Purchase order sort

SUGGESTED

Good afternoon

I am noticing a 'glitch' over the last couple of days and wondering if anyone else has seen it or may know of a solution/fix to look for.

Because Requisition(s) being converted to purchase order follow the sort order of the product code being used, in certain instances I have reverted to manually creating the purchase order and bringing in the lines manually utilizing the 'requirements to consider' function.  

This was working perfectly and allowed me to present the purchase order in the order that I saw fit, however, I have had several instances now where, when I go to print out the PO, the system is re-sorting this in a bizarre way; IE, instead of it printing lines 1,2,3,4 (in that order), it prints it as 1,3,4,2.

Help would be appreciated!
