Define Storage Location Control

Using the assignment table (plant / storage location -> warehouse number), you can have several storage locations managed in one warehouse number . If several storage locations are managed in a warehouse number, the storage location (as well as other data) must now be entered in Warehouse Management transactions where, up to now, only the entry of a plant was necessary.

In this section, you will find notes on the procedure.

Example

Below is a list of some possible scenarios in this area:

  • Scenario 1: 1 storage location for each plant in a warehouse number
For this scenario, you do not need to configure further Customizing settings for the warehouse number, other than the assignment of the plant / storage location combination. In the Warehouse Management transactions, no entries are required in the field for the storage location since the storage location can always be determined by the system from the values for the warehouse number and the plant.
  • Scenario 2: Several storage locations for each plant in a warehouse number
The storage location shows the actual owner of the stocks. Goods movements between the storage locations are initiated solely through postings in Inventory Management. For this scenario, you must assign the respective plant / storage location combinations for the warehouse number. Further Customizing activities are not necessary for this. With this scenario, automatic determination of the storage location from the Customizing parameters is no longer possible in the Warehouse Management system. If transfer orders are created with reference to the delivery or to the transfer requirement, the storage location is determined. If you have manual transfer orders without reference to a reference document, the storage location must now be entered in addition to the plant. In inventory processing, this is also necessary if stock is found in a storage bin but it does not exist in the system.
  • Scenario 3: Several storage locations for each plant in a warehouse number, where the stock is managed at interim storage level in other storage locations as warehouse stock.
Here are two examples with the respective Customizing parameters:
  • Example 1:
Stock that is located in the goods receipt interim storage area is maintained in storage location 0090 in plant 0001. As soon as the goods are physically located in the warehouse, the stock is reposted in plant 0001, storage location 0091. The purpose of this kind of scenario can be, for exmaple, to have the goods available for deliveries only when goods receipt processing is complete. This can be achieved in this scenario if the deliveries only use the stocks in storage location 0091.
The following Customizing settings are required for this: storage locations 0090 and 0091 in plant 0001 are assigned to warehouse number 001. Storage location 0091 is marked as standard storage location ; the indicator is set for storage location 0090 so that it is not copied into the transfer requirement. You define for interim storge type 902 that the stocks in plant 0001 in this storage type should belong to storage location 0090 and that the posting change should be an accumulated posting. We will use the example of a goods receipt for a purchase order to display how this Customizing area works:
In Inventory Management a goods receipt is posted in plant 0001, storage location 0090 for purchase order 45000011. In Warehouse Management a quant is created by this posting in the goods receipt interim storage area 902 in storage bin 45000011. The storage location in the quant is 0090. At the same time, a transfer requirement is created by the posting. Since, in storage location 0090, the indicator for not having the storage location adopted in the transfer requirement is set, the transfer requirement does not have a storage location. For this reason, the standard storage location 0091 is taken as the storage location when the transfer requirement is converted into a transfer order. In the goods receipt interim storage area 902 in storage bin 45000011, the transfer order creates a negative quant that contains storage location 0091 and a positive quant in the warehouse itself, also with storage location 0091.
When the transfer order is confirmed, a posting change of the stock must take place in Inventory Management (storage location to storage location).
General notes on posting changes:
The time of the posting change is determined by the indicator "Cumulate posting change" in Customizing.
If this indicator is set, the posting change is created by the program RLLQ0100 , which can be planned as a background job or executed manually using Transaction LQ01 . If this indicator is not set, the posting change takes place in the background immediately after the transfer order has been confirmed. If you have set transfer orders with immediate confirmation, the posting change takes place immediately after the transfer order has been created.
In both cases, the posting change takes place in Inventory Management with the defined movement type "storage location to storage location". If you have the mail indicator set, a mail is sent - in the case of an error - to the user entered in the mail control. In both cases, the available quantity of the quant undergoes a posting change. The change applies to quants whose storge location is different from the one in Customizing (V_T320A) defined for this storage type. The posting change takes place directly at storage bin 45000011 (storage type 902), whereby both quants that exist there are deleted. As a rule, no posting change notice is created. Thiskind of posting change can only take place in storage types that are suitable for direct postings from Inventory Management. This is checked in Customizing in the storage type control.
This procedure is only used for available stocks. In the case of transfer requirements for stock types Q quality inspection stock, R blocked stock returns, and S blocked stock, the storage location is always copied into the transfer requirement. Accordingly, the transfer order is placed into this storage location. There is no posting change in Inventory Management. We recommend in these cases that you execute the posting change together with the posting change to unrestricted-use stock.
  • Example 2:
Stocks that are actually in production are managed in storage location 0092 in plant 0001. Stocks in the warehouse are managed in storage location 0091 / plant 0001. As soon as the goods are physically in production, the stock is reposted in plant 0001, storage location 0092. The following example assumes that the WM-PP interface is active and that stocks that have been made available by Warehouse Management are in storage type 100.
The following Customizing settings are required for this: storage locations 0091 and 0092 in plant 0001 are assigned to warehouse number 001. Storage location 0091 is designated as the standard storage location. For storage location 0092 you have set the indicator that the storage location is not copied into the transfer requirement. You define for production storage type 100 that the stock of this storage type belongs in plant 0001, storage location 0092 and that the posting change is to take place as an accumulated posting. This Customizing configuration gives the following procedure for material staging for a production order.
In the component of the production order, plant 0001 and storage location 0092 are entered. The storage location of the respective supply area is also 0092. The material staging takes place for production order 10000011. In Warehouse Management, a transfer requirement is automatically created through this material staging. Since you have set the indicator for storage location 0092 that the storage location is not copied into the transfer requirement, the transfer requirement has no storage location. For this reason, the standard storage location 0091 is determined as the storage location during transfer order creation. This means that only (1) quants in the warehouse (storage location 0091 are selected for stock removal (picking). A positive quant is created in storage type 100 with storage location 0091 through the transfer order.
When the transfer order has been confirmed, you must execute a posting change for the stock in Inventory Management. Through this posting change, the quant in storage type 100 (storage location 0091) is deleted and a new quant is created with storage location 0092. The subsequent goods issue posting for the production order also takes place from storage location 0092 and thus reduces the stock of the quant
In this scenario, make sure that at the time when the production order is released no stock of the material is in storage location 0092. In this case, the availability check must only take place at plant level.
General data on posting changes:
As described above, the time of the posting change is controlled by the indicator "Cumulate posting change". The posting change is executed using the program RLLQ0100 or Transaction LQ01.
As a rule, the available quantity of the quantity is always included in the posting change. You also change quants whose storage location is different from the storage location defined in Customizing for the storage type. The posting change takes place directly in the storage bin of the quant; both quants there are deleted by this.
Here, too, no posting change notice is created. This type of posting change can therefore only take place in storage types for which direct postings from Inventory Management are suitable.

Requirements

The component MM-IM (Inventory Management) is implemented.

Recommendation

SAP recommends that you manage only one storage location within a plant in a warehouse number.

Activities

1. Decide whether you want to manage several storage locations within a plant in a warehouse number.
2. Storage location reference
You can assign a two-digit, freely selectable storage type reference to the combination PLANT / STORAGE LOCATION. This storage location reference is used in two places in the Warehouse Management system:
a) The storage location reference is used by the system to determine the WM movement type for an IM posting. It is thus possible to determine different movement types within the WM system for the various storage locations and thus to execute postings to different interim storage types.
b) Also, the storage type reference is used for the storage type search. In this way, it is possible both during stock placement as well as during stock removals to select different storage types dependent on the storage location.
3. Control of assignment "Plant / storage location - warehouse number"
In the IMG chapter "Corporate structure", you define which storage locations are assigned to warehouse numbers. In this section, you enter the required control parameters for the assignments.
4. Storage location control in Warehouse Management
Using the storage location control function, you can define whether posting changes are to be accumulated or which user is to be informed by Mail if an error occurs. For more information on the subject "Mail" or background processing, refer to the IMG chapter Automatic TO creation.
