Purchase Order 3 Way Match

We would like to be able to do a 3 way match in Accounts Payable using the 
number on the packing slip.  BPCS Version 6.0.04 (Unix)

At this time Account Payable Administrators use the Line number on the purchase 
order as a reference on which line was received and pay this line.

This works great until we run PUR900.  PUR900 purges all completed lines and 
will re-sequence all purchase orders that have more than 750 lines.  Once the 
re-sequence is completed A/P Administrators are not able to match the line 
numbers that were received before PUR900 has ran.  A report is provided to A/P 
Administrators (written inhouse, by our programmers) showing the line number 
previous to running PUR900 and the new line number, but using this report is 
very time consuming.  This issue is also causing a problem matching within 
Systems Accrual.

Contract purchase orders are set up once, one per Vendor.  All items are listed 
on the one contract purchase order.  Purchasing runs PUR900 monthly to purge 
all completed lines and re-sequence purchase orders over 750 lines.  This will 
enable new line items to be added to the same purchase order.

Is there a way that we can do a 3 way match using the packing slip number 
within Version 6.0.04.  We do realize that this option is available in Version 
8.

Sincerely,
