PLS-00487: Invalid reference to variable 'INT'

Summary:

I am trying to execute the PL/SQL proc within Package but getting error while execution as schema name is 'INT' which is a reserved keyword.

when I alter the session to set current schema as INT then it is working. I need to call this from ODI.

 BEGIN 

 INT.ETL_CONFIG_PACKAGE.INS_ETL_CONFIG_RUN_DETAILS('S2L_HOSPITALS',15); 

 END;
