DT342 - Details

  • Error Code: DT342

    Error Message: & and proxy object & have different numbers of columns


    Summary

    This error indicates a mismatch in the number of columns between a data table and its associated proxy object during data transfer or processing. Essentially, the system expects the data structure and the proxy object to have the same column count, but they differ.


    Root Causes

    • Mismatch in the structure definition between the source data table and the proxy object, often due to recent changes in table or proxy definitions.
    • Incorrect or outdated proxy object metadata that does not reflect the current data structure.
    • Custom code or interface enhancements where the data structure was modified but the proxy object was not updated accordingly.
    • Data extraction or transformation steps where the number of columns in the dataset changes dynamically but the proxy object remains static.
