• What is the cause and solution for SAP error message IUUC_MAIN112 - Mismatch error occured during import of sender data ?

  The SAP error message IUUC_MAIN112 indicates that there is a mismatch during the import of sender data in the SAP Landscape Transformation (SLT) replication process. This error typically occurs when there is a discrepancy between the data structures or data types of the source and target systems.
  Causes of IUUC_MAIN112 Error
  
  
  Data Structure Mismatch: The structure of the source table in the source system does not match the structure of the target table in the target system. This can happen if there have been changes to the source table (like adding or removing fields) that have not been replicated to the target.
  
  
  Data Type Mismatch: The data types of the fields in the source and target systems may not be compatible. For example, if a field in the source is defined as a VARCHAR and in the target as an INT, this can lead to a mismatch.
  
  
  Inconsistent Data: If there are inconsistencies in the data being replicated, such as null values or unexpected characters, this can also trigger the error.
  
  
  Configuration Issues: Incorrect configuration settings in the SLT system can lead to mismatches during data import.
  
  
  Solutions to IUUC_MAIN112 Error
  
  
  Check Data Structures: Verify that the structures of the source and target tables are identical. You can do this by comparing the table definitions in both systems. If there are discrepancies, you may need to adjust the target table structure to match the source.
  
  
  Review Data Types: Ensure that the data types of the fields in both systems are compatible. If necessary, modify the target table to align with the source table's data types.
  
  
  Data Consistency Check: Perform a data consistency check to identify any problematic records that may be causing the mismatch. You can use transaction codes like SLT_MONI to monitor the replication process and identify issues.
  
  
  Reconfigure SLT Settings: If the issue is related to configuration, review the SLT configuration settings. Ensure that the replication settings are correctly defined and that any necessary adjustments are made.
  
  
  Error Logs: Check the SLT error logs for more detailed information about the mismatch. This can provide insights into which specific records or fields are causing the issue.
  
  
  Reinitialize Replication: In some cases, it may be necessary to stop the replication, make the necessary adjustments, and then reinitialize the replication process.
  
  
  Related Information
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SLT_MONI (for monitoring SLT replication) and SLT_CONFIG (for configuration settings).
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional guidance on resolving IUUC_MAIN112 errors.
  Documentation: Refer to the official SAP documentation for SLT for detailed information on configuration, monitoring, and troubleshooting.
  
  By following these steps, you should be able to identify and resolve the IUUC_MAIN112 mismatch error during the import of sender data in SAP.
