How To Fix AUR048 - Weighting total is zero; extrapolation is not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: AUR - Unbilled Revenue Reporting and Mass Simulation

• Message number: 048

• Message text: Weighting total is zero; extrapolation is not possible

What causes this issue?

A bill line with weighting key &V1& should be extrapolated for the
extrapolation of a billing document. However, the weighting total for
this weighting is zero in the billing period of the document (&V2& to
&V3&).

System Response

The billing document cannot be extrapolated for a simulation period.

How to fix this error?

Maintain the weighting for weighting key &V1&.

Procedure for System Administrators

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

• What is the cause and solution for SAP error message AUR048 - Weighting total is zero; extrapolation is not possible ?

  The SAP error message AUR048, which states "Weighting total is zero; extrapolation is not possible," typically occurs in the context of the SAP Advanced Planning and Optimization (APO) module, particularly during demand planning or forecasting processes. This error indicates that the system is unable to perform extrapolation because the total weighting of the data being analyzed is zero. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Zero Weighting: The most common cause of this error is that the weights assigned to the historical data points are all zero. This can happen if:
  
  The data used for forecasting does not have any valid historical values.
  The weights have been incorrectly configured or calculated.
  There are no relevant data points available for the forecast period.
  
  
  
  Data Issues: Missing or incomplete data can lead to a situation where the system cannot calculate a valid weighting total.
  
  
  Configuration Errors: Incorrect settings in the forecasting model or planning book can also lead to this issue.
  
  
  Solutions:
  
  
  Check Historical Data: Ensure that there is sufficient historical data available for the product or planning object. If historical data is missing, you may need to input or retrieve it.
  
  
  Review Weighting Configuration: 
  
  Check the configuration of the forecasting model to ensure that the weights are set correctly.
  If you are using a custom forecasting model, verify that the logic for calculating weights is functioning as intended.
  
  
  
  Adjust Forecasting Parameters: 
  
  Modify the parameters of the forecasting model to ensure that it can handle the available data.
  Consider using different forecasting methods that may be more suitable for the data at hand.
  
  
  
  Data Cleansing: Clean the data to remove any anomalies or outliers that may be affecting the weighting calculations.
  
  
  Consult Documentation: Review SAP documentation or help resources related to the specific forecasting model you are using to ensure that all settings are correct.
  
  
  Testing: After making adjustments, run a test forecast to see if the error persists. 
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed. Other users may have encountered the same error and can provide insights or solutions.
  Training and Documentation: Ensure that users involved in the forecasting process are adequately trained on the tools and processes to minimize errors related to data input and configuration.
  
  By addressing the underlying causes of the zero weighting total, you should be able to resolve the AUR048 error and successfully perform extrapolation in your SAP system.
