  The SAP error message RS_HCPR_MODEL123 indicates that there is an issue with the internal type of a field in a data model, specifically when working with the SAP HANA Calculation Views or similar data modeling scenarios. The error message provides placeholders for specific details:
  
  &1: The name of the field that is causing the issue.
  &2: The invalid internal type that is being referenced.
  &3: The length of the field.

  Cause
  This error typically arises due to one of the following reasons:
  
  
  Data Type Mismatch: The field in question is expected to have a certain data type, but the actual data type being used is incompatible. For example, a field might be expected to be of type DECIMAL, but it is being treated as STRING or another type.
  
  
  Model Configuration Issues: There may be a misconfiguration in the data model or calculation view where the field definitions do not match the expected types.
  
  
  Inconsistent Metadata: If the metadata for the data source has changed (e.g., changes in the underlying database table or view), it may lead to inconsistencies in the data model.
  
  
  Incorrect Field Length or Decimal Definition: The length or decimal definition of the field may not align with what is expected in the model.
  
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check Field Definitions: Review the field definitions in the calculation view or data model. Ensure that the data types, lengths, and decimal places are correctly defined and match the source data.
  
  
  Adjust Data Types: If you find that the data type is incorrect, adjust it to the expected type. For example, if a field is defined as STRING but should be DECIMAL, change it accordingly.
  
  
  Rebuild the Model: If the model has become corrupted or misconfigured, consider rebuilding the calculation view or data model from scratch, ensuring that all field definitions are correct.
  
  
  Check Source Data: Verify the underlying data source (e.g., database table or view) to ensure that it has not changed in a way that would affect the data types or structure.
  
  
  Refresh Metadata: If there have been changes to the underlying data source, refresh the metadata in the calculation view to ensure that it reflects the current structure of the data.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for any specific notes or updates related to the version of SAP you are using, as there may be known issues or patches available.
