To identify the incoming file(s), you can use the FILENAME PIPE (engine) to identifying files for processing.
WIth this information you an execute a SAS macro using a SAS DATA step to read / import your Excel document with the LIBNAME EXCEL command.
The new, incoming data can be combined with your "All data daily" file using PROC APPEND.
And, lastly, you can use the CALL SYSTEM command to move the file to another folder.
I suggest you search the SAS support http://support.sas.com/ website using these keywords - you will find SAS-hosted documentation and supplemental technical and conference topic-related reference material for your reference and use with examples.
