• What is the cause and solution for SAP error message IUUC_TAB021 - The following tables are classified both as customer and SAP tables: ?

  The SAP error message IUUC_TAB021 indicates that there are tables in your system that are classified as both customer tables and SAP standard tables. This situation can arise during the process of data replication or when using the SAP Landscape Transformation (SLT) tool, particularly when trying to set up or manage data replication scenarios.
  
  Cause:
  
  
  Table Classification Conflict: The error occurs when a table is defined in such a way that it is recognized as both a customer table (customized by the user) and an SAP standard table (part of the standard SAP delivery). This can happen if a customer has made modifications to a standard table or if there are conflicting definitions in the system.
  
  
  Data Replication Setup: When setting up data replication, SLT checks the classification of tables. If it finds a table that is both a customer and SAP table, it raises this error to prevent potential data inconsistencies.
