Changing PPM Data
Updating PPM master data directly in the database can cause various errors to occur. We strongly recommend that you not make changes directly to the PPM database, and instead use the PPM user interface to make changes.
If you absolutely must update the database directly, it is important that you understand the underlying data model design before you update the tables and views associated with the Multilingual User Interface (MLU). Before you update MLU views or tables, make sure that your Oracle
NLS_LANG parameter is set to the same language as your PPM instance. As always, make it a point to check the data in the views and tables before you commit changes to the database. (For information about the PPM data model, see the Data Model Guide.)
