Within SAS 9.2 you can now create shared prompts to use across information maps and stored processes.
To get to the Shared Prompt capability from SAS Management Console:

1. Move to Folders Tab



2. Create Stored Process enter 'dummy' data for STP screens until you arrive at the Parameter Entry Screen.






3. On the parameter screen create the prompt and then select 'Save as Shared'



4. In order to use the shared prompt in Information Maps, the shared prompt must be REQUIRED. The resulting Web Report Studio reports will then show all shared prompts as required.
5. After the prompts have been created and shared ~ Cancel OUT of the STP creation screens.

Important Note: Once prompt is changed to 'Shared' there is little edit capabilities. You would need to unshare, edit, and reshare. This might affect the IMAPs that are already using the shared prompt.
