Smartsheet workflows cannot reference Summary Sheet fields as triggers or conditions. When attempting to use summary fields in a time-based workflow (e.g., via curly braces), the system returns an error stating that the fields do not exist on the sheet. This is because workflows only recognize column fields within the sheet, and inbound cell-links or cross-sheet formulas do not trigger workflow actions. This limitation prevents automation based on high-level summary data, which could be valuable for reporting and operational triggers.
Suggested Enhancement:
Enable workflows to recognize and utilize Summary Sheet fields as valid references for triggers and conditions. This would allow users to automate actions based on aggregated or calculated data, improving flexibility and reducing manual oversight.
