• What is the cause and solution for SAP error message SAWE_BO_SA310 - Combination of 'no key field' and 'relevant for forecasting' not allowed ?

  The SAP error message SAWE_BO_SA310, which states "Combination of 'no key field' and 'relevant for forecasting' not allowed," typically occurs in the context of SAP's Advanced Planning and Optimization (APO) or similar modules where forecasting is involved. This error indicates that there is a configuration issue with the key fields in the planning object structure.
  Cause:
  
  
  Key Field Configuration: The error arises when a planning object structure is defined with a characteristic that is marked as "relevant for forecasting" but does not have a key field assigned. In SAP, key fields are essential for identifying unique records in the database, and if a characteristic is set to be relevant for forecasting, it must also have a key field.
  
  
  Master Data Issues: There may be inconsistencies or missing configurations in the master data that relate to the characteristics used in forecasting.
  
  
  Planning Object Structure: The planning object structure may not be correctly defined, leading to the combination of settings that SAP does not allow.
  
  
  Solution:
  
  
  Check Planning Object Structure:
  
  Go to the transaction code /SAPAPO/SDP94 or the relevant transaction for your version of SAP.
  Review the planning object structure and ensure that all characteristics marked as "relevant for forecasting" have corresponding key fields defined.
  
  
  
  Modify Characteristics:
  
  If you find a characteristic that is relevant for forecasting but does not have a key field, you will need to either:
  
  Remove the "relevant for forecasting" setting from that characteristic.
  Assign a key field to that characteristic if it is necessary for your forecasting needs.
  
  
  
  
  
  Review Master Data:
  
  Ensure that the master data associated with the planning object structure is complete and correctly configured. This includes checking the characteristics and their values.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for detailed guidance on configuring planning object structures and characteristics.
  
  
  
  Testing:
  
  After making changes, test the configuration by running the forecasting process again to ensure that the error is resolved.
