  The SAP error message M8393 indicates that there is a cross-company code transaction issue in a Purchase Order (PO) item. This error typically arises when you attempt to create or process a purchase order that involves multiple company codes, which is not allowed in certain configurations or scenarios.
  Cause:
  
  Cross-Company Code Transactions: The error occurs when a purchase order item is associated with different company codes. SAP does not allow cross-company code transactions for certain types of purchase orders, especially if the configuration does not support it.
  Configuration Settings: The system settings may not be configured to allow cross-company code transactions. This can be due to settings in the purchasing organization, company code, or other related configurations.

  Solution:
  
  Check Purchase Order Configuration: Ensure that the purchase order is set up correctly and that all items belong to the same company code. If you need to create a cross-company code transaction, consider using intercompany purchasing processes.
  Review Company Code Settings: Verify the configuration settings for the company codes involved. Ensure that the purchasing organization is assigned correctly to the company codes and that the necessary settings for cross-company transactions are enabled.
  Vendor and Material Master Data: Check the vendor and material master data to ensure they are correctly set up for the relevant company codes. Make sure that the vendor is assigned to the correct company code and that the material is available for the intended company code.
  Use Intercompany Purchase Orders: If cross-company transactions are necessary, consider using intercompany purchase orders, which are specifically designed to handle transactions between different company codes.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific configuration settings related to cross-company code transactions.
