Note 110702 - Palletization data in the material master

本文解释了SAP系统中物料主数据中的托盘化指令1和2的使用逻辑。当存储数量小于第二个托盘化规格时,系统建议使用第二个托盘化指令;当存储数量介于第一个和第二个托盘化指令之间时,使用第一个托盘化指令;当存储数量大于第一个托盘化指令时,系统将数量拆分,并提出第一个托盘化指令或其倍数,以及剩余部分托盘的数量。

Summary

Symptom

There are a maximum of 3 palletization specifications in the material master.
How are palletization instruction 1 and 2 are used?
It seeems that the 3rd palletization instruction is not used.

Additional key words

MLGN, palletization, bulk storage

Cause and prerequisites

Palletization instructions 1 and 2 should be defined in descending quantity. When placing in storage, the system creates full pallets of category 1. The remaining quantity is either of pallet type 2 (remaining quantity <= pallet quantity 2) or a broken pallet of category 2. The following examples illustrates the system behavior:
Example: Palletization 1 --> 10 pc for each E1
                      2 -->  5 pc for each E2

  1. 1. The quantity to be placed in storage is smaller than the 2nd palletization specification, the system proposes the 2nd palletization instruction.
    Example: Quantity 4 --> 1 x 4 pc for each E2
  1. 2. The quantity to be placed in storage is between the first and second palletization instruction, the system proposes the first palletization instruction.
    Example: Quantity 7 --> 1 x 7 pc for each E1
  1. 3. The quantity to be placed in storage is larger than the first palletization specification, the system splits it and proposes the first palletization specification or a multiple of the quantity and the second palletization for a remaining partial pallet quantity.
    Example: Quantity 12 --> 1 x 10 pc for each E1
                            1 x  2 pc for each E2
  1. 4. The quantity to be placed in storage is larger than the first palletization specification and a remaining quantity is larger than the 2nd palletization specification, the system splits it and proposes the first palletization specification or a multiple of the quantity and also the first palletization for the remaining quantity.
    Example: Quantity 39 --> 3 x 10 pc for each E1
                            1 x  9 pc for each E1

This comparatively simple logic cannot be changed in the standard system for reasons of upward compatibility. However, a user exit (MWMTO007) does exist in which you can implement any algorithms you like.
The 3rd palletizion instruction might be important in the bulk storages since in the material master only defined pallets may be placed in storage, there. For bulk storages not managed in service units the number of storage units is calculated on the location storage via the defined block structures and the found service unit category and the quantity on the block storage bin by means of the palletization specifications in the material master.

Solution

You can implement more complex palletization logics in user exit MWMTO007.

Epson码垛程序是一种用于自动化仓库管理系统的软件,它帮助将货物按照特定的规则排列成堆,常见于物流和包装行业。这类程序通常包含以下几个步骤: 1. **配置库位**: 首先,需要设置每个存储区域的位置信息和规格,以便码垛机器人知道在哪里放置物品。 2. **读取条形码或二维码**: 程序通过扫描货物上的标识来识别商品,并将其与预先设定的货品信息关联起来。 3. **路径规划**: 根据库存信息和预设的算法(如First In First Out, FIFO 或最近入最先出),计算码垛机器人的移动路径。 4. **物体定位与抓取**: 机器人根据规划路径精确抓取物品并调整到正确的堆放位置。 5. **堆叠和校验**: 按照既定的堆积规则将物品层层叠加,同时进行质量检查,确保稳定性和完整性。 6. **循环操作**: 当新的订单或入库任务到来时,程序会自动调整堆栈结构,保持系统高效运行。 以下是简单的Epson码垛程序示例(伪代码形式): ```python class Product: def __init__(self, id, size): self.id = id self.size = size def plan_palletization(products): # 初始化空堆栈 stack = [] for product in products: # 检查是否能直接堆叠 if not stack or product.size <= get_stack_top_size(stack): stack.append(product) else: # 找到合适位置插入产品 insert_product_in_stack(stack, product) return stack # ...其他辅助函数... products = [Product(1, 20), Product(2, 30)] palletized_products = plan_palletization(products)
