Select the Batch Control tab to work with Batch Control.
Batch control is a special feature of the LANSA Repository. Batch control logic is used to define how a numeric column in one table is totaled into the column of another table. This can be used as a means of verifying totals during, say, an order entry.
Batch control logic in tables can improve performance by reducing the amount of database I/O.
To learn about batch control, refer to Batch Control Development in the Developer Guide.
