Plain source does not support refresh, but you can make a YUM source out of it:

- cd to the directory with the rpms. 

- call 'createrepo -p .' (from package createrepo) which will create a directory
  repodata/ whith the XML metadata.
    
  NOTE: Different than a Plain source, createrepo will recursively scan for rpms.

- remove the source in YaST, and recreate it, using the directory where you
  called createrepo as URL


If the content of your directory changes, use createrepo to rebuild the
metadata. The next time YaST enables the source, the changed metadata are 
reloaded.
