Multiple Programs within an EG project

Lost_Gary — Thu, 03 Jun 2021 13:14:13 GMT

I have multiple programs within an EG project that I have on a schedule (just Windows task scheduler on my desktop). The scheduled task is to run the entire EG project (all programs). Each program is a slight variance of the other as tweaks were made to request other output. So, I have utilized the same data set names within every program. For instance, program 1 may look at q1 data and program 2 may look at q2 data, but I call the data set work.analysisdata in both programs. Is that a problem within the schedule as there is only 1 work library? or does SAS EG silo each program run so that my results will not be impacted?

Sorry - this may seem like a question too basic for this forum, but I can't seem to find that answer.

All your program nodes work in the same environment, which means that datasets with an identical name will be overwritten, and only the last version will survive.

With temporary datasets, created and used within a node only, this is not an issue, but results will only have the last one.

Does EG run each scheduled program within a project sequentially or concurrently? And if concurrently, can this cause issues with using the same dataset names?

EG can run codes in parallel, but for this, parallel processing needs to be enabled for the project, and you need to define nodes as parallel in the project flow.
