• What is the cause and solution for SAP error message L9513 - Mixing items for external and integrated warehouses not allowed ?

  The SAP error message L9513, which states "Mixing items for external and integrated warehouses not allowed," typically occurs in the context of inventory management and warehouse management processes. This error indicates that there is an attempt to mix stock items that are managed in different types of warehouses—specifically, external (or third-party) warehouses and integrated (or internal) warehouses.
  Cause:
  
  Warehouse Configuration: The system is configured to treat external and integrated warehouses differently. When you try to process a transaction that involves both types of warehouses, the system prevents this to maintain data integrity.
  Stock Type: The stock items being processed may belong to different stock types or categories that are not compatible with each other.
  Transaction Type: Certain transactions may not allow mixing of stock from different warehouse types, such as transfers, stock movements, or inventory counts.
  
  Solution:
  
  Check Warehouse Configuration: Review the configuration settings for the warehouses involved. Ensure that the items being processed are intended for the same type of warehouse.
  Separate Transactions: If you need to handle items from both external and integrated warehouses, consider separating the transactions. Process them in different steps or batches to avoid mixing.
  Review Item Master Data: Check the master data for the items involved. Ensure that they are correctly classified and assigned to the appropriate warehouse type.
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines for handling warehouse transactions to ensure compliance with best practices.
  User Authorization: Ensure that the user performing the transaction has the necessary authorizations to handle both types of warehouses if applicable.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on warehouse management configurations.
  Transaction Codes: Familiarize yourself with relevant transaction codes (e.g., MIGO for goods movements, LT01 for transfer orders) that may be involved in the process.
  Warehouse Management (WM) Module: Understanding the WM module's configuration and processes can help in troubleshooting and resolving issues related to warehouse operations.
  Training and Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
