This error typically arises in the SAP Convergent Charging or Contract Accounts Receivable and Payable (FI-CA) modules, where certain financial transactions are restricted from being posted as negative amounts.
  Cause:
  
  Negative Amounts Not Allowed: The system is configured to prevent negative postings for certain types of transactions, such as invoices or payments.
  Transaction Type Restrictions: The specific transaction type you are using may not support negative postings due to business rules or configuration settings.
  Account Settings: The account settings in the configuration may not allow for negative postings, which can be a common restriction in financial accounting to maintain data integrity.
  Document Type Configuration: The document type associated with the transaction may not be set up to allow negative postings.
  
  Solution:
  
  Review Transaction Type: Check the transaction type you are using and confirm whether it is allowed to have negative postings. If not, consider using a different transaction type that supports the required operation.
  Adjust Configuration: If negative postings are necessary for your business process, you may need to adjust the configuration settings in the SAP system. This could involve:
  
  Modifying the account settings to allow negative postings.
  Changing the document type configuration to permit negative amounts.

  User Exits or BAdIs: If your business process requires flexibility, consider implementing user exits or Business Add-Ins (BAdIs) that allow for custom handling of transactions.
