• What is the cause and solution for SAP error message IUUC_MAIN155 - &1: Invalid Object definit (only one table on first and second level) ?

  The SAP error message IUUC_MAIN155 typically indicates an issue related to the Data Replication Server (DRS) or the SAP Landscape Transformation (SLT) replication setup. This error suggests that there is an invalid object definition, specifically when the system expects a certain structure or configuration for the replication of data but finds it lacking or incorrect.
  Cause:
  
  
  Invalid Object Definition: The error message indicates that the object definition for the table being replicated is not valid. This could be due to:
  
  The table does not exist in the source or target system.
  The table structure has changed (e.g., columns added or removed) without updating the replication configuration.
  The replication setup is not correctly configured for the specific table.
  
  
  
  Replication Configuration Issues: There may be issues with the configuration of the SLT or DRS, such as:
  
  Incorrectly defined replication settings.
  Missing or incorrect mapping of fields between source and target.
  
  
  
  Single Table Limitation: The error message mentions "only one table on first and second level," which may indicate that the replication setup is expecting a specific hierarchy or relationship between tables that is not being met.
  
  
  Solution:
  
  
  Check Object Definition:
  
  Verify that the table exists in both the source and target systems.
  Ensure that the table structure is consistent between the source and target systems.
  
  
  
  Review Replication Configuration:
  
  Go to the SLT configuration and check the settings for the specific table that is causing the error.
  Ensure that the table is correctly included in the replication setup and that all necessary fields are mapped correctly.
  
  
  
  Reconfigure Replication:
  
  If there have been changes to the table structure, you may need to reconfigure the replication for that table.
  You can do this by removing the table from the replication setup and then adding it back again.
  
  
  
  Check Logs:
  
  Review the SLT logs for more detailed error messages that can provide additional context about the issue.
  Look for any warnings or errors that may indicate what specifically is causing the invalid object definition.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation for SLT and DRS for any specific guidelines or troubleshooting steps related to this error.
