Hi!
I'm building a set of dataflows—one for each KPI/goal at my job. Everything works fine in the Power Query Editor, but when I check the workspace, two of the three dataflows fail with a RequestID/ActivityID error. The common factor is that the two failing dataflows reference some of the same sources, while the one that works does not.
After spending hours investigating, I think I've narrowed it down to a specific source causing the issue, but I can't figure out why it only fails in the service and not the editor. Here’s what I’ve tried so far:
- No logic/boolean calculations before handling nulls.
- No automatically-added error correction steps (like 'replace values' or 'change type').
- Referenced the source in two different ways—both failed:
- a) Combined/transformed six tables into one in my primary dataflow and merged to that.
- b) Moved the six tables into their own dataflow (which works fine in both the editor and workspace) and tried merging to that.
- I'm on a PRO space (not Premium).
- The error seems to happen at the merge step, before the expand step.
- Tried different join types (no success).
- Marked primary key columns with the official button.
- Moved everything to the Desktop app, where everything works without errors.
Any ideas what might be wrong? What else should I be looking at to fix this?
Thanks in advance!
