• What is the cause and solution for SAP error message LT170 - Function exit for stock rmvl only together with strategies ' ' or F ?

  The SAP error message LT170 indicates that there is an issue with the stock removal process in the Warehouse Management (WM) module, specifically when trying to execute a stock removal for a material that is not allowed to be removed under certain conditions. This error typically arises when the system is configured to use specific strategies for stock removal, and the current strategy does not meet the requirements for the operation being performed.
  Cause:
  The error message LT170 is triggered when:
  
  Stock Removal Strategy: The stock removal strategy defined for the material or storage type is not compatible with the operation being performed. The strategies may include options like FIFO (First In, First Out), LIFO (Last In, First Out), or others.
  Empty Strategy: The error specifically mentions that the function exit for stock removal is only valid when using certain strategies, and it seems that an empty strategy (' ') or an invalid strategy ('F') is being used.
  Configuration Issues: There may be configuration issues in the Warehouse Management settings that need to be addressed.
  
  Solution:
  To resolve the LT170 error, you can take the following steps:
  
  
  Check Stock Removal Strategy:
  
  Go to the configuration settings for Warehouse Management and check the stock removal strategies assigned to the relevant storage types or materials.

  Review Material Master Data:
  
  Check the material master data for the affected materials to ensure that the stock removal strategy is correctly assigned.

  Adjust Warehouse Management Settings:
  
  If necessary, adjust the settings in the Warehouse Management configuration (transaction SPRO) to ensure that valid stock removal strategies are in place.
  You may need to consult with your SAP WM configuration team to ensure that the strategies align with your business processes.
