  The SAP error message /PLMI/BO_MBOM064: Negative value not allowed typically occurs in the context of Bill of Materials (BOM) management, particularly when dealing with quantities or values that should not be negative. This error can arise in various scenarios, such as during the creation or modification of BOMs, or when performing operations that involve quantity calculations.
  Causes:
  
  Negative Quantity Input: The most common cause is that a negative quantity has been entered in a field where only positive values are allowed (e.g., component quantity in a BOM).

  System Bugs or Inconsistencies: Occasionally, bugs or inconsistencies in the system can lead to unexpected behavior.
  
  Solutions:
  
  Check Input Values: Review the values you are entering in the BOM or related transactions. Ensure that all quantities are positive and that no negative values are being inadvertently entered.
  Review BOM Configuration: Check the configuration settings for the BOM and ensure that they are set up correctly to allow for the intended operations.
