Reuse of lot numbers in incoming transactions

You cannot reuse existing lot numbers in incoming transactions. This rule applies to incoming documents, such as purchase orders and sales return orders, but also less common incoming transactions like sales orders with a negative quantity.

Instead, you must create new lot numbers by using the Business Central’s functionaility for assigning lot numbers during inbound transactions. For more information, see To assign serial or lot numbers during an inbound transaction. This check ensures accurate tracking and traceability.

This rule does not apply in the following conditions:

• Consumption journal lines with a negative value in the Quantity field on the Consumption Journals page. This implies that the system allows the reuse of lot numbers for all types of consumption posting.
• Positive adjustment item journal lines with the Entry Type field value set as Positive Adjmt. and a positive value in the Quantity field on the Item Journals page. This implies that the system allows the reuse of lot numbers for all positive corrections.
• Negative adjustment item journal lines with the Entry Type field value set as Negative Adjmt. and a negative value in the Quantity field on the Item Journals page. This implies that the system allows the reuse of lot numbers for all positive corrections.
