ETL from Base system to LASR

Hi guys,

I'm about to take delivery of a new on prem SAS VA installation. In my previous workplace we used a 2 step method to get data loaded into SAS VA:

1. Overnight ETL to take data from corporate systems into the data warehouse

2. SAS VA Data Preparation, scheduled within the SAS VA interface.

However, I have heard that the above can all be accomplished in BASE SAS code, and wondered if anyone had an example of this and any gotcha's to look out for. In my head, I see this a just a couple of SAS data steps, but wonder if there is extra to do around metadata?

Thanks in advance

Jim

I find these steps work well:

Delete existing LASR table with PROC DATASETS
Load new LASR table using a DATA step
Run PROC METALIB to register the new LASR table

The METALIB code looks like this:

proc metalib;
   omr (library = "Visual Analytics Public LASR");
   folder       = "/Shared Data/SAS Visual Analytics/Public/LASR";
   select       = ("MyLASRTable");
   VA_Update_Rule = delete
 run;

That's great to know, thanks!
I'll come back once the environment is up, for help with the detail, if required (hope that's OK).
