My first request would simply be to only fill in the customer Name field in Enter Work Orders when that field is blank.  Otherwise, leave whatever is there alone. Please!?
 
Maybe it is different for some users that use a generic Customer code for some reason and enter specifics in the Name field, but for us a customer code is unique and easily recognizable.  For this reason, I have been using the customer Name field to attach a short part description and our customer's PO Number.  This works great for us because we now can see this information when printing many reports such as those listed below:  
   1. WO-L-A   Print Work Order Status
   2. WO-L-B   Print Work Order Schedule
   3. IN-E        Print Inventory Transactions
And now I have access to my customer's PO in IN-A too!  
So, I gain valuable info and lose almost nothing.  However, if we need to go back into the work order to edit anything and press enter when on the Customer code field it OVERWRITES the customer Name field.  Then I must re-enter what I want there.  Ugg!
 
Another wish is for the customer Name field from the INVENTORY MASTER - MANUFACTURING file to used to fill in this field in WO-A. [Yes, this field MTIC_PROD_CUSNM is not currently accessable via IN-B,  but it could be.   ]  Then I could have a template stored for this purpose.  That would be AWESOME!
 
Another great thing about this idea is that it does not affect anyone negatively.  It you don't want to use it this way, just continue to use that same as you always have.  But if you want to tie together a customer's purchase order number with your work order, this is the ticket.
 
For anyone who routinely use the reports listed above, I ask that you think about the implications of this enhancement.
