Stored Process Manager

Sas Enterprise Guide provides a wizard named the Stored Process Manager that guides the user through the steps of creating a stored process.
The wizard automatically

  • adds the %STPBEGIN and %STPEND statements
  • saves the code in the stored process code repository
  • registers the stored process in the metadata repository.

SAS Enterprise Guide is the preferred way to develop and test stored processes in SAS®9 because, you can create and test the program in one application.
Stored processes can be created from a variety of sources, including

  • tasks that have been added to the project
  • existing SAS programs.

SAS Enterprise Guide uses the Create New Stored Process Wizard.

Create a Stored Process from an Existing Program

The Stored Process Manager in SAS Enterprise Guide can be used to create a stored processes from existing SAS code. The wizard will scan the code for macro variables and lead you through a process of creating parameters from them. This greatly simplifies the process of creating stored processes from legacy code. To begin, add the existing program to the project.
15. Select File Ð Open Ð From My Computer….
16. Navigate to C:Workshopwinsassbiovr and select customerlist.sas:
Select Open. The code is displayed and added to the
