Trying to create a read-only user

Question

Our HR dept would like to have READ only access to a few tables and have asked that I create a user to allow them to pull stuff into MS Access.  Since SAPR3 owns all the tables I thought I just had to, after I created the user, as SAPR3 grant select to those few tables.  Didn't work. What did I miss?
SQL> connect system/*******
Connected.
SQL> CREATE USER "HRRPT"
  2    IDENTIFIED BY "*******"
  3    PROFILE "DEFAULT"
  4    TEMPORARY TABLESPACE "PSAPTEMP"
  5    DEFAULT TABLESPACE "PSAPUSER1D";
User created.
SQL> grant create session to hrrpt;
Grant succeeded.
SQL> connect sapr3/*******
Connected.
SQL> grant select on pevsh to hrrpt;
Grant succeeded.
SQL> connect hrrpt/*******
Connected.
SQL> desc pevsh;
ERROR:
ORA-04043: object pevsh does not exist
SQL> desc 'sapr3'.'pevsh';
SP2-0565: Illegal identifier
What am I missing?
Thanks!

Answer 1

It works here as follows:
> connect system/*****
Connected.
SQL> CREATE USER hr
  2  IDENTIFIED BY hr
  3  PROFILE "DEFAULT"
  4  TEMPORARY TABLESPACE "PSAPTEMP"
  5  DEFAULT TABLESPACE "PSAPBEN620";
User created.
SQL> grant create session to hr;
Grant succeeded.
SQL> connect sapr3/******
Connected.
SQL> GRANT SELECT
  2      ON  "SAPR3"."T000" TO "HR";
Grant succeeded.
SQL> connect hr/hr
Connected.
SQL> select count (*) from "SAPR3"."T000";
  COUNT(*)
        24
SQL> desc "SAPR3"."T000";

You need to grant explicitly including schema name.
