Concerning the issue with the Table References, which was discussed in the Q&A
... there seems to be a workaround with Jmp18:
example-of-a-workflow-with-a-for-each-loop.shtml
1) use a workflow step #1 to open/create new tables:
Subset by, open(), Multi File Import ...
2) Select step #1 as Source - Workflow Step in the FOR EACH settings
3) and add as many workflow steps as you want to the For Each branch:
-> for all steps in the For Each loop, Jmp will use the the tables which were opened in step #1.
[independent of the table name which was used when recording the steps!]
