AL11 Directory - File Save

Hello Gurus,

I have written SAP ABAP program which calls FM 'SAP_TO_CSV_CONVERT'

to convert internal table data to .CSV Format.

I use OPEN and CLOSE Dataset to place the File in AL11.

Filepath/Filename is '/usr/sap/trans/Credit Limit Interface for UK- File FTP

Old files should not be replaced , but each time a new file has to be generated and placed in the folder when program is run

to place file in AL11

Please help me on this.

Thanks
