  The SAP error message /SCWM/GM051 Mixed storage not allowed in storage type &1. GR not possible typically occurs in the context of Warehouse Management (WM) or Extended Warehouse Management (EWM) when trying to perform a Goods Receipt (GR) into a storage type that does not allow mixed storage of different product types or characteristics.
  Cause:
  
  Storage Type Configuration: The storage type in question (&1) is configured to disallow mixed storage. This means that it can only hold one type of product or material at a time.
  Product Characteristics: The product you are trying to receive may have characteristics (like batch, serial number, or other attributes) that are not compatible with the existing products in that storage type.
  Warehouse Management Settings: The settings in the warehouse management system may have been defined to prevent mixed storage for operational reasons, such as inventory management, picking efficiency, or compliance.
  
  Solution:
  
  
  Check Storage Type Configuration:
  
  Go to the configuration settings for the storage type in question. You can do this via transaction code SPRO and navigating to the relevant section for Warehouse Management.
  Look for the settings related to mixed storage and see if it can be modified to allow mixed storage if that aligns with your business processes.
  
  
  
  Review Product Characteristics:
  
  Ensure that the product you are trying to receive does not have conflicting characteristics with the products already stored in that storage type.
  If necessary, consider using a different storage type that allows mixed storage or is more appropriate for the product being received.
  
  
  
  Use Alternative Storage Types:
  
  If mixed storage is not allowed in the current storage type and cannot be changed, consider using a different storage type that permits mixed storage for the goods you are trying to receive.
  
  
  
  Consult with Warehouse Management Team:
  
  If you are unsure about the implications of changing storage type settings or if you need to maintain the current configuration for operational reasons, consult with your warehouse management or logistics team.
  
  
  
  Check for Open Transactions:
  
  Ensure that there are no open transactions or stock movements that might be affecting the ability to perform a GR in that storage type.
