File Lock - How to lock and unlock a file ? Can we do that for an FTP File?

Hi All,
I like to retrieve a file from the FTP server using Apache Commons Net libraries.
for example if the file size is 20MB. When the file is in the progress of copying or transferring from the FTP server i need to lock the local file which is in our local directory so that no other process will use the same local file which is in the process of copying otherwise partially copied files will be used by another process.
the file should be locked when it was in the progress of copying from the server. I have an automatic process which will access file objects at certain time and try to process the files.
I like to know the simplest and easiest way to lock and unlock a file object locally which is trying to copy a file from the FTP server which is of huge size.
And also i like to know how to lock and unlock a file in general?
Thanks,
J.Kathir

we can set it read only only when it complete finishing the writing.
can we able to make the file as read-only while transferring data to file.
How to achieve it ? pls give me some sample code

Dave,
I will +1 Pixelan's products. They are great, simple, and have about the best support that I know of. When you explore, say Pixelan's SpiceMaster, dig deeply. Things appear rather mundane, on the surface, but there is so very much power lurking, just below the surface. I could almost imagine a 1000 page manual to cover every possible aspect of that program... Every time that I use it, I learn something new, and wonderful.
Good luck,

Does anyone know how to lock a specific application, such as e-mail in Ipad?

I have my company email in my Ipad and I want to lock it in order to prevent whoever uses my Ipad to login to my email. Does anyone know how to lock a specific application or it cannot be locked?

There is a somewhat clunky way to do it. First, go into your mail (Settings - Mail/Contacts/Calendars) and turn off (dont' disable) any accounts you don't want to be seen. Then go into Restrictions - Accounts and select "Don't Allow Changes." This will prevent anyone from turning the mail back on. When you're ready to turn it back on, go into Restrictions and either Disable Restrictions or go into Accounts and select Allow Changes.

How to capture workitem number

Hi Experts,
We have custom workflow for creating material master. The main workflow contains different sub workflows and tasks. The workflow has 4 levels approvals and it has been triggering from Z transaction using event.
We have the requirement for report to know the Overview of all material requests currently open; (at which specific step are they pending?), Daily Overview of all requests currently open for more than 24 hours at a specific department: including assigned user.
But this data we are not capturing in the Z-tables. We can get it from workflow standard tables like SWWWHEAD. For all these standard table required workitem id which is unique and will dynamically generates the number.
My question is how to capture workitem number. Is there any function modules/reports/process to get the workitem number specific to object type/object key?
Thanks in advance.
Cheers,

Hi ,
You can use the standard WAPI for getting the workitemids for specific material nos . But when you are going to develop report for multiple material nos then you need to call the SAP WAPI in side LOOP and END LOOP , which will affect the performance of the report .If the no of entries is less to be displayed in the report then you can use the SAP WAPI . Other wise you can try the below code for better performances -
Get all your material nos in one internal table say ITAB1 .
IF ITAB1 IS NOT INITIAL .
    SELECT   top_wi_id wi_rh_task instid FROM sww_wi2obj INTO TABLE
    itab2 FOR ALL ENTRIES IN ITAB1
      WHERE instid = ITAB1-instid
                  AND catid = 'BO'
                  AND typeid = 'BUS1001006'
                  AND wi_release = '700'
                  AND wi_reltype = '99'
                  AND removed = '   ' .
ENDIF .
You will get the workitemid of workflow specifc to all materials in the internal table ITAB2 - The field is - top_wi_id
Just try this out . Hope it may help you .
