• What is the cause and solution for SAP error message DMC_RT_GEN047 - RAW fields longer than 32 bytes can't be used as selection field ?

  The SAP error message DMC_RT_GEN047 indicates that you are trying to use a RAW field that exceeds 32 bytes as a selection field in a Data Management or Data Transfer context. This limitation is due to the way SAP handles selection fields, which cannot accommodate RAW fields longer than 32 bytes.
  Cause:
  The error occurs when:
  
  You attempt to use a RAW data type field that is longer than 32 bytes in a selection criteria for a query or data operation.
  The system does not support RAW fields of this length for selection purposes, leading to the error message.
  
  Solution:
  To resolve this error, consider the following approaches:
  
  
  Change the Data Type:
  
  If possible, change the data type of the field from RAW to a different type that is supported for selection fields, such as CHAR or VARCHAR, ensuring that the length does not exceed the maximum allowed.
  
  
  
  Use Substring:
  
  If you need to work with the RAW field, consider using a substring of the field that is 32 bytes or less. This can be done by creating a new field or modifying the existing logic to only use the first 32 bytes of the RAW field.
  
  
  
  Modify the Query:
  
  If you are using a query or a data extraction process, modify the query to exclude the RAW field from the selection criteria or to use a different field that meets the length requirement.
  
  
  
  Data Transformation:
  
  If you are performing data transformations, consider transforming the RAW field into a different format that can be used as a selection field.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis or ABAP team for best practices on handling RAW fields and selection criteria.
  
  
  
  Related Information:
