Can Users Access System when MRP is Running?
Question:  Can Users Access System when MRP is Running?

Answer:  It is fine to have users in the system at the time the MRP trigger is running.  MRP will still just use the information that is saved into this temp table at the time of the run.  Any changes to records after that point will have to be captured in the next MRP run.  Keep in mind, depending on the size of your data files, this MRP run could take hours to complete, and in addition may slow down the response time of the ManEx system during this time.  This is why many elect to run the MRP at night when traffic is the least.
