MUF_ACCOUNTING (MFY)

This table is for the Accounting Facility. It provides the startup information and the current information about each Accounting table. One row exists for each Accounting table defined as a startup option.

Before Version 12.0, you could perform certain kinds of maintenance (inserts and deletes) on this table, but beginning with Version 12.0, that functionality has been moved to the SQL_CONSOLE (SQX) Dynamic System Table.
