• What is the cause and solution for SAP error message /SAPAPO/SRC128 - Forecast delivery schedule stopped due to tolerance violation ?

  The SAP error message /SAPAPO/SRC128 Forecast delivery schedule stopped due to tolerance violation typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is a discrepancy between the forecasted demand and the actual delivery schedule that exceeds predefined tolerances. This can happen in various scenarios, such as during the planning process or when executing a forecast.
  Cause:
  
  Tolerance Settings: The system has specific tolerance settings for forecast delivery schedules. If the actual delivery deviates from the forecast by more than the allowed tolerance, the system will stop the forecast delivery schedule.
  Data Inconsistencies: There may be inconsistencies in the data, such as incorrect forecast values, delivery quantities, or other related parameters.
  Configuration Issues: The configuration settings for tolerances in the APO system may not be aligned with business requirements, leading to frequent violations.
  Changes in Demand: Sudden changes in demand or supply chain disruptions can lead to significant deviations from the forecast.
  
  Solution:
  
  Review Tolerance Settings: Check the tolerance settings in the APO system. You may need to adjust these settings to allow for greater flexibility in the forecast delivery schedule.
  
  Navigate to the relevant configuration settings in the SAP system (usually found in the APO configuration area).
