How To Fix RSDS231 - &1: Data type &2 is not suitable for external sources

SAP Error Message - Details

• Message type: E = Error

• Message class: RSDS - New DataSource

• Message number: 231

• Message text: &1: Data type &2 is not suitable for external sources

What causes this issue?

Decimal floating point numbers should be created in DEC or DF34_RAW
format.
The format DF34_RAW is created in the database as a normal DEC. This
leads to data loss.
The formats DF16_SCL and DF34_SCL require an additional INT2 field for
the mantissa, which is not supplied by external sources.
The formats DF16_DEC and DF16_RAW provide less information than a normal
DEC field. Therefore a DEC field of the same length can be used instead.

• What is the cause and solution for SAP error message RSDS231 - &1: Data type &2 is not suitable for external sources ?

  The SAP error message RSDS231 typically indicates that there is a mismatch between the data type defined in the DataSource and the data type of the external source (like a database or file) that you are trying to connect to. This error often occurs when the DataSource is configured to expect a certain data type, but the actual data being retrieved from the external source does not match that expectation.
  Cause:
  
  Data Type Mismatch: The data type defined in the DataSource does not match the data type of the corresponding field in the external source. For example, if the DataSource expects a numeric type but the external source provides a string, this error can occur.
  Incorrect DataSource Configuration: The DataSource may be incorrectly configured, leading to an expectation of a data type that is not present in the external source.
  Changes in External Source: If the structure of the external source has changed (e.g., a column type was modified), it may lead to this error.
  
  Solution:
  
  
  Check DataSource Configuration: Review the DataSource configuration in SAP. Ensure that the data types defined in the DataSource match the data types in the external source. You can do this by:
  
  Going to the DataSource in the SAP BW system.
  Checking the field definitions and their corresponding data types.
  
  
  
  Adjust Data Types: If there is a mismatch, you may need to adjust the data types in the DataSource to match those in the external source. This can involve:
  
  Modifying the DataSource to change the data type of the affected field.
  If necessary, create a new DataSource with the correct data types.
  
  
  
  Check External Source Structure: Verify the structure of the external source to ensure that it has not changed. If it has, you may need to update the DataSource accordingly.
  
  
  Test the Connection: After making changes, test the connection to the external source to ensure that the error is resolved.
  
  
  Consult Documentation: If you are unsure about the correct data types, consult the documentation for both SAP and the external source to understand the expected data types.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  DataSource Documentation: Review the documentation for the specific DataSource you are using to understand its expected data types and configurations.
  Community Forums: Consider searching or posting in SAP community forums for additional insights from other users who may have encountered the same issue.
  
  By following these steps, you should be able to identify the cause of the RSDS231 error and implement a suitable solution.
