• What is the cause and solution for SAP error message RSAPI_CTC247 - Logical system &1 must be mapped to Logical System &2 in BDLS UI ?

  The SAP error message RSAPI_CTC247 indicates that there is a mismatch in the logical system mapping during a data conversion or system copy process. This error typically occurs when you are trying to execute the BDLS (Batch Data Language Switch) transaction, which is used to change logical system names in the database.
  Cause:
  The error occurs when the logical system specified in the operation is not correctly mapped to the target logical system. This can happen due to:
  
  Missing Mapping: The logical system you are trying to convert does not have a corresponding entry in the mapping table.
  Incorrect Configuration: The logical system configuration in the system is not set up correctly.
  Data Inconsistency: There may be inconsistencies in the logical system definitions in the source and target systems.
  
  Solution:
  To resolve the RSAPI_CTC247 error, follow these steps:
  
  
  Check Logical System Configuration:
  
  Go to transaction BDLS.
  Check the logical system names that are configured in your system. Ensure that both the source and target logical systems are correctly defined.
  
  
  
  Mapping Logical Systems:
  
  In the BDLS transaction, you need to ensure that the logical system mappings are correctly set up.
  You can do this by going to the BDLS transaction and selecting the option to maintain logical system mappings.
  Ensure that the mapping for the logical system &1 (source) to logical system &2 (target) is defined.
  
  
  
  Update Mapping Table:
  
  If the mapping does not exist, you can create a new entry in the mapping table.
  Use the following steps:
  
  Go to transaction BDLS.
  Select the option to maintain logical system mappings.
  Add the necessary mapping for the logical systems.
  
  
  
  
  
  Re-run the BDLS Process:
  
  After ensuring that the mappings are correct, re-run the BDLS process to see if the error persists.
  
  
  
  Check for Other Errors:
  
  If the error continues, check for any other related errors or logs that might provide additional context.
