Planned Cross-Docking
Purpose
Cross-Docking enables you to generate cross-docking decisions prior to the actual arrival of incoming stock and release of outgoing documents (i.e. prior to transfer order creation).
The process differs, depending on:
· Whether the cross-docking decisions involve linking document items or designating a document or item for cross-docking
· Whether the inbound TO is confirmed before or after the release of the outbound document (in the case of decisions linking items)
· Whether the document or item is an inbound or outbound document or item (in the case of cross-docking designation)
Prerequisites
...
1. Inbound and outbound deliveries/transfer requirements (TRs) are created in the system.
2. The documents have some quantity of stock available for picking or putaway.
3. You have done the following:
a. Maintained warehouse level settings in Customizing for Logistics Execution → Cross-Docking → Maintain Warehouse Level Settings. In particular, you have entered the cross-docking storage type, and defined a time reference, planning time window and default latest release time.
b. Defined warehouse movement types as being relevant for cross-docking in Customizing for Logistics Execution → Cross-Docking → Define Cross-Docking Relevancy for Movement Types
c. Ensured that the Consider Pre-Alloc. Stock indicator is not set in Customizing for Logistics Execution → Warehouse Management → Activities → Transfers → Define Movement Types
d. Ensured that the cross-docking storage type is excluded from the stringent FIFO picking strategy in Customizing for Logistics Execution → Warehouse Management → Strategies → Picking Strategies → Define Strategy for “Stringent FIFO”
e. Entered 1 (for inbound documents) or 2 (for outbound documents) in the TO Creation field (Screen Control) for your warehouse in Customizing for Logistics Execution → Warehouse Management → Activities → Transfers → Define Movement Types.
We also recommend that you ensure that the cross-docking storage type is excluded from every storage type search sequence in Customizing for Logistics Execution → Warehouse Management → Strategies → Activate Storage Type Search, to avoid a situation in which stock for cross-docking is picked for other deliveries.
Process Flow
Decisions Linking Planning and Candidate Document Items
...
|
|
Inbound |
Outbound |
|
1. |
You do any of the following: · Create a cross-docking plan consisting of one or more cross-docking decisions involving linked inbound and outbound document items. For more information, see Creating a Cross-Docking Plan. · Create the system-recommended decisions in the background. For more information, see Cross-Docking Decision Optimization. |
|
|
2. |
The stock arrives at the goods receipt area (storage type 902) and you post goods receipt, or use the partial posting functionality. |
You try to create a TO for the outbound document (i.e. release the outbound document). |
|
3. |
You create a putaway TO for each of the document items. During TO creation, the system does the following: a. Fetches the previously created decision according to the document item b. Determines the destination as: § The cross-docking storage type in a case where two-step cross-docking is forced § The goods issue area (storage type 916) in all other cases |
The system fetches the previously created decisions according to the document items.
|
|
4. |
You try to create a TO for the outbound document (i.e. release the outbound document). If the goods to be cross-docked are at the cross-docking storage type, the system automatically creates the TO from the cross-docking storage type. |
The system delays creation of picking TOs (from storage to the goods issue area) for the outbound document as long as the latest release time has not yet arrived. If the relevant inbound document items arrive before the latest release time, you perform goods receipt and create a putaway TO for each item. During TO creation, the system determines the destination as: · The cross-docking storage type in the case where two-step cross-docking is forced. Once the goods have been confirmed at the cross-docking storage type, the system will not delay the creation of a picking TO, and you can create a picking TO for the outbound document. When you create the picking TO, the system automatically creates it from the cross-docking storage type. · The goods issue area in all other cases |
Decisions Designating Documents or Items for Cross-Docking
|
|
Inbound Document/Item Designated for Cross-Docking |
Outbound Document/Item Designated for Cross-Docking |
|
1. |
You designate a document or item for cross-docking via the cross-docking monitor. For more information, see Designating a Document or Item for Cross-Docking. |
|
|
2. |
When the inbound document items arrive at the warehouse, you perform goods receipt and create a putaway TO for each of the items. |
When inbound document items containing the same materials as the relevant outbound items arrive, you perform goods receipt and create a putaway TO for each item. During TO creation, the system determines the destination as: · The cross-docking storage type in the case where two-step cross-docking is forced. Once the goods have been confirmed at the cross-docking storage type, you can create a picking TO for the outbound document. When you create the picking TO, the system automatically creates it from the cross-docking storage type. · The goods issue area in all other cases
The system does not prevent the creation of a picking TO from storage to meet the outbound material requirements. |
|
3. |
During TO creation, the system does the following: ... a. Fetches the previously created decisions b. Determines the destination as the cross-docking storage type |
|
|
4. |
A warehouse worker moves the relevant goods to the cross-docking storage type and confirms execution. |
|
|
5. |
You can manually create a picking TO from the cross-docking storage type to the goods issue area. |
