• What is the cause and solution for SAP error message RSDS225 - &1: Conversion exit &2 can only be used for character fields ?

  The SAP error message RSDS225 indicates that there is an issue with the use of a conversion exit in a context where it is not applicable. Specifically, the message states that the conversion exit (denoted as &2) can only be used for character fields, but it is being applied to a non-character field.
  Cause:
  
  Incorrect Field Type: The primary cause of this error is that the conversion exit is being applied to a field that is not of type character (e.g., numeric or date fields). Conversion exits are designed to format or convert character data, and using them on other data types will lead to this error.
  Data Model Issues: There may be a mismatch in the data model where a character conversion exit is incorrectly assigned to a field that is not defined as a character type.
  Field Mapping Errors: In the context of data extraction or transformation (e.g., in DataSources, InfoObjects, or transformations), the mapping of fields may be incorrect, leading to the application of a conversion exit to an inappropriate field.
  
  Solution:
  
  Check Field Definitions: Review the definitions of the fields in your data model. Ensure that the field to which the conversion exit is applied is indeed a character field.
  Remove or Replace Conversion Exit: If the field is not a character field, you should either remove the conversion exit or replace it with an appropriate conversion routine that is suitable for the field's data type.
  Adjust Data Mapping: If the error occurs during data extraction or transformation, check the mapping of fields in the relevant DataSource or transformation. Ensure that the conversion exit is only applied to character fields.
  Testing: After making the necessary adjustments, test the data extraction or transformation process again to ensure that the error is resolved.
