During Upgrade "Upgrade script not found" error.

Hi ,

I'm trying upgrade from AX 4.0 (SP1) to AX 2012 R2.

I get an error trying to live upgrade preprocessing.

Desc is "live preprocessing : InventSettlement transformation"

Method name is "inventSettlementPreUpgradeProcess"

Error message is Upgrade script not found.

There is no record InventSettlement table. I deleted all trans records.

How can I solve the problem?

Thanks..
