This typically occurs in the context of inventory management, financial postings, or any scenario where quantities are being aggregated or compared.
  Cause:
  The error arises when the system detects that there are conflicting quantities (e.g., some quantities are positive while others are negative) in the operand specified in the error message. This can happen in various scenarios, such as:
  
  Inventory Adjustments: When trying to adjust inventory levels, if some entries are positive (additions) and others are negative (deductions), the system may not be able to process the request correctly.

  Correct the Entries: Adjust the quantities so that they are consistent. This may involve:
  
  Changing negative quantities to positive (or vice versa) if they were entered incorrectly.
  Splitting the transaction into separate entries if necessary (e.g., processing additions and deductions separately).
