Is there a setting on the "item maintenance" that keeps the ordered quantity on the SO the same even though part of the line item was invoiced?  This is an example, we have a SO with 3 lines, line one has a quantity of 50, line two qty of 100 different item than line 1, and line 3 with qty of 150.  We invoiced line one for 50 and line 3 for 50.  When I pull up the SO now, line 1 is gone, which it should be, line 2 is showing qty of 100 open and shows on the print preview of the SO.  Line 3, we invoiced 50 but on the SO entry screen the line is still showing qty 150 ordered and on the print preview.  I thought once a qty is billed the ordered qty is changed to reflect it, we upgraded MAS in Nov of last year and I can't remember if this just started happening then.
