Warehouse Activity Monitor (WAM) can report problems with Warehouse Management (WM) objects, and it also allows you to do follow-up functions to help you fix them. Learn how to use WAM most effectively in your WM implementation with these tips.
Key Concept
Warehouse Activity Monitor (WAM) can serve as a reporting mechanism for all functions within the warehouse and also can help identify issues related to incomplete documents ahead of time. This saves a lot of time and money when doing reconciliations for Warehouse Management (WM) stocks and also by maintaining the status of WM objects accurately in your SAP system. In addition, WAM helps reduce user errors immediately after a WM implementation by monitoring key objects and preventing a build-up of incomplete transactions. WAM was added to WM Release 4.0 and is used in most WM implementations beginning with this version.
It is very common for users of SAP Warehouse Management (WM) to be frustrated with the number of incomplete documents, such as unconfirmed transfer orders (TOs), open transfer requirements (TRs), and open posting change notices. This is mostly because it takes time for WM users to get used to the document and data flows. The answer to these document problems is the Warehouse Activity Monitor (WAM).

WAM is a tool that, if used effectively in an SAP WM environment, helps prevent incomplete transactions that could result in costly WM stock reconciliations. It allows users to monitor critical WM objects for incompletion or lack of activity and to do follow-up actions to complete the documents. The objects that WAM monitors are:

• Unconfirmed TOs

• Open TRs

• Open posting change notices

• Critical deliveries

• Negative stocks

• Interim storage stock, without movement

Access this tool via transaction LL01. Before you can use it, however, you need to complete the configuration in the IMG via menu path Logistics Execution>Warehouse Management>Planning and Monitoring>Warehouse Activity Monitor. Once I’ve given you the configuration instructions, I’ll provide some tips to make this tool more effective.
