2.2.7 Batch Control Tab

Select the Batch Control tab to work with the Batch Control Files.

Batch control is a special feature of the LANSA Repository. Batch control logic is used to define how a numeric field in one file is totaled into the field of another file. This can be used as a means of verifying totals during, say, an order entry.

Batch control logic in files 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.
