You should double check and make sure that when you manually change the ReqDate, check all the tables that get updated at the same time.
I remember doing this once and I believe there was a difference between the Sales Order date and the PartDtl date which is used by MRP.

Subject: [Vantage] Re: Updating OrderRel.ReqDate
Solved my own problem... since this was on pre-process, the other BPM (a data directive on OrderRel) was firing to blank the dates. I put a CallContextClient.ProcessID on the data directive and all is now well.
Thanks for listening,
