String manipulation in text mode
Hi there. I’m pulling a Proof Approvals report, where I am grouping by approverDecision to know what proofs are still pending and which ones have been reviewed/approved. It turns out that if a proof was set up as interactive, the system will lowercase the field value for approverDecision and will capitalize it if the proof was set up as static. See example screenshot:

I cannot find any string functions to use within valueexpression or something similar in text mode to normalize these fields. Any idea how to proceed here?
Current text mode grouping:
