How To Fix XU012 - Quantity conversion for & not possible as its characteristic value < 0

SAP Error Message - Details

• Message type: E = Error

• Message class: XU - Messages for Quantity Conversion at Batch Level (Steel-AI)

• Message number: 012

• Message text: Quantity conversion for & not possible as its characteristic value < 0

What causes this issue?

The characteristic value assigned to the unit of measure is negative.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Valuate the characteristics that are relevant to quantity conversion
with a value greater than or equal to zero.
(If you valuate the characteristic with zero, the quantity conversion
between this unit of measure and the quantity stored is carried out
using the planned conversion ratio at material level.)

• What is the cause and solution for SAP error message XU012 - Quantity conversion for & not possible as its characteristic value < 0 ?

  The SAP error message XU012 indicates that there is an issue with quantity conversion in the system, specifically that the characteristic value is less than zero. This typically occurs in scenarios involving batch management, where the system is trying to convert quantities based on certain characteristics (like weight, volume, etc.) but encounters a negative value, which is not permissible.
  Cause:
  
  Negative Characteristic Value: The primary cause of this error is that the characteristic value being processed is negative. In many business scenarios, quantities should not be negative, and the system is unable to perform the conversion as a result.
  Data Entry Error: There may have been an error during data entry, where a negative value was mistakenly entered for a characteristic that should always be positive.
  Master Data Issues: The issue could also stem from incorrect or incomplete master data settings, such as in material master records or batch characteristics.
  Configuration Issues: There may be configuration settings in the system that do not allow for negative values in certain contexts.
  
  Solution:
  
  Check Characteristic Values: Review the characteristic values associated with the material or batch in question. Ensure that all values are non-negative.
  Correct Data Entry: If a negative value was entered by mistake, correct it in the relevant transaction or master data record.
  Review Master Data: Check the material master and batch characteristics to ensure they are set up correctly. Make sure that the characteristics are defined to accept only valid values.
  Configuration Review: If the issue persists, review the configuration settings related to quantity conversion and characteristics in the SAP system. Ensure that the settings align with business requirements and do not allow negative values where they are not appropriate.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling characteristic values and quantity conversions.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like MM03 (Display Material), MSC2N (Change Batch), or similar to check and modify the relevant data.
  Batch Management: If you are working with batch-managed materials, ensure that the batch characteristics are correctly defined and that the batch itself is in a valid state.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional troubleshooting steps.
  User Exits or BAdIs: If custom logic is involved in the quantity conversion process, review any user exits or BAdIs that might be affecting the behavior.
  
  By following these steps, you should be able to identify the root cause of the XU012 error and implement a solution to resolve it.
