Just a quick tip on the shared prompts in SAS Information Map Studio:

When attempting to select a previously created prompt in Information Map Studio, SAS will only display shared prompts that can be used for the type of variable you are filtering/prompting. For example, if you have a date value in Information Map Studio and you would like to include a shared prompt (my favorite, a date range, for instance) the previously created & shared date range prompt shows up. HOWEVER, if for some reason you have a numeric value that you simply thought was date (meaning SAS format date wasnt defined in the dataset or in the infomap), the shared date range prompt will NOT show up. This is EXCELLENT to ensure data/prompt type consistency, however it gave me a quick heartbeat when I thought it was something more sinister.

Another tip, you can 'preselect' the shared prompts you plan to use in the information map by going to the 'Manage Prompts' tool and adding the shared prompt here. When creating a new filter, the shared prompt is available immediately.
