Interleaving in radio frequency-managed warehouses 

Use

Interleaving alleviates dead-heading in radio frequency-managed warehouses. After putaway, the forklift does not return empty to the goods receipt area to repeat its operation. Instead, the forklift operator receives a new assignment (for example, picking) upon returning. The cyclical nature of work assignment provides a continuous work flow for the forklift operator.

You can let the system propose you a transfer order for putaway or identify the transfer order for putaway by the storage unit number. After you have confirmed the transfer order for putaway, the system proposes a transfer order for picking/ replenishment from the queue to which the transfer order for putaway has been assigned.

The user exit function EXIT_SAPLLMOB_061 allows you to define further selection criteria for identifying the next transfer order to be processed for picking/ replenishment. You can determine, for example, to select a transfer order for picking with a source storage bin close to the destination storage bin of the transfer order for putaway executed before.

Note: The higher the putaway and picking areas' overlapping-level, then the greater the efficiency, which interleaving yields.

Effects on Customizing

System-guided interleaving requires assigning the operator to a queue. The queue defines the work area. The operator is only assigned to tasks, which are created for his own queue. For more information about defining queues, refer to the Implementation Guide (IMG) for Mobile Data Entry and choose RF Queue Management .

For selection by storage unit there is an option to process transfer orders not assigned to the operators queue by changing the access determination. In Customizing for Mobile Data Entry , choose RF Queue Management ->Define Queues.
