  The SAP error message /SAPAPO/DMRES121 indicates that the overload specified in a demand management or resource planning context exceeds the allowable limit of 200%. This error typically arises in the Advanced Planning and Optimization (APO) module when trying to allocate resources or plan production in a way that exceeds the defined capacity constraints.
  Cause:
  
  
  Excessive Overload: The primary cause of this error is that the overload percentage specified for a resource exceeds the maximum limit of 200%. This can happen if:
  
  The planned production or demand is too high.
  The resource capacity settings are not configured correctly.
  There are incorrect or unrealistic planning parameters set in the system.
  
  
  
  Configuration Issues: The resource might not be configured properly in terms of its capacity, leading to unrealistic overload calculations.
  
  
  Data Entry Errors: Manual entries in planning or scheduling might have led to an overload being set incorrectly.
  
  
  Solution:
  
  
  Adjust Overload Settings: Review the overload percentage you are trying to set and ensure it is less than or equal to 200%. If you need to increase capacity, consider adjusting the resource's capacity settings instead.
  
  
  Review Resource Configuration: Check the configuration of the resource in the APO system:
  
  Go to the resource master data and verify the capacity settings.
  Ensure that the capacity is defined correctly and that the resource can handle the planned workload.
  
  
  
  Reassess Demand and Production Plans: Look at the demand and production plans to ensure they are realistic and achievable within the resource constraints. Adjust the plans if necessary.
  
  
  Check Planning Parameters: Review the planning parameters and settings in the APO system to ensure they are set correctly and align with your operational capabilities.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing resource overloads and capacity planning.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on capacity planning in APO.
