This error can occur when there are problems with the configuration or execution of the initial load process.
  Cause:
  
  Configuration Issues: Incorrect settings in the SLT configuration can lead to this error. This includes issues with the source and target system connections, data mapping, or transformation rules.
  Data Consistency: If the data in the source system is inconsistent or if there are issues with the data model, it can cause the initial load to fail.

  Network Connectivity: Ensure that there are no network issues between the source and target systems. Check firewalls, VPNs, and other network configurations.
  User Authorizations: Verify that the user executing the initial load has the necessary authorizations to perform the operation in both the source and target systems.
