  The SAP error message CNV_IUUC_REPLICATION404 indicates that there is an issue with the data type being used in a replication process, specifically that the ABAP type specified (denoted by &1) is not supported by the underlying database. This error typically arises during data replication scenarios, such as those involving SAP Landscape Transformation (SLT) or other data migration tools.

  Modify Data Model: If a custom or unsupported type is being used, consider modifying the data model to use a supported type. This may involve changing the structure of the data being replicated.
  Update SLT Configuration: If you are using SLT, check the configuration settings. Ensure that the mappings and transformations are correctly set up to handle the data types.
  Database Compatibility: Verify that the database version you are using is compatible with the data types in your ABAP program. If necessary, consult the database documentation for supported types.
