• What is the cause and solution for SAP error message LT086 - Mixed storage A and P only appropriate for storage unit management ?

  The SAP error message LT086 indicates that there is a mixed storage issue in the context of Storage Unit Management (SUM) in the Warehouse Management (WM) module. Specifically, it suggests that the system has encountered a situation where both storage types A (unrestricted stock) and P (blocked stock) are being used in a way that is not compatible with the current configuration of the warehouse.
  Cause:
  The error typically arises due to the following reasons:
  
  Mixed Storage Configuration: The warehouse is configured to allow mixed storage, but the specific storage types (A and P) are not set up to be mixed together.
  Storage Type Settings: The settings for the storage types in the warehouse management configuration may not allow for the combination of unrestricted and blocked stock in the same storage unit.
  Stock Type Restrictions: The system may have restrictions on how different stock types can be stored together, leading to conflicts when trying to process movements or transactions involving both types.
  
  Solution:
  To resolve the LT086 error, consider the following steps:
  
  
  Check Storage Type Configuration:
  
  Go to the Warehouse Management settings in SAP and review the configuration for the storage types involved (A and P).
  Ensure that the settings allow for mixed storage if that is the intended behavior.
  
  
  
  Adjust Mixed Storage Settings:
  
  If mixed storage is not desired, you may need to adjust the stock placement or movement strategies to ensure that A and P stocks are stored in separate storage units or locations.
  
  
  
  Review Stock Movements:
  
  Check the stock movements that are being attempted when the error occurs. Ensure that the movement type being used is appropriate for the stock types involved.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to Warehouse Management and Storage Unit Management for specific guidelines on configuring mixed storage.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the error no longer occurs and that stock movements can be processed as expected.
  
  
  
  Consult with SAP Support:
  
  If the issue persists after checking configurations and settings, consider reaching out to SAP support for further assistance.

  Warehouse Management Documentation: Familiarize yourself with the SAP Warehouse Management documentation for best practices on managing storage types and stock movements.
  User Forums and Communities: Engaging with SAP user communities or forums can provide insights from other users who may have encountered similar issues.
