• What is the cause and solution for SAP error message RS_ADSO_MODEL167 - Field '&1': Conversion exit not allowed because of aggregation '&2' ?

  The SAP error message RS_ADSO_MODEL167 typically occurs in the context of SAP BW (Business Warehouse) when working with Advanced DataStore Objects (ADSO). This error indicates that there is an issue with the conversion exit for a field in the context of aggregation.
  Cause:
  The error message RS_ADSO_MODEL167 is triggered when:
  
  A field in the ADSO is defined with a conversion exit that is not compatible with the aggregation settings of that field.
  The aggregation type of the field does not allow for the conversion exit to be applied. For example, if the field is set to be aggregated (like a sum or average), but the conversion exit is designed for non-aggregated values, this conflict will lead to the error.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Field Properties:
  
  Go to the Data Model of the ADSO and check the properties of the field that is causing the error (indicated by &1 in the error message).
  Verify the aggregation settings for that field. If it is set to be aggregated, consider whether it should be aggregated or if the conversion exit is necessary.
  
  
  
  Adjust Conversion Exit:
  
  If the field needs to be aggregated, you may need to remove the conversion exit or change it to one that is compatible with aggregation.
  If the conversion exit is essential for the field's functionality, consider changing the aggregation type to a non-aggregated type if that fits your data model.
  
  
  
  Rebuild the Data Model:
  
  If changes are made to the field properties, you may need to rebuild or re-activate the data model to ensure that the changes take effect.
  
  
  
  Test the Changes:
  
  After making adjustments, test the data loading or reporting process to ensure that the error no longer occurs and that the data is being processed correctly.
