open & copy text file between AL11 directories
we have files arriving on usr/sap/tmp directory . We need to copy the last of these files arriving each evening on the usr/SAP/files directory with a standard naming convention to load them into BW. The name of the file arriving on usr/sap/tmp is every day different eg. G30981 - G30982- G30990. How can we do it with an abap program ?
