I created a Geoprocessing tool using ModelBuilder against a geodatabase. In the ModelBuilder tool, I setup several parameters, including the Workspace (Geodatabase), input tables and feature class, and output table and feature class. I published the results as a Geoprocessing tool in ArcGIS Server. It runs well but some of the parameters (Workspace, Output table and class) are not displayed. How can I revise the tool to let the filtered parameters displayable? Thanks if you can help.
