Posting Changes Between Storage Locations

You assign a warehouse number in the Warehouse Management system (WMS) to several storage locations in Inventory Management (MM-IM) if you store and manage stock from several sites in the same physical warehouse complex. You map each site as one storage location in the system.

Integration

You manage the storage locations at Inventory Management (MM-IM) level.

You manage the warehouse at WMS level.

Caution Caution

If you execute a stock transfer for a material within a warehouse number in Inventory Management (MM-IM), this represents a posting change in the WMS.

If you execute a stock transfer in Inventory Management (MM-IM) for a material and several warehouse numbers are involved, this represents a stock removal or putaway for the affected warehouse numbers at WMS level.

End of the caution.

Prerequisites

You have assigned the storage locations to the corresponding warehouse numbers in Customizing for Warehouse Management under Interfaces Inventory Management Define Storage Location Control Assignment Control of "Plant/Storage Location – Whse Number" .

If you assign several storage locations to a single warehouse number and only trigger goods movements between the storage locations within Inventory Management, then you do not need to make any further Customizing settings.

By assigning a storage location reference to each plant/warehouse number combination in Customizing for Warehouse Management under Interfaces Inventory Management Define Storage Location Control Storage Location Reference , you simplify the storage location related control of goods movements in the WMS. You use the storage location reference in the following two cases:

Determining the WMS movement type

For postings in Inventory Management (MM-IM), the WMS determines the relevant WMS movement type on the basis of the storage location reference. The system posts similar goods movements for different storage locations in different interim storage areas.

Determining the storage type

In Customizing for Warehouse Management under Start of the navigation path Strategies Next navigation step Activate Storage Type Search Storage Type Search Determine Search Sequence End of the navigation path , you can specify on the basis of the storage location reference that the system selects different storage types for stock removals and putaways.

Features

Mapping Ownership Structures

You can map ownership structures in the Warehouse Management system (WMS) and separate the various stocks from each other within the system, because you can assign any number of plant/storage location combinations to a warehouse number in the WMS.

For more information about the structure of storage location assignment to plants and warehouse numbers, see Warehouse Structure in the Warehouse Management System.

For example, to be able to clearly identify warehouse stock during inventory, you have to enter both the plant and the storage location in which you manage the material.

Triggering Posting Changes in Inventory Management

If you only trigger goods movements between the various storage locations from Inventory Management, then you do not need to make any further system settings in the WMS.

Managing Interim Storage Areas in Other Storage Locations

You can manage stock in interim storage areas in other storage locations than for stock within the warehouse. You use this function, for example, for availability checks if you manage your own production storage location, or if you manage stock (which is not yet available) in the goods receipt area in a storage location other than the storage location for unrestricted stock.

If you manage the interim storage areas in storage locations other than the storage types within the warehouse, transfer requirements are created for stock removal or putaway, for which no stock is available in the warehouse. In this case, the system first determines the storage location in which the stock is available and then creates a posting change, with which you execute a posting change for the stock in question from one IM storage location to another IM storage location.

You assign both storage locations to your warehouse number.
You define the storage location, in which you manage the stock in the warehouse, as the standard storage location in this warehouse number in Customizing for Warehouse Management under Interfaces Inventory Management Define Storage Location Control Assignment Control of "Plant/Storage Location – Whse Number .
For the storage location to which you have assigned the interim storage area and its stock, set the indicator Do Not Copy Storage Location in TR in Customizing for Warehouse Management under Interfaces Inventory Management Define Storage Location Control Assignment Control of "Plant/Storage Location – Whse Number" .

Automatic and Cumulative Posting Changes

You can execute these kinds of posting change:

Automatically following confirmation of the TO
Cumulatively in the background using report RLLQ0100

For cumulative posting changes, set the indicator Combine Posting Changes in Customizing for Warehouse Management under Start of the navigation path Interfaces Next navigation step Inventory Management Define Storage Location Control Storage Location Control in Warehouse Management End of the navigation path .

You can start report RLLQ0100 manually. From the SAP menu choose: Start of the navigation path Logistics Next navigation step Logistics Execution Internal Whse Processes Posting Change Direct to Bin Stock Posting Change Storage Location to Storage Location End of the navigation path .

The posting change occurs directly in the storage bin. The system does not create a posting change notice. Instead, it balances out the negative quant and the positive quant in the storage bin.

Storage Location Reference

To simplify control of the processes between the various storage locations, you can assign a two digit storage location reference to the combination of plant and storage location, which clearly identifies the storage location. The system uses the storage location reference:

To determine the WMS movement type

On the basis of the storage location reference, the system determines the WMS movement type that is assigned to the IM movement type.

This means that you can post similar goods movements for various storage locations in various interim storage areas.

To determine the storage type

You can assign various storage types for putaway and stock removal according to storage location in Customizing for Warehouse Management under Start of the navigation path Strategies Next navigation step Activate Storage Type Search Storage Type Search: Determine Search Sequence End of the navigation path .

Example

Posting Changes Between Plants and Storage Locations

Posting Change	Assignment of Plant/Storage Location Combination to Warehouse Number	What You Should Know
Posting change from plant to plant		See Posting Change from Plant to Plant
Posting change from storage location to storage location
	One storage location per plant, managed in one warehouse number.	You assign the plant/storage location combination to the warehouse number.
	Several storage locations per plant, managed in one warehouse number.	You store the material stocks from several sites in one physical warehouse complex. You can tell the owner of the material stock from the storage location. You assign each plant/storage location combination to the warehouse number. For goods movements, the WMS takes the storage location from the source reference document. If you execute a physical inventory or manual goods movement, you have to enter the storage location manually.
	Interim storage areas managed in different storage locations to storage types within the warehouse proper.	For more information, see Goods Movements from the GR Area and Material Staging for Production.
