• What is the cause and solution for SAP error message LTR2_BASIS_CHECK434 - More than one link from table &1 to table &2 defined ?

  The SAP error message LTR2_BASIS_CHECK434 indicates that there is an issue with the data model in the context of the SAP Landscape Transformation (SLT) replication setup. Specifically, it means that there are multiple links defined between two tables, which is not allowed in the context of SLT.
  Cause:
  The error occurs when:
  
  There are multiple foreign key relationships or links defined between the same pair of tables in the data model.
  This can happen due to incorrect configuration or design of the data model, where the same source table is linked to the same target table more than once.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Data Model:
  
  Review the data model in the SAP system to identify the relationships between the tables involved. You can use transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility) to analyze the table definitions and relationships.
  
  
  
  Identify Duplicate Links:
  
  Look for any duplicate foreign key relationships or links between the two tables. You may need to check the configuration in the SLT setup to see if multiple replication configurations have been created for the same source-target pair.
  
  
  
  Remove Duplicate Links:
  
  If you find multiple links, you will need to remove the duplicates. This may involve adjusting the configuration in the SLT setup or modifying the data model to ensure that only one link exists between the two tables.
  
  
  
  Reconfigure SLT:
  
  After making the necessary changes to the data model, you may need to reconfigure the SLT replication settings. This can include reinitializing the replication or adjusting the configuration settings in the SLT system.
  
  
  
  Test the Configuration:
  
  Once the changes are made, test the replication to ensure that the error is resolved and that data is being replicated correctly.
