• What is the cause and solution for SAP error message CNV_00001263 - Source table &1 is mapped to multiple target tables. ?

  The SAP error message CNV_00001263 indicates that a source table in a data migration or conversion process is mapped to multiple target tables. This situation typically arises during data migration projects, especially when using SAP's Data Migration tools or the SAP S/4HANA Migration Cockpit.
  Cause:
  The error occurs when:
  
  A source table is incorrectly configured to map its data to more than one target table.
  There may be a misunderstanding in the mapping logic, where the same source data is intended to populate different target structures.
  The mapping configuration might have been set up incorrectly, leading to ambiguity in how the data should be transferred.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review Mapping Configuration:
  
  Check the mapping configuration for the source table in the migration tool. Ensure that each source table is mapped to only one target table.
  If the source table is intended to populate multiple target tables, consider splitting the data into separate source tables or using a different approach to handle the data transformation.
  
  
  
  Adjust Data Mapping:
  
  If the source table needs to be split into different logical parts, create separate mappings for each part to the respective target tables.
  Ensure that the data transformation logic is clear and that each target table has a unique source mapping.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines or best practices for handling such mappings.
  
  
  
  Testing:
  
  After making changes to the mapping, perform a test migration to ensure that the error is resolved and that the data is correctly populated in the target tables.
