Hello Lynn. You did not specify what types of information you are looking for, and I assume you are looking for SQL. But major tables I used with SQL in the past for a few Customers are:
FROM OALC T0 [this is the Landed Cost Table Infomration]
INNER JOIN IPF2 T1 [this is the Landed Cost Line Information]
ON T0.AlcCode = T1.AlcCode
INNER JOIN OIPF T2 [this is the Landed Cost Header Information]
ON T1.DocEntry = T2.DocEntry
WHERE T2.DocDate >= [%0] AND T2.DocDate <= [%1]
The rest of the SQL is really dependent upon what type of information you are looking for.
Hope this helps!!!
