2. 由于1，在系统中可能会存在同物料不同的接收号对应相同的序列号。在退货时，较早的接收将不能进行退货；此问题属于系统BUG
原因官方解释为‘There is one restriction to prevent returning serials against earlier deliver, as the serial is also delivered by another later deliver transaction.'
请参考官方文档ID：Unable to Return Serialized Item, 0 choice for Serial Number LOV, FRM-40212 (文档 ID 1053770.1)

mtl_serial_numbers:物料序列号表 （使用SERIAL_NUM_STATUS lookup type , 1. 已定义但尚未使用 3.驻留在库存中 4 从库存发放 5. 在途驻留 7 在接收中 8 在WIP 中）
mtl_unit_transactions:物料事务处理控制表；（使用MTL_TRX_ISSUE_RECEIPT lookup type 1.发放 2.接收）
