Electronic apparatus and operation method thereof

An electronic apparatus for stock management, the apparatus comprising:

• a communication device;
• and
• a controller,
• wherein the controller is configured to:
• determine that expiration date-related information of an item of the stock satisfies one or more conditions;
• identify the item as a target for removal from the stock in the fulfillment center based on determining that the expiration date-related information of the item satisfies the one or more conditions, wherein quantity information of the item identifies a quantity-on-data of the item within the stock;
• transmit, via the communication device to a mobile terminal, information identifying the item as the target for removal and a removal task command, wherein, in response to the removal task command, the mobile terminal displays, via a user interface of the mobile terminal, at least a portion of the information identifying the item as the target for removal;
• in response to the removal task command, acquire, via the communication device from the user interface of the mobile terminal, information regarding a removal quantity of an actual quantity of the item to be removed from the stock in the fulfillment center, information regarding a remaining quantity of the actual quantity of the item to be maintained within the stock in the fulfillment center, and expiration date-related information of the remaining quantity of the actual quantity of the item;
• and
• update the quantity information of the item based at least in part on the remaining quantity of the actual quantity of the item to generate updated quantity information and the expiration date-related information of the item based at least in part on the expiration date-related information of the remaining quantity of the actual quantity of the item to generate updated expiration date-related information of the item, wherein the updated quantity information identifies the removal quantity of the actual quantity of the item is removed from the stock in the fulfillment center and the remaining quantity of the actual quantity of the item is maintained within the stock in the fulfillment center,
• wherein to update the quantity information of the item, the controller is further configured to, in response to the quantity-on-data of the item being greater or less than the actual quantity of the item, adjust the quantity-on-data based on the actual quantity,
• wherein to update the quantity information of the item, the controller is further configured to, in response to the quantity-on-data of the item being greater than the actual quantity of the item by a first quantity, allocate the first quantity of the quantity-on-data as stock of a predetermined location, and
• wherein to update the quantity information of the item, the controller is further configured to, in response to the quantity-on-data of the item being less than the actual quantity of the item by a second quantity, allocate a third quantity allocated as the stock of the predetermined location, to the quantity-on-data of the item.
