L3387 - Details

• The SAP error message L3387 ("Open TRs exist. Posting change must take place at bin") typically occurs in the context of warehouse management and inventory management processes. This error indicates that there are open transfer orders (TRs) for the material in question, and as a result, the system is preventing a posting change (such as a stock transfer or adjustment) from being executed at the bin level.
  
  Cause:
  
  Open Transfer Orders: The primary cause of this error is that there are open transfer orders associated with the material in the specified storage bin. These transfer orders may be in various statuses (e.g., created, in process) and need to be completed or canceled before any changes can be made to the stock in that bin.
  Stock Management Settings: The system is configured to require that certain stock movements (like posting changes) must occur at the bin level when there are open transfer orders.
