Hi Welcome to SDN,

I don't think there is a FM for that.

hi,

Welcome...

I guess You have to know where is the file, so use the GUI_UPLOAD to upload it.

Welcome to SDN !!!!!

Take a look at the Class CL_GUI_FRONTEND_SERVICES.

Some of the methods are useful would be :

1. GET_SYSTEM_DIRECTORY

2. GUI_UPLOAD

3. DIRECTORY_LIST_FILES

Thanks,

Hi,

I don't know if exit a standard FM, but you can build one custom that uses external command (un a linux enviorement you could use th command whereis). For external opereting system command you can see the SM69 transaction.

I hope it can help you.

Bye

I assume you want a server side directory listing. I had to write my own class to do this. It uses Kernel calls (use with caution!) to read the server directory.

method get_directory_listing.

My exporting parameter is a table type for a structure that I copied from EPSFILI. I made the filename and filesize parameters larger:

Original:

Filename type CHAR 40

Filesize type INT4

Copy:

Filename type CHAR 175

Filesize type FLTP Len 16 Decimal 16
