If you set this indicator, the system allows you to post negative quants to the corresponding storage type

If you execute movements in the Warehouse Management System (WMS), which require interim storage areas, the total stock in Inventory Management (MM-IM) and in WMS must remain the same. This is possible by posting negative stock to the interim storage area.

You use this field mainly for interim storage areas.

You can set whether the system issues an error message (E), a warning (W), or no message (blank) when you post negative stock. You can do this in the Customizing for Warehouse Management under Interfaces -> Inventory Management -> Allow Negative Stocks in Interim Storage Types -> Control of System Messages in Warehouse Management.

1. You define the message type using the parameter MSV in the user master record:

2. In the SAP Menu, choose System -> User profile -> Own data.

3. Choose the tab page Parameters

4. Enter MSV in the field Parameters and enter the value with which you wish to group a certain user (for example 01) in the field Value.

5. In the IMG for Warehouse Management, choose Interfaces -> Inventory Management -> Allow Negative Stocks in Interim Storage Types -> Control of System Messages in Warehouse Management.

6. Create a new entry with the version number you selected (Value) and enter the desired system reaction in the field Message type (E, W, or blank).

Activate Storage Type SearchTCODE: OMLY

Activate Storage Type Search

For putaway or pick operations, the Warehouse Management System (WMS) must know:

into which storage types materials can be placed

The system must now determine in which storage type the material should be put away and Pickaway.

from which storage types materials can be removed

3. Furthermore, you can influence the storage type search using other indicators:

process indicator (for example, stock placement or removal)

To reduce the number of entries, you can define an access strategy for the storage type search table. With the help of this access strategy, the system determines the required entries in the storage type search table as follows:

The system first tries to find a suitable match, that is, an entry in the storage type search table with all the relevant indicators from the material master and, if available, from the hazardous material master.

If the system does not find a suitable entry in the storage type search table, it again tries to read this table, but this time using the access strategy.

Actions

Set the required parameters for the "Storage type search" in the specified sequence:

1. Storage type indicator

In the WMS, a storage type is determined as follows:

1. In the case of a putaway, you generally know where the material for the putaway is coming from. In the case of a pick, you generally know to where the material to be removed is to be transferred.

Information on the location from where the material is to be picked is either stored in the transfer requirement or determined by the system using the WM movement type.

2. The system must then know into which storage type the material should be placed, or from which storage type the material should be removed.  The table "Storage type search", which you are setting here, provides this information.  In this table, you store the preferred sequence of storage types to be searched for the material for putaways or picks.

If you have activated the storage unit check, this check also influences the storage type search.  In this case, the storage unit type from the transfer order is also checked against the allowed storage units per storage type.  The system finds this information via the table "Allowed storage unit types / storage type", which you are also setting here.

For further information on this subject, refer to the chapter Storage type search.

storage type indicator from the material master

stock category indicator

special stock indicator

storage class

water pollution class (WPC)

reference movement type

The indicators storage class and water pollution class influence the storage type search. If you are not implementing Hazardous Material Management, you do not need to pay attention to these parameters.

For information on how to activate Hazardous Material Management, refer to the chapter Hazardous materials".

4. As mentioned above, different indicators influence the storage type search.  If, however, you are using storage type indicators and you also have materials with different stock categories or materials with different special stocks, the number of required entries in the storage type search table can become quite large.

Using the storage type indicator, you can ensure that certain materials are only removed from certain storage types or placed into certain storage types in the order of preference you have defined.

You define the valid storage type indicators in the table for "Storage type indicators".

2. Storage type search

Now define the sequence of storage types to be searched by the system for stock putaway and stock pick proposals.

Make sure that you enter the correct indicators for stock putaway and stock pick in the appropriate column.

3. Movement type references

4. Access optimization for storage type search

Activate Storage Bin Type Search

If you want the system to search through the entire warehouse number for a stock pick, enter "***" (stands for stringent FIFO) as the storage type. The system will then search the entire warehouse for the oldest stock of the material. The entry "+++" means that the system branches to the user exit to the stringent FIFO process ( MWMTO013).

If you are using the 2-step picking procedure, make sure that the destination storage type of the pick step is used as the source storage type for distributing the accumulated quantities. For the storage type search with the 2-step picking process, define activity type "2" (Column " Activity").

In the Warehouse Management component, you can set up the system so that for each WM movement type certain storage types are proposed. If you want to use this mechanism, set up the necessary reference movement types for the movement types concerned. These reference movement types must be taken into account in the table "Storage type search".

Instructions for access strategy for the storage type search table

The Warehouse Management System (WMS) can manage different sizes of storage bins within a storage type.  The storage bins are determined during the storage bin search:

, the transfer order item must be confirmed.

This indicator determines the capacity check that will be carried out for the storage bins in this storage type

If the load capacity of a storage bin is limited, you must make sure that the material weight or quantity of a putaway does not exceed this limit (or is other than the palletization data defined for SUT 1 in the material master record). You need to set this indicator, therefore, for storage types where this can happen. If this danger does not exist (for example, in the goods receipt area), you should not set the indicator.

This indicator controls whether the system permits changes to the destination storage bin during confirmation of the transfer order.

If you set this indicator, the system permits you, under certain circumstances, to change the destination storage bin when you confirm a transfer order.

If you do not set this indicator, the system does not allow you to change the destination storage bin when you confirm a transfer order.

Use

The following conditions apply for the possible indicators for storage types in which Storage Unit Management is active:

For more information on the prerequisites, see the SAP Libraray under Warehouse Management -> Stock Movements -> Transfer Order -> Confirming Transfer Orders -> Confirm Transfer Order.

An entry in this field means that several quants can be stored in a storage bin in this storage type.

The storage of several different quants in a bin includes materials with different features (for example, different batches) as well as different materials altogether. Without Storage Unit Management, only one quant exists for each item.

"___"  Mixed storage is not allowed

All storage units in a storage bin must contain the same       material and batch (one quant).

" A "  Several Storage units with the same material per bin

       Several different materials or batches of a material may occupy

       a storage bin at the same time. However, the individual storage

       units must contain the same material and/or batch number.

" B "  Several batches per bin and storage unit

       Only one material number may occupy a bin. However,

       if the material requires a batch number, more than one batch

       of this material may be stored in the bin. Each storage unit

       may also contain more than one batch of the same material.

" C "  Several batches per bin

       Only one material may occupy a bin. However, if the material

       requires a batch number, different batches of the same material

       may occupy the bin. You are not allowed to store different

       batches in a single storage unit.

" X "  Mixed storage without restrictions

       Several material numbers as well as different batches may exist

       in both the storage bin and in individual storage units.

Use

Define Storage Bin Types

Actions

1. Decide whether you want to use the "Storage bin type search".

2. Create your bin types with the corresponding names.

In the Warehouse Management system, you can block the following units for stock placements and stock removals:

You can divide your storage bins into groups (for example, large storage bins, small storage bins, and so on).  A suitable storage bin is proposed by the system during stock placement in combination with the storage unit type.
