  The SAP error message /SAPAPO/ESPP_PR451 indicates that the historical data for a particular key figure in the SAP Advanced Planning and Optimization (APO) module contains a high percentage of zero values. Specifically, the message states that the history consists of &1% zero values, while the limit is set at &2%. This can lead to issues in forecasting and planning, as a high percentage of zero values can skew the results and make the data less reliable.

  Consider adjusting the limits for zero values if it is justified by the business context.
  
  
  
  Data Enrichment:
  
  If applicable, enrich the historical data with additional relevant information that can help improve the forecasting accuracy.
