• What is the cause and solution for SAP error message LT020 - Always specify the requirement type for dynamic bins ?

  The SAP error message LT020, which states "Always specify the requirement type for dynamic bins," typically occurs in the context of warehouse management and inventory handling in SAP. This error is related to the use of dynamic bins in the warehouse management system (WMS) where the system requires a specific requirement type to be defined for the operation being performed.
  Cause:
  The error arises when:
  
  Dynamic Bins: You are trying to perform a warehouse task or transfer order that involves dynamic bins, but the system does not have a requirement type specified.
  Configuration Issues: The configuration for the warehouse or the specific movement type may not be set up correctly to handle dynamic bins.
  Missing Data: The necessary data for the requirement type is missing or not properly maintained in the system.
  
  Solution:
  To resolve the LT020 error, you can take the following steps:
  
  
  Specify Requirement Type:
  
  When creating or processing a transfer order or warehouse task, ensure that you specify the requirement type for the dynamic bins. This can usually be done in the transaction where you are processing the warehouse activity.
  
  
  
  Check Configuration:
  
  Go to the configuration settings in SAP for Warehouse Management (WM) and ensure that the requirement types for dynamic bins are properly defined.
  You can check the configuration in the following path:
  
  SPRO ? Logistics Execution ? Warehouse Management ? Define Requirement Types
  
  
  Ensure that the requirement types are linked to the appropriate movement types and that they are active.
  
  
  
  Review Movement Types:
  
  Check the movement types associated with the warehouse tasks or transfer orders you are trying to process. Ensure that they are configured to work with dynamic bins.
  
  
  
  Data Maintenance:
  
  Ensure that all necessary master data (like material master, storage bin master, etc.) is correctly maintained and that there are no missing entries that could lead to this error.
  
  
  
  Testing:
  
  After making the necessary changes, test the process again to see if the error persists. If it does, further investigation into the specific transaction and data being used may be required.
  
  
  
  Related Information:
  
  Dynamic Bins: These are bins that do not have a fixed location for storage and can change based on the inventory and storage needs. They are often used in high-volume warehouses to optimize space and efficiency.
  Requirement Types: These are used in SAP to determine how inventory is managed and moved within the warehouse. They define the rules for stock placement and retrieval.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as LT01 (Create Transfer Order), LT10 (Transfer Order Confirmation), and others that may be involved in warehouse operations.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP documentation for more detailed troubleshooting specific to your system configuration.
