• What is the cause and solution for SAP error message IUUC_MAIN103 - Table count for &1 finished in receiver system (RFC destination &2) ?

  The SAP error message IUUC_MAIN103 indicates that there is an issue with the table count during the data transfer process to a receiver system via Remote Function Call (RFC). This error typically occurs in the context of SAP Landscape Transformation (SLT) or SAP Data Services when replicating data from a source system to a target system.
  Cause:
  The error message IUUC_MAIN103 can be caused by several factors, including:
  
  Network Issues: There may be connectivity problems between the source and target systems, leading to incomplete data transfer.
  Configuration Issues: The RFC destination may not be correctly configured, or there may be authorization issues preventing the data transfer.
  Performance Issues: The target system may be experiencing performance bottlenecks, causing delays or failures in processing the data.
  Data Consistency Issues: There may be inconsistencies in the data being replicated, such as missing or corrupted records.
  Table Locking: The target table may be locked by another process, preventing the data from being written.
  
  Solution:
  To resolve the IUUC_MAIN103 error, you can take the following steps:
  
  
  Check RFC Configuration:
  
  Verify that the RFC destination is correctly configured in the source system.
  Ensure that the user credentials used for the RFC connection have the necessary authorizations.
  
  
  
  Network Connectivity:
  
  Test the network connection between the source and target systems to ensure there are no connectivity issues.
  Use transaction SM59 to check the status of the RFC destination.
  
  
  
  Monitor Performance:
  
  Check the performance of the target system to ensure it is not overloaded.
  Use transaction ST22 to check for any dumps that may indicate performance issues.
  
  
  
  Review Logs:
  
  Check the SLT logs (transaction SLT) for any additional error messages or warnings that may provide more context about the issue.
  Look for any specific error messages related to the table being replicated.
  
  
  
  Data Consistency:
  
  Ensure that the data in the source system is consistent and does not contain any errors that could affect replication.
  If necessary, perform data cleansing or validation.
  
  
  
  Table Locking:
  
  Check if the target table is locked by another process. You can use transaction SM12 to view and manage locks.
  
  
  
  Retry the Replication:
  
  After addressing the above issues, you may need to restart the replication process for the affected table.
