Loopback

A loopback in batch procedure is a situation where the batch execution returns to a previous step. This can happen for a variety of reasons, such as:

• A condition is not met.
• An error occurs.
• A user input is required.

A specific sequence of events needs to be repeated. Loopbacks can be used to create a variety of control execution in procedures.

Loopbacks include:

The loopback condition(s): This is the condition that must be met in order for the batch to loop back to a previous step.

The loopback step(s): This is the step that the batch returns to if the loopback condition is met.

The loopback exit condition(s): This is the condition that must be met in order for the batch to exit the loop.

Batch Recipes with loopbacks must include a loopback exit condition.
