AR Invoice Unit price/Discount change

Question

Hi Experts,
I need your help regarding this....
In Sales A/R process of SAP B1 8.82, we first do sales order then copy to AR Invoice to process the invoice.
At some time users do the sales order and then copy to AR invoice and modify either unit price or discount as per the customer's requirement.
I need a query to get all these type of invoices where there is a either unit price change or discount change.
I found that any AR invoice update goes to ADOC and ADO1 table, but this table populates only when the AR invoice is saved once and then opened again and modify. but if the unit price or discount has been changed at first and saved then these table does not populate.
So how can I get this changes log, from which table so that I can frame the query.
Your assistance is highly appreciated.

Hi Gordon,
I have got the solution through this query...
SELECT T0.[DocNum],  T0.[CardCode], T0.[CardName], T1.[ItemCode],   T3.[PriceBefDi] ordrprice, T3.[DiscPrcnt] ordrdisc,T1.[PriceBefDi] invprice, T1.[DiscPrcnt] invdisc
FROM [dbo].[OINV]  T0
INNER JOIN [dbo].[INV1]  T1 ON T0.DocEntry = T1.DocEntry
inner join ORDR T2 on t2.docnum=t1.baseref
INNER JOIN RDR1 T3 ON T2.DocEntry = T3.DocEntry and 
t1.itemcode=t3.itemcode
WHERE T0.[DocDate] >=[%0]
AND T1.BaseLine=T3.LineNum
and  (T1.[Price] <> T3.[Price] or  T1.[DiscPrcnt] <> T3.[DiscPrcnt])
Thanks to all
