Changing physical table woth work table (SAS DI 4.9)

strsljen — Mon, 20 Nov 2017 13:28:52 GMT

Hi,

I have a physical table between two SQL extract operations. I would like to change it with work table without losing transformation definitions.

I have:
extract_1 -> physical table -> extract_2

I would like to have:
extract_1 -> work_table -> extract_2

Is that possible and how?
When I just delete physical table, create work table and reconnect, I lose some mappings.

Thanks in advance!

What do you mean by work table? A non metadata registered table?
Unfortunately there is no bullet proof method AFAIK.
Before deleting the "physical table" just try to move the connectors, other than that...

Hi,

Yes, that is correct. Default output from extract job is a work table. It is quite easy to convert on the fly from work table to proper SAS table without break transformation rules in the next connected step.

However, I didn't find proper "undo" option. When I delete SAS table I have to manually create work table (right click on step1 extract job and select "Create work table") and then manually connect it to extract in step2.

By doing that mappings get pretty much smashed, on both step1 and step2 extracts.

There is an "Replace" option on the SAS table, but I didn't find the option to replace SAS table with work table, only with some other table from the SAS libraries.

So far I am doing manual crunching on each of that example where I need to remove SAS table. No need to point out I am not particularly happy about it. 🙂

So if there is a better way, please, enlighten me! 🙂

Well don't first delete, and the undo option is to undo check out.
