  The SAP error message FMITPOMC059 indicates that a document has been posted with both a customer and a vendor involved in the same transaction. This situation typically arises in financial transactions where the system detects that a single document is trying to post entries to both accounts, which is not allowed in standard SAP configurations.
  Cause:
  
  Mixed Posting: The document is attempting to post to both a customer account (receivable) and a vendor account (payable) simultaneously.
  Configuration Issues: The system may not be configured to allow mixed postings, which is a common practice in financial accounting to prevent errors and maintain clarity in accounting records.
  Incorrect Document Type: The document type used may not support mixed postings.
  
  Solution:
  
  Review the Document: Check the document in question to ensure that it is not incorrectly set up to post to both a customer and a vendor. You may need to separate the transactions into two different documents.
  Adjust Configuration: If mixed postings are necessary for your business process, you may need to adjust the configuration in the SAP system. This could involve changing settings in the Financial Accounting (FI) module.
  Use Correct Document Types: Ensure that the correct document types are being used for the transactions. For example, if you are processing a payment that involves both a customer and a vendor, consider using a different approach or document type that allows for such transactions.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific guidance on handling mixed postings in your version of SAP.

  Transaction Codes: You may want to check transaction codes like FB01 (Post Document) or FBL1N/FBL5N (Vendor/Customer Line Items) to review the entries.
  SAP Notes: Look for relevant SAP Notes that might address this specific error or provide additional guidance on handling mixed postings.
  User Exits or BAdIs: If your business process requires mixed postings, consider implementing user exits or BAdIs (Business Add-Ins) to customize the behavior of the posting process.
