• What is the cause and solution for SAP error message /SAPAPO/OM_ERROR320 - Field overflow when aggregating initial capacity consumption of resource ?

  The SAP error message /SAPAPO/OM_ERROR320 indicates a "Field overflow when aggregating initial capacity consumption of resource." This error typically occurs in the context of Advanced Planning and Optimization (APO) when the system attempts to aggregate capacity consumption data for a resource, and the resulting value exceeds the maximum limit that can be stored in the designated field.
  Causes:
  
  
  Data Overflow: The most common cause is that the total capacity consumption for a resource exceeds the maximum value that can be stored in the field used for aggregation. This can happen if there are large quantities of planned orders or production orders that consume a significant amount of capacity.
  
  
  Configuration Issues: Incorrect configuration of the resource or planning parameters may lead to unexpected high values during capacity calculations.
  
  
  Data Integrity Issues: There may be inconsistencies or errors in the master data or transaction data related to the resource, leading to incorrect calculations.
  
  
  Time Periods: If the aggregation is being done over a very long time period, the cumulative capacity consumption might exceed the field limits.
  
  
  Solutions:
  
  
  Check Resource Configuration: Review the configuration of the resource in question. Ensure that the capacity settings are appropriate and that the resource is not overloaded with planned orders.
  
  
  Adjust Time Periods: If possible, try to reduce the time period for which the capacity consumption is being aggregated. This can help in avoiding overflow by limiting the amount of data being processed at once.
  
  
  Review and Clean Data: Check for any inconsistencies in the master data or transaction data. Clean up any erroneous entries that might be contributing to the high capacity consumption values.
  
  
  Increase Field Size: If feasible, consider increasing the size of the field that is causing the overflow. This may require changes in the database schema and should be done with caution, ideally in consultation with SAP support or a technical consultant.
  
  
  Use Alternative Aggregation Methods: If the standard aggregation method is causing issues, explore alternative methods or tools for capacity planning that may handle larger values more effectively.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes or patches that address this specific error. There may be updates or fixes available that can resolve the issue.
  
  
  Related Information:
