    • Negative or zero quantity: The system does not accept zero or negative quantities in the given context.
    • Incorrect unit of measure: The quantity entered does not match the expected unit of measure or conversion factors.
    • Configuration restrictions: Customizing or validation rules in the system restrict certain quantities.
    • Document or transaction type restrictions: Certain document types or transaction types may only allow specific quantity ranges.

    Solution:

    To resolve the error, consider the following steps:

    1. Check the quantity entered:

      • Ensure the quantity is positive and within the allowed range.
      • Verify that the quantity does not exceed available stock or limits set in the system.
    2. Verify unit of measure:

      • Confirm that the quantity is entered in the correct unit of measure.
      • Check if any unit conversion is required and correctly applied.

      • Run stock reports or use transaction codes like MMBE (Stock Overview) to confirm availability.
