In the company:
- Oracle Database
- bi-server-3.5.2

There are connections:
- conexao_01;
- conexao_02;
- conexao_03

The difference of 3 connections is the schema of the database!

- user_01_OP and user_01_GE: These users accession to conexao_01
- user_02_OP and user_02_GE: These users accession to conexao_02
- user_03_OP and user_03_GE: These users accession to conexao_03

How to make this setting in PMEs?

I thought I'd use a variable to switch the schema of the connection depending on group/user logged.
But I do not know that.
