• What is the cause and solution for SAP error message LTR2_CHANGELOG101 - Source of &1 changed ?

  The SAP error message LTR2_CHANGELOG101 with the description "Source of &1 changed" typically occurs in the context of SAP Landscape Transformation (SLT) when there is a change in the source system that affects the data replication process. This error indicates that the source table or the structure of the data being replicated has changed, which can disrupt the replication process.
  Cause:
  
  Schema Changes: Changes in the source database schema, such as adding or removing columns, changing data types, or modifying constraints.
  Table Structure Changes: Modifications to the source table structure that are not compatible with the existing replication setup.
  Data Source Configuration Changes: Changes in the configuration of the data source in SLT that affect how data is being captured or replicated.
  
  Solution:
  To resolve the LTR2_CHANGELOG101 error, you can follow these steps:
  
  
  Check Source System Changes:
  
  Review any recent changes made to the source system, including schema modifications, table alterations, or data type changes.
  Ensure that the changes are compatible with the SLT configuration.
  
  
  
  Adjust SLT Configuration:
  
  If the source structure has changed, you may need to adjust the SLT configuration to accommodate these changes.
  You can do this by reconfiguring the data replication settings in the SLT system.
  
  
  
  Reinitialize the Replication:
  
  In some cases, it may be necessary to reinitialize the replication for the affected table. This involves stopping the replication, deleting the existing data in the target, and then starting the replication process again.
  Use transaction code LTRC to manage the replication settings and reinitialize if needed.
  
  
  
  Check for Errors in SLT Logs:
  
  Review the SLT logs for any additional error messages or warnings that may provide more context about the issue.
  Use transaction code LTRC to access the logs and monitor the replication status.
