• What is the cause and solution for SAP error message LTR2_RN_CHECK049 - No mapping built yet ?

  The SAP error message LTR2_RN_CHECK049: No mapping built yet typically occurs in the context of SAP Landscape Transformation (SLT) or Data Replication processes. This error indicates that there is an attempt to replicate data or perform a transformation, but the necessary mapping between the source and target systems has not been established or configured.
  Cause:
  
  Missing Mapping Configuration: The most common cause is that the mapping between the source and target tables has not been defined in the SLT configuration.
  Incomplete Setup: The SLT configuration might be incomplete, meaning that the necessary steps to create the mapping have not been followed.
  Technical Issues: There could be technical issues or inconsistencies in the SLT setup that prevent the mapping from being recognized.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the SLT configuration transaction (usually LTRC).
  Verify that the mapping for the relevant tables is correctly set up. You can do this by checking the "Table Mapping" section.
  If the mapping is missing, you will need to create it.
  
  
  
  Create or Adjust Mapping:
  
  If no mapping exists, create a new mapping for the source and target tables.
  Ensure that the field mappings are correctly defined, including any transformations that may be necessary.
  
  
  
  Activate the Configuration:
  
  After creating or adjusting the mapping, ensure that the configuration is activated. This is often done in the same SLT configuration transaction.
  
  
  
  Check for Errors:
  
  After making changes, check for any other error messages or logs that might indicate further issues with the SLT setup.
  
  
  
  Restart Replication:
  
  Once the mapping is correctly set up and activated, restart the replication process to see if the error persists.
