How do you save the workflow script to data table? Usually the scripts generated by Workflow builder do look something like this (for single step)

And the whole script does include few extra things
Names Default To Here(1);
Workflow_=function({},
step_name = "Report snapshot: Big Class - Distribution of height, weight";
//Report snapshot: Big Class - Distribution of height, weight
Data Table("Big Class") << Distribution(
Continuous Distribution(Column(:height), Process Capability(0)),
Continuous Distribution(Column(:weight), Process Capability(0))
);
);
Workflow_();
Also sharing example data / workflow (or both) could definitely help. If you are not willing to share them to JMP Community, I would suggest you contact JMP Support
