Amotisation of Cost from vendor invoices

Question

Hi All,
I have the requirement to amoritze the cost coming from the Purchase Orders over the duration of PO.
This I suppose cannot be done through Result Analysis.
I am exploring the option of Accrual Engine,but the problem is that if takes fixed amounts into consideration.Whereas my amount from the PO depends on the quantity/labor/service ordered and the IR for the same( i.e this can change over the duration of PO).
Kindly suggest as to how this process can be handled in SAP 6.0.
Thanks a lot !!

Vendor Number |   Vendor Name  |   Invoice Amount |   Amount of Invoices
10000                |      Supp 1          |     £100                |    3
10001                |      Supp 2          |     £300                |    19
10002                |      Supp 3          |     £20                  |    1
You get vendor number from RBKP, vendor name from LFA1, invoice amount - (how do you want it? amount per PO or amount per invoice in general?) - well, amount per invoice is dto in RBKP, so you have:
RBKP-LIFNR
LFA1-NAME1
either RBKP-RMWWR or RSEG-WRBTR
Now it gets a bit difficult - amount of invoices is no magic - you can create your own local variable in the query -> switch to 'Change Query XXXX: Select Field' -> EDIT -> local field -> create ... simply create a counter here.
But!! You will now have to add some date-fields to your selection-screen, otherwise this query will read every time over the wole mass of data - which surely you would not want.
Another idea: you could create your own infostructure SXXX (like S012 for MCE3) and enable a self-defined updating in MC25 ... there's documentation on the how-to in help.sap.com - but this is no substitute for a proper BI ... it's kinda poor mans BI.
