• What is the cause and solution for SAP error message LTR2_BASIS201 - Only root tables are supported for selection ?

  The SAP error message LTR2_BASIS201: Only root tables are supported for selection typically occurs in the context of SAP Landscape Transformation (SLT) when trying to configure or execute a data replication task. This error indicates that the system is expecting a root table (a table that does not have any parent tables in the context of the data model) for the selection criteria, but a non-root table has been specified.
  Cause:
  
  Non-root Table Selection: The most common cause of this error is that the user is trying to select a non-root table for replication. In SLT, only root tables can be used as the starting point for data replication.
  Incorrect Configuration: There may be a misconfiguration in the SLT setup where a non-root table is mistakenly included in the replication configuration.
  Hierarchy Issues: If the table is part of a hierarchy and is not defined correctly in the data model, it can lead to this error.
  
  Solution:
  
  Identify the Root Table: Check the data model to identify the root table associated with the non-root table you are trying to select. You can use transaction codes like SE11 (Data Dictionary) to explore the table relationships.
  Modify the Replication Configuration: Update the SLT configuration to ensure that only root tables are selected for replication. Remove any non-root tables from the selection.
  Check Table Relationships: Ensure that the relationships between tables are correctly defined in the data model. If necessary, adjust the model to reflect the correct hierarchy.
  Consult Documentation: Refer to the SAP documentation for SLT to understand the requirements and limitations regarding table selection for replication.
