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

RSDS231 - Overview

• 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.,
