This error indicates that a target quantity that is being processed or entered is negative, which is not allowed in the system.

  Solution:
  
  Check Input Values: Review the input values for the target quantity field. Ensure that the value entered is zero or a positive number.
  Review Configuration: If you have access, check the configuration settings in the relevant SAP modules to ensure that negative values are not allowed where they shouldn't be.

  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on the transaction or process you are working with.
  Debugging: If the issue persists and you have the technical capability, consider debugging the transaction to identify where the negative value is being introduced.
