just to work correctly, you will have to download from the net, the RFC library corresponding to your agent OS and KERNEL type on http://service.sap.com/rfc-library
extract them by sapcar (unix) or SAPCAR.exe and copy them to
after this you have to import the SAP Panel to be useable by Control-m / EM
using desktop / tools / import applications forms
browse to you installation CD the Forms directory
so stop and restart all control-m / EM components to use this newly imported SAP Panel
otherwise it is true that many other concept to see like "control-m function modules" to perform tasks not provided by SAP standards API's
does it help you ?
