The table that holds the current inventory by pallet for Assistics is ASTStockMaster. The problem is that it does not use the items and packs the Adage does. So you need to find the Warehouse Material ID. The below code will find that value. You can then use that to update inventory in ASTStockMaster.
DECLARE @Whs CHAR(4), @Item VARCHAR(9),@Pack VARCHAR(9),@MaterialID INT, @WhsMatID INT
SET @Whs='LCSF'
SET @Item='85049'
SET @Pack=''
SELECT @MaterialID=amm.materialId
FROM ASTMaterialMaster amm
WHERE amm.itemKey=@Item
AND amm.packKey=@Pack
SELECT @MaterialID
SELECT @WhsMatID=awm.warehouseMaterialId
FROM ASTWarehouseMaterial awm
WHERE awm.materialId=@MaterialID
AND awm.warehouseKey=@Whs
SELECT @WhsMatID
SELECT CAST(SUM(asm.quantity) AS INT) TotalQty
FROM ASTStockMaster asm
WHERE asm.warehouseMaterialId=@WhsMatID
--Note that if you are changing the inventory to fix a Case/Each conversion, you will need to nultiply all pallets by the same factor
--Otherwise you will specify the PalletID to update a single pallet.
BEGIN TRAN UPDATE asm SET asm.quantity=asm.quantity*10
FROM ASTStockMaster asm
WHERE asm.warehouseMaterialId=@WhsMatID
SELECT CAST(SUM(asm.quantity) AS INT) TotalQty
FROM ASTStockMaster asm
WHERE asm.warehouseMaterialId=@WhsMatID
