Step to change accounting codes to item records
We have around 80 items that have the wrong COGS, Asset and Incoming account codes assigned to them. We are unable to save the changes. When we try to save the changes, we get "The G/L impact of a transaction in a closed period cannot be changed." message. NetSuite Support says they are the ones who can only make this change.
In our sandbox environment, we were able to change the account codes if we first unlock all periods, make the change and save. Once completed, relock the periods. We understand and accept that making the change will cause income account balances to change.
