CL_GUI_FRONTEND_SERVICES error

Former Member — Wed, 06 Jan 2016 10:00:42 GMT

Hi Experts,

Scenario:

i have provided interface to user where all pdf files from desktop directory are listed in ALV.

clicking on any desired file that file is opened in SAP container.

then user clicks on move file button which moves that file from one desktop directory to another as maintained.

i am using following methods in sequence to check file existence, then copy to destination and then delete from source.

FILE_EXIST

FILE_COPY

FILE_DELETE

I am facing issues with following methods of class CL_GUI_FRONTEND_SERVICES

FILE_COPY

FILE_DELETE

Only in fewer cases ( 1 or 2 out of 100 files ), file is not moved as either of above mentioned methods give exception as "Access Denied".

Not able to find exact reason for above behavior.

Kindly guide through this

Thanks

Hi,

FILE_COPY

ACCESS_DENIED thrown If either the source file cannot be accessed for reading or the new file cannot be created in the specified directory.

FILE_DELETE

ACCESS_DENIED thrown if the account with which the user is logged on to the PC has not the permissions required to delete the file.

thanks!!

Thanks for your reply

But user has full authorization and permission to read write copy and delete file.

because all files are moved successfully except 1 or 2 files only.

Has the file copy completed before you attempt to delete the file ?

yes file is copied completely.

in such cases where delete is failed, i have two copies of that file one in source and second in destination.

I think you need to check the variable which holds the file name.

These methods have importing parameter as STRING

so i am using the same for variable which holds file path.

any other aspect which can be checked for that variable.

it's not about length it's about the variable holds the file name or not where it's giving exception of ACCESS DENIED while deleting.

Hello friends,

Issue is resolved, so closing this thread.

Few files which were facing error for FILE_COPY and FILE_DELETE with "Access Denied" exception.

All those files have "Read-Only" ticked in their properties.

So, as read-only property is removed files are moving correctly.

Thanks to all for your time and suggestions.
