Since I already reopened the thread, I figure I might as well respond to this now also. It’s the same general idea, but change the first 3 as I commented below
newRow["NextDispatcherID"] = "RequestorIDHere"; //same as ReqUserId (in this case)
newRow["NextActionID"] = " "; //space
newRow["ReplyOption"] = "R"; // R for reject
newRow["ReqUserId"] = "RequestorIDHere";
newRow["RowMod"] = "U";
Implied, of course, is that I also was successful, due only to that original code from @Dragos. Turns out my widget plan failed because of a bug with UD fields. See this post:
Oh - and that extra ReqUserID field? (The one in blue in the previous post.) Totally irrelevant and a red herring. Ignore that.
