Smart SAP Assistant

• What is the cause and solution for SAP error message LT198 - Strat. R is only allowed in pairs (putaway strat = R and picking str.= R) ?

  The SAP error message LT198 indicates that there is a configuration issue related to the use of storage strategies in the Warehouse Management (WM) module. Specifically, this error occurs when the putaway strategy is set to "R" (which stands for "Random Storage") but the picking strategy is not also set to "R". In SAP WM, certain strategies must be used in pairs to ensure that the system can manage inventory effectively.
  Cause:
  The error arises when:
  
  The putaway strategy is configured as "R" (Random Storage).
  The picking strategy is set to something other than "R" (e.g., "FIFO", "LIFO", etc.).
  
  In SAP WM, when you use random storage for putaway, it is expected that the picking strategy should also be random to maintain consistency in how items are stored and retrieved.
  Solution:
  To resolve this error, you need to ensure that both the putaway and picking strategies are set to "R". Here are the steps to do this:
  
  
  Check Storage Type Configuration:
  
  Go to the transaction code SPRO to access the SAP Customizing Implementation Guide.
  Navigate to Logistics Execution > Warehouse Management > Master Data > Define Storage Types.
  Find the storage type that is causing the issue and check its configuration.
  
  
  
  Adjust Picking Strategy:
  
  If the picking strategy is not set to "R", you will need to change it.
  You can do this in the same configuration area where you defined the storage types. Look for the section related to picking strategies and ensure it is set to "R" for the relevant storage type.
  
  
  
  Test the Configuration:
  
  After making the changes, perform a test putaway and picking operation to ensure that the error no longer occurs.
  
  
  
  Documentation and Training:
  
  Ensure that relevant documentation is updated to reflect the changes made.
  Train users on the importance of matching putaway and picking strategies to avoid similar issues in the future.
  
  
  
  Related Information:
  
  Storage Strategies: Understanding the different storage strategies in SAP WM is crucial. Random storage allows for more flexible inventory management but requires careful configuration.
  Warehouse Management: Familiarize yourself with the overall WM processes, including how putaway and picking strategies interact.
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional insights or updates related to this error message.
  
  By ensuring that both the putaway and picking strategies are aligned, you can effectively resolve the LT198 error and maintain smooth warehouse operations.
