2.9.7 Batch Control Tab

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.
