• What is the cause and solution for SAP error message RSAN_WB039 - Field cannot be aggregated ?

  The SAP error message RSAN_WB039: Field cannot be aggregated typically occurs in the context of SAP BW (Business Warehouse) when you are trying to aggregate a field that is not suitable for aggregation. This can happen in various scenarios, such as when creating queries in the Query Designer or when working with InfoProviders.
  Cause:
  The error is usually caused by one of the following reasons:
  
  
  Non-Aggregatable Field: The field you are trying to aggregate is not designed to be aggregated. For example, fields that contain text or certain types of attributes cannot be summed or averaged.
  
  
  Data Type Issues: The data type of the field may not support aggregation. For instance, character fields or certain complex data types cannot be aggregated.
  
  
  Incorrect Query Design: The query may be incorrectly designed, where the aggregation function is applied to a field that does not support it.
  
  
  Missing Aggregation Settings: The InfoObject or field may not have the correct aggregation settings defined in the data model.
  
  
  Solution:
  To resolve the RSAN_WB039 error, you can take the following steps:
  
  
  Check Field Properties: Review the properties of the field in the InfoObject. Ensure that it is set up to allow aggregation. For example, numeric fields can typically be aggregated, while text fields cannot.
  
  
  Modify Query Design: If you are using Query Designer, check the query design. Ensure that you are not trying to aggregate fields that are not meant to be aggregated. Remove or replace such fields with aggregatable ones.
  
  
  Use Aggregatable Fields: If you need to perform aggregation, ensure that you are using fields that are designed for this purpose, such as key figures (e.g., sales amount, quantity).
  
  
  Review Aggregation Settings: In the InfoProvider settings, check the aggregation settings for the fields. Make sure that the fields you want to aggregate are marked as aggregatable.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the fields and their aggregation capabilities.
  
  
  Testing: After making changes, test the query again to see if the error persists.
