Allow documents with Stamps or Annotations ECM-I-1128
Credit to @fredmeissner for doing the testing/discovery.
Shedding further light on the inconsistent interface between ERP and ECM, it seems there is no control that will allow the inclusion of stamps or annotations to be included on document retrieval.
I explained a bit more on the Idea post, but if you use them inside ECM you may want to upvote this one.
