This is not really a question that relates to ODS or Base Reporting procedures. Your best bet for help is to contact Tech Support. I don't really think this is possible (to import an Excel function) in a SAS dataset. Because even though a SAS dataset is composed of rows and columns and LOOKS very similar to an Excel spreadsheet, SAS operates on data with PROCEDURES and DATA STEP programs -- not with functions that are stored in the data.
