WM370 - Details

• The SAP error message WM370 indicates that a listing procedure has already been exclusively assigned to a specific function, which prevents you from assigning it again to another function. This error typically occurs in the context of Warehouse Management (WM) when dealing with listing procedures for stock management.
  
  Cause:
  The error arises when you attempt to assign a listing procedure that is already exclusively linked to another function (e.g., picking, putaway, etc.). In SAP WM, listing procedures are used to control the visibility of stock based on certain criteria, and each procedure can only be assigned to one function at a time.
  
  Solution:
  To resolve the WM370 error, you can take the following steps:
  
  
  Check Existing Assignments:
  
  Go to the transaction code SPRO to access the SAP Customizing Implementation Guide.
  Navigate to the relevant path for Warehouse Management and check the listing procedures assigned to different functions.
  Identify the function that currently has the listing procedure assigned.
  
  
  
  Reassign or
