Disable "Auto Enter" feature on RF device by delivering customized message

[Madhusudhan_MV]

Issue: Many products are discovered in incorrect storage bins.

In the course of storing items, individuals frequently misplace products into incorrect destination bins. To address this issue, following the system confirming of the putaway warehouse task, it is essential to present the destination bin to the user to which the product was dropped off via a message. Additionally, to ensure user attentiveness and accuracy, manual acknowledgment through pressing a button should be required, thereby disabling the automatic enter function of the RF device when scan button is pressed.

Below video explains - How auto enter works in RF Devices

Solution:

Step 1: Create a new structure:

and add it as a application parameter:

Step 2. Copy one of the RF screen to a new screen 907:

Step 3: Create a new step

Step 4: Create a new function code:

Step 5: Configure the Logical transaction step flow as below

Step 6: In the wrapper function of the warehouse task confirming PAI function module, populate the destination bin where the product was placed into a custom message.
