  The SAP error message IUUC_MAIN163 indicates that the system is unable to determine the logging table identifier for a specific table (denoted as &1 in the error message). This typically occurs in the context of SAP Landscape Transformation (SLT) or when using Change Data Capture (CDC) mechanisms.
  Cause:
  
  Missing Configuration: The logging table for the specified table may not be configured correctly in the SLT system.

  Technical Settings: There may be issues with the technical settings of the table in the source system, such as missing primary keys or incorrect data types.

  Check SLT Configuration:
