Our client faces a similar issue. The customer uses the “Reserve from current line” option in the sales order, which results in automatic reservation of serial numbers. However, the employees who handle the sales orders and those who handle the warehouse shipments work in different departments and often in different physical locations. When the warehouse employee processes the shipment, they don’t always pick the same serial numbers that were originally reserved — they select the actual serial numbers that are physically available or easiest to access at the time of shipment.The test case is the following:1.      Create an Item with the following setup:·      Enable Serial Number Tracking.·      Assign a Service Item Group Code so that a Service Item is automatically created when the item is posted in a shipment.2.      Create a purchase order for ten pieces of the item and post a warehouse receipt for serial numbers from SN4_1 to SN4_10.3.      Create a sales order for five pieces and make a reservation for five pieces. 4.      Create warehouse shipment with quantity to ship 3 pieces and in item tracking lines take serial numbers SN4_8, SN4_9 and SN4_10.In this case after posting the shipment these serial numbers are not recorded correctly in the service item.The issue is caused by tracking serial numbers in the warehouse shipment line different from those that are initially recorded with the reservation (SN4_1 to SN4_5).
