plsql- creating a custom table and grant access to apps schema and production read only user

Whenever a custom table is created as XX01.XX_EMP_DATA; i.e XX01 schema

Then this table should be grant to apps schema

GRANT ALL ON XX_EMP_DATA TO APPS;

GRANT SELECT ON XX_EMP_DATA  TO APPS_RO;

above APPS_RO is the production read only and APPS is the schema

Instead of apps an USER_NAME can also be given access to specific user
