APO_BAPI_SPP043 - Details

• The SAP error message "APO_BAPI_SPP043 Stability rule violated: No reduction in limited freeze horizon" typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with Supply Network Planning (SNP) or Production Planning and Detailed Scheduling (PP/DS). This error indicates that the stability rules defined in the planning process have been violated, specifically regarding the freeze horizon.
  
  Cause:
  
  Freeze Horizon: The freeze horizon is a time period during which changes to the planning data are restricted to ensure stability in the planning process. If a planning run attempts to make changes that would reduce the freeze horizon, this error will be triggered.
  Planning Parameters: The planning parameters set in the system may not align with the current planning situation, leading to conflicts.
  Data Changes: Changes in demand, supply, or other relevant data that fall within the freeze horizon can also trigger this error if they conflict with the stability rules.
