Hi.
I have tried everything I could think of to resolve this error. Please check my code
to find the error I have made. First time poster.

Try changing your first statement to:

create table test as select 
labchemresultnumericvalue,
LabChemTestName,Topography from

I removed the a. and b. table aliases.

Note that when you run code with explicit pass-through like this (it's a great feature to use), the code in parentheses is executed by the remote database. 

So this code:

(select labchemresultnumericvalue,
b.LabChemTestName,c.Topography from

<project name>.src.chem_labchem as a

	left join CDWWork.dim.labchemtest as  b on  
		a.LabChemTestSID=b.labchemtestsid

	left join CDWWork.dim.Topography as c  on 
		a.TopographySID=c.TopographySID;)

runs on SQL server.  SAS doesn't know about this code, and doesn't execute it.

The first part of your code which is not in the parentheses will be run by SAS:

create table test as select 
labchemresultnumericvalue,
b.LabChemTestName,c.Topography from

But  since the SAS code doesn't define an alias named a or b, it throws an error.

Thank you very much.
