Peter, help out by explaining more about an EDC(Ommicom) system and how it can generate a SAS transport file? Also, be careful when using the word transport because the SAS system has a transport-format (XPORT) file structure, likely not what you are referring to, I would say.
An Internet search on search argument strings "edc", "ommiom" (and also "omnicom possibly), did not yield any useful or revealing information about your challenge.
If you have created an "export" file and you are looking to import that data into SAS, possibly using PROC IMPORT, possibly there you are discussing your challenge with having a "blank" in either the file-name itself or possibly a column name within a file.
Suggest you clarify what you are attempting to do - import external data into SAS or something else, and maybe also share any SAS error diagnostic logs (COPY and PASTE directly from your SAS session into a forum post/reply). Also, information about your SAS version, OS environment, and whether SAS is executing local/report from your computer system -- these pieces of information are also very useful for constructive feedback.
