Adding RcvHead.ReceiptComment to Inventory Movement Report (Modifying RDD)

I’m on Cloud/SaaS.

I saw this thread Report Dataset for MS Report Builder - #10 by ckrusen. If the RDD is a data view and it combines all the tables in the RDD into one dataset (PartTran?), then shouldn’t I be able to just add T1.ReceiptComment in the query and field? Doesn’t work though and the error message doesn’t help either.
