Describe the bug
@SundareshSankaran For some reason, when I have the SYNTHETIC_DATA_FLAG for both the original data and synthetic data (from the Tabular GAN custom step) as Numeric, this custom step still fails. There was an instance where my initial CAS in-memory table was having Character fields, but when it passed through the custom step, it generated VARCHAR fields. So that also throws up an error.
To Reproduce
Steps to reproduce the behavior:
- Original dataset (with / without SYNTHETIC_DATA_FLAG) in inputtable1
- Synthetically generated data from SDG - Train a Synthetic Data Generator through GANs.step in inputtable2
- Run step.
- See error
Expected behavior
Code runs fine.

Environment (please complete the following information):
- Name of custom step SDG - Generate Distribution Comparison.step
- SAS Viya version 2025.04
