• What is the cause and solution for SAP error message L3074 - Storage class & not allowed in storage type & ?

  The SAP error message L3074 indicates that there is a mismatch between the storage class and the storage type in the system. This error typically occurs in the context of warehouse management and inventory management when trying to perform operations related to storage bins or materials.
  Cause:
  The error message "L3074 Storage class & not allowed in storage type &" usually arises due to one of the following reasons:
  
  
  Configuration Issue: The storage class assigned to a material is not compatible with the storage type defined in the system. Each storage type can have specific storage classes that are allowed, and if a material with a certain storage class is attempted to be stored in a storage type that does not accept it, this error will occur.
  
  
  Master Data Settings: The material master data or the storage type configuration may not be set up correctly. This includes the storage class not being assigned properly in the material master or the storage type configuration.
  
  
  Warehouse Management Settings: The settings in the Warehouse Management (WM) module may not be aligned with the requirements for the specific storage type and storage class.
  
  
  Solution:
  To resolve the L3074 error, you can take the following steps:
  
  
  Check Storage Class Configuration:
  
  Go to the configuration settings for the storage type in the SAP system (Transaction code: SPRO).
  Navigate to the Warehouse Management settings and check the allowed storage classes for the specific storage type.
  Ensure that the storage class of the material you are trying to store is included in the allowed list for that storage type.
  
  
  
  Review Material Master Data:
  
  Check the material master data (Transaction code: MM03) for the material in question.
  Verify the storage class assigned to the material and ensure it is correct and compatible with the intended storage type.
  
  
  
  Adjust Warehouse Management Settings:
  
  If necessary, adjust the warehouse management settings to allow the storage class in the specified storage type.
  You may need to consult with your SAP WM configuration team to make any necessary changes.
  
  
  
  Testing:
