Bin Management Help

Hello Everyone,

We are a One World Netsuite user and new to Netsuite as of October 2012 so we are learning everyday.   In the first 8 months of using Netsuite we did not use Bin Management or Advance Bin Management features.   We are in the process of implementing a scanning system to our warehouse and we have turned the bin management feature on. 

I have run into a problem after implementing this.  When I check use bins on a item record I can add the bin location on the field and then go to the bin putaway worksheet to move the inventory to the preferred bin.   When I load the putaway worksheet it shows inventory to move into this bin but it is not the total amount of what is on hand.   For example the on hand quantity may say 24 in stock but on the bin putaway worksheet will only say 11 and I cannot figure out where the other 13 are
