It appears that a stored process object that is inserted into an EG project references the absolute metadata path (specific folder name and stored process name). This is beneficial when you want to replace an existing stored process with a new stored process for all locations where that stored process is referenced. However, this means that if the SAS folder path or stored process name changes, all references to that stored process now result in an error. Having the option to reference a specific metadata id that is associated with a registered stored process would allow for organizational changes to the storage location of a specific stored process without destroying the stored process references in every EG project.
