Inventory Parts in Stock by previous date

Why would a company like IFS think that its not important to be able to go back in time and look at what a particular value was as of a prior date.  How can you manage a company without a days on hand inventory report.  Which you cannot get unless useless fields are filled out.  Simply idiotic and poor creation of an EDP system.  In addition, people make mistakes, they hit the wrong key, and yet for some transactions in IFS you cannot reverse what someone did, further complicating everyone’s life.  It actually takes a coding change to be able to “unlock” inventory from a Distribution Order that has gone awry.  No system is perfect, but this is worse than bad.  Our entire company is regretting going to IFS at this point.  My question is when will developers at IFS decide to make a system that actually does what a basic business needs.  Stop complicating the system, and install basic functions that are easy to use for 5th graders.
