This situation starts with a pipeline in a project that was created before the 2024.09 release. The pipeline has a modeling node that does not have the parameter estimates table (OUTEST) selected for generation. An Interactive Modeling node is placed after the modeling node. I
After this environment is upgraded to the 2024.09 release, the project is upgraded and the pipeline can still show complete and successful results. If you select the Interactive Modeling node, the parameter estimates table is selected by default. This was introduced as a new feature in 2024.09. However, the parameter estimates table is missing from the Model Comparison node even when Interactive Modeling node is still the champion of the pipeline.
Since the parameter estimates table was never generated by the modeling node, it does not appear in the results for the Model Comparison node. Invalidate the pipeline and then run the pipeline again with the parameter estimates table selected for the Interactive Modeling node. The table is now available in the Model Comparison results if Interactive Modeling node is still the champion of the pipeline.
