At the top of my stored procedure I have code that checks prerequisites for it to run successfully, and if I find any issues I want to return a custom error message, and then end the stored process gracefully. Something like "endsas" but without the error conditions associated with it.
I saw SAS Note: http://support.sas.com/kb/16/225.html which gives a workaround but it involves disabling the "Show Log" button across all stored processes which I do not want to do.
