variable path for up/downloading file

former_member182371 — Fri, 10 Jun 2005 06:49:12 GMT

Hi,

i´ve developed a report that reads a file from a folder (input folder), then processes the data and finally deletes this file (from input folder) and downloads it to a new folder (output folder).

If user decides to use a new path for up/download how can i control this new situation? via a table storing different paths?

Any suggestion will be welcomed.

Best regards.

Hi,

Have a parameter for the 'file path' in the selection screen of the report and provide f4 help for that field, if the user changes the value by choosing f4 option, the changed value will be available in the parameter field, that can be passed to the function module used to download the file.

Rgds,

Hi,

what i´m trying to control is to avoid modifying the program when the up/download path changes.

The user would rather prefer modifying an entry in a table and not the program.

Best regards.

Hi everyone,

you're right, I've faced this issue several times before, and this is how I achieved it:

The thing is, I ask for 2 paths: input file and error in output file. Then I code some f4* routines. Then I upload the input file (f4_carga_fichero), do the processing, and finally I loop at the records with error and download these records via form descarga_fichero_errores.

I hope it helps. BR,

Alvaro
