from wich tables i can get inventory valuation value, i want to custom report which is produced by 'perform inventory valuation' session ( i am using crystal report).

in LN you can use whinr110 to get the inventory transactions, and for the valuation part you need to use ticpr301, or ticpr300 whichever suits your requirement.

You can use the table for item cost ticpr300 & 301 for item cost and can take the on hand inventory from tdinv101.. these table from Baan IVc4

If you are looking for cost at a particular date then for Baan IV you need to use tdinv700 and not tdinv101. I think Ks has listed correctly
