Editing a file in the Presentation Server.

Hi, people!

I need to edit a file (one line in the middle of the file) and it's in the presentation server. By CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD or GUI_DOWNLOAD I write the file and append lines... but it's impossible for me edit one line in the middle....

Suggestions??

PS:. I need edit it out of the memory or with a small size of memory, because the file is writed step-by-step and its size is sooooooooooo BIG to put it in an internal table again.

yes , you can edit or insert but you need to know the where exactly you going to make the change .

read the file in the presentation server using gui_upload , now the rows of the file will be available in the internal table , by index access or loop the itab find the place using search string operation make necessary changes and then rewrite the file using gui_download.

Hi Evaldo,

I don't see a way of you being able to edit one line without reading the entire file into memory. You could hold the data you are writing to the file in a custom table in SAP, and when an edit is required, delete the old table and recreate a new one based on your custom table.

Best of luck.

When I said soooooooooooooo BIG, it's a file with aprox. 500 MB, 4000000 of lines...... The SAP Memory explodes! Too much information for put in an internal table again. So, I imagine which I must get only the begin of the file and try rewrite it. I don't know...

If the file is so big, u should consider to move it to Application Server.

U could have timeout problem (and memory space of course) because fm working on presentation server can work online only.
