Connecting to and accessing table in SQL database where there are multiple schemas

[Kim_SOM]

I have been granted access to tables in a data warehouse.  When I use software such as DBeaver, I can open the tables I need. I need to analyze the data using SAS and I can't access the tables. 

Here's the warehouse setup:

1. Database ABCD
   1. Schemas
      1.       A
      2.       B
      3.       C
         1. Table_1
         2. Table_2
         3. Table_3

libname statement 

libname A1 postgres server="XXXXXXXXXX" port=5432

 user=usrname pwd='XXXXX'  database=abcd;

SAS LOG:

NOTE: Libref abcd was successfully assigned as follows:
Engine: POSTGRES
Physical Name: XXXXXXXXXX

SAS Code:
Proc contents data=a1._all_;
run;

SAS LOG:

ERROR: File A1.Table1 does not exist.

I am not sure what other libname options I need. 

Your help is greatly appreciated.

Did you try the Schema option?

LIBNAME Statement for the PostgreSQL Engine 

SCHEMA= LIBNAME Statement Option

Thank you -- that seems to work. I will have to test it.
I appreciate the quick response
