Understanding Control Table Merges
Control Table Workbench runs the batch applications for the planned merges that update the data dictionary, user defined codes (UDCs), Solution Explorer, and other control tables. It then updates the Table Conversion Scheduler table (F98405) to indicate completion, and writes a conversion log record to the Table Conversion - History Log table (F984052).
Note: The number of control tables to be
merged varies, depending on the upgrade being performed. Your Control Table
Workbench form may list fewer or more tables than shown in the figure above. If you
used Solution Explorer task tables in a previous release, disable R9000C before
running the Control Table Workbench.
