Running your processes in batch mode via a scheduler would give you a greater level of control. You can arrange so that if a "project" fails then following steps don't run. You can also use the SAS option SYNTAXCHECK to immediately stop processing any more data once an error occurs. In batch mode you get a full log all processes and it is very easy to locate errors (with simple text searches) and then to fix them.
Of course the down side is you would have to export your projects to SAS code to run in batch mode.
