entered workitem. If the WF process continues to the next step and generates a new workitem, the workitem still has the attachment.
Other question: What is the system of storing attachment in WF? Are they stored in the container ? Or What is saved in the container element is only a reference? Can I delete a attachment globally? Is there any statement to delete the attachment?

Hi Sun,
Please check whether you have inserted a attachment objects to the father work item id or to the current work item id.
and after deleting the attachments please check the log for attachments.

Disable 'Delete' button for posted invoices in GOS Attachment List

Hi,
when i open the attachement list of a generic object i see the attached files. In this dialog i want to disable the "Delete" ( attachment) button for Posted invoices ( In MIR4 tcode -> If the invoice is already posted it should not allow to delete the attachment )
I read oss notes and some ides of copying diverse classes but nothing really helps.
I found two badis
GOS_SRV_REQUEST
GOS_SRV_SELECT
but i dont know where we have to write our code .
I read so many posts related to attachments but all the places described about authoriztion object .
Can you please give some ideas to disable the delete button for posted invoices.

Hello,
For GOS there is no SAP Standard authorization concept. The only way to
manage GOS authorizations is implementing it via custom code as
described in SAP Note: 491271.
Please have a look at the SAP notes:
491271 Authorizations for generic object services
701609 Authorizations for services: Final classes
For the use of S_OC_ROLE: this object states if a user is an office
administrator he can create, modify or delete every document, even
those created by other users. If the user is not an office admin, the
user is still able to create his own attachments.
Regarding to the issue, there is an role object S_GUI for upload.
To match your inquiry, pleaes find the user's role and active the
object S_GUI.
Regards,
David

How to disable delete option or symbol in attachment control in infopath 2010

Any have any idea how to disable the delete option or symbol near the attached file using attachment control in infopath 2010.
I have created a custom list in sharepoint online 2013(Office 365) and customized it in Infopath forms 2010
i want tht user can attach the files using attachment control but not to allow to delete other attached files.
plzzzzzz help me out :( .

Hello,
As per my finding, you have to custom create event receiver to handle this situation. Use "ItemAttachmentDeleting" event to prevent user to delete attachment. Please refer below MSDN link to implement this:
