• What is the cause and solution for SAP error message RS_ADSO_MODEL129 - '&1' is a field; 'Characteristic as key figure' not possible ?

  The SAP error message RS_ADSO_MODEL129 indicates that there is an issue with the data model configuration in an SAP BW/4HANA or SAP BW system, specifically related to the use of characteristics and key figures in an Advanced DataStore Object (ADSO). The message states that a certain field (represented by '&1') is being treated as a characteristic, but it is not possible to use it as a key figure.
  Cause:
  The error typically arises from the following scenarios:
  
  Incorrect Field Definition: A field that is defined as a characteristic in the ADSO is being used or treated as a key figure. In SAP BW, characteristics are typically used for dimensions, while key figures are used for measures.
  Modeling Error: There may be a modeling error in the ADSO where the field is incorrectly configured in the data model.
  Data Type Mismatch: The data type of the field may not be compatible with the expected data type for key figures.
  
  Solution:
  To resolve the RS_ADSO_MODEL129 error, you can take the following steps:
  
  
  Check Field Definitions:
  
  Go to the ADSO definition in the SAP BW modeling tools.
  Verify the field definitions and ensure that the field in question is correctly defined as either a characteristic or a key figure.
  
  
  
  Adjust the Data Model:
  
  If the field is intended to be a key figure, change its definition in the ADSO to reflect that.
  If it is meant to be a characteristic, ensure that it is not being used in a context that requires a key figure.
  
  
  
  Review Data Types:
  
  Check the data types of the fields in the ADSO. Ensure that the field intended to be a key figure is of a numeric type (e.g., Integer, Decimal) and not a string or other non-numeric type.
  
  
  
  Rebuild the ADSO:
  
  If necessary, you may need to delete and recreate the ADSO or make adjustments to the existing one to ensure that the configuration aligns with the intended use of the fields.
  
  
  
  Check for Dependencies:
  
  Review any transformations or data flows that may be using this ADSO to ensure that they are not causing conflicts with the field definitions.
