Critical Stock

Definition

With this task, the warehouse activity monitor can display

stock in an interim storage area

negative stock

Use

The display of critical stock in interim storage areas makes it possible for you to identify goods

movements that have not been fully processed within an acceptable period of time.

Stock in Interim Storage Areas

The warehouse activity monitor displays stock in interim storage areas that has not moved within

the time parameters defined in the system.

Stock that exists in interim storage areas always indicates incomplete processes. Therefore, any

stock that remains in interim storage areas for a lengthy period of time is considered to be critical.

For stock in interim storage areas, the warehouse activity monitor can display the following open

processes:

Critical stock in the interim shipping area for deliveries

This can mean that there are open goods issues for materials that have not yet been delivered.

Stock in the interim storage area for differences



This can indicate discrepancies (from taking inventory or when confirming transfer orders) that have

not yet been cleared.

Stock in the interim storage area for posting changes

This means that there may be posting change notices that have not been fully processed.

Stock in the interim area for goods receipts

This indicates that there may be goods that have not yet been stored in the warehouse.

Negative Stock

The warehouse activity monitor displays all negative stock that has exceeded the critical time period

defined in the system.

The existence of negative stock also indicates incomplete processes that can be displayed by the

warehouse activity monitor. For example, these can include:

posting change notices that are not completely processed

goods receipts processed in WM that were not yet posted in IM

Criteria

For critical stock, you define the critical time period for each warehouse number and movement

type in Customizing. Additionally, you can define whether all stock or only stock in dynamic storage

bins is to be monitored.

Additional Functions

Using the warehouse activity monitor, you can carry out the following additional function for critical

stock:



For a critical material, you can display all transfer orders that correspond to the critical quant.

In many cases, this makes it possible to determine the reason the critical situation occurred.

Frequently, no transfer order exists for a critical stock in an interim storage area. In this case, you

can be certain that the critical situation was caused by an IM posting.

Goods Receipt Without Previous Goods Receipt Posting in IM

Purpose

You put goods away by creating a transfer order in the Warehouse Management system (LE-WM)

first, without posting a goods receipt in Inventory Management (MM-IM) first.

Prerequisites

You use SAP Inventory Management (MM-IM).

You have made the following settings in the Customizing for Warehouse Management:

You have not set the indicator TR (for automatic creation of transfer requirement) for the relevant

WM reference movement type under Interfaces ® Inventory Management ® Define Movement Types

® LE-WM Interface inventory management.

You use a special movement indicator for when you want to make an exception and activate

automatic transfer requirement creation for this movement type. To do this, define a new

movement type, assign a special movement indicator to the new movement type and set the

indicator TB (for automatic creation of transfer requirement)

Negative stock is allowed in the interface storage type.

To do this, choose the menu path Master Data ® Define Storage Type in the Customizing for

Warehouse Management and set the indicator Allow negative stock.

Process Flow



The goods to be put away are in the goods receipt interim storage area of your warehouse.

You create a transfer order for goods putaway.

When you create the transfer order, the system determines the storage bin for the material on the

basis of a predefined search strategy.

The system creates a negative quant in the goods receipt interim storage area.

You put away the goods from the goods receipt interim storage area in one or more storage bins,

based on the transfer order.

You confirm the transfer order and enter any differences.

Once you confirm the transfer order, the goods are available in the system.

You can find additional information on entering differences under handling differences.

You post the goods receipt in Inventory Management (MM-IM).

When you post the goods receipt, you increase the stock and clear the negative quant in the goods

receipt interim storage area, and a positive quant is created in the destination storage bin for the

material.

Result

The goods receipt process is complete.

Handling Differences

Use

It is possible that you discover stock differences in your warehouse, for example, during inventory or

when you are executing a stock transfer.



In a stock transfer, you confirm more goods or less goods than provided for in the transfer order.

Goods turn up at an expected location.

A storage bin is discovered to be empty although there should actually be material in it.

Prerequisites

You have assigned the difference indicator for storage bins in Customizing for Warehouse

Management under the path Activities ® Confirmation. Here you define to which storage type and

storage bin the stock difference is to be posted. There are three different ways to specify storage

bins for a difference indicator:

You assign a pre-defined bin coordinate.

The system debits the specified storage bin with the difference in the column Diff.SB.

You assign a dynamic bin coordinate.

If you set the indicator TO, the system generates the storage bin coordinate on the basis of the

transfer order number, should a difference occur during confirmation.

You assign the source storage bin as a bin coordinate to the transfer order item.

If you set the indicator Srce bin, the system debits the source storage bin of the movement type with

the stock difference.

If the source storage type does not allow negative stock balances, the system checks whether the

stock balance is going to be negative (see Negative Stock Check).

If you use this type of difference indicator, the transfer order item cannot contain a return quantity.

Furthermore, you cannot use this difference indicator for stock picks from bulk storage areas.

Features



In the Warehouse Management System (WMS), you can classify stock differences by cause (for

example, breakage, theft) using the difference indicator.

If you determine discrepancies during the confirmation process, you post the difference quantity toa logical interim storage type. The interim storage type is not a physical location since it does not

occupy space in a warehouse; it serves merely as a type of clearing account.

In order to ensure that you have the same stock levels in Inventory Management (IM) and

Warehouse Management (WM), you must pass on to Inventory Management all the stock

differences that you determine in WM and subsequently correct them using the difference storage

type (see also Clearing Differences).

In the standard version of the Warehouse Management System (WMS), the following two

movement types are defined for handling differences:

For differences where the quantity does not exist in the storage bin but is recorded in the books, usemovement type 711. In this case, the difference must be cleared from the warehouse and posted to

the interim storage type for differences.

For differences where the quantity does exist in the storage bin but is not recorded in the books, use

movement type 712. In this case the difference must be cleared from the interim storage type for

differences and posted to the warehouse.

As soon as you have confirmed the transfer order item, the system posts the difference to the

storage bin that has been specified for the respective difference indicator.

Activities

You create a transfer order with a movement type that is provided for handling differences. The

system posts the respective quant to the interim storage type for differences.

After you have posted the difference quantity to the interim storage type for differences, you can

clear it from there as an inventory difference and then post the quantity to inventory management.
